Abstract
BACKGROUND Stroke etiology could influence the outcomes in patients with basilar-artery occlusion (BAO). This study aimed to evaluate the differences in efficacy and safety of best medical treatment (BMT) plus endovascular treatment (EVT) versus BMT alone in acute BAO across different stroke etiologies. METHODS The study was a post hoc analysis of the ATTENTION trial (Trial of Endovascular Treatment of Acute Basilar-Artery Occlusion), which was a multicenter, randomized trial at 36 centers in China from February 2021 to September 2022. Patients with acute BAO were classified into 3 groups according to stroke etiology (large-artery atherosclerosis [LAA], cardioembolism, and undetermined cause/other determined cause [UC/ODC]). The primary outcome was a favorable outcome (modified Rankin Scale score of 0-3) at 90 days. Safety outcomes included symptomatic intracranial hemorrhage and 90-day mortality. RESULTS A total of 340 patients with BAO were included, 150 (44.1%) had LAA, 72 (21.2%) had cardioembolism, and 118 (34.7%) had UC/ODC. For patients treated with BMT plus EVT and BMT alone, respectively, the rate of favorable outcome at 90 days was 49.1% and 23.8% in the LAA group (odds ratio, 3.08 [95% CI, 1.38-6.89]); 52.2% and 30.8% in the cardioembolism group (odds ratio, 2.45 [95% CI, 0.89-6.77]); and 37.5% and 17.4% in the UC/ODC group (odds ratio, 2.85 [95% CI, 1.16-7.01]), with P=0.89 for the stroke etiology×treatment interaction. The rate of symptomatic intracranial hemorrhage in EVT-treated patients with LAA, cardioembolism, and UC/ODC was 8.3%, 2.2%, and 3.2%, respectively, and none of the BMT-treated patients. Lower 90-day mortality was observed in patients with EVT compared with BMT alone across 3 etiology groups. CONCLUSIONS Among patients with acute BAO, EVT compared with BMT alone might be associated with favorable outcomes and lower 90-day mortality, regardless of cardioembolism, LAA, or UC/ODC etiologies. The influence of stroke etiology on the benefit of EVT should be explored by further trials. REGISTRATION URL: https://www.clinicaltrials.gov; Unique identifier: NCT04751708.

Abstract
The aim of the present European Stroke Organisation (ESO) guideline is to provide evidence-based recommendations on the acute management of patients with basilar artery occlusion (BAO). These guidelines were prepared following the Standard Operational Procedure of the ESO and according to the GRADE methodology.Although BAO accounts for only 1-2% of all strokes, it has very poor natural outcome. We identified 10 relevant clinical situations and formulated the corresponding Population Intervention Comparator Outcomes (PICO) questions, based on which a systematic literature search and review was performed. The working group consisted of 10 voting members (five representing ESO and five representing the European Society of Minimally Invasive Neurological Therapy (ESMINT)) and three non-voting junior members. The certainty of evidence was generally very low. In many PICOs, available data were scarce or lacking, hence, we provided expert consensus statements.First, we compared intravenous thrombolysis (IVT) to no IVT, but specific BAO-related data do not exist. Yet, historically, IVT was standard of care for BAO patients who were also included (although in small numbers) in IVT trials. Non-randomized studies of IVT-only cohorts showed a high proportion of favorable outcomes. Expert Consensus suggests using IVT up to 24 hours unless otherwise contraindicated. We further suggest IVT plus endovascular treatment (EVT) over direct EVT. EVT on top of best medical treatment (BMT) was compared with BMT alone within 6 and 6-24 hours from last seen well. In both time windows, we observed a different effect of treatment depending on a) the region where the patients were treated (Europe vs Asia), b) on the proportion of IVT in the BMT arm, and c) on the initial stroke severity. In case of high proportion of IVT in the BMT group and in patients with a National Institutes of Health Stroke Scale (NIHSS) score below 10, EVT plus BMT was not found better than BMT alone. Based on very low certainty of evidence, we suggest EVT+BMT over BMT alone (this is based on results of patients with at least 10 NIHSS points and a low proportion of IVT in BMT). For patients with an NIHSS score below 10, we found no evidence to recommend EVT over BMT. In fact, BMT was non-significantly better and safer than EVT. Furthermore, we found a stronger treatment effect of EVT+BMT over BMT alone in proximal and middle locations of BAO compared with distal location. While recommendations for patients without extensive early ischemic changes in the posterior fossa can, in general, follow those of other PICOs, we formulated an Expert Consensus Statement suggesting against reperfusion therapy in those with extensive bilateral and/or brainstem ischemic changes. Another Expert Consensus suggests reperfusion therapy regardless of collateral scores. Based on limited evidence, we suggest direct aspiration over stent retriever as the first-line strategy of mechanical thrombectomy. As an Expert Consensus, we suggest rescue percutaneous transluminal angioplasty and/or stenting after a failed EVT procedure. Finally, based on very low certainty of evidence, we suggest add-on antithrombotic treatment during EVT or within 24 hours after EVT in patients with no concomitant IVT and in whom EVT was complicated (defined as failed or imminent re-occlusion, or need for additional stenting or angioplasty).

