Physicochemical Properties of Cetrimonium Bromide in
Electrolytes and Nonelectrolyte Environments
Authors: Joshi Riddhi H. , Dave Nikunj N. , Joshi Tejas P.
Published: July 2023

Background:

The physicochemical properties, including the thermodynamics of
micellization studies, received much attention. Cationic surfactant cetrimonium bromide
(C16TABr) in electrolytes (sodium chloride and sodium salicylate) and nonelectrolyte
(Ethylene glycol) in an aqueous solution were examined, and interesting results were obtained.
The present investigation aims to identify a suitable combination of cationic surfactant
cetrimonium bromide + electrolytes and nonelectrolytes having the ability to alter the
size or shape of the micellar system using available methods.

Methods:

Surface tension, conductivity, viscosity, ultrasonic velocity, and dynamic light
scattering (DLS) methods at different temperatures (303-323K) were used during the experimental
research work.

Results:

The experimental results pointed out that the incorporation of electrolytes and
nonelectrolyte into the cationic surfactant affects the physicochemical properties such as
critical micelle concentration (CMC), surface tension (ST), degree of ionization (α), degree
of counterion binding (β), standard Gibbs free energy of micellization (ΔGo
m), standard entropy
of micellization (ΔSo
m), standard heat of micellization (ΔHo
m), viscosities, and acoustic
parameters. Dynamic light scattering (DLS) measurements reveal exciting facts related
to the size and shape transformation of the mixed micellar assembly. Structure modification
can be obtained by choosing right the combination of cationic surfactant cetrimonium
bromide + electrolytes (sodium chloride and sodium salicylate) and nonelectrolyte
(Ethylene glycol) ratio.

Conclusion:

It concluded that, over a threshold level, an electrolyte such as NaCl concentration
causes the micelle size to rise. The entropy of micellization goes down when a
structure-breaker (EG) is added to the water phase, and this is because the structure of the
water is changed near hydrophobic groups. The physicochemical features of cetrimonium
bromide (C16TABr) show unique behaviour under the influence of micelle-driven and micelle-
forbidden systems.
Study on the Optimal Configuration of Battery Energy Storage System in
Distribution Networks Considering Carbon Capture Units
Authors: Ma Zhiyuan , Zhao Zhenghui , Wang Yang , Hou Zhihao
Published: July 2023

Background:

The implementation of Battery Energy Storage Systems (BESSs) and carbon
capture units can effectively reduce the total carbon emissions of distribution networks. However,
their widespread adoption has been hindered by the high investment costs associated with the
BESSs and power generation costs of carbon capture units.

Objective:

The objective of this paper is to optimize the location and sizing of BESSs in distribution
networks that comprise renewable power plants and coal-fired power units with carbon capture systems.
The optimization process aims to minimize the grid’s impact from the configuration while
maximizing economic cost savings and the benefits of reducing carbon emissions.

Methods:

A bi-layer optimization model is proposed to determine the configuration of BESSs. The
upper layer of the model optimizes the size and operation strategy of the BESSs to minimize the
configuration and power generation costs, using YALMIP and CPLEX optimization tools. Carbon
emission reduction benefits are considered through deep peak-shaving and carbon tax. The lower
layer of the model aims to optimizes the placement of the BESSs to minimize voltage fluctuation
and network loss in the power grid. To achieve this, we improved the efficiency of the Nondominated
Sorting Genetic Algorithm II (NSGA-II) to update the BESS’s placement.

Results:

The IEEE33-bus and IEEE118-bus systems were utilized for simulation and comparison in
various scenarios. The findings demonstrate that the proposed configuration method can decrease
the cost of investment and power generation. Furthermore, it reduces the degree of node voltage
fluctuation and network loss in the distribution network.

