Abstract
INTRODUCTION Untreated basilar artery occlusion (BAO) carries 70% mortality. Guidelines recommend thrombectomy with or without thrombolysis. AIM We compared Modified Rankin Scores (mRS) at 3 and 12 months post thrombectomy to determine benefit of long-term follow up. METHODS Retrospective, single centre analysis of BAO thrombectomies between 2015 and 2019. Inclusion criteria were symptomatic BAO on CT angiography, absent early ischemic changes, premorbid independence and intervention within 24 h. All received stroke ward care. Results were analysed with simple statistics and binary logistic regression as appropriate. RESULTS Of 82 patients: most were male (61%, 50/82) with median age 68 years (IQR 17 years) and median NIHSS 14 (IQR 15). Median door-to-puncture time was 42 min (IQR 72 min). Total deaths were 34.1% (28/82) at 3 months, and 37.8% (31/82) at 12 months. Of 51 patients alive at 12 months: 41% (21/51) had improved mRS, 16% (8/51) had worse mRS and 43% (22/51) had unchanged mRS, compared to 3 months. Improvements to mRS were: one point in 57.1% (14/21), two points in 28.9% (6/21) and three points in 4.8% (1/21). Nursing home admission was avoided in 11.8% (6/51) who improved from mRS4. Increased age was associated with decreased likelihood of reaching the primary outcome OR 0.87, 95% CI 0.76-0.99 (p value = 0.03). CONCLUSION Over a quarter of patients improved beyond 3 months. Future studies should adopt long-term follow up as primary outcome.

Abstract
Background and purposePrior studies on sex disparities were post-hoc analyses, had limited treatment modalities, and had controversial findings. Our study aimed to examine whether sex difference modifies the effect of intravenous alteplase before endovascular therapy.MethodsWe conducted a multicenter prospective cohort study of 850 eligible patients with acute ischemic stroke who underwent endovascular therapy. A propensity score was utilized as a covariate to achieve approximate randomization of alteplase pretreatment. The baseline characteristics of women and men were compared. Logistic regression with interaction terms, adjusted for potential confounders, was used to investigate the effect of sex on the prognosis of bridging therapy.ResultsIn comparison to men, women were older [78.00 (70.00–84.00) vs. 67 (61.00–74.00), P < 0.001], had more atrial fibrillation (61.4 vs. 35.2%, P < 0.001), had a lower ASPECTS [10.00 (8.00–10.00) vs. 10 (9.00–10.00), P = 0.0047], and had a higher NIHSS score [17.00 (14.00–20.00) vs. 16 (13.00–19.00), P = 0.005]. Women tended to receive less bridging therapy (26.3 vs. 33%, P = 0.043) and more retrieval attempts [2.00 (1.00–2.00) vs. 1 (1.00–2.00), P = 0.026]. There was no sex difference in functional independence at 90 days after bridging therapy (OR 0.968, 95% CI 0.575–1.63), whereas men benefited more after EVT alone (OR 0.654, 95% CI 0.456–0.937). There were no sex-treatment interactions observed regardless of the location of the occlusion. There were no significant sex differences in all safety outcomes.ConclusionOur study could not confirm that sex modifies the treatment effect of intravenous alteplase before endovascular therapy. At the same time, we advocate for women to seek timely medical treatment.

Abstract
BACKGROUND AND PURPOSE The benefit of thrombectomy (TE) for acute ischemic stroke (AIS) in patients suffering basilar artery occlusion (BAO) is still unclear. Our aim was to analyze functional outcome after 3 months in BAO compared to anterior circulation large vessel occlusion (ACLVO) in a nationwide registry. METHODS Patients enrolled into the Austrian Endostroke Registry from 2013 to 2018 were analyzed. We used propensity score matching to control for imbalances and to compare patients with BAO and ACLVO. The primary outcome was favorable functional outcome after 3 months measured by the modified Rankin Scale (mRS) (0-2). Multivariate models were applied to estimate the effect of localization (BAO vs ACLVO). RESULTS In total, 2288 patients underwent TE for AIS with proximal vessel occlusion, of these 267 with BAO. Two hundred and sixty-four patients with BAO were matched to 264 patients with ACLVO. Baseline characteristics were well-balanced. The 90-day mortality did not significantly differ between patients with BAO and ACLVO. In a multivariate logistic regression model, we did not detect a significant difference in functional outcome between BAO and ACLVO (odds ratio for favorable outcome defined as mRS = 0-2: 1.19; 95% confidence interval (CI) = 0.78-1.81; p = 0.42). In patients with an onset-to-door-time ⩾270 min, TE of BAO was associated with poor functional outcome defined as mRS 3-6 (odds ratio (OR) = 3.97; 95% CI = 1.32-11.94; p = 0.01) as compared to ACLVO. CONCLUSION In this study, functional outcome did not differ after TE in patients with BAO and ACLVO overall; however, we detected an association of BAO with poor outcome in patients arriving late.

