RESUMEN
BACKGROUND: While mechanical thrombectomy (MT) is proven to be lifesaving and disability sparing, there remains a disparity in its access in low- to middle-income countries. We hypothesized that team-based MT workshops would improve MT knowledge and skills. METHODS: We designed a 22-hour MT workshop, conducted as 2 identical events: in English (Jamaica, January 2022) and in Spanish (Dominican Republic, May 2022). The workshops included participating neurointerventional teams (practicing neurointerventionalists, neurointerventional nurses, and technicians) focused on acute stroke due to large vessel occlusion. The course faculty led didactic and hands-on components, covering topics from case selection and postoperative management to device technology and MT surgical techniques. Attendees were evaluated on stroke knowledge and MT skills before and after the course using a multiple choice exam and simulated procedures utilizing flow models under fluoroscopy, respectively. Press conferences for public education with invited government officials were included to raise stroke awareness. RESULTS: Twenty-two physicians and their teams from 8 countries across the Caribbean completed the didactic and hands-on training. Overall test scores (n=18) improved from 67% to 85% (P<0.002). Precourse and postcourse hands-on assessments demonstrated reduced time to completion from 36.5 to 21.1 minutes (P<0.001). All teams showed an improvement in measures of good MT techniques, with 39% improvement in complete reperfusion. Eight teams achieved a Thrombolysis in Cerebral Infarction score of 3 on pre-course versus 15 of 18 teams on post-course. There was a significant reduction in total potentially dangerous maneuvers (70% pre versus 20% post; P<0.002). Universally, the workshop was rated as satisfactory and likely to change practice in 93% Dominican Republic and 75% Jamaica. CONCLUSIONS: A team-based hands-on simulation approach to MT training is novel, feasible, and effective in improving procedural skills. Participants viewed these workshops as practice-changing and instrumental in creating a pathway for increasing access to MT in low- to middle-income countries.

OBJECTIVES: We explore patient-reported behaviors and activities within 30-days post-stroke hospitalization and their role in reducing death or readmissions within 90-days post-stroke. METHODS: We constructed the adequate transitions of care (ATOC) composite score, measuring patient-reported participation in eligible behaviors and activities (diet modification, weekly exercise, follow-up medical appointment attendance, medication adherence, therapy use, and toxic habit cessation) within 30 days post-stroke hospital discharge. We analyzed ATOC scores in ischemic and intracerebral hemorrhage stroke patients discharged from the hospital to home or rehabilitation facilities and enrolled in the NIH-funded Transitions of Care Stroke Disparities Study (TCSD-S). We utilized Cox regression analysis, with the progressive adjustment for sociodemographic variables, social determinants of health, and stroke risk factors, to determine the associations between ATOC score within 30-days and death or readmission within 90-days post-stroke. RESULTS: In our sample of 1239 stroke patients (mean age 64 +/- 14, 58 % male, 22 % Hispanic, 22 % Black, 52 % White, 76 % discharged home), 13 % experienced a readmission or death within 90 days (3 deaths, 160 readmissions, 3 readmissions with subsequent death). Seventy percent of participants accomplished a ≥75 % ATOC score. A 25 % increase in ATOC was associated with a respective 20 % (95 % CI 3-33 %) reduced risk of death or readmission within 90-days. CONCLUSION: ATOC represents modifiable behaviors and activities within 30-days post-stroke that are associated with reduced risk of death or readmission within 90-days post-stroke. The ATOC score should be validated in other populations, but it can serve as a tool for improving transitions of stroke care initiatives and interventions.
RESUMEN
BACKGROUND: Our objective is to describe adoption of the posthospitalization behaviors associated with successful transition of care and related baseline characteristics. METHODS: This study includes 550 participants in the Transition of Care Stroke Disparities Study, a prospective observational cohort derived from the Florida Stroke Registry. Participants had an ischemic stroke (2018-2021), discharged home or to rehabilitation, with modified Rankin Scale score=0-3 (44% women, 24% Black, 48% White, 26% Hispanic, 35% foreign-born). We collected baseline sociodemographic and clinical characteristics. A structured telephone interview at 30-day postdischarge evaluated outcomes including medication adherence, medical appointment attendance, outpatient therapy, exercise, diet modification, toxic habit cessation, and a calculated composite adequate transition of care measure. Multivariable analyses assessed the association of baseline characteristics with 30-day behaviors. RESULTS: At 30 days, medication adherence was achieved by 89%, medical appointments by 82%, outpatient therapy by 76%, exercise by 71%, diet modification by 68%, toxic habit cessation by 35%, and adequate transition of care measure by 67%. Successful adequate transition of care participants were more likely to be used full-time (42% versus 31%, P=0.02), live with a spouse (60% versus 47%, P=0.01), feel close to ≥3 individuals (84% versus 71%, P<0.01), have history of dyslipidemia (45 versus 34%, P=0.02), have thrombectomy (15% versus 8%, P=0.02), but less likely to have a history of smoking (17% versus 32%, P<0.001), coronary artery disease (14% versus 21%, P=0.04), and heart failure (3% versus 11%, P<0.01). Multivariable logistic regression analyses revealed that multiple socio-economic factors and prestroke comorbid diseases predicted fulfillment of transition of care measures. There was no difference in outcomes during the Covid-19 pandemic (2020-2021) compared with prepandemic years (2018-2019). CONCLUSIONS: One in 3 patients did not attain adequate 30-day transition of care behaviors. Their achievement varied substantially among different measures and was influenced by multiple socioeconomic and clinical factors. Interventions aimed at facilitating transition of care from hospital after stroke are needed. REGISTRATION: URL: https://clinicaltrials.gov/; Unique identifier: NCT03452813.

