Ultrasound diagnosis of ectopic pregnancy
Authors: Winder Simon , Reid Shannon , Condous George 
Published: December 2015

AbstractEctopic pregnancy (EP) remains the number one cause of first trimester maternal death. Traditionally, laparoscopy has been the gold standard for diagnosis of EP. The advent of high‐resolution transvaginal scan (TVS) means more clinically stable women with EPs are diagnosed earlier, well before surgery becomes necessary in many cases. Early diagnosis by TVS is therefore potentially life saving and can reduce surgical morbidity by allowing elective surgery or even non‐surgical conservative treatment options. Combining transabdominal and transvaginal scanning confers no benefit over transvaginal scanning alone. Reports that reads “…empty uterus, ectopic pregnancy cannot be excluded” should be a thing of the past. Diagnosis of EP should be based upon the positive identification of an adnexal mass using TVS rather than the absence of an intra‐uterine gestational sac. A systematic approach to scanning the early pregnancy pelvis will diagnose the vast majority of EPs at the initial scan. Ultrasound, and in particular TVS, is fast becoming the new gold standard for diagnosis of all types of EP. In modern management, laparoscopy should be seen as the operative tool of choice while TVS the diagnostic tool of choice.

AbstractThe principal aim of the IOTA project has been to develop approaches to the evaluation of adnexal pathology using ultrasound that can be transferred to all examiners. Creating models that use simple, easily reproducible ultrasound characteristics is one approach.
Spontaneous hemopertitoneum – a matter of life and death
Authors: Paoletti Debra , Robertson Meiri 
Published: December 2015

AbstractSpontaneous hemopertitoneum in pregnancy (SHiP) is a rare but potential catastrophic complication with high maternal and fetal mortality. The main cause of morbidity and mortality is delayed diagnosis and treatment. In this paper we will document the findings of an interesting case managed in our unit. We also discuss the etiology, diagnosis and management of this condition with high potential to lead to medico‐legal cases.
Sonographic visibility of breast tissue markers: a tissue phantom comparison study
Authors: Seow James Han‐Su , Phillips Michael , Taylor Donna 
Published: December 2015

AbstractRationale and objectives: Several commercially available breast tissue markers are promoted as being sonographically visible, allowing for subsequent targeting using ultrasound. The aim of this study was to compare the visibility of selected sonographic markers with the use of tissue phantoms.Materials and methods: Seven different markers were deployed into chicken and beef tissue phantoms, including a non‐sonographically enhanced marker used as a baseline. Six participants assessed their sonographic visibility and needle targeted the markers using ultrasound. The sonographic visibility of each marker was graded, with scores corrected for accuracy following mammographic review of needle targeting position.Results: Only four of the six “ultrasound enhanced” markers demonstrated statistically significant greater visibility than the non‐sonographically designed marker (P range < 0.001 to 0.04). Marker size (P < 0.001) and composition (P < 0.004) were shown to be contributing factors, with the composition of the BiomarC™ (Carbon Medical Technologies Inc, St Paul, MN, USA) demonstrating the highest conspicuity adjusted for length.Conclusion: There is significant variance in the visibility of breast tissue markers purported to be visible on ultrasound. Marker size, composition and possibly shape are contributory factors, with the utilisation of non‐metallic components associated with improved conspicuity. Our study provides a basis for further determination of optimal marker qualities, and we recommend evaluation with a larger sample size and an “in‐vivo” technique.
Vasa praevia: ultrasound diagnosis at the mid‐trimester scan
Authors: Marr Stefanie , Ashton Lindsay , Stemm Annmarie , Cincotta Robert , Chua Jacqueline , Duncombe Gregory 
Published: December 2015