Conclusion:

The study reveals that determining the optimal scale of BESSs can mitigate high energy
consumption in carbon capture systems and improve the overall performance of power systems
that integrate carbon capture technology and renewable power plants.
Cement-Based Composites Containing Carbon Nanofibers and Carbon
Nanotubes
Authors: Bajad Mohankumar Namdeorao
Published: July 2023

In cement-based composites, carbon nanotubes (CNTs) and carbon nano fibres
(CNFs) can act as crack bridging, delaying the development of nano fractures into microcracks.
Recent research on the use of CNTs and CNFs in cement-based composites was reviewed in
this paper. Earlier studies have demonstrated that cement-based composites reinforced with
CNTs/CNFs have lower porosities and superior mechanical properties to plain cement-based
composites. Using CNTs or CNFs in cement-based composites presents challenges due to their
low matrix dispersion and weak interfacial contact. Some projected future investigations were
indicated.

Low-temperature Mossbauer studies of substituted La-=SUB=-0.67-=/SUB=-Sr-=SUB=-0.33-=/SUB=-FeO-=SUB=-3-γ-=/SUB=- lanthanum ferrite
Authors: Sedykh V. D.  , Rusakov V. S.  , Gubaidulina T. V.
Published: July 2023

The valence states of Fe atoms and the formation of oxygen vacancies in substituted La0.67Sr0.33FeO3-γ orthoferrite have been studied in detail by low-temperature Mossbauer spectroscopy under oxygen removal. It has been shown that the averaged valence state of Fe atoms is not revealed with a decreasing measurement temperature. This makes it possible to reveal Fe4+ ions. The Analysis of the obtained data allows us to conclude that the presence of several Zeeman sextets associated with Fe3+ ions is related to the appearance of oxygen vacancies and Fe4+ ions in the nearest ionic surrounding of Fe ions. Using the Mossbauer data, the number of oxygen vacancies and oxygen ions has been determined for all the studied samples depending on the vacuum annealing temperature. Keywords: perovskites, substituted lanthanum ferrites, X-ray diffraction analysis, Mossbauer spectroscopy, Fe valence states, oxygen vacancies.

Authors: Buchholz Susan W , Mowbray Fabrice I , Allman Gabrielle , Verboncoeur John P , Beam Lauren , Small Leigh
Published: July 2023

Background

Nurses comprise over half of the global health care workforce, and the nursing care they provide is critical for the global population's health. High patient volumes and increased medical complexity have increased the workload and stress of nurses. As a result, the health of nurses is often negatively impacted. Wearables are used within the health care setting to assess patient outcomes; however, efforts to synthesize the use of wearable devices focusing on nurses’ health are limited.

Objective

The primary objective of our integrative review is to synthesize available data concerning the utility of wearable devices for evaluating or improving (or both) the health of nurses.

Methods

We are conducting an integrative review synthesizing data specific to wearable devices and nurses’ health. The research question for this review aims to answer how wearable devices are used to evaluate health outcomes among nurses. We searched the following electronic databases from inception until July 2022: PubMed, Embase, CINAHL, Web of Science, IEEE Explore, and AS&T. Titles and abstracts were imported into Covidence software, where citations were screened and duplicates removed. Title and abstract screening has been completed; however, full-text screening has not been started. Further screening is being conducted independently and in duplicate by 2 teams of 2 reviewers each. These reviewers will extract data independently.

Results

Search strategies have been developed, and data were extracted from 6 databases. After the removal of duplicates, we collected 8603 studies for title and abstract screening. Two independent reviewers conducted the title and abstract review, and after resolving conflicts, 277 full-text articles are available for review to determine whether they meet the inclusion criteria.

Conclusions

This integrative review will provide synthesized data to inform nurses and other stakeholders about the extent of wearable device–related work done with nurses and provide direction for future research.

Materials and methods. The description of clinical observation, results of instrumental diagnostic methods is performed. The data of histological and immunohistochemical examination of the biopsy of the patient’s brain tissue are presented.

