Published: October 2019

Background:The aim of the study was to characterize the clinical profile of patients with anterior communicating artery (ACoA) aneurysms and examine potential correlations between clinical findings, aneurysm morphology, and outcome.Methods:A review of medical records and diagnostic neuroimaging reports of patients treated at a neurosurgical service in Porto Alegre, Brazil, between August 2008 and January 2015 was performed.Results:During the period, 100 patients underwent surgery for ACoA aneurysms. Fifteen had unruptured aneurysms and 85 had ruptured aneurysms. Ruptured aneurysms had a higher aspect ratio than unruptured ones (2.37 ± 0.71 vs. 1.93 ± 0.51,P= 0.02). Intraoperative rupture occurred in 3%, and temporary clipping was performed in 15%. Clinical vasospasm occurred in 43 patients with ruptured aneurysms (50.6%). Overall, mortality was 26%; 25 patients in the ruptured group (29.4%) and one in the unruptured group (6%). The Glasgow Outcome Scale (GOS) was favorable (GOS 4 or 5) in 54% of patients, significantly more so in those with unruptured aneurysms (P= 0.01). In patients with ruptured aneurysms, mortality was associated with preoperative Hunt and Hess (HH) score (P< 0.001), hydrocephalus (P< 0.001), and clinical complications (P< 0.001). Unfavorable outcomes were associated with HH score (P< 0.001), Fisher grade (P= 0.015), clinical vasospasm (P= 0.012), external ventricular drain (P= 0.015), hydrocephalus (P< 0.001), and presence of clinical complications (P= 0.001). In patients with unruptured aneurysms, presence of clinical complications was the only factor associated with mortality (P< 0.001).Conclusion:Despite advances in the management of subarachnoid hemorrhage and surgical treatment of aneurysms, mortality is still high, especially due to clinical complications.

Published: October 2019

Objectif : La chirurgie bariatrique est le traitement le plus efficace pour la réduction de poids à long terme chez les patients souffrant d’obésité pathologique. Il existe une abondante littérature et des croyances liant les causes d’échec de perte de poids aux aspects techniques ou hormonaux, mais aussi aux aspects alimentaires, ou au style de vie sédentaire.
Méthodes : Nous avons envoyé aux patients un autoquestionnaire simple pour évaluer l’observance des conseils nutritionnels ou d’activité physique donnés par notre équipe au cours de la période préopératoire. Les patients ayant reçu le questionnaire ont bénéficié d’une chirurgie bariatrique de septembre 2013 à août 2016. Les questionnaires ont été recueillis lors d’une réunion annuelle de suivi en septembre 2017. Cent quarante-quatre patients sur 750 ont répondu à ce questionnaire et 133 avaient eu une sleeve gastrectomie par laparoscopie.
Résultats : Soixante-quatre pour cent des patients avaient une activité physique qui durait moins de 30 minutes par jour. Parmi les patients, 46 % ont déclaré une faim anormale, 60 % avaient terminé leur repas en moins de 20 minutes, 18,7 % avaient une consommation régulière de chewinggum, 32 % avaient plus de trois collations par semaine, 66 % avaient une consommation excessive de sucre plus de deux fois par semaine et 18 % moins de trois repas par jour. Le genre féminin, une durée de repas inférieure à 20 minutes, et moins de trois repas par jour étaient significativement liés à une perte d’IMC plus faible, 13,4 vs 15,8 kg/m2, p = 0,0049 ; 13,5 vs 14,3 kg/m2, p = 0,0002 ; 12,2 vs 14,3 kg/m2, p = 0,0307 respectivement.
Conclusion : Le genre féminin, une alimentation rapide et moins de trois repas par jour sont associés à une perte de poids plus faible chez les patients ayant bénéficié d’une chirurgie bariatrique il y a plus de deux ans.

