Background: Tophaceous gout is a severe form of gout that results in the formation of large nodules, or tophi, in the affected joints and surrounding tissues. Gouty tophi in the spine have a constellation of presentations that often mimic other pathologies and may not be easily discernable from more common pathologic processes., Observations: A 47-year-old female with a history of chronic renal disease, obesity, gout, inflammatory polyarthritis, and multiple sclerosis presented with 6 months of low-back pain and lumbar radiculopathy affecting the right lower extremity. A lumbar magnetic resonance imaging study revealed right foraminal stenosis and spondylolisthesis at levels L4-5. An intraspinal extradural mass was noted adjacent to the traversing right L5 and exiting right L4 nerve roots. A bilateral decompressive laminectomy, facetectomy, and foraminotomy of L4-5 was performed. A calcific, chalky-white mass was discovered in the foramen, and pathology determined the specimen to be a gout tophus. Postoperatively, the patient endorsed the resolution of her preoperative symptoms, which have not returned on follow-up., Lessons: Reports of gouty depositions compressing the spinal cord in the current literature are relatively rare. Although the diagnosis of gouty tophi can only be confirmed histologically, patient history may serve as a helpful diagnostic tool.

Background: Mechanical thrombectomy failure (MTF) occurs in approximately 15% of cases., Objective: To investigate factors that predict MTF., Methods: This was a retrospective review of prospectively collected data from the Stroke Thrombectomy and Aneurysm Registry. Patients who underwent mechanical thrombectomy (MT) for large vessel occlusion (LVO) were included. Patients were categorized by mechanical thrombectomy success (MTS) (≥mTICI 2b) or MTF (

Introduction: Endovascular mechanical thrombectomy (MT) is an established treatment for large vessel occlusion strokes with a National Institutes of Health Stroke Scale (NIHSS) score of 6 or higher. Data pertaining to minor strokes, medium, or distal vessel occlusions, and most effective MT technique is limited and controversial., Methods: A multicenter retrospective study of all patients treated with MT presenting with NIHSS score of 5 or less at 29 comprehensive stroke centers. The cohort was dichotomized based on location of occlusion (proximal vs. distal) and divided based on MT technique (direct aspiration first-pass technique [ADAPT], stent retriever [SR], and primary combined [PC]). Outcomes at discharge and 90 days were compared between proximal and distal occlusion groups, and across MT techniques., Results: The cohort included 759 patients, 34% presented with distal occlusion. Distal occlusions were more likely to present with atrial fibrillation (p = 0.008) and receive IV tPA (p = 0.001). Clinical outcomes at discharge and 90 days were comparable between proximal and distal groups. Compared to SR, patients managed with ADAPT were more likely to have a modified Rankin Scale of 0-2 at discharge and at 90 days (p = 0.024 and p = 0.013). Primary combined compared to ADAPT, prior stroke, multiple passes, older age, and longer procedure time were independently associated with worse clinical outcome, while successful recanalization was positively associated with good clinical outcomes., Conclusions: Proximal and distal occlusions with low NIHSS have comparable outcomes and safety profiles. While all MT techniques have a similar safety profile, ADAPT was associated with better clinical outcomes at discharge and 90 days.

Background: Childhood cancer survivors need regular, long-term survivor care. The Children's Oncology Group (COG) recommends that pediatric patients receive ongoing, evidence-based surveillance for late effects, beginning 2 years after the completion of cancer therapy. However, at least a third of survivors are not engaging in long-term survivorship care. This study assessed facilitators and barriers to follow-up survivorship care through the perspectives of pediatric cancer survivor clinic representatives., Methods: As part of a hybrid implementation-effectiveness trial, a representative from 12 participating pediatric cancer survivor clinics completed a survey about site characteristics and a semi-structured interview on facilitators and barriers to survivor care delivery at their institution. Interviews were grounded in the socio-ecological model (SEM) framework and utilized a fishbone diagram to understand what facilitates and impedes survivor care. We ran descriptive statistics and conducted thematic analyses of the interview transcripts to create two meta-fishbone diagrams., Results: All participating clinics (N = 12) have existed for at least 5 years (mean = 15, median = 13, range = 3-31), and half (n = 6, 50%) reported seeing more than 300 survivors annually. In the fishbone diagram, the top facilitators were in the SEM domain of organization, specifically with familiar staff (n = 12, 100%), resource utilization (n = 11, 92%), dedicated survivorship staff (n = 10, 83%), and clinic processes (n = 10, 83%). Common barriers were across the domains of organization, community, and policy, which included distance/transportation to the clinic (n = 12, 100%), technology limits (n = 11, 92%), scheduling issues (n = 11, 92%), and insufficient funding/insurance (n = 11, 92%)., Conclusion: Clinic staff and provider perceptions are instrumental in understanding multilevel contextual issues related to survivor care delivery for pediatric cancer survivor clinics. Future research can aid in developing education, processes, and services to promote cancer survivor follow-up care., (© 2023 Wiley Periodicals LLC.)

Objective: The role of endovascular mechanical thrombectomy (MT) in patients presenting with "minor" stroke is uncertain. We aimed to compare outcomes after MT for ischemic stroke patients presenting with National Institutes of Health Stroke Scale (NIHSS) 5 and - within the low NIHSS cohort - identify predictors of a favorable outcome, mortality, and symptomatic intracranial hemorrhage (ICH)., Methods: We retrospectively analyzed a prospectively maintained, international, multicenter database., Results: The study cohort comprised a total of 7568 patients from 29 centers. NIHSS was low (<5) in 604 patients (8%), and > 5 in 6964 (92%). Patients with low NIHSS were younger (67 + 14.8 versus 69.6 + 14.7 years, p < 0.001), more likely to have diabetes (31.5% versus 26.9%, p = 0.016), and less likely to have atrial fibrillation (26.6% versus 37.6%, p < 0.001) compared to those with higher NIHSS. Radiographic outcomes (TICI > 2B 84.6% and 84.3%, p = 0.412) and complication rates (8.1% and 7.2%, p = 0.463) were similar between the low and high NIHSS groups, respectively. Clinical outcomes at every follow up interval, including NIHSS at 24 h and discharge, and mRS at discharge and 90 days, were better in the low NIHSS group, however patients in the low NIHSS group experienced a relative decline in NIHSS from admit to discharge. Mortality was lower in the low NIHSS group (10.4% versus 24.5%, p < 0.001)., Conclusions: Relative to patients with high NIHSS, MT is safe and effective for stroke patients with low NIHSS, and it is reasonable to offer it to appropriately selected patients presenting with minor stroke symptoms. Our findings justify efforts towards a randomized trial comparing MT versus medical management for patients with low NIHSS., (Copyright © 2023 Elsevier B.V. All rights reserved.)