Results and conclusion. Damage to the central nervous system in patients with HIV infection is characterized by a wide range of etiological factors. Diagnosis, in this case, is a complex task and requires a comprehensive examination of the patient, including performing computed tomography, magnetic resonance imaging of the brain, as well as cultural and molecular genetic methods of studying cerebrospinal fluid. Pathognomonic clinical manifestations and neuroradiological syndromes do not exist, and several pathogens can be released simultaneously in the biological fluids of the patient. In addition to determining the etiology of the infectious process, it is necessary to exclude a brain tumor lesion with possible biopsy, histological and immunohistochemical verification of the neoplasm.
HIV-mortality trends in the regions of Russian Federation
Authors: Savina A. A. , Lukmanov A. S. , Zemlyanova E. V.
Published: July 2023

Background. In the beginning of 2000s infectious mortality in Russian regions was predominantly determined by socially significant diseases i.e. TB, hepatitis and HIV. Over 20-year period contribution of HIV to mortality within the class «Certain infectious and parasitic diseases» increased multi-fold and it moved to the top of ranking. According to experts’ opinion, accelerated increase of mortality from HIV in the second decade of XXI century was partly conditioned by peculiarities of registration of death causes as well as insufficient antiretroviral coverage in Russian regions.

Objective. Identification of trends and features of the dynamics of mortality from HIV/AIDS in certain age groups in the subjects of the Russian Federation.

Materials and methods. Analysis of mortality indicators in Russian regions was conducted using official statistics of Rosstat and Federal Service for Surveillance in Healthcare for 2000–2021. Method of direct ranking was applied to analyze mortality from HIV-associated causes.

Results and discussion. According to official statistics, mortality from HIV-associated causes has reached its peak values in 2018. Analysis of gender differences shows that mortality in males is twice higher than in females. There are substantial differences in regional levels of mortality from HIV-associated causes. The highest mortality levels from those causes were registered in several regions of Siberia and Urals.

Conclusion. The study results show that Kemerovo region is the most unfavourable in terms of HIV-mortality. In 2021, the indicator estimated 50.4 per 100,000 that is nearly 5-fold higher than the country’s average. The number of HIV deaths in Kemerovo region was higher than cumulative number of deaths from external causes (alcohol poisonings, suicides, homicides, drownings and transport injuries). High levels of mortality from HIV were also registered in Perm territory (32.3), Irkutsk (32.2), Novosibirsk (27.5) and Sverdlovsk (26.4) regions.
Implications of labour migration on the european labour market - labour law aspects
Authors: Urdarevic Bojan
Published: July 2023

During the 21st century, migrations have become increasing-ly intense, since
they are often planned with a specific goal and could cause major social
changes. Unfortunately, since there is no definition of the term ?migrant?,
countries face a particular challenge in protecting migrant workers? right
to work. The International Labour Organization, the Council of Europe, and
the European Union have made significant contributions to establishing and
developing the migrant worker protection system. At the national level,
governments and trade unions contribute to migrant workers? protection by
adopting laws to control migrations. However, with many social, political,
and economic factors at play, countries can?t always control immigration
within their own territory. The author?s hypothesis is that the position of
migrant workers depends significantly on the host country?s im-migration and
labour policies. The paper concludes that the application of general
provisions prescribed at the international level cannot and does not fully
protect the rights of migrant workers. Given this, it is not surprising that
certain countries and trade unions have begun to protect their interests by
adopting legal regulations to manage mi-gration within their territory. The
paper identifies the fear that labour migration will negatively affect trade
unions? image in those countries where trade unions are weak and disjointed,
without real power to influence decision-makers. Finally, when analysing the
position of migrant workers in the Republic of Serbia, the author points
that the motives for labour force emigration from Serbia are extremely
strong, so even if certain changes were to be made to labour con-ditions,
there would be no reduction in emigration. This is because workers? motives
for emigration go beyond mere dissatisfaction with labour conditions, but
are rather linked to their general dissatisfaction with the quality of life
in Serbia
The exact defuzzification method under polynomial approximation of various fuzzy sets
Authors: De Sujit , Nandi Somnath
Published: July 2023