Abstract
BACKGROUND Futile recanalization (FR) after endovascular therapy (EVT) is common in basilar artery occlusion (BAO). The purpose of this study was to investigate the predictors of FR in the posterior circulation with an emphasis on the role of perfusion imaging and its relation to the underlying etiology. METHODS We included BAO patients who had pretreatment perfusion imaging and successful recanalization after EVT. Patients were dichotomized into futile and non-futile groups according to the favorable functional outcome at 90 days (modified Rankin Scale (mRS) 0-3). Perfusion abnormalities were assessed using an automated software for Tmax volume measurement and identification of hypoperfusion area based on Tmax>6 s involvement of the pons-midbrain-thalamus (PMT), cerebellum, and temporo-occipital lobe. RESULTS Of the 134 enrolled patients, the incidence of FR was 47.8% (64/134). Multivariate logistic analysis showed that a higher National Institutes of Health Stroke Scale (NIHSS) score on admission (adjusted OR (aOR) 1.066; 95% CI 1.011 to 1.125), a longer onset-to-recanalization time (aOR 1.002; 95% CI 1.001 to 1.004), incomplete recanalization (aOR 3.909; 95% CI 1.498 to 10.200), and PMT hypoperfusion (aOR 4.444; 95% CI 1.203 to 16.415) were independent predictors of FR. In patients with embolic occlusion of etiology, PMT hypoperfusion was associated with FR (aOR 8.379; 95% CI 1.377 to 50.994), whereas intracranial atherosclerotic stenosis (ICAS)-related occlusion was not (p=0.587). CONCLUSIONS In patients with BAO, the likelihood of FR is associated with PMT hypoperfusion on pretreatment perfusion imaging. In particular, PMT hypoperfusion may be used as an imaging predictor of FR in patients with embolic cause of BAO.

Abstract
BACKGROUND Thrombus enhancement sign (TES) is associated with cardioembolic stroke and first-pass angiographic failure in anterior ischemic stroke. However, the relationship between TES and stroke subtype and recanalization status after endovascular treatment (EVT) in basilar artery occlusion (BAO) remains unknown. METHODS This retrospective study included consecutive patients with acute BAO who underwent EVT between January 2020 and September 2023. Each patient underwent baseline non-contrast computed tomography (CT) and CT angiography. Two independent readers assessed the presence of TES. Stroke types were classified according to the Trial of ORG 10172 for Acute Stroke Treatment. Successful recanalization was defined as a modified Thrombolysis in Cerebral Infarction score of 2b-3 after EVT. Clinical and interventional parameters, along with histopathological thrombi examination results, were compared between the TES-positive and TES-negative groups. The associations between TES and stroke subtype and recanalization status were analyzed using univariate and multivariate analyses. RESULTS A total of 151 patients were included in the analysis, among whom 116 (77%) exhibited TES. TES showed a significant correlation with cardioembolic and cryptogenic strokes (odds ratio [OR]: 8.56; 95% confidence interval: 3.49-22.4; p < 0.001), whereas the TES-positive thrombi were characterized by a higher fibrin/platelet proportion (p = 0.002) and lower erythrocyte proportion (p = 0.044). The TES-positive group demonstrated favorable outcomes compared to the TES-negative group, including a shorter procedure time (p < 0.001), lower number of thrombectomy attempts (p = 0.010), higher incidence of first pass success (p = 0.022), and lower rate of requiring rescue angioplasty and/or stenting (p < 0.001). In multivariate analysis, TES remained independently associated with successful recanalization (OR: 9.63; 95% CI: 2.33, 47.7; p = 0.003) after adjusting for baseline confounders. CONCLUSIONS Visualization of TES serves as a reliable and easily accessible marker for identifying cardioembolic and cryptogenic strokes and predicting recanalization success in thrombectomy for basilar artery occlusion.