Background: Cancer survivors who received gonadotoxic treatment are at-risk for future infertility and may desire a fertility status assessment (FSA), defined as semen analysis for males and consultation with a reproductive specialist for females. The purpose of this study was to describe the proportion of, and factors associated with, interest in FSA among young adult survivors of childhood cancer., Methods: This retrospective single-institution review included patients with prior gonadotoxic treatment, aged 18-25 years and >1 year from cancer treatment completion, who received a fertility-focused discussion during survivorship. Documentation of interest in and completion of FSA, worry about infertility, sociodemographic, and clinical characteristics were abstracted from medical records. Multivariable logistic regression was performed to calculate odds ratios (OR) and 95% confidence intervals (95%CI) for factors associated with interest in FSA., Results: Survivors (N = 259) were on average 19.2 ± 1.2 years at their fertility discussion; 55.6% were male and 57.9% non-Hispanic white. Interest in FSA was reported by 50.7% of males and 46.1% of females. Factors related to interest in FSA for males and females respectively, included worry about infertility (OR 2.40, 95%CI 1.11-5.27, p = 0.026 and OR 4.37, 95%CI 1.71-12.43, p = 0.003) and ≥2 fertility discussions (OR 3.78, 95%CI 1.70-8.75, p = 0.001 and 2.45, 95%CI 1.08-5.67, p = 0.033). Among males, fertility preservation consult/procedure at diagnosis (OR 3.02, 95%CI 1.09-9.04, p = 0.039) and high-risk for infertility (OR 2.47, 95%CI 1.07-5.87, p = 0.036) were also associated with interest in FSA., Conclusions: Cancer survivors are interested in FSA, particularly those who have had repeated fertility-focused discussions during survivorship care and who report worry about infertility., (© 2022 The Authors.

Purpose: Cancer survivors with a history of gonadotoxic treatment are at risk for future infertility and reproductive concerns, including worry about infertility. The purpose of this study was to describe factors associated with fertility-related worry among emerging adult survivors of childhood cancer., Methods: This chart review included patients aged 18.00-25.99 years and > 1 year from cancer treatment completion with a history of gonadotoxic treatment. Survivors were offered structured fertility-focused discussions at age ≥ 18 years, which assessed worry about future infertility. Data from this discussion (i.e., reported fertility-related worry (yes/no), sociodemographic, and clinical characteristics were abstracted from the medical record. Multivariable logistic regression with backwards elimination was used to calculate odds ratios (OR) and 95% confidence intervals (95%CI) for factors associated with fertility-related worry., Results: Survivors (N = 249) were a mean age of 19.1 ± 1.2 years at initial fertility discussion; 55.8% were male, 58.2% non-Hispanic White, and 27.3% were at high risk for future treatment-related infertility. Fertility-related worry was reported by 66.3% of survivors. Factors related to worry on multivariable analysis included female sex (OR: 2.64, 95%CI: 1.44-4.96, p = .002), solid tumor diagnosis (OR: 2.31, 95%CI: 1.15-4.71, p = .019), moderate and high risk of infertility (OR: 2.94, 95%CI: 1.23-7.64, p = .02; OR: 3.25, 95%CI: 1.55-7.17, p = .002), and ≥ 2 fertility discussions during survivorship care OR: 2.71, 95%CI: 1.46-5.20, p = .002)., Conclusions: Two-thirds of emerging adult cancer survivors expressed worry about future infertility, which has been linked to a variety of adverse quality of life outcomes. Survivors who are worried about infertility may benefit from psychological interventions., (© 2022.

Allogeneic hematopoietic cell therapy (HCT) is an established cure for sickle cell disease (SCD); however, HCT conditioning regimens are known to be gonadotoxic. Anti-mullerian hormone (AMH) measures ovarian reserve, and follicle-stimulating hormone (FSH) defines premature ovarian insufficiency (POI) at values >40 mIU/mL in pubertal females. The present study was conducted to assess ovarian reserve and function before and after transplantation in pediatric and adolescent females with SCD treated with allogeneic HCT between January 2015 and June 2020 at Children's Healthcare of Atlanta. In this retrospective review of 17 females age <21 years with SCD who had AMH levels measured at baseline and at 2 years post-HCT, AMH levels were categorized as normal, low, or undetectable, and FSH levels were measured and used to identify pubertal females who had developed POI. Demographic and treatment data were abstracted from the institutional database and medical records, and a descriptive statistical analysis was conducted. Of the 17 patients in the study cohort, 14 had been treated with hydroxyurea and 3 had chronic transfusions but with no significant iron overload. AMH levels were normal in 15 patients (88%) and low in 2 patients (12%) at baseline. The median age at HCT was 7.5 years (range, 3.7 to 20.3 years), and 14 patients (82%) underwent matched related donor HCT. After HCT, 15 patients (88%) had undetectable AMH and 2 (12%) had low AMH, with no apparent differences by HCT conditioning regimen. No pubertal patients had POI at baseline, whereas 55% of pubertal patients had progressed to POI by 2 years post-HCT. In this cohort, the majority of females had normal AMH levels at baseline but undetectable levels after HCT. Females with SCD considering HCT should be counseled about the treatment-related risk of gonadal dysfunction. © 2022 American Society for Transplantation and Cellular Therapy.