AbstractBackground: Vasa praevia is a condition in which fetal vessels, unsupported by the umbilical cord or placenta, run on the fetal membranes in the lower uterine segment near the cervix. Rupture of these vessels prior to or at the time of delivery is associated with a very high perinatal mortality rate. Antenatal diagnosis of this condition with ultrasound is readily available, alters management and significantly decreases the risk of fetal loss.Materials and methods: We describe our experience of diagnosing vasa praevia at a tertiary referral ultrasound centre. The ultrasound characteristics that led to the diagnosis of vasa praevia and associated risk factors will be discussed. A guide to aid sonographers when performing an obstetric examination to help screen for this condition has been included.Conclusions: Where suspicion of vasa praevia is raised, and cannot be ruled out on transvaginal ultrasound, a third trimester scan is required.
The ‘sliding sign’ in conjunction with sonovaginography: is this the optimal approach for the diagnosis of Pouch of Douglas obliteration and posterior compartment deep infiltrating endometriosis?
Authors: Menakaya Uche , Reid Shannon , Infante Fernando , Condous George 
Published: December 2015

AbstractIntroduction: Endometriosis is a chronic peritoneal disease that may progress as a deep infiltrating lesion involving the posterior compartment of the pelvis. Efforts to improve pre‐operative knowledge of the location and extent of these lesions have resulted in the development of Transvaginal ultrasound (TVS) as the first‐line imaging modality for extra‐ovarian endometriosis. However, various techniques of TVS have been described in the literature for this purpose.Methods: In this review we will detail the evolution of TVS as the primary imaging modality in the pre‐operative diagnosis of posterior compartment deep infiltrating endometriosis (DIE). We will also discuss the potential of an emerging new real‐time diagnostic ultrasound‐based technique known as the ‘sliding sign’ in combination with office gel sonovaginography for the pre‐operative diagnosis of Pouch of Douglas obliteration and posterior compartment DIE.Conclusion: Implementation of the new real‐time dynamic, reproducible and simple ‘sliding sign’ in conjunction with SVG has the potential to challenge the current concept that traditional laparoscopy is the ‘gold standard’ modality for the diagnosis of women with posterior compartment DIE.
Cervical length for predicting preterm birth and a comparison of ultrasonic measurement techniques
Authors: O'Hara Sandra , Zelesco Marilyn , Sun Zhonghua 
Published: December 2015

AbstractIntroduction: Preterm birth is the leading cause of neonatal morbidity and mortality not attributable to congenital anomalies or aneuploidy. It has been shown that a shortened cervix is a powerful indicator of preterm births in women with singleton and twin gestations – the shorter the cervical length, the higher the risk of spontaneous preterm birth. Ultrasound measurements of the cervix are a more accurate way of determining cervical length (CL) than using a digital method.Background: There are three approaches that may be used to perform ultrasound measurements of the cervix; these are the transabdominal (TA), transperineal (TP) and the transvaginal (TV) approach. The TV approach is considered to be the gold standard. In women who are considered to be at a high risk of preterm birth it is now recommended that the cervix is measured at the mid‐trimester ultrasound using the TV ultrasound approach. For women considered to be at a historical low risk the TV scan is not recommended, however it has been found that many women who deliver a preterm baby have no known risk factors.Conclusion: There is contradictory evidence in the literature with regard to the correlation between TA, TP and TV measurements. This article provides an overview of these three approaches with a focus on the clinical value for the assessment of the maternal cervix.
Vasa Praevia: a descriptive review of existing literature and the evolving role of ultrasound in prenatal screening
Authors: Donnolley Natasha , Halliday Lesley E , Oyelese Yinka 
Published: December 2015