BACKGROUND: The impact of time to treatment on outcomes of endovascular thrombectomy (EVT) especially in patients presenting after 6 hours from symptom onset is not well characterized. We studied the differences in characteristics and treatment timelines of EVT-treated patients participating in the Florida Stroke Registry and aimed to characterize the extent to which time impacts EVT outcomes in the early and late time windows. METHODS: Prospectively collected data from Get With the Guidelines-Stroke hospitals participating in the Florida Stroke Registry from January 2010 to April 2020 were reviewed. Participants were EVT patients with onset-to-puncture time (OTP) of ≤24 hours and categorized into early window treated (OTP ≤6 hours) and late window treated (OTP >6 and ≤24 hours). Association between OTP and favorable discharge outcomes (independent ambulation, discharge home and to acute rehabilitation facility) as well as symptomatic intracerebral hemorrhage and in-hospital mortality were examined using multilevel-multivariable analysis with generalized estimating equations. RESULTS: Among 8002 EVT patients (50.9% women; median age [±SD], 71.5 [±14.5] years; 61.7% White, 17.5% Black, and 21% Hispanic), 34.2% were treated in the late time window. Among all EVT patients, 32.4% were discharged home, 23.5% to rehabilitation facility, 33.7% ambulated independently at discharge, 5.1% had symptomatic intracerebral hemorrhage, and 9.2% died. As compared with the early window, treatment in the late window was associated with lower odds of independent ambulation (odds ratio [OR], 0.78 [0.67-0.90]) and discharge home (OR, 0.71 [0.63-0.80]). For every 60-minute increase in OTP, the odds of independent ambulation reduced by 8% (OR, 0.92 [0.87-0.97]; P<0.001) and 1% (OR, 0.99 [0.97-1.02]; P=0.5) and the odds of discharged home reduced by 10% (OR, 0.90 [0.87-0.93]; P<0.001) and 2% (OR, 0.98 [0.97-1.00]; P=0.11) in the early and late windows, respectively. CONCLUSIONS: In routine practice, just over one-third of EVT-treated patients independently ambulate at discharge and only half are discharged to home/rehabilitation facility. Increased time from symptom onset to treatment is significantly associated with lower chance of independent ambulation and ability to be discharged home after EVT in the early time window.