Objective: Although younger adults have been shown to have better functional outcomes after mechanical thrombectomy (MT) for acute ischemic stroke (AIS), the significance of this relationship in the adolescent and young adult (AYA) population is not well defined given its undefined rarity. Correspondingly, the goal of this study was to determine the prognostic significance of age in this specific demographic following MT for large-vessel occlusions., Methods: A prospectively maintained international multi-institutional database, STAR (Stroke Thrombectomy and Aneurysm Registry), was reviewed for all patients aged 12-18 (adolescent) and 19-25 (young adult) years. Parameters were compared using chi-square and t-test analyses, and associations were interrogated using regression analyses., Results: Of 7192 patients in the registry, 41 (0.6%) satisfied all criteria, with a mean age of 19.7 ± 3.3 years. The majority were male (59%) and young adults (61%) versus adolescents (39%). The median prestroke modified Rankin Scale (mRS) score was 0 (range 0-2). Strokes were most common in the anterior circulation (88%), with the middle cerebral artery being the most common vessel (59%). The mean onset-to-groin puncture and groin puncture-to-reperfusion times were 327 ± 229 and 52 ± 42 minutes, respectively. The mean number of passes was 2.2 ± 1.2, with 61% of the cohort achieving successful reperfusion. There were only 3 (7%) cases of reocclusion. The median mRS score at 90 days was 2 (range 0-6). Between the adolescent and young adult subgroups, the median mRS score at last follow-up was statistically lower in the adolescent subgroup (1 vs 2, p = 0.03), and older age was significantly associated with a higher mRS at 90 days (coefficient 0.33, p < 0.01)., Conclusions: Although rare, MT for AIS in the AYA demographic is both safe and effective. Even within this relatively young demographic, age remains significantly associated with improved functional outcomes. The implication of age-dependent stroke outcomes after MT within the AYA demographic needs greater validation to develop effective age-specific protocols for long-term care across both pediatric and adult centers.

Importance: Limited data are available about the outcomes of mechanical thrombectomy (MT) for real-world patients with stroke presenting with a large core infarct., Objective: To investigate the safety and effectiveness of MT for patients with large vessel occlusion and an Alberta Stroke Program Early Computed Tomography Score (ASPECTS) of 2 to 5., Design, Setting, and Participants: This retrospective cohort study used data from the Stroke Thrombectomy and Aneurysm Registry (STAR), which combines the prospectively maintained databases of 28 thrombectomy-capable stroke centers in the US, Europe, and Asia. The study included 2345 patients presenting with an occlusion in the internal carotid artery or M1 segment of the middle cerebral artery from January 1, 2016, to December 31, 2020. Patients were followed up for 90 days after intervention. The ASPECTS is a 10-point scoring system based on the extent of early ischemic changes on the baseline noncontrasted computed tomography scan, with a score of 10 indicating normal and a score of 0 indicating ischemic changes in all of the regions included in the score., Exposure: All patients underwent MT in one of the included centers., Main Outcomes and Measures: A multivariable regression model was used to assess factors associated with a favorable 90-day outcome (modified Rankin Scale score of 0-2), including interaction terms between an ASPECTS of 2 to 5 and receiving MT in the extended window (6-24 hours from symptom onset)., Results: A total of 2345 patients who underwent MT were included (1175 women [50.1%]; median age, 72 years [IQR, 60-80 years]; 2132 patients [90.9%] had an ASPECTS of ≥6, and 213 patients [9.1%] had an ASPECTS of 2-5). At 90 days, 47 of the 213 patients (22.1%) with an ASPECTS of 2 to 5 had a modified Rankin Scale score of 0 to 2 (25.6% [45 of 176] of patients who underwent successful recanalization [modified Thrombolysis in Cerebral Ischemia score ≥2B] vs 5.4% [2 of 37] of patients who underwent unsuccessful recanalization; P = .007). Having a low ASPECTS (odds ratio, 0.60; 95% CI, 0.38-0.85; P = .002) and presenting in the extended window (odds ratio, 0.69; 95% CI, 0.55-0.88; P = .001) were associated with worse 90-day outcome after controlling for potential confounders, without significant interaction between these 2 factors (P = .64)., Conclusions and Relevance: In this cohort study, more than 1 in 5 patients presenting with an ASPECTS of 2 to 5 achieved 90-day functional independence after MT. A favorable outcome was nearly 5 times more likely for patients with low ASPECTS who had successful recanalization. The association of a low ASPECTS with 90-day outcomes did not differ for patients presenting in the early vs extended MT window.

Background and Purpose: Epidemiological studies have shown racial and ethnic minorities to have higher stroke risk and worse outcomes than non-Hispanic Whites. In this cohort study, we analyzed the STAR (Stroke Thrombectomy and Aneurysm Registry) database, a multi-institutional database of patients who underwent mechanical thrombectomy for acute large vessel occlusion stroke to determine the relationship between mechanical thrombectomy outcomes and race., Methods: Patients who underwent mechanical thrombectomy between January 2017 and May 2020 were analyzed. Data included baseline characteristics, vascular risk factors, complications, and long-term outcomes. Functional outcomes were assessed with respect to Hispanic status delineated as non-Hispanic White (NHW), non-Hispanic Black (NHB), or Hispanic patients. Multivariate analysis was performed to identify variables associated with unfavorable outcome or modified Rankin Scale ≥3 at 90 days., Results: Records of 2115 patients from the registry were analyzed. Median age of Hispanic patients undergoing mechanical thrombectomy was 60 years (72–84), compared with 63 years (54–74) for NHB, and 71 years (60–80) for NHW patients (P<0.001). Hispanic patients had a higher incidence of diabetes (41%; P<0.001) and hypertension (82%; P<0.001) compared with NHW and NHB patients. Median procedure time was shorter in Hispanics (36 minutes) compared to NHB (39 minutes) and NHW (44 minutes) patients (P<0.001). In multivariate analysis, Hispanic patients were less likely to have favorable outcome (odds ratio, 0.502 [95% CI, 0.263–0.959]), controlling for other significant predictors (age, admission National Institutes Health Stroke Scale, onset to groin time, number of attempts, procedure time)., Conclusions: Hispanic patients are less likely to have favorable outcome at 90 days following mechanical thrombectomy compared to NHW or NHB patients. Further prospective studies are required to validate our findings.

Background: Mechanical thrombectomy (MT) is the standard of care for the treatment of proximal anterior circulation large vessel occlusions. However, little is known about its efficacy and safety in the treatment of distal intracranial occlusions., Methods: This is a multicenter retrospective study of patients treated with MT at 15 comprehensive centers between January 2015 and December 2018. The study cohort was divided into 2 groups based on the location of occlusion (proximal vs. distal). Distal occlusion was defined as occlusion of M3 segment of the middle cerebral artery, any segment of the anterior cerebral artery, or any segment of the posterior cerebral artery. Only isolated distal occlusion was included. Good outcome was defined as 90-day modified Rankin scale score 0-2., Results: A total of 4710 patients were included in this study, of whom 189 (4%) had MT for distal occlusions. Compared with the proximal occlusion group, distal occlusion group had a higher rate of good outcome (45% vs. 36%; P = 0.03) and a lower rate of successful reperfusion (78% vs. 84%; P = 0.04). However, the differences did not retain significance in adjusted models. Otherwise there was no difference in the rate of hemorrhagic complications, mortality, or procedure-related complications between the 2 groups. Successful reperfusion, age, and admission stroke severity emerged as predictors of good functional outcome in the distal occlusion group., Conclusions: Thrombectomies of distal vessels achieve high rate of successful reperfusion with similar safety profile to those in more proximal locations., (Copyright © 2021 Elsevier Inc.