J Stroke Cerebrovasc Dis 2020; 29:105240. [PMID: 33066881 DOI: 10.1016/j.jstrokecerebrovasdis.2020.105240] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 08/04/2020] [Accepted: 08/06/2020] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Gender differences are often reported in the field of ischemic stroke, although most of such discrepancies were observed in randomized trials involving highly selected populations. We therefore explored gender differences regarding 90-day outcomes in large vessel occlusion (LVO) strokes receiving endovascular treatment in a real world setting. METHODS This prospective registry included anterior and/or posterior circulation LVO strokes admitted between January 2014 and December 2019 who received mechanical thrombectomy up to 24 hours from symptoms onset or last known to be well. We explored sex-related differences in rates of functional independence (modified Rankin Scale, mRS, ≤2) at 90 days. Secondary outcomes included "National Institutes of Health Stroke Scale" (NIHSS) at 24 hours, successful reperfusion defined as modified Thrombolysis in Cerebral Infarction (mTICI) scale 2b/3, death, and symptomatic intracranial hemorrhage (sICH). RESULTS A total of 288 LVO stroke patients comprised the study population, involving 148 (51.4%) women. Females were older (71.4±15.7 vs. 66.1±14.0 years, p=0.003) and had lower rates of coronary artery disease (15% vs. 24%, p=0.05). The median time from symptoms onset to hospital arrival was 315 min (IQR 139.5-495.0) in females and 255.0 (IQR 117.0-405.0) in males (p=0.052). Rates of mRS ≤2 at 90 days were comparable (females 46% vs. males 49%, p=0.50). Successful reperfusion was achieved in 82% of females and 89% of males (p=0.10). Rates of sICH (females 10% vs. males 13%, p=0.47) and death (females 18% vs. males 21%, p=0.50) at 90 days were similar. NIHSS at 24 hours was the strongest predictor of functional independence at 90 days (area under ROC curve 0.92 (95%CI 0.87; 0.95)]. CONCLUSIONS Our prospective registry involving a real world setting suggests that females are equally likely to achieve good outcomes after endovascular treatment despite being older and having delayed hospital arrival compared to males. In addition, we found that NIHSS at 24 hours was the strongest predictor of functional independence at 90 days, sICH, and death.

Abstract
Vertebral artery dissection (VAD) followed by basilar artery occlusion/stroke (BAO/BAS) is a rare but potentially life-threatening complication. We present a case report of a 7-year-old boy with VAD complicated by BAO/BAS 4 days after falling off a scooter. Symptoms included left-sided weakness and facial droop preceded by a 20-minute episode of altered sensorium. Magnetic resonance imaging showed ischemic changes in the left posterior inferior cerebellum and right pons. Computed tomography angiogram confirmed dissection of the left vertebral artery with occlusion/thrombosis of the basilar artery. Heparinization for 96 hours, followed by 6 months of low-molecular weight heparin injection, resulted in improvement of his neurological symptoms.

Abstract
Supplemental Digital Content is available in the text. Previous studies have reported less favorable outcome and less effect of endovascular treatment (EVT) after ischemic stroke in women than in men. Our aim was to study the influence of sex on outcome and on the effect of EVT for ischemic stroke in recent randomized trials on EVT.