OBJECTIVEChildren with intracranial arteriovenous malformations (AVMs) undergo digital DSA for lesion surveillance following their initial diagnosis. However, DSA carries risks of radiation exposure, particularly for the growing pediatric brain and over lifetime. The authors evaluated whether MRI enhanced with a blood pool ferumoxytol (Fe) contrast agent (Fe-MRI) can be used for surveillance of residual or recurrent AVMs.METHODSA retrospective cohort was assembled of children with an established AVM diagnosis who underwent surveillance by both DSA and 3-T Fe-MRI from 2014 to 2016. Two neuroradiologists blinded to the DSA results independently assessed Fe-enhanced T1-weighted spoiled gradient recalled acquisition in steady state (Fe-SPGR) scans and, if available, arterial spin labeling (ASL) perfusion scans for residual or recurrent AVMs. Diagnostic confidence was examined using a Likert scale. Sensitivity, specificity, and intermodality reliability were determined using DSA studies as the gold standard. Radiation exposure related to DSA was calculated as total dose area product (TDAP) and effective dose.RESULTSFifteen patients were included in this study (mean age 10 years, range 3–15 years). The mean time between the first surveillance DSA and Fe-MRI studies was 17 days (SD 47). Intermodality agreement was excellent between Fe-SPGR and DSA (κ = 1.00) but poor between ASL and DSA (κ = 0.53; 95% CI 0.18–0.89). The sensitivity and specificity for detecting residual AVMs using Fe-SPGR were 100% and 100%, and using ASL they were 72% and 100%, respectively. Radiologists reported overall high diagnostic confidence using Fe-SPGR. On average, patients received two surveillance DSA studies over the study period, which on average equated to a TDAP of 117.2 Gy×cm2 (95% CI 77.2–157.4 Gy×cm2) and an effective dose of 7.8 mSv (95% CI 4.4–8.8 mSv).CONCLUSIONSFe-MRI performed similarly to DSA for the surveillance of residual AVMs. Future multicenter studies could further investigate the efficacy of Fe-MRI as a noninvasive alternative to DSA for monitoring AVMs in children.

OBJECTIVESpinal cord stimulation has been shown to improve pain relief and reduce narcotic analgesic use in cases of complex refractory pain syndromes. However, a subset of patients ultimately undergoes removal of the spinal cord stimulator (SCS) system, presumably because of surgical complications or poor efficacy. This retrospective study addresses the paucity of evidence regarding risk factors and underlying causes of spinal cord stimulation failures that necessitate this explantation.METHODSIn this retrospective single-center review, 129 patients underwent explantation of SCS hardware during a 9-year period (2005–2013) following initial placement at the authors’ institution or elsewhere. Medical history, including indication of implantation, device characteristics, revision history, and reported reasons for removal of hardware, were reviewed.RESULTSThe 74 (57%) women and 55 (43%) men were a median of 49 years old (IQR 41–61 years) at explantation; the median time to explantation was 20 months (IQR 7.5–45.5 months). Thoracic or upper lumbar leads were placed in 89.9% of patients primarily for the diagnosis of postsurgical failed–back surgery syndrome (70.5%), chronic regional pain syndrome (14.7%), and neuropathic pain (8.5%). More than half of patients were legally disabled. Initial postoperative reduction in pain was reported in 81% of patients, and 37.8% returned to work. Among 15 patients with acute postsurgical complications (12 infections, 2 hemorrhages, 1 immediate paraplegia), the median time to removal was 2 months. Primary reasons for hardware removal were lack of stimulation efficacy (81%), electrode failure due to migration (14%), and allergic reactions to implanted hardware in 2 patients. The 72 patients who underwent formal psychiatric evaluation before implantation were affected by high rates of major depression (64%), anxiety (34%), posttraumatic stress disorder (PTSD) (12%), drug or alcohol abuse (12%), and physical or sexual abuse (22%).CONCLUSIONSThe authors’ findings provide insight regarding the mechanisms of spinal cord stimulation failure that resulted in total removal of the implanted system. The relationship between spinal cord stimulation failure and certain psychiatric disorders, such as PTSD, depression, and anxiety, is highlighted. Ultimately, this work may shed light on potential avenues to reduce morbidity and improve patient outcomes.