Purpose: The latest version of the Gamma Knife, the Icon, allows for immobilization with a mask in lieu of the traditional frame during stereotactic radiosurgery. There have been some concerns regarding extent of immobilization during single fraction frameless treatment and potential effect on outcomes. As such, we reviewed outcomes in patients with brain metastases treated in a single fraction using either a frame or mask on the Gamma Knife Icon at our institution., Methods and Materials: We reviewed the records of 95 patients with a total of 374 metastases treated between May 2019 and January 2021. Thirty-nine patients (41%) were treated using the Leksell frame with the remainder being immobilized with a mask. The median number of metastatic lesions was 2 (1-20). The median prescription dose was 20 Gy (11.5-24 Gy). Odds ratios were generated to identify predictors of mask use. Kaplan-Meier analysis was used to calculate survival, local failure, and distant failure rates. Cox regression was used to identify predictors of survival. Propensity matching was used to account for indication bias., Results: Of the 95 patients treated, 88 (93%) had follow-up with a median duration of 5 months (1-18). Frame utilization was more likely with 6 to 10 brain metastases. Median overall survival was not reached and was 70% and 60% at 6 and 12 months for the entire cohort, respectively. There was no significant difference in survival by immobilization method ( P  = .12). Six patients had local failure in 10 total lesions (3 patients in each group). After propensity matching the 12 month tumor local control was 96% and 85% for framed and frameless cases, respectively ( P  = .07)., Conclusions: Frameless mask-based stereotactic radiosurgery using the Gamma Knife Icon is feasible and maintains the excellent local control seen with the use of the headframe., (© 2021 The Authors.)

Background: Targeted anticancer therapies such as BCR-ABL tyrosine kinase inhibitors (TKIs) have improved outcomes for chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL). However, little is known about long-term risks of TKIs in children. Exposure-based survivorship guidelines do not include TKIs, thus surveillance practices may be variable., Methods: We retrospectively examined surveillance for cardiac and endocrine late effects in children receiving TKIs for Ph + leukemias, diagnosed at < 21 years between 2000 and 2018. Frequency of echocardiogram (ECHO), electrocardiogram (EKG), thyroid stimulating hormone (TSH), dual-energy x-ray absorptiometry (DXA), and bone age testing were abstracted. Descriptive statistics were stratified by leukemia type., Results: 66 patients (CML n = 44; Ph + ALL n = 22) met inclusion criteria. Among patients with CML, ≥1 evaluation was done: ECHO (50.0%), EKG (48.8%), TSH (43.9%), DXA (2.6%), bone age (7.4%). Among patients with Ph + ALL, ≥1 evaluation was done: ECHO (86.4%), EKG (68.2%), TSH (59.1%), DXA (63.6%), bone age (44.4%). Over a median 6.3 and 5.7 years of observation, respectively, 2% of patients with CML and 57% with Ph + ALL attended a survivorship clinic., Conclusions: Despite common exposure to TKIs in survivors of Ph + leukemias, patterns of surveillance for late effects differed in CML and Ph + ALL, with the latter receiving more surveillance likely due to concomitant chemotherapy exposures. Targeted therapies such as TKIs are revolutionizing cancer treatment, but surveillance for late effects and referral to survivorship clinics are variable despite the chronicity of exposure. Evidence based guidelines and longer follow-up are needed.

Organizational citizenship behaviors (OCBs) are commonly studied in the organizational and occupational health literature, yet, current OCB measures inherently assume individuals are performing these behaviors while physically at work. However, recent technological advances have afforded employees greater flexibility to engage in work-related behaviors at home, begging the question of whether OCBs are also being performed from home and their distinction from traditional OCBs. We provide evidence that OCBs performed while physically at work (OCB-W; i.e., traditional OCBs) are conceptually and empirically distinct from OCBs performed while physically at home (OCB-H). In Study 1 ( N = 292), we examine construct validity evidence for OCB-H with regard to its distinction from OCB-W and its unique nomological network. In Study 2, we further examine the distinction between OCB-H and OCB-W at the between- and within-person level using an experience sampling approach in a sample of 162 workers. Using results from multilevel confirmatory factor analysis, we show that between-person variance in OCB-H is considerably higher than for OCB-W, and that although OCB-H and OCB-W are strongly correlated at the between-person level, they are independent of one another at the within-person level. We also examine these two forms of OCB as parallel mediators of the relation between work engagement and work interfering with family. Results suggest OCB-H and OCB-W are indeed distinct in the strength of their relationships to work engagement and work interfering with family at between- and within-person levels.

Scholarly interest in workaholism has increased dramatically in recent years. This research has underscored the detrimental effects of workaholism for employees, their families, and the organizations that employ them. Despite drastic improvements in the quality of studies examining workaholism over the past several decades, researchers continue to almost exclusively rely on older measures of workaholism or new measures derived from these original measures. In the present study, we outline why a new measure is needed and propose a multidimensional conceptualization of workaholism that encompasses motivational, cognitive, emotional, and behavioral dimensions. We then develop and validate a new multidimensional measure of workaholism: the Multidimensional Workaholism Scale (MWS). Evidence from 5 samples representing individuals working in a wide variety of occupations and industries throughout the United States (total N = 1,252) provides support that (a) our proposed 4-factor structure replicates and fits better than alternative models; (b) the measure demonstrates high reliability and content validity; (c) the measure demonstrates evidence for convergent and discriminant validity with constructs in workaholism's nomological network; (d) the measure demonstrates incremental validity in the prediction of important outcomes over and above prior measures of workaholism; and (e) the different dimensions demonstrate incremental validity in the prediction of specific outcomes over and above other dimensions of the MWS. Overall, results from the present study suggest that the MWS is a reliable and valid measure that can advance a more nuanced approach to research and practice relating to workaholism.