AbstractIntroduction: Literature addressing the feasibility of prenatal detection of vasa praevia during the mid‐trimester morphology ultrasound scan is scarce, as is a lack of consensus about the appropriate management of pregnancies once it is detected.Method: The following descriptive review will provide historical context about the clinical significance, epidemiology, diagnosis and outcomes of pregnancies complicated by vasa praevia. It will also examine the role of ultrasound in the diagnosis of vasa praevia, and will examine current evidence surrounding this debate of whether routine screening for vasa praevia is possible, beneficial, or cost‐effective. Conclusion: Finally, it will highlight the need for increased research into effective management of pregnancies at high risk of, or affected by vasa praevia to reduce fetal mortality and maternal and fetal morbidity associated with the condition.
The use of middle cerebral artery Doppler ultrasonography to guide delivery of a viable pregnancy complicated by metastatic gestational chroriocarinoma
Authors: Thagard Andrew S , Dubil Elizabeth A , Lee Amy , Allard Jay , Zelig Craig M 
Published: December 2015

AbstractBackground: Choriocarcinoma is a rare, aggressive subtype of gestational trophoblastic neoplasia. The diagnosis of metastatic choriocarcinoma in the setting of a viable intrauterine pregnancy is exceedingly rare and often associated with feto‐maternal hemorrhage.Case: An otherwise healthy Gravida 1 Para 0 at 34 weeks gestational age presented with metastatic choriocarcinoma and a viable fetus. Measured Doppler peak systolic velocity of the middle cerebral artery was used to detect fetal anemia, thus optimising the timing of delivery.Conclusion: This is the first case report to our knowledge using Doppler ultrasonography to detect fetal anemia in an effort to guide delivery in a case of choriocarcinoma diagnosed during pregnancy. If choriocarcinoma is diagnosed during pregnancy, middle cerebral artery Doppler ultrasonography may serve as a critical tool to help detect anemia, allowing pregnancy prolongation to promote fetal maturity while screening for the development of feto‐maternal hemorrhage.
Ultrasound assessment of fetal cardiac function

Published: December 2015

AbstractIntroduction: Fetal heart evaluation with US is feasible and reproducible, although challenging due to the smallness of the heart, the high heart rate and limited access to the fetus. However, some cardiac parameters have already shown a strong correlation with outcomes and may soon be incorporated into clinical practice.Materials and Methods: Cardiac function assessment has proven utility in the differential diagnosis of cardiomyopathies or prediction of perinatal mortality in congenital heart disease. In addition, some cardiac parameters with high sensitivity such as MPI or annular peak velocities have shown promising results in monitoring and predicting outcome in intrauterine growth restriction or congenital diaphragmatic hernia.Conclusion: Cardiac function can be adequately evaluated in most fetuses when appropriate expertise, equipment and time are available. Fetal cardiac function assessment is a promising tool that may soon be incorporated into clinical practice to diagnose, monitor or predict outcome in some fetal conditions. Thus, more research is warranted to further define specific protocols for each fetal condition that may affect cardiac function.
Malposition of Double Lumen Bicaval Venovenous Extracorporeal Membrane Oxygenation (VV ECMO) cannula resulting in hepatic venous congestion
Authors: Yastrebov Konstantin , Kapalli Tejo 
Published: December 2015

AbstractIntroduction: Optimal positioning of double lumen bicaval canula for extracorporeal membrane oxygenation (ECMO) support used as a rescue measure in refractory hypoxaemia is essential to facilitate adequate oxygenation, prevent recirculation and avoid complications.Method: Echocardiography via transoesophageal or transthoracic windows can be used as guidance and as a surveillance technique to prevent cannula malposition. We describe a case of Double‐Lumen Bicaval VV ECMO cannula malposition leading to a massive retrograde hepatic venous flow. Conclusion: Rapid echocardiographic diagnosis was pivotal in preventing potentially fatal complications.
Paediatric Iliopsoas abscess: A case report
Authors: Elliott Carla 
Published: December 2015