BACKGROUND: Short-term dual antiplatelet therapy (DAPT) reduces early stroke recurrence after mild noncardioembolic ischemic stroke (NCIS). We aim to evaluate temporal trends and determinants of DAPT prescription after mild NCIS in the Florida Stroke Registry, a statewide registry across Get With The Guidelines-Stroke participating hospitals. METHODS: In this cross-sectional analysis of a cohort study, we included patients with mild NCIS (National Institutes of Health Stroke Scale score ≤3) who were potentially eligible for DAPT across 168 Florida Stroke Registry participating hospitals between January 2010 and September 2022. Using antiplatelet prescription as the dependent variable (DAPT versus single antiplatelet therapy), we fit logistic regression models adjusted for patient-related factors, hospital-related factors, clinical presentation, vascular risk factors, and ischemic stroke subtype, to obtain adjusted odds ratios (aORs) with 95% CIs. RESULTS: From 283â 264 Florida Stroke Registry ischemic stroke patients during the study period, 109â 655 NCIS were considered eligible. Among these, 37â 058 patients with National Institutes of Health Stroke Scale score >3 were excluded, resulting in a sample of 72â 597 mild NCIS (mean age 68±14 years; female 47.3%). Overall, 24â 693 (34.0%) patients with mild NCIS were discharged on DAPT and 47â 904 (66.0%) on single antiplatelet therapy. DAPT prescription increased from 25.7% in 2010 to 52.8% in 2022 (ß/year 2.5% [95% CI, 1.5%-3.4%]). Factors associated with DAPT prescription were premorbid antiplatelet therapy (aOR, 4.66 [95% CI, 2.20-9.88]), large-artery atherosclerosis (aOR, 1.68 [95% CI, 1.43-1.97]), diabetes (aOR, 1.29 [95% CI, 1.13-1.47]), and hyperlipidemia (aOR, 1.24 [95% CI, 1.10-1.39]), whereas female sex (aOR, 0.83 [95% CI, 0.75-0.93]), being non-Hispanic Black patients (compared with non-Hispanic White patients; aOR, 0.78 [95% CI, 0.68-0.90]), admission to a Thrombectomy-capable Stroke Center (compared with Comprehensive Stroke Center; aOR, 0.78 [95% CI, 0.66-0.92]), time-to-presentation 1 to 7 days from last seen well (compared with <24 h; aOR, 0.86 [95% CI, 0.76-0.96]), and small-vessel disease stroke (aOR, 0.81 [95% CI, 0.72-0.94]) were associated with not receiving DAPT at discharge. CONCLUSIONS: Despite a temporal trend increase in DAPT prescription after mild NCIS, we found substantial underutilization of evidence-based DAPT associated with significant disparities in stroke care.

OBJECTIVE: The Transitions of Stroke Care Disparities Study (TCSD-S) is an observational study designed to determine race-ethnic and sex disparities in post-hospital discharge transitions of stroke care and stroke outcomes and to develop hospital-level initiatives to reduce these disparities to improve stroke outcomes. MATERIALS AND METHODS: Here, we present the study rationale, describe the methodology, report preliminary outcomes, and discuss a critical need for the development, implementation, and dissemination of interventions for successful post-hospital transition of stroke care. The preliminary outcomes describe the demographic, stroke risk factor, socioeconomic, and acute care characteristics of eligible participants by race-ethnicity and sex. We also report on all-cause and vascular-related death, readmissions, and hospital/emergency room representations at 30- and 90-days after hospital discharge. RESULTS: The preliminary sample included data from 1048 ischemic stroke and intracerebral hemorrhage discharged from 10 comprehensive stroke centers across the state of Florida. The overall sample was 45% female, 22% Non-Hispanic Black and 21% Hispanic participants, with an average age of 64 ± 14 years. All cause death, readmissions, or hospital/emergency room representations are 10% and 19% at 30 and 90 days, respectively. One in 5 outcomes was vascular-related. CONCLUSIONS: This study highlights the transition from stroke hospitalization as an area in need for considerable improvement in systems of care for stroke patients discharged from hospital. Results from our preliminary analysis highlight the importance of investigating race-ethnic and sex differences in post-stroke outcomes.

Patients with premorbid disability or dementia have generally been excluded from randomized controlled trials of reperfusion therapies such as thrombolysis and endovascular therapy for acute ischemic stroke. Consequently, stroke physicians face treatment dilemmas in caring for such patients. In this scientific statement, we review the literature on acute ischemic stroke in patients with premorbid disability or dementia and propose principles to guide clinicians, clinician-scientists, and policymakers on the use of acute stroke therapies in these populations. Recent clinical-epidemiological studies have demonstrated challenges in our concept and measurement of premorbid disability or dementia while highlighting the significant proportion of the general stroke population that falls under this umbrella, risking exclusion from therapies. Such studies have also helped clarify the adverse long-term clinical and health economic consequences with each increment of additional poststroke disability in these patients, underscoring the importance of finding strategies to mitigate such additional disability. Several observational studies, both case series and registry-based studies, have helped demonstrate the comparable safety of endovascular therapy in patients with premorbid disability or dementia and in those without, complementing similar data on thrombolysis. These data also suggest that such patients have a substantial potential to retain their prestroke level of disability when treated, despite their generally worse prognosis overall, although this remains to be validated in higher-quality registries and clinical trials. By pairing pragmatic and transparent decision-making in clinical practice with an active pursuit of high-quality research, we can work toward a more inclusive paradigm of patient-centered care for this often-neglected patient population.