This article deals with the new approach of finding the defuzzification / ranking index of various types of fuzzy sets. Traditionally, in most of the articles on fuzzy decision making the defuzzification methods are not justified with respect to that of highest aspiration levels. This study highlights an efficient defuzzification (ranking) method which links between the gaps on the defuzzified values obtained using ??????????? and without ??????????? of fuzzy numbers. Moreover, for a given problem different membership grades are found by different researchers which are confusing and contradicts the conceptual uniqueness of fuzzy set itself. To resolve these issues, first of all, we have studied a polygonal fuzzy set by means of an interpolating polynomial function. However, in fuzzy set theory we usually seek the highest membership grade for ranking any kind of decision-making problem therefore, maximizing the polynomial function, we get the index value of the proposed fuzzy set. An artificial intelligence (AI) based solution algorithm has also been developed to find the exact defuzzified value. Indeed, considering two numerical examples we have compared these ranking values with some of the existing state of- arts under higher aspiration levels. Finally, some graphical illustrations have also been done to justify the proposed approach.
The Impact of Supervisor Relationships on Auditor Turnover Intentions Using Leader-Member Exchange Theory
Authors: Almer Elizabeth Dreike , Cannon Nathan H. , Kremin Joleen
Published: July 2023

This study expands understanding of auditor relationships and turnover by introducing the measurement of Leader-Member Exchange (LMX) to an audit setting. LMX—which considers overall quality of subordinates’ relationships with their supervisor—is well established in the management literature but has previously only been referred to as a theoretical construct in the audit literature. Utilizing a well-validated scale, we measure LMX with 167 practicing auditors. We find LMX with a single supervisor significantly impacts retention via organizational commitment. This finding is novel in the LMX literature given the unique audit setting where subordinates have multiple supervisors and transitory teams. In an exploratory analysis, we also find female subordinates form lower-quality relationships with supervisors, regardless of supervisor sex, which in turn can influence the impact of LMX on organizational commitment. Results demonstrate the value of measuring LMX in audit research and practically highlight the importance of fostering positive, strong auditor-supervisor relationships.

Designing a Classifying System for Nonprofit Organizations Using Textual Contents from the Mission Statement
Authors: Lee Heejae , Wang Xinxin , Dull Richard B.
Published: July 2023

Comparing an entity’s financial indicators with those of similar organizations can provide a better understanding of its operational and financial health. This study describes the design and implementation of a prototype multilabel classification method to categorize nonprofit organizations (NPOs) using the textual content of their mission statements to enable beneficial comparisons. Positive unlabeled learning was used to improve the classification performance of partially labeled data. Naive Bayes, Gradient Boosting, Random Forest, and Support Vector Machine (SVM) algorithms were applied to determine the most effective method for classifying NPOs. The SVM model performed best in identifying “Housing and Shelter” organizations. The SVM classifier identified organizations that were not previously classified as “Housing and Shelter” but provided housing and shelter services as a part of their programs and activities. The new classification method can help donors, grant providers, and researchers to identify similar nonprofit organizations at the operational level.
Lightening the Carbon Load: Using Management Control Systems to Manage Decarbonization Strategies
Authors: Mikes Anette , Metzner Marcel
Published: July 2023