OBJECTIVEThe importance of maintaining mean arterial pressure (MAP) > 85 mm Hg for patients with acute spinal cord injury (SCI) is well documented, because systemic hypotension greatly increases the risk of secondary SCI. Current literature focuses on the ICU setting; however, there is a paucity of data describing the changes in MAP in the operating room (OR). In the present study, the authors investigated the incidence of intraoperative hypotension for patients with acute traumatic SCI as well as any associated factors that may have impacted these findings.METHODSThis retrospective study was performed at a level 1 trauma center from 2015 to 2016. All patients with American Spinal Injury Association (ASIA) score A–D acute traumatic SCIs from C1 to L1 were identified. Those included underwent spinal instrumentation and/or laminectomy decompression. Associated factors investigated include the following: age, body mass index, trauma mechanism of injury, Injury Severity Score, level of SCI, ASIA score, hospital day of surgery, total OR time, need for laminectomy decompression, use of spinal fixation, surgical positioning, blood loss, use of blood products, length of hospital stay, length of ICU stay, and discharge disposition. Intraoperative minute-by-minute MAP recordings were used to determine time spent in various MAP ranges.RESULTSThirty-two patients underwent a total of 33 operations. Relative to the total OR time, patients spent an average of 51.9% of their cumulative time with an MAP < 85 mm Hg. Furthermore, 100% of the study population recorded at least one MAP measurement < 85 mm Hg. These hypotensive episodes lasted a mean of 103 cumulative minutes per operative case. Analysis of associated factors demonstrated that fall mechanisms of injury led to a statistically significant increase in intraoperative hypotension compared to motor vehicle collisions/motorcycle collisions (p = 0.033). There were no significant differences in MAP recordings when analyzed according to all other associated factors studied.CONCLUSIONSThis is the first study reporting the incidence of intraoperative hypotension for patients with acute traumatic SCIs, and the results demonstrated higher proportions of relative hypotension than previously reported in the ICU setting. Furthermore, the authors identified that every patient experienced at least one MAP below the target value, which was much greater than the initial hypothesis of 50%. Given the findings of this study, adherence to the MAP protocol intraoperatively needs to be improved to minimize the risk of secondary SCI and associated deleterious neurological outcomes.

OBJECTIVELeiomyogenic tumor of the spine is rare with limited published information. Here, the authors report the clinical features and long-term surgical outcomes and investigate the prognostic factors affecting disease-free survival (DFS).METHODSTwelve patients presented to the authors’ institution for surgical treatment from January 2005 to December 2018. The clinical characteristics and outcomes were retrospectively reviewed, and the DFS rate was estimated using the Kaplan-Meier method. The log-rank test was used to identify the potential prognostic factors, with p < 0.05 considered statistically significant.RESULTSThe mean patient age was 49.7 ± 12.9 years (range 22–73 years). Four patients underwent marginal en bloc resection, and 8 patients underwent conventional piecemeal resection. Pathological diagnosis revealed leiomyosarcoma in 9 patients and leiomyoma in 3 patients. Three patients had tumor recurrence at a mean follow-up of 10.4 months (range 7.0–15.0 months), while 4 developed metastases at an average of 13.8 months (range 5.5–21.3 months) postoperatively. During the mean follow-up of 33.7 months (range 9.6–78.5 months), the estimated 1- and 5-year DFS rates were 66.7% and 38.2%, respectively. Albumin loss > 20 g/L after surgery, Ki-67 positivity > 10%, and piecemeal resection were correlated with worse DFS.CONCLUSIONSSurgical management of spinal leiomyogenic tumors is challenging due to the high rate of recurrence and metastases. En bloc resection should be performed in eligible patients. Albumin loss > 20 g/L and the Ki-67 index may be independent factors affecting prognosis.