There are many unknowns when it comes to the role of sex in the pathophysiology and management of acute ischemic stroke. This is particularly true for endovascular treatment (EVT). It has only recently been established as standard of care; therefore, data are even more scarce and conflicting compared with other areas of acute stroke. Assessing the role of sex and gender as isolated variables is challenging because they are closely intertwined with each other, as well as with patients' cultural, ethnic, and social backgrounds. Nevertheless, a better understanding of sex- and gender-related differences in EVT is important to develop strategies that can ultimately improve individualized outcome for both men and women. Disregarding patient sex and gender and pursuing a one-size-fits-all strategy may lead to suboptimal or even harmful treatment practices. This scientific statement is meant to outline knowledge gaps and unmet needs for future research on the role of sex and gender in EVT for acute ischemic stroke. It also provides a pragmatic road map for researchers who aim to investigate sex- and gender-related differences in EVT and for clinicians who wish to improve clinical care of their patients undergoing EVT by accounting for sex- and gender-specific factors. Although most EVT studies, including those that form the basis of this scientific statement, report patient sex rather than gender, open questions on gender-specific EVT differences are also discussed.

BACKGROUND: Global access to acute stroke treatment is variable worldwide, with notable gaps in low and middle-income countries (LMIC), especially in rural areas. Ensuring a standardized method for pinpointing the existing regional coverage and proposing potential sites for new stroke centers is essential to change this scenario. AIMS: To create and apply computational strategies (CSs) to determine optimal locations for new acute stroke centers (ASCs), with a pilot application in nine Latin American regions/countries. METHODS: Hospitals treating acute ischemic stroke (AIS) with intravenous thrombolysis (IVT) and meeting the minimum infrastructure requirements per structured protocols were categorized as ASCs. Hospitals with emergency departments, noncontrast computed tomography (NCCT) scanners, and 24/7 laboratories were identified as potential acute stroke centers (PASCs). Hospital geolocation data were collected and mapped using the OpenStreetMap data set. A 45-min drive radius was considered the ideal coverage area for each hospital based on the drive speeds from the OpenRouteService database. Population data, including demographic density, were obtained from the Kontur Population data sets. The proposed CS assessed the population covered by ASCs and proposed new ASCs or artificial points (APs) settled in densely populated areas to achieve a target population coverage (TPC) of 95%. RESULTS: The observed coverage in the region presented significant disparities, ranging from 0% in the Bahamas to 73.92% in Trinidad and Tobago. No country/region reached the 95% TPC using only its current ASCs or PASCs, leading to the proposal of APs. For example, in Rio Grande do Sul, Brazil, the introduction of 132 new centers was suggested. Furthermore, it was observed that most ASCs were in major urban hubs or university hospitals, leaving rural areas largely underserved. CONCLUSIONS: The MAPSTROKE project has the potential to provide a systematic approach to identify areas with limited access to stroke centers and propose solutions for increasing access to AIS treatment.

Stroke is the leading cause of death and adult-onset disability in the Caribbean region. Despite the tremendous advances in acute stroke care in the past 25 years, treatment in the Caribbean lags stroke standards of care. Mission Thrombectomy 2020+ (MT2020+) is a metrics based global campaign focused on increasing access to organized stroke care and mechanical thrombectomy. We conducted two consecutive online surveys across the MT2020+ Caribbean Region assessing access to thrombolytics, mechanical thrombectomy and stroke centers. The first survey - Mechanical Thrombectomy Access-Caribbean sub-study, allowed a comparison between global services and those in the MT2020+ Caribbean region. This survey provided a snapshot of the current state of stroke centers worldwide and confirmed lower available stroke resources in the MT2020+ Caribbean Region which has one certified stroke center, and 9 mechanical thrombectomy capable centers. The second survey - MT2020+ Caribbean Region infrastructure survey - was designed to determine the availability of stroke resources that are key components of stroke care in participating hospitals. Key infrastructural components such as 24/7 computerized tomographic scanners, access to thrombolytic therapy and access to mechanical thrombectomy capable centers were scarce. There were low volumes of mechanical thrombectomy performed in the Caribbean compared to other countries around the world. Limited resources and inadequate stroke infrastructure remains a major challenge in the Caribbean. We advocate for governmental support and investment, public and private partnerships and legislation to increase access and availability to acute stroke treatments to allow for equal access to care for all Caribbean citizens.