With companies increasingly expected to undertake potentially costly climate-response strategies, we explore the roles of management control systems (MCSs) in how companies simultaneously manage their decarbonization objectives and their financial commitments. Based on research at 19 European chemical, steel, and utility corporations, we extend the concept of “proactive/reactive” response strategies by proposing three additional decarbonization strategies: wholesale green transition, green segmentation, and engagement. Second, we highlight the recursive relationship between MCSs and these strategies. We also postulate a dynamic model of MCSs evolution in the decarbonization context, whereby engagement strategies form the foundation of green segmentation and vice versa. Third, drawing on an integrative model, we propose three antecedents to companies’ response strategies relevant in this context, namely, their framing of decarbonization as an opportunity or a threat, the different perspectives on the availability of green technologies, and the different perspectives on the policy context.
Are SPAC Revenue Forecasts Informative?
Authors: Dambra Michael , Even-Tov Omri , Munevar Kimberlyn
Published: July 2023

This paper examines the informativeness of special purpose acquisition company (SPAC) revenue forecasts. We document a positive association between the compound annual growth rate in revenue forecasts and abnormal returns, retail trading, and Twitter activity in the five-day window surrounding the disclosure of a merger announcement. By contrast, we find limited evidence that institutional investors and traditional information intermediaries respond to SPAC revenue forecasts. We also find evidence that SPAC revenue forecasts positively predict future operating underperformance, stock underperformance, and class action lawsuits. Overall, our results affirm the SEC’s concerns about the attractiveness of aggressive revenue projections to retail investors.

THE ECONOMIC COMPONENT OF THE MECHANISM FOR ACTIVATION OF REGIONAL DEVELOPMENT
Authors: Bilyk Alla
Published: July 2023

The article analyzes the views of various economists on the interpretation of the term "region". Based on the generalization of these definitions, the main accents for understanding the nature of the term "regional development" are determined. The main criteria of economic zoning are clarified and a systematic division of the territory of Ukraine into economic districts, each of which has certain features of production, social, demographic, historical, etc. character, is proposed. Economic zoning is proposed as follows: Donetsk economic district, Dnipro economic district, Eastern economic district, Central economic district, Podilsky economic district, Polisky economic district, Black Sea economic district, Carpathian economic district. We believe that it is possible to take this classification as a basis in view of the realities of wartime, damages from military aggression, the consequences of business relocation and international aid.

Factors that dominate the region and have a direct impact on the functioning of the region and ensuring further economic growth of the region are investigated and systematized. The grouping of factors is carried out on the basis of affiliation to state or regional levels, as well as the external factors of influence are identified separately. External factors include the following: global trends and tendencies, requirements of international organizations, development of science and innovations. The factors of state level include: administrative-territorial reform, tax and budgetary policy, policy of regulation of the financial sector, pricing regulation policy, foreign policy. The factors of regional level include: financial support, personnel support, organizational support, information and analytical support, financial support. The role of the state in regional development is clarified, in particular, it is stated that the state is a guarantor of national interests, implements regulatory and legal regulation and stimulates economic development. A mechanism for activating regional development, which is presented in the form of consistent stages, the implementation of which will contribute to the growth of economic indicators of the region, is developed. In the first stage, it is proposed to develop a methodology for assessing the level of economic development of the region. The second stage involves the study of economic potential of the region. In the third stage, it is advisable to manage the process of activating regional development.
CLARIFICATION OF THE "REGIONAL DEVELOPMENT STRATEGY" CONCEPT
Authors: Kostyrko D. R.
Published: July 2023

The purpose of the article is to clarify the essence of the concept of regional development strategy.  The object of research is the definition of regional development strategies. The subject of research is structural and logical characteristics of regional development strategies. Research methods are: comparative and decomposition analysis, logical analysis, generalization.

The article presents the results of the author's comparative analysis of the structural and logical essence of regional development strategy definitions proposed by domestic scientists. The absence of a stable definition and the need to clarify it in view of the new meaningful characteristics that appear in modern economic conditions and should be inherent in the relevant regional development strategy are noted.

The definition of the regional development strategy has gained further development, under which it is proposed to understand the general comprehensive program of actions aimed at ensuring sustainable socio-ecological and economic development of the region and increasing its competitiveness at the national and international levels based on the effective use of resource potential, activation of local initiatives, support of promising directions development of the territory, interregional cooperation, etc., capable of ensuring economic growth in the medium and long term.