Background and Purpose: Meningioma is a common type of benign tumor that can be managed in several ways, ranging from close observation, surgical resection, and various types of radiation. We present here results from a 10-year experience treating meningiomas with a hypofractionated approach., Materials and Methods: We reviewed the charts of 56 patients treated with stereotactic radiosurgery (SRS) or hypofractionated stereotactic radiotherapy (SRT) from 2008 to 2017. A total of 46 (82%) patients had WHO Grade 1 disease and 10 (18%) had Grade 2. Outcomes that were analyzed included local control rates and the rate and grade of any reported toxicity., Results: A total of 38 women and 18 men underwent SRS to a median dose of 15 Gy (n = 24) or hypofractionated SRT with a median dose of 25 Gy in five fractions (n = 34). Of the 56 patients, 22 had surgery before receiving treatment. The median follow-up was 36 (6-110) months. Local control at 2 and 5 years for all patients was 90% and 88%, respectively. Comparing fractionated to single-fraction treatment, there was improved local control with fractionation (91% vs 80% local control at 2 years, P  = .009). There was one episode of late radionecrosis on imaging with associated symptoms after single-fraction treatment and one patient requiring resection of meningioma related to worsening symptoms (and local recurrence) after five-fraction SRT., Conclusions: This study provides further evidence for high rates of local control and minimal toxicity using a hypofractionated SRT approach, with improvement in local control through use of hypofractionation., Competing Interests: Declaration of conflicting interests:The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: Large cell neuroendocrine carcinoma (LCNEC) of the lung is a rare pulmonary tumor, having similar natural history and management strategy as small cell lung cancer. Therefore, the management of brain metastases in these patients has mirrored that of SCLC through the use of whole brain radiation therapy (WBRT). We used the National Cancer Database (NCDB) to look at predictors of stereotactic radiosurgery (SRS) and any potential differences in outcomes for patients with brain metastases from LCNEC., Material and Methods: We queried the NCDB from 2004 to 2015 for patients with LCNEC of the lung with brain metastases that received brain radiation. Univariable and multivariable analyses were performed to identify factors predictive of SRS use and overall survival (OS). Propensity-adjusted Cox proportional hazard ratios for survival were used to account for indication bias., Results: Out of 9970 patients with LCNEC of the lung we identified 348 with brain metastases. Sixty-eight patients were treated with upfront SRS and 280 were treated with WBRT. Patients that were treated at an academic facility or received chemotherapy as part of upfront treatment were more likely to receive SRS. Univariable analysis revealed improved outcomes with SRS compared to WBRT, with a median OS of 11 months compared to 6 months, respectively (p = .007). Multivariable Cox regression with propensity score confirmed SRS to have improved survival (HR: 0.68, 95%CI: 0.51-0.91, p = .0093). Multivariable Cox regression with propensity score also identified younger age, receipt of chemotherapy, absence of extracranial disease and non-rural locations as additional predictors of improved OS., Conclusions: Treatment of brain metastases from LCNEC of the lung with SRS was associated with improved survival. For the appropriate patients, upfront treatment of limited brain metastases with SRS may be appropriate.

Purpose: Glioblastoma (GBM) carries a high propensity for in-field failure despite trimodality management. Past studies have failed to show outcome improvements with dose-escalation. Herein, we examined trends and outcomes associated with dose-escalation for GBM., Materials and Methods: The National Cancer Database was queried for GBM patients who underwent surgical resection and external-beam radiation with chemotherapy. Patients were excluded if doses were less than 59.4 Gy; dose-escalation referred to doses ≥66 Gy. Odds ratios identified predictors of dose-escalation. Univariable and multivariable Cox regressions determined potential predictors of overall survival (OS). Propensity-adjusted multivariable analysis better accounted for indication biases., Results: Of 33,991 patients, 1,223 patients received dose-escalation. Median dose in the escalation group was 70 Gy (range, 66 to 89.4 Gy). The use of dose-escalation decreased from 8% in 2004 to 2% in 2014. Predictors of escalated dose were African American race, lower comorbidity score, treatment at community centers, decreased income, and more remote treatment year. Median OS was 16.2 months and 15.8 months for the standard and dose-escalated cohorts, respectively (p = 0.35). On multivariable analysis, age >60 years, higher comorbidity score, treatment at community centers, decreased education, lower income, government insurance, Caucasian race, male gender, and more remote year of treatment predicted for worse OS. On propensity-adjusted multivariable analysis, age >60 years, distance from center >12 miles, decreased education, government insurance, and male gender predicted for worse outcome., Conclusion: Dose-escalated radiotherapy for GBM has decreased over time across the United States, in concordance with guidelines and the available evidence. Similarly, this large study did not discern survival improvements with dose-escalation.

Purpose: Childhood cancer survivors need regular, risk-adapted, long-term survivor care. This retrospective study describes the proportion of survivors seen for an initial survivor clinic visit within a large pediatric oncology program., Methods: Patients diagnosed with non-central nervous system childhood malignancies from 2007 to 2012 were followed from the time of survivor clinic eligibility (2 years following completion of therapy) through their initial survivor clinic visit or end of study. Demographic, cancer-related, and logistical factors related to clinic attendance were examined using Kaplan-Meier curves and Cox proportional regressions., Results: Eligible survivors were 53.0% male, 51.5% non-Hispanic white, and 30.9% survivors of leukemia. Among the 866 eligible survivors for this study, 610 (70.4%) completed their initial visit. After controlling for sex and time eligible, survivors who received surgery only (aHR 0.04 (0.02, 0.08)) or radiation only (0.24 (0.15, 0.39)) and who had Medicaid (0.77 (0.64, 0.92)) were significantly less likely to have an initial visit as were those of black or other/mixed race and those who lived > 25 mi from the clinic (p < 0.01). Survivors aged 6-11 years or 12-17 years at eligibility were significantly more likely to complete an initial visit as compared to those aged 2-5 years (1.55 (1.24, 1.93) and 1.44 (1.14, 1.83), respectively)., Conclusions: Nearly a third of survivors were not seen in a pediatric survivor clinic despite the importance of survivor care. These results identify populations at risk for not pursuing long-term survivorship care., Implications for Cancer Survivors: Failure to transition to pediatric survivor care may lead to lifelong non-engagement and incorrect perceptions about future health.