AbstractIntroduction: Iliopsoas abscess is an uncommon condition in the paediatric population. The clinical presentation is variable and may be confused with other conditions such as septic arthritis, osteomyelitis and appendicular abscess. A suspicion of iliopsoas abscess requires a prompt diagnosis so that rapid management and treatment can be undertaken.Discussion: This case describes the presence of an iliopsoas abscess in a paediatric patient presenting to the emergency department within a rural community. Due to the variability in clinical presentation imaging studies are necessary to distinguish an iliopsoas abscess from other inflammatory processes. Ultrasound is often the modality of choice. Imaging guided percutaneous drainage and/or aspiration and the administration of intravenous antibiotics are minimally invasive modern techniques providing a safe treatment options in the presence of an iliopsoas abscess.Conclusion: Iliopsoas abscess is an uncommon condition in the paediatric population. Due to the variability in clinical presentation, imaging, and in particular, ultrasound play a vital role in the diagnosis of cases with a high suspicion of abscess formation. Accurate diagnosis leads to a rapid treatment plan, avoiding further insult.
A futuristic vision of pocket ultrasound machines: watch this space
Authors: Woo Joyce Su Ling , Magotti Robert , Benzie Ronald 
Published: December 2015

AbstractIntroduction: Australian medical ultrasound started in 1959 with the establishment of the Ultrasonics Institute. Since then the technology has advanced tremendously. We are now not only able to obtain clearer images on high specification ultrasound machines but also on pocket‐sized ultrasound machines that are compact, lightweight and affordable.Method: The following descriptive review will examine the indication for use of pocket ultrasound machines in different clinical settings as well as provide evidence of its image clarity and accuracy. Potentially eligible studies were sought primarily through searches of the electronic databases PubMed, Medline (1996–Present), Embase (1996–Present) and Cochrane Library.Conclusion: Pocket ultrasound machines, with appropriate ultrasound knowledge and training, can be incorporated successfully in patient management. The addition of point‐of‐care ultrasound has been shown to improve management recommendations and outcomes.

Published: December 2015

AbstractHysterosalpingo contrast sonography (HyCoSy) is a commonly performed procedure in the investigation of infertility. Infection is an uncommon complication of this procedure. Should it occur, it is generally mild and amenable to outpatient treatment with oral antibiotics. We present a case of an immunosuppressed woman who underwent HyCoSy for investigation of secondary infertility and developed life‐threatening sepsis with Group A streptococcus.
Ultrasound guided therapeutic injections of the cervical spine and brachial plexus
Authors: Cormick Wes 
Published: December 2015

AbstractIntroduction: Recent applications in ultrasound imaging include ultrasound assessment and ultrasound guided therapeutic injections of the spine and brachial plexus.Discussion: Ultrasound is an ideal modality for these regions as it allows accurate safe and quick injection of single or multiple sites. It has the added advantages of lack of ionising radiation, and can be done without requiring large expensive radiology equipment.Conclusion: Brachial plexus pathology may be present in patients presenting for shoulder symptoms where very little is found at imaging the shoulder. It is important to understand the anatomy and normal variants that may exist to be able to recognise when pathology is present. When pathology is demonstrated it is easy to do a trial of therapy with ultrasound guided injection of steroid around the nerve lesion. This review will outline the normal anatomy and variants and common pathology, which can be amenable to ultrasound guided injection of steroid.
Imaging of slings and meshes
Authors: Shek Ka Lai , Dietz Hans Peter 
Published: December 2015

AbstractThe popularity of imaging in pelvic floor medicine continues to increase. Among the various modalities, ultrasound is superior as it is cheap, safe, easily accesible and simple, resulting in high patient compliance. It is the only technique that allows imaging of modern wide‐weave polypropylene sling or mesh implants, and imaging of such implants is commonly required due to the popularity of surgical techniques that involve the placement of slings and meshes. This review article will discuss the role of translabial ultrasound in the evaluation of synthetic implants used in the treatment of urinary incontinence and pelvic organ prolapse.
Increased endometrial vascularity and intraoperative haemorrhage among women undergoing surgical evacuation for retained product of conception
Authors: Ebrahimi Maryam , Trivedi Amarendra 
Published: December 2015