Abstract
OBJECTIVE Presentation of the own experience in the treatment of ischemic stroke using endovascular methods of simultaneous evaluation of their effectiveness and safety. MATERIALS AND METHODS The retrospective study involved a group of 18 patients hospitalized in 2005-2012 who were treated with intraarterial thrombolysis and mechanical thrombectomy. Overall there were 24 procedures performed. The investigated group consisted of seven (38.89%) women and 11 (61.11%) men. The average age of the patients was 60 years (SD ± 17, median - 60 years). RESULTS In 62.50% of cases (n=15) the effect of revascularization has been achieved and another 12.50% of cases (n=3) recanalization was achieved only partially. Only in 25% of procedures (n=6) failed to achieve recanalization of the artery (TICI ≤ 1). The highest percentage of recanalized arteries were obtained by following the procedure of thrombolysis targeted - 69.24% (TICI ≥ 2b). In the case of mechanical thrombectomy total patency (TICI ≥ 2b) was 54.55%. The average duration of treatment (operation) is 157 min. After 30 days successful result of the neurological status was achieved in 57.14% of patients (n=8). Full return to independent functioning as defined within 3 months after the surgery (mRS ≤ 2) reached 57.14% of patients (n=8). CONCLUSION Studies suggest that endovascular techniques are effective and safe in the treatment of ischemic stroke. Greater efficiency is characterized by intraarterial thrombolysis. Patients who were treated endovascular improved significantly.

Abstract
We describe the current and future objectives of the Women Stroke Association, a nonprofit multidisciplinary organization promoting research awareness on medical, psychological, and social issues concerning women affected by cerebrocardiovascular disease. In this paper, we deal with only cerebrovascular disease, whereas cardiovascular disorders will be addressed in a future paper. Gender differences in the clinical presentation of cerebrovascular diseases have been repeatedly suggested, and some treatment options may not be as effective and safe in men and women. For many years, women have either been underrepresented or excluded from randomized clinical trials, and the majority of therapeutic research has been carried on predominantly male populations. Furthermore, gender differences have been shown to contribute to different responses to cerebrovascular drugs in women when compared with men, regarding pharmacokinetics, pharmacodynamics, and physiology. In this statement, we discuss main research fields relevant to Women Stroke Association's mission and commitment, highlighting opportunities and critical from the women's health perspective. Future directions and goals of the Women Stroke Association arise from these considerations and represent the association's commitment to combating stroke.

Abstract
Objective:To identify predictors of good outcome in acute basilar artery occlusion (BAO).Background:Acute ischemic stroke (AIS) caused by BAO is often associated with a severe and persistent neurological deficit and a high mortality rate.Methods:The set consisted of 70 consecutive AIS patients (51 males; mean age 64.5±14.5 years) with BAO. The role of the following factors was assessed: baseline characteristics, stroke risk factors, pre-event antithrombotic treatment, neurological deficit at time of treatment, estimated time to therapy procedure initiation, treatment method, recanalization rate, change in neurological deficit, post-treatment imaging findings. 30- and 90-day outcome was assessed using the modified Rankin scale with a good outcome defined as a score of 0–3.Results:The following statistically significant differences were found between patients with good versus poor outcomes: mean age (54.2 vs. 68.9 years; p=0.0001), presence of arterial hypertension (52.4% vs. 83.7%; p=0.015), diabetes mellitus (9.5% vs. 55.1%; p=0.0004) and severe stroke (14.3% vs. 65.3%; p=0.0002), neurological deficit at time of treatment (14.0 vs. 24.0 median of National Institutes of Health Stroke Scale [NIHSS] points; p=0.001), successful recanalization (90.0% vs. 54.2%; p=0.005), change in neurological deficit (12.0 vs. 1.0 median difference of NIHSS points; p=0.005). Stepwise binary logistic regression analysis identified age (OR=0.932, 95% CI=0.882–0.984; p=0.012), presence of diabetes mellitus (OR=0.105, 95% CI=0.018–0.618; p=0.013) and severe stroke (OR=0.071, 95% CI=0.013–0.383; p=0.002) as significant independent negative predictors of good outcome.Conclusions:In the present study, higher age, presence of diabetes mellitus and severe stroke were identified as significant independent negative predictors of good outcome.

Abstract
Acute basilar artery occlusion (ABAO) is an infrequent but potentially fatal complication that can cause strokes in both adults and children. Traumatic vertebral artery dissection (VAD) is one of the most common causes of ABAO in young patients. We present a case of an 11-year-old boy with VAD complicated by basilar artery occlusion 2 days after a fight with classmates that caused severe neurological deficits. He did not have any direct head trauma or concomitant risk factors. Clinical symptoms included nausea, vomiting, and rapid alteration of consciousness. Magnetic resonance imaging showed total occlusion of the basilar artery, and angiography confirmed VAD from the third to the fourth segments. A history of such subtle precipitating events should be noted when diagnosing young patients with brainstem strokes. A delay in the diagnosis of ABAO is frequently due to misleading symptoms and signs and the lack of awareness of this rare condition.