OBJECTIVE For a diagnosis of brain death (BD), ancillary testing is performed if patient factors prohibit a complete clinical examination and apnea test. The American Academy of Neurology (AAN) guidelines identify cerebral angiography (CA), cerebral scintigraphy, electroencephalography, and transcranial Doppler ultrasonography as accepted ancillary tests. CA is widely considered the gold standard of these, as it provides the most reliable assessment of intracranial blood flow. CT angiography (CTA) is a noninvasive and widely available study that is also capable of identifying absent or severely diminished intracranial blood flow, but it is not included among the AAN's accepted ancillary tests because of insufficient evidence demonstrating its reliability. The objective of this study was to assess the statistical performance of CTA in diagnosing BD, using clinical criteria alone or clinical criteria plus CA as the gold-standard comparisons. METHODS The authors prospectively enrolled 22 adult patients undergoing workup for BD. All patients had cranial imaging and clinical examination results consistent with BD. In patients who met the AAN clinical criteria for BD, the authors performed CA and CTA so that both tests could be compared with the gold-standard clinical criteria. In cases that required ancillary testing, CA was performed as a confirmatory study, and CTA was then performed to compare against clinical criteria plus CA. Radiographic data were evaluated by an independent neuroradiologist. Test characteristics for CTA were calculated. RESULTS Four patients could not complete the standard BD workup and were excluded from analysis. Of the remaining 18 patients, 16 met AAN criteria for BD, 9 of whom required ancillary testing with CA. Of the 16 patients, 2 who also required CA ancillary testing were found to have persistent intracranial flow and were not declared brain dead at that time. These patients also underwent CTA; the results were concordant with the CA results. Six patients who were diagnosed with BD on the basis of clinical criteria alone also underwent CA, with 100% sensitivity. For all 18 patients included in the study, CTA had a sensitivity of 75%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 33%. CONCLUSIONS Clinical examination with or without CA remains the gold standard in BD testing. Studies assessing the statistical performance of CTA in BD testing should compare CTA to these gold standards. The statistical performance of CTA in BD testing is comparable to several of the nationally accepted ancillary tests. These data add to the growing medical literature supporting the use of CTA as a reliable ancillary test in BD testing.

Background: Moyamoya angiopathy most often manifests in patients in the second and third decades of life. Although uncommon, it can also manifest later in life. We present our results in patients >50 years old with moyamoya angiopathy who were treated with surgical revascularization via either direct bypass or indirect bypass (encephaloduroarteriosynangiosis)., Methods: A retrospective review was conducted to identify patients with moyamoya disease who were treated with surgical revascularization at our institution between 2002 and 2015. Outcomes and complications were analyzed., Results: We identified 33 patients with moyamoya angiopathy >50 years old (mean age 59.0 years ± 7.6) who were treated with surgical revascularization of 45 affected hemispheres. Of the affected hemispheres, 27 (60%) were treated with indirect bypasses and 18 (40%) were treated with direct bypasses. Neurologic complications occurred in 4 (12%) patients. The mean length of follow-up was 18.7 months ± 18.6; 4 patients were lost to follow-up. At last follow-up, 11 of 18 (61%) direct bypasses were patent. Treatment failed in 5 of 45 (11%) treated hemispheres (stroke in 2 and persistent transient ischemic attacks in 3). In terms of functional outcome at last follow-up, 16 of 29 (55%) patients were the same as before surgery, 10 (35%) were better, and 3 (10%) were worse (including 1 death)., Conclusions: Although uncommon, moyamoya angiopathy can manifest in older adults. Surgical revascularization is a reasonable treatment option with good functional outcomes and an acceptable complication rate., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Study Question: Can host fertility be rescued by grafting of a fragment of a healthy ovary soon after chemotherapy?, Summary Answer: We found that grafting a green fluorescent protein (GFP)-positive fragment from a healthy isogenic ovary to the left ovary of a chemo-treated host rescued function and fertility of the grafted host ovary, and resulted in the production of host-derived offspring as late as the sixth litter after chemotherapy (CTx) treatment, whereas none of the ungrafted controls produced a second litter., What Is Known Already: In women and girls undergoing chemotherapy, infertility and premature ovarian failure are frequent outcomes. There are accumulating reports of improved endocrine function after autotransplantation of an ovarian fragment, raising the possibility that the transplant is beneficial to the endogenous ovary., Study Design, Size, Duration: We first established a CTx treatment regimen that resulted in the permanent loss of fertility in 100% of female mice of the FVB inbred strain. We grafted an isogenic ovary fragment from a healthy female homozygous for a GFP transgene to the left ovary of 100 CTx-treated hosts, and compared fertility to 39 ungrafted controls in 6 months of continuous matings, using GFP to distinguish offspring derived from the graft, and those derived from the host., Participants/materials, Setting, Methods: Immunofluoresece and western blot analysis of 39 treated ovaries during and 15 days after CTx treatment revealed elevated apoptosis, rapid loss of granulosa cells and an increased recruitment of growing follicles. Using immunofluorescence and confocal imaging, we tracked the outcome of the grafted tissue over 4 months and its effect on the adjacent and contralateral ovary of the host., Main Results and the Role of Chance: Fifty-three percent of grafted females produced a second litter whereas none of the ungrafted females produced a second litter. The likelihood that this could occur by chance is very low (P < 0.0001)., Limitations, Reasons for Caution: These results are shown only in mice, and whether or how they might apply to chemotherapy patients subjected to different CTx regimens is not yet clear., Wider Implications of the Findings: Our experiments prove that rescue of a chemo-treated ovary is possible, and establish a system to investigate the mechanism of rescue and to identify the factors responsible with the long-term goal of developing therapies for preservation of ovarian endocrine function and fertility in women undergoing chemotherapy., Large Scale Data: No large datasets were produced., Study Funding/competing Interests: Duke University Medical Center Chancellor's Discovery Grant to BC; ESJ was supported by an NRSA 5F31CA165545; SK was supported by NIH RO1 GM08033; RWT was supported by the Duke University School of Medicine Ovarian Cancer Research Fellowship; XBM was supported by CONICYT.