This clarification, unlike the existing ones, allows to expand the understanding of the structural and logical essence of the concept of "Regional Development Strategy" in terms of clarification of the ecological component of development, positioning at the national and international levels, activation of local initiatives.

The obtained results of the research can be used as a basis for further scientific research on improving the strategic management of the region.

Public service in wartime
Authors: Khomyshyn I.Yu.
Published: July 2023

The article is devoted to the organization of activities of public authorities under martial law. The normative legal acts adopted during the war regarding the peculiarities of the organization of labor relations of public servants and the activities of military administrations and their officials have been analyzed. The simplified procedure for admission to the civil service and the flexibility of the legislation in terms of civil service are highlighted. The opinion of scientists regarding the possibility of forming a personnel reserve and the formation of appropriate professional specialized lists of potential candidates for filling positions in the civil service was analyzed, taking into account the professional training of the specialist, his practical experience in the past, as well as the immediate place of work. Reservations were expressed regarding simplified conditions for appointment to civil service positions, which in a certain way violated the basic principles of civil service, namely stability, and professionalism. At the same time, the urgency of restoring the personnel reserve of the civil service was emphasized.The special administrative and legal status of regional military administrations is characterized, because, in addition to the specifics of formation and termination of activity, they are endowed with additional powers to introduce and ensure the implementation of measures of the legal regime and receive double subordination depending on the powers they exercise.It has been found that local self-government bodies (village, settlement, city council; its executive bodies and chairman) will continue to exercise the powers assigned to them by the Law of Ukraine «On Local Self-Government in Ukraine». There are no restrictions on such powers upon the introduction of martial law. Power decisions at the local level remain with local self government bodies, except for those where the military administrations of settlements are conducted.

The study is devoted to the possibility of increasing the efficiency of the working process in dual-fuel combustion chambers of gas turbine engines for FPSO vessels. For the first time, it is proposed to use the advantages of plasma‒chemical intensification of the combustion of hydrocarbon fuels in the dual-fuel combustion chambers, which can simultaneously operate on gaseous and liquid fuels. A design scheme of a combustion chamber with a plasma‒chemical element is proposed. A continuous type mathematical model of a combustion chamber with a plasma‒chemical element has been developed, which is based on the solution of a system of differential equations describing the processes of chemical reactions in a turbulent system, taking into consideration the initiating effect of the products of plasma‒chemical reactions on the processes of flame propagation. A modified six-stage kinetic scheme of hydrocarbon oxidation was used to simultaneously predict the combustion characteristics of the gaseous and liquid fuels, taking into account the decrease in the activation energy of carbon monoxide oxidation reactions when the products of the plasma‒chemical element are added. The results reveal that the addition of plasma‒chemical products significantly reduces CO emissions in the outlet section of the flame tube (from 25‒28 ppm to 3.9‒4.6 ppm), while the emission of nitrogen oxides remains practically unchanged for the studied combustion chamber. Further research directions are proposed to enhance the working process efficiency of a dual-fuel combustion chamber for gas turbine engines as part of the power plant of FSPO vessels.

This study aims to develop a model of interactive learning media by focusing on online activities with synchronous and asynchronous models to improve the quality of English learning. The study provides some discussion about preparing an interactive online learning by deploying various types of activities which group into synchronous and asynchronous activities. The method used in the research is research and development method which follows ADDIE model. The data collected from English skill class which include Elementary Reading and Writing and Elementary Listening and Speaking. The result of the study shows effective model for developing interactive medias for teaching English skill. It is very important to design learning activities aligned with the learning outcomes and learning objectives. To create an effective online learning environment, teachers should consider about the interactivity of the learning activities and the mode of content delivery. Both synchronous and asynchronous activities have benefits and drawback. Hence to get a maximum benefit of online learning, teachers need to combine synchronous and asynchronous activities and design which activities should be delivered in each mode.