AbstractThe aim of this study was to ascertain the incidence of “increased endometrial vascularity” recorded in the ultrasound scan reports, in the context of RPOC and correlate this finding with the incidence of life threatening intra‐operative bleeding.Ultrasound scan reports sometimes mention the presence of increased endometrial / sub‐endometrial vascularity in the context of retained products of conception or secondary post partum haemorrhage. This raises the possibility of serious intra‐operative haemorrhage in the minds of the junior doctors because of the possibility of arterio‐venous malformation. This retrospective case series was designed to find the incidences of increased endometrial vascularity and severe intra‐operative haemorrhage in the patients with RPOC in the south eastern part of Melbourne population. The study found that the incidence of increased endometrial vascularity was 7.57% and none of these patients suffered severe intra‐operative haemorrhage. A literature survey revealed that there were few studies on this topic.
Congenital Epulis: a clinical case presentation
Authors: Sweeney Kristie , Spurway Jacqueline , Mein Brendan , Magotti Robert , Benzie Ron , Challis Daniel , Henry Guy 
Published: December 2015

AbstractCongenital Epulis (CE) is a rare, benign tumour of the mucosa of the mouth in a neonate. It presents as an intraoral tumour and is rarely diagnosed prenatally. Complications include neonatal airway compromise, difficulty feeding and aesthetic considerations. Ultrasound is useful in aiding decisions regarding site, age, method of delivery and preparing parents and staff for the appearances of the tumour at birth. We present a case where CE was identified at 35 weeks gestational age during a routine third trimester prenatal ultrasound.The patient was scanned at a rural centre, referred to a tertiary institution for follow up and delivered at a specialist perinatal surgical centre, in preparation for neonatal surgery. The outcome was excellent and this case is a good example of multi‐centre cooperation.
Echocardiographic assessment of left ventricular outflow tract diameter in preterm infants
Authors: Beker Friederike , Davis Peter G , Sehgal Arvind , Rogerson Sheryle 
Published: December 2015

AbstractIntroduction: Left ventricular output (LVO) measurement is an important part of the echocardiographic assessment of cardiac function in preterm infants. The accurate measurement of left ventricular outflow tract diameter (LVOD) is key to the calculation of LVO. Given the lack of an appropriate gold standard, we used right ventricular output (RVO) as the comparator and sought to identify the most accurate method of determining LVO in preterm infants.Methods: We studied stable preterm infants without significant cardiac shunts. LVOD was measured at the aortic valve, the aortic sinus and at the sinotubular junction. LVOs were calculated and the precision and accuracy of each was determined relative to the RVO using the Bland‐Altman method. Results: 52 infants were included in this analysis. The mean difference between RVO and LVO was largest when LVOD was measured at the aortic valve and aortic sinus, +106 and −115 ml/kg/min, respectively, and smallest when measured at the sinotubular junction, 9 ml/kg/min. Limits of agreement between RVO and LVO were narrowest when LVOD was measured at the STJ. Conclusion: LVOD measurement at the sinotubular junction provides more precise and accurate measurement of LVO, in comparison to RVO, than measurement at the aortic valve or the aortic sinus.
Sonographic diagnosis of Obstructed Hemivagina and Ipsilateral Renal Anomaly Syndrome: a report of two cases
Authors: Mishra Neetika , Ng Stanley 
Published: December 2015

AbstractObstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare urogenital anomaly. Patients typically present at puberty, shortly after menarche with increasing pelvic pain, dysmenorrhea and pelvic mass. There may be a known history of unilateral renal agenesis. Diagnosis can usually be established by ultrasound or magnetic resonance imaging. Resection of the vaginal septum is the treatment of choice. Early diagnosis and treatment can relieve symptoms, prevent complications and preserve fertility. We present two cases of OHVIRA syndrome diagnosed by ultrasound to promote recognition of this rare but important condition.