Object: Subarachnoid hemorrhage (SAH) from ruptured posterior inferior cerebellar artery (PICA) aneurysms is uncommon, and long-term outcome data for patients who have suffered such hemorrhages is lacking. This study investigated in-hospital and long-term clinical data from a prospective cohort of patients with SAH from ruptured PICA aneurysms enrolled in a randomized trial; their outcomes were compared with those of SAH patients who were treated for other types of ruptured intracranial aneurysms. The authors hypothesize that PICA patients fare worse than those with aneurysms in other locations and this difference is related to the high rate of lower cranial nerve dysfunction in PICA patients., Methods: The authors analyzed data for 472 patients enrolled in the Barrow Ruptured Aneurysm Trial (BRAT) and retrospectively reviewed vasospasm data not collected prospectively. In the initial cohort, 57 patients were considered angiographically negative for aneurysmal SAH source and did not receive treatment for aneurysms, leaving 415 patients with aneurysmal SAH., Results: Of 415 patients with aneurysmal SAH, 22 (5.3%) harbored a ruptured PICA aneurysm. Eight of them had dissecting/fusiform-type aneurysms while 14 had saccular-type aneurysms. Nineteen PICA patients were treated with clipping (1 crossover from coiling), 2 were treated with coiling, and 1 died before treatment. When comparing PICA patients to all other aneurysm patients in the study cohort, there were no statistically significant differences in age (mean 57.6 ± 11.8 vs 53.9 ± 11.8 years, p = 0.17), Hunt and Hess grade median III [IQR II-IV] vs III [IQR II-III], p = 0.15), Fisher grade median 3 [IQR 3-3] vs 3 [IQR 3-3], p = 0.53), aneurysm size (mean 6.2 ± 3.0 vs 6.7 ± 4.0 mm, p = 0.55), radiographic vasospasm (53% vs 50%, p = 0.88), or clinical vasospasm (12% vs 23%, p = 0.38). PICA patients were more likely to have a fusiform aneurysm (36% vs 12%, p = 0.004) and had a higher incidence of lower cranial nerve dysfunction and higher rate of tracheostomy/percutaneous endoscopic gastrostomy placement compared with non-PICA patients (50% vs 16%, p < 0.001). PICA patients had a significantly higher incidence of poor outcome at discharge (91% vs 67%, p = 0.017), 1-year follow-up (63% vs 29%, p = 0.002), and 3-year follow-up (63% vs 32%, p = 0.006)., Conclusions: Patients with ruptured PICA aneurysms had a similar rate of radiographic vasospasm, equivalent admission Fisher grade and Hunt and Hess scores, but poorer clinical outcomes at discharge and at 1- and 3-year follow-up when compared with the rest of the BRAT SAH patients with ruptured aneurysms. The PICA's location at the medulla and the resultant high rate of lower cranial nerve dysfunction may play a role in the poor outcome for these patients. Furthermore, PICA aneurysms were more likely to be fusiform than saccular, compared with non-PICA aneurysms; the complex nature of these aneurysms may also contribute to their poorer outcome.

Concussion is an important cause of morbidity in young student athletes. The prevention, accurate diagnosis, and prompt management of concussions require that players, parents, coaches, and medical personnel are accurately educated on current concussion data and guidelines. All states have laws that mandate concussion education for high school athletes. There is currently no uniform educational program to disseminate information to student athletes regarding concussions. This article highlights a few nationally recognized educational programs that aim to accurately and effectively inform all members of the athletic, academic, and medical communities about the importance and urgency of concussion.

Objective: Surgical freedom and the angle of attack influence approach selection for open cranial base approaches, but these concepts have not been well studied in minimal-access endoscopic approaches. We therefore developed a methodology to study surgical freedom and angle of attack in two endoscopic transmaxillary transpterygoid approaches, the endonasal ipsilateral uninostril medial maxillotomy and the sublabial Caldwell-Luc anterior maxillotomy., Methods: Dissections were performed bilaterally in three formalin-fixed cadaver heads (six sides). For each approach, three progressively lateral and posterior anatomic targets were identified. Utilizing frameless stereotaxy, surgical freedom using the vector cross-product method was calculated for both approaches for each target. The mean and maximum possible angles of attack were calculated in the axial and sagittal planes., Results: Compared to the endoscopic endonasal-transmaxillary approach, the endoscopic Caldwell-Luc approach offered significantly greater surgical freedom to the genu of the internal carotid artery (P=0.02), foramen rotundum (P=0.03), and foramen ovale (P=0.03). Mean and maximum possible angles of attack were also significantly different between the two approaches for each target. The Caldwell-Luc approach offered a more bottom-up approach in the sagittal plane and a more head-on approach in the axial plane to each target (P<0.05)., Conclusions: We have successfully developed a model for comparing endoscopic skull base approaches. Both the endonasal medial maxillotomy approach and Caldwell-Luc approach provided endoscopic access to each target. However, the sublabial Caldwell-Luc approach offered greater surgical freedom and a more head-on approach than the endonasal medial maxillotomy. These differences in surgical freedom and angles of attack may be useful to consider when planning minimal-access approaches., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Object: Cerebral vasospasm following subarachnoid hemorrhage (SAH) causes significant morbidity in a delayed fashion. The authors recently published a new scale that grades the maximum thickness of SAH on axial CT and is predictive of vasospasm incidence. In this study, the authors further investigate whether different aneurysm locations result in different SAH clot burdens and whether any concurrent differences in ruptured aneurysm location and maximum SAH clot burden affect vasospasm incidence., Methods: Two hundred fifty patients who were part of a prospective randomized controlled trial were reviewed. Most outcome and demographic variables were included as part of the prospective randomized controlled trial. Additional variables were also collected at a later time, including vasospasm data and maximum clot thickness., Results: Aneurysms were categorized into 1 of 6 groups: intradural internal carotid artery aneurysms, vertebral artery (VA) aneurysms (including the posterior inferior cerebellar artery), basilar trunk or basilar apex aneurysms, middle cerebral artery aneurysms, pericallosal aneurysms, and anterior communicating artery aneurysms. Twenty-nine patients with nonaneurysmal SAH were excluded. Patients with pericallosal aneurysms had the least average maximum clot burden (5.3 mm), compared with 6.4 mm for the group overall, but had the highest rate of symptomatic vasospasm (56% vs 22% overall, OR 4.9, RR 2.7, p = 0.026). Symptomatic vasospasm occurrence was tallied in patients with clinical deterioration attributable to delayed cerebral ischemia. There were no significant differences in maximum clot thickness between aneurysm sites. Middle cerebral artery aneurysms resulted in the thickest mean maximum clot (7.1 mm) but rates of symptomatic and radiographic vasospasm in this group were statistically no different compared with the overall group. Vertebral artery aneurysms had the worst 1-year modified Rankin scale (mRS) scores (3.0 vs 1.9 overall, respectively; p = 0.0249). A 1-year mRS score of 0-2 (good outcome) was found in 72% of patients overall, but in only 50% of those with pericallosal and VA aneurysms, and in 56% of those with basilar artery aneurysms (p = 0.0044). Patients with stroke from vasospasm had higher mean clot thickness (9.71 vs 6.15 mm, p = 0.004)., Conclusions: The location of a ruptured aneurysm minimally affects the maximum thickness of the SAH clot but is predictive of symptomatic vasospasm or clinical deterioration from delayed cerebral ischemia in pericallosal aneurysms. The worst 1-year mRS outcomes in this cohort of patients were noted in those with posterior circulation aneurysms or pericallosal artery aneurysms. Patients experiencing stroke had higher mean clot burden.