Breast cancer continues to be one of the main priorities in global health and public health, and remains the most frequent and deadly malignant neoplasm in women worldwide. Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare type of non-Hodgkin's lymphoma, whose pathogenesis and pathophysiology are not well known, but which is seen with increasing frequency due to the increase in cosmetic procedures. To date, there are limitations in terms of knowledge about the clinical behavior of the disease, which can manifest itself in many forms, with a variable evolution time and uncertain surgical outcomes in the medium- and long-term. Based on the above, the aim of this review is to summarize evidence on the clinical considerations and surgical outcomes of breast implant-associated cancer to facilitate the identification and management of this condition. A bibliographic search was performed in the search engines and databases PubMed, ScienceDirect, Embase, EBSCO and MEDLINE. Within the clinical and surgical considerations, the type of implant used (textured), the time of the implant history, the severity of the manifestations, and the staging, must be taken into account in order to determine the opportunity for surgical intervention and neoadjuvant therapy, and to try to guarantee survival and avoid recurrence. Patients who undergo complete capsulectomy with radiotherapy have better outcomes.

Introduction: University social responsibility is present in the discourses of academics, but it fails to permeate the actions that lead to the transformation of the university, requiring a paradigm shift. At present there are conceptual confusions that make its promotion and transformative practice very difficult, in many universities it is confused with social projection, which reduces its transversal dimension. Objective: To analyze the scientific evidence related to university social responsibility in Latin America. Methods: Systematic review of the literature, between the months of August to December 2021; the search for articles was carried out in the databases: Scopus, Scielo, Doaj, Lilacs and Redalyc; the use of Descriptors in Health Sciences (DeCS) and the combination of the Boolean operators OR and AND were applied. Full texts in Spanish between the years 2015 and 2021 were considered. Results: 508 articles were obtained, which were submitted to the PRISMA methodology, selecting 20 articles, grouped into four categories according to the Social Responsibility Manual of the Úrsula Model: management, training, cognitive, and social participation. Conclusion: USR is an inalienable moral commitment, it is important in university management to promote sustainable development, with ethics and respect for human rights, the participation of committed actors is necessary, considering that it currently has a welfare and reductionist approach, scarce support, socialization and implementation and there is a need to unify criteria.
Successful embolization of ventricular arteriovenous malformation supplied by the choroidal artery: A case report and literature review
Authors: Mochizuki Tatsuki , Ryu Bikei , Sato Shinsuke , Niimi Yasunari
Published: July 2023

Background:

Ventricular arteriovenous malformations (AVMs) are localized in the ventricles and are mainly fed by the anterior choroidal artery (AChoA) and posterior choroidal artery (PChoA). Surgical resection of ventricular AVMs is difficult as the lesions are localized deep in the brain. Therefore, endovascular treatment is expected to treat ventricular AVMs. However, embolization from the AChoA and PChoA carries the risk of ischemic complications. Even though there are some major reports on embolization strategies from the choroidal arteries, embolization of these arteries remains technically challenging. In this article, we report two successful cases of ventricular AVM embolization using AChoA and PChoA.

Case Description:

Case 1: A 34-year-old male presented with intraventricular hemorrhage (IVH). Subsequently, ventricular AVM embolization in the anterior horn was performed using n-butyl-2-cyanoacrylate (NBCA) through the AChoA and medial PChoA, and complete obliteration was observed without neurological deterioration. Case 2: A 71-year-old female presented with IVH. Subsequently, ventricular AVM embolization in the lateral ventricle was performed through the AChoA and lateral PChoA with Onyx and NBCA, and partial obliteration was observed without complications. Furthermore, Gamma Knife surgery for residual lesions resulted in complete obliteration.

Conclusion:

Embolization through the choroidal arteries for ventricular AVMs is an effective curative or adjunctive treatment.