BACKGROUND: Guideline-based hypertension management is integral to the prevention of stroke. We examine trends in antihypertensive medications prescribed after stroke and assess how well a prescriber's blood pressure (BP) medication choice adheres to clinical practice guidelines (BP-guideline adherence). METHODS AND RESULTS: The FSR (Florida Stroke Registry) uses statewide data prospectively collected for all acute stroke admissions. Based on established guidelines, we defined optimal BP-guideline adherence using the following hierarchy of rules: (1) use of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker as first-line antihypertensive among diabetics; (2) use of thiazide-type diuretics or calcium channel blockers among Black patients; (3) use of beta blockers among patients with compelling cardiac indication; (4) use of thiazide, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, or calcium channel blocker class as first line in all others; (5) beta blockers should be avoided as first line unless there is a compelling cardiac indication. A total of 372 254 cases from January 2010 to March 2020 are in the FSR with a diagnosis of acute ischemic stroke, hemorrhagic stroke, transient ischemic attack, or subarachnoid hemorrhage; 265 409 with complete data were included in the final analysis. Mean age was 70±14 years; 50% were women; and index stroke subtypes were 74% acute ischemic stroke, 11% intracerebral hemorrhage, 11% transient ischemic attack, and 4% subarachnoid hemorrhage. BP-guideline adherence to each specific rule ranged from 48% to 74%, which is below quality standards of 80%, and was lower among Black patients (odds ratio, 0.7 [95% CI, 0.7-0.83]; P<0.001) and those with atrial fibrillation (odds ratio, 0.53 [95% CI, 0.50-0.56]; P<0.001) and diabetes (odds ratio, 0.65 [95% CI, 0.61-0.68]; P<0.001). CONCLUSIONS: This large data set demonstrates consistently low rates of BP-guideline adherence over 10 years. There is an opportunity for monitoring hypertensive management after stroke.
RESUMEN
Racial inequities as illustrated by the health disparities in COVID19 infections and deaths, the recent killings of Black men and women by law enforcement, and the widening socioeconomic inequality and have brought systemic racism into a national conversation. These unprecedented times may have deleterious consequences, increasing stress, and trauma for many members of the neurology workforce. The Equity, Diversity, Inclusion and Anti-Racism Committee within our Department of Neurology provides infrastructure and guidance to foster a culture of belonging and addresses the well-being of faculty, staff, and trainees. Here, we present the creation and implementation of our Equity, Diversity, Inclusion, and Anti-Racism (EDIA) Pledge which was central to our committee's response to these unprecedented times. We outline the process of developing this unique EDIA Pledge and provide a roadmap for approaching these important topics through a CME Neurology Grand Rounds aimed at fostering a diverse, inclusive, equitable and antiracist work environment. Through the lived experiences of 4 faculty members, we identify the impact of bias and microaggressions, and encourage allyship and personal development for cultural intelligence. We hope these efforts will inspire Neurology departments and other academic institutions across the globe to make a similar pledge.
RESUMEN
Multiple sclerosis (MS) is a relapse remitting immune-mediated demyelinating neurological disorder that primarily affects women of childbearing age. In most patients, the hormonal changes during pregnancy are protective against MS relapses. When relapses do occur, treatment options are limited to use of intravenous steroids and plasmapheresis rescue therapy. We present a case of steroid refractory MS-transverse myelitis with quadriplegia in a 25-year-old pregnant super morbidly obese woman. Our clinical case is unique because the severity of her relapse early in pregnancy, which was intractable and resistant to steroids. This may have been a rebound demyelination due to the discontinuation of fingolimod; a newly recognized entity by the FDA. Our case report therefore seeks to raise awareness about a potential complication of discontinuing MS disease modifying therapies, highlighting that these rebound relapses can be steroid resistant and occur despite the usual protective hormonal influence of early pregnancy and that plasma exchange is a valid treatment option. Finally, we discuss the challenges of determining exchange volumes for plasmapheresis in the super morbid obese population to secure good maternal and fetal outcomes.
RESUMEN
Inclusion is the deliberate practice of ensuring that each individual is heard, all personal traits are respected, and all can make meaningful contributions to achieve their full potential. As coronavirus disease 2019 spreads globally and across the United States, we have viewed this pandemic through the lens of equity and inclusion. Here, we discuss how this pandemic has magnified preexisting health and social disparities and will summarize why inclusion is an essential tool to traverse this uncertain terrain and discuss strategies that can be implemented at organizational and individual levels to improve inclusion and address inequities moving forward.