We compared the histopathological features of the outer membrane of a chronic subdural hematoma (CSH) with its clinico-radiological presentation in patients. One hundred and fifty-six patients undergoing surgery for CSH were prospectively included in this study. Histopathological specimens of the outer neomembrane obtained intraoperatively were studied. Histological features were classified into four types and analyzed in relation to the Glasgow Coma Scale (GCS) score at presentation and radiological features. On histopathological examination, there were no cases of type I, 42.3% cases of type II and 34.6% cases of type III and 23.1% cases of types IV CSH neomembranes. Patients presenting with a GCS <13 exclusively had type II neomembranes. Increased radiodensity and thickness of the hematoma correlated with type IV neomembranes. This study may serve as an incentive to investigate the histopathology of CSH membranes in predicting outcomes and the recurrence of subdural hemorrhage after drainage surgery., (Copyright © 2013 Elsevier Ltd.

Objective: To report a single case of malignant transformation of a vestibular schwannoma after radiosurgery and review the growing body of literature describing patients with malignant transformation of primary benign tumors after radiosurgery, including vestibular schwannoma., Methods: A 46-year-old woman presented with right facial paresthesias and imaging consistent with a right-sided vestibular schwannoma (volume approximately 18.5 cm(3))., Results: The patient underwent subtotal resection followed by Gamma Knife radiosurgery (GKRS) 6 months after surgery. Initial histology showed a benign vestibular schwannoma with an MIB-1 labeling index of 5.7%. At 43 months after GKRS, the patient underwent repeat subtotal resection of a benign vestibular schwannoma (MIB-1 labeling index 7.4%). At 59 months after GKRS, she underwent a third resection, and histology showed frank malignant transformation (MIB-1 labeling index 33.8%)., Conclusions: Malignant vestibular nerve tumors are extremely rare; only 18 cases have been reported in the literature. Our patient is the sixth pathologically confirmed case of malignant transformation after radiosurgery, supporting the contention that radiosurgery itself may play a causative role in transformation. In a histologically benign lesion, the presence of an elevated MIB-1 labeling index may predispose toward malignant transformation in the setting of adjuvant radiosurgery., (Copyright © 2013 Elsevier Inc.

Background and Importance: Purely intraorbital arteriovenous fistulas (AVFs), which are rare vascular malformations that clinically mimic carotid-cavernous fistulas (CCFs), involve a fistula from the ophthalmic artery to 1 of the draining ophthalmic veins. We describe a case of an intraorbital AVF treated with transvenous endovascular coil embolization via the inferior petrosal sinus (IPS) route and review the literature on this rare entity., Clinical Presentation: An 81-year-old woman sought treatment after 7 days of progressive left-sided visual acuity loss, chemosis, and lateral rectus palsy. Magnetic resonance imaging demonstrated dilated vascularity in the left orbit raising suspicions for a CCF. Cerebral angiography showed a purely intraorbital AVF with a fistula between the left ophthalmic artery and superior ophthalmic vein (SOV). Transvenous selective catheterization of the fistula was performed by successfully navigating the ipsilateral IPS to the cavernous sinus and SOV. The fistula was then embolized using detachable coils. The patient was discharged the next day. Three weeks after embolization, her ocular symptoms and findings had resolved., Conclusion: Intraorbital AVFs are a rare type of AVF that can be treated by direct surgical ligation, transarterial embolization, or transvenous embolization. We successfully navigated the IPS, which is frequently stenotic or occluded secondary to chronically increased fistulous drainage, and utilized this route to embolize the fistula with detachable coils.

Background: Aneurysms of the posterior inferior cerebellar artery (PICA) are rare, comprising 0.5% to 3% of intracranial aneurysms. Because their anatomic location relative to the PICA origin is variable, several endovascular techniques are used in their management., Objective: To evaluate and discuss endovascular techniques for the treatment of PICA aneurysms., Methods: We analyzed our prospectively maintained database to identify PICA aneurysms treated over a 12-year period from 1999 to 2011., Results: Twenty patients were assessed angiographically for endovascular treatment. Treatment was successfully performed in 17, but 3 were deemed unsuitable and were referred for surgery. Patients ranged in age from 15 to 82 years (mean, 60.5); 85% (17/20) were women. Thirteen (65%) presented with subarachnoid hemorrhage, and 3 (15%) had been previously treated surgically. Although the aneurysms were located at the PICA origin in 13 (65%), their involvement with the PICA and vertebral artery was variable. Some arose distinctly from the origin, and others incorporated the PICA itself. Five patients were treated for distal PICA aneurysms. Treatment techniques included direct coiling, vertebral artery balloon remodeling with coiling, PICA balloon remodeling with coiling, and parent vessel sacrifice of PICA with either coiling or glue embolization. Complete occlusion was initially achieved in 11 of 17 patients. Of the 6 remaining patients, 3 improved to complete occlusion at follow-up, 2 underwent re-treatment, and 1 remained stable. No patient experienced posttreatment hemorrhage., Conclusion: A variety of endovascular techniques are required for the management of PICA aneurysms. Specific techniques vary according to the location of the aneurysm in relation to the PICA origin, distal course of the artery, and the vertebral artery., Abbreviations: BRAT, Barrow Ruptured Aneurysm TrialmRS, modified Rankin scorenBCA, n-butyl cyanoacrylatePICA, posterior inferior cerebellar arterySAH, subarachnoid hemorrhageVA, vertebral artery.