Abstract
Background and Purpose Aggressive treatment of posterior-circulation occlusions is important due to the high rates of morbidity and mortality associated with these infarctions. A large administrative database was evaluated to determine the outcomes of mechanical thrombectomy and intravenous tissue plasminogen activator (IV-tPA) for the treatment of posterior-circulation (vertebrobasilar) strokes. Outcomes were compared across age groups. Methods The United States Nationwide Inpatient Sample was used to evaluate the outcomes of patients treated for posterior-circulation acute ischemic stroke between 2006 and 2010. Patients who underwent endovascular mechanical thrombectomy and IV-tPA were selected. Primary outcomes were discharge status and mortality; secondary outcomes were length of stay, rate of intracranial hemorrhage, tracheostomy, and percutaneous endoscopic gastrostomy/jejunostomy tube placement. Outcomes were grouped according to age (i.e., <50, 50-64, and ≥65 years). Chi-squared test and Student's t-test were used for comparisons of categorical and continuous variables, respectively. Results During 2006-2010 there were 36,675 patients who had discharge International Classification of Diseases (9th edition) codes indicating posterior-circulation strokes. Of these, 631 (1.7%) underwent mechanical thrombectomy and 1554 (4.2%) underwent IV-tPA. The in-hospital mortality rate for mechanical thrombectomy patients was significantly lower for those aged <50 years than for those aged 50-64 years (30.4% versus 47.4%, p<0.01) and those aged ≥65 years (30.4% versus 43.0%, p≤0.01). Age had no effect on the in-hospital mortality for IV-tPA patients, with an incidence of 22.7% for patients aged <50 years, compared to 25.4% for patients aged 50-64 years (p=0.46) and 23.0% for patients aged ≥65 years (p=0.92). Conclusions Patients requiring IV-tPA and/or mechanical thrombectomy for the treatment of posterior-circulation strokes suffer from high mortality rates. Increased age is associated with significantly higher mortality rates among posterior-circulation stroke patients who require mechanical thrombectomy.

Abstract
BACKGROUND Studies suggest that women are less likely than men to receive intravenous (IV) tissue plasminogen activator (tPA) for acute ischemic stroke (AIS). Relatively little is known about whether this sex disparity in AIS management extends beyond IV tPA use, reflects national practice patterns, or is changing. METHODS Data from the Nationwide Inpatient Sample from 1997 to 2006 were used to identify adults (≥18 years of age) who were discharged with a primary diagnosis of AIS (n = 4,453,207) in the United States. Of 605,960 individuals admitted to 1056 hospitals that performed reperfusion/revascularization procedures, sex-specific rates of cerebrovascular reperfusion (e.g., IV tPA, intra-arterial therapy, angioplasty, stent, or carotid endarterectomy [CEA]), and cardiac reperfusion (e.g., catheterization, angioplasty, stent, or bypass graft) were determined before and after adjustment for sociodemographic, clinical, and hospital factors. RESULTS Men were more likely than women to receive IV tPA (prevalence ratio [PR] 1.37, 95% confidence interval [CI] 1.32-1.42), catheter angiography (PR 1.36, 95% CI 1.33-1.38), intracranial or extracranial angioplasty/stent (PR 1.73, 95% CI 1.49-2.01), CEA (PR 1.79, 95% CI 1.72-1.86), or any cardiac reperfusion therapy (PR 1.62, 95% CI 1.53-1.71). Multivariable adjustment slightly attenuated the sex disparity. Use of all procedures except CEA rose from 1997 to 2006 in both sexes, but IV tPA use increased at a higher rate for women (compared to men); by 2006, there was no sex difference. CONCLUSIONS Over the last decade, women hospitalized for AIS in the United States were less likely than men to receive cerebrovascular and cardiac reperfusion therapies. However, the IV tPA treatment sex disparity may have been eliminated.

Abstract
Ischemic stroke is emerging as a major health problem for elderly women. Women have lower stroke incidence than men until an advanced age, when the epidemiology of ischemic stroke shifts and incidence rises dramatically in women. Experimental models of rodent stroke have replicated this clinical epidemiology, with exacerbated injury in older compared with young female rodents. Many of the detrimental effects of aging on ischemic stroke outcome in females can be replicated by ovariectomy, suggesting that hormones such as estrogen play a neuroprotective role. However, emerging data suggest that the molecular mechanisms leading to ischemic cell death differ in the two sexes, and these effects may be independent of circulating hormone levels. This article highlights recent clinical and experimental literature on sex differences in stroke outcomes and mechanisms.