OBJECTIVE: Moyamoya disease is a cerebral vasculopathy characterized by stenosis of the terminal internal carotid artery, proximal middle cerebral artery, and anterior cerebral artery. There is an association between moyamoya vasculopathy and Graves disease, primarily in Asian populations. Here, we present the largest series of non-Asian, predominantly Latino patients with moyamoya vasculopathy in the setting of Graves thyrotoxicosis, as well as the largest review of the literature to date. METHODS: We retrospectively analyzed patients presenting with stroke in the setting of clinical Graves disease to our institution from 2004 to 2014. Moyamoya vasculopathy was diagnosed by magnetic resonance angiography in all patients. RESULTS: Eight patients with Graves disease thyrotoxicosis and moyamoya vasculopathy were identified. Six patients were effectively managed with aggressive medical management using antithyroid and antiplatelet medications. No recurrent strokes were noted once thyrotoxicosis was controlled. Intracranial bypass was necessary in 2 patients who failed medical management. Seventy-nine additional cases were reported from the literature. There was no significant difference in clinical improvement between medical therapy alone and medical therapy with neurosurgical prophylaxis (87.0% vs. 88.0%, respectively; P = 0.94). CONCLUSIONS: Moyamoya vasculopathy associated with Graves disease thyrotoxicosis in non-Asian women may be more common than previously thought. In addition, our series suggests that thyrotoxicosis promotes the progression of vasculopathy. Based on our review, there is no significant difference in clinical improvement between proper medical and surgical therapies. Aggressive medical therapy should be considered first-line treatment for moyamoya vasculopathy with Graves thyrotoxicosis, with neurosurgical rescue reserved for medically refractory cases.

BACKGROUND: Vertebral artery origin stenosis is an important etiology for stroke in the posterior circulation. Data from the Oxford Vascular Study and New England Registry show a prevalence of vertebral artery origin disease of 26-32%. These populations are largely comprised of Caucasians. The prevalence of vertebral artery origin disease in multirace-ethnic stroke population is unknown. AIM: The study aims to assess the prevalence of vertebral artery origin stenosis in a multirace population with posterior circulation stroke. DESIGN/METHODS: The Miami Stroke Registry is a prospective registry which offers enrollment to consecutive patients admitted with a diagnosis of stroke/transient ischemic attack. Baseline demographics, vascular risk factors, and stroke topography in the posterior circulation were analyzed. All vascular imaging studies were reviewed for the presence of vertebral artery origin stenosis, and stroke etiology was adjudicated by TOAST classification. RESULTS: Mean age of the population was 63 ± 13 years; 149 (70%) were men. Among cases, 123 were Hispanic (58%), almost one third 70 (32%) were of African descent, and 15 (7%) were white. The most common stroke etiology was small vessel occlusion (27%), followed by large artery intracranial disease 25% (posterior cerebral arteries, basilar and vertebral arteries), cardioembolic 19%, and cryptogenic 16%. Vertebral artery origin stenosis/occlusion was present in 28 (13.1%) patients, of whom only 2 (0.9%) were bilateral; it was attributed as the direct cause of stroke in 11 (5.2%) patients. CONCLUSIONS: We found a lower prevalence of vertebral artery origin stenosis in a predominately non-white population with posterior circulation stroke than previously reported. Vertebral artery origin stenosis was a direct cause of posterior circulation stroke in only 5.2% of patients.