Abstract
OBJECTIVE To compare the efficacy and safety of intravenous thrombolysis, direct endovascular therapy (EVT), and bridging therapy (BT = intravenous thrombolysis + EVT) for acute basilar artery occlusion cerebral infarction. METHODS One hundred and fourteen patients with acute basilar artery occlusion cerebral infarctions admitted between January 2020 and August 2023 were selected. Differences in the reperfusion rate, prognosis, incidence of stroke-associated pneumonia, and mortality rate were compared among the 3 groups. RESULTS There was no statistically significant difference in the percentage of patients who achieved successful reperfusion (86.8% vs. 84.2%) or complete reperfusion (72.1% vs. 68.4%) between the direct EVT and BT groups (both P > 0.05). There were no statistically significant differences in the rates of symptomatic intracranial hemorrhage (3.7% vs. 10.3% vs. 10.5%, P = 0.763). There were statistically significant differences in the rates of good prognosis (modified ranking scale score 0-2) (59.3% vs. 30.9% vs. 26.3%, P = 0.021), stroke-related pneumonia (29.6% vs. 66.2% vs. 36.8%, P = 0.002), and mortality (14.8% vs. 48.5% vs. 42.1%, P = 0.010) among the 3 treatment groups. According to the binary logistic regression analysis, a good prognosis was independently associated with a baseline National Institutes of Health Stroke Scale score ≤ 10 (odds ratio, 3.714; 95% confidence interval, 1.207-11.430; P = 0.022) and the incidence of stroke-associated pneumonia (odds ratio, 0.640; 95% confidence interval, 0.484-0.845; P = 0.002). CONCLUSIONS Although there were differences in prognosis, mortality, and incidence of complications among the 3 treatment groups, after adjusting for confounding factors, prognosis was independently correlated only with the baseline NIHSS score and stroke-associated pneumonia but not with treatment methods.

Outcome of Mechanical Thrombectomy for Acute Basilar Artery Occlusion in Patients with Intracranial Atherosclerotic Disease. Cerebrovasc Dis 2024:1-12. [PMID: 38684148 DOI: 10.1159/000539112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 04/21/2024] [Indexed: 05/02/2024] Open
Abstract
INTRODUCTION Intracranial atherosclerotic disease (ICAD) has been identified as a major cause of acute basilar artery occlusion (BAO).This study compared the characteristics and treatment outcomes in acute BAO patients with and without ICAD. METHODS A prospective cohort study was conducted at 115 People's Hospital, Ho Chi Minh city, Vietnam from August 2021 to June 2023. Patients with acute BAO who underwent endovascular treatment within 24 h from symptom onset were included (thrombectomy alone or bridging with intravenous alteplase). The baseline characteristics and outcomes were analyzed and compared between patients with and without ICAD. Good functional outcome was defined as mRS ≤3 at 90 days. RESULTS Among the 208 patients enrolled, 112 (53.8%) patients were categorized in the ICAD group, and 96 (46.2%) in the non-ICAD group. Occlusion in the proximal segment of the basilar artery was more common in patients with ICAD (55.4% vs. 21.9%, p < 0.001), whereas the distal segment was the most common location in the non-ICAD group (58.3% vs. 10.7%, p < 0.001). Patients in the ICAD group were more likely to undergo treatment in the late window, with a higher mean onset-to-treatment time compared to the non-ICAD group (11.6 vs. 9.5 h, p = 0.01). In multivariable logistic regression analysis, distal segment BAO was negatively associated with ICAD (aOR 0.13, 95% CI: 0.05-0.32, p < 0.001), while dyslipidemia showed a positive association (aOR 2.44, 95% CI: 1.15-5.17, p = 0.02). There was a higher rate for rescue stenting in the ICAD compared to non-ICAD group (15.2% vs. 0%, p < 0.001). However, no significant differences were found between the two groups in terms of good outcome (45.5% vs. 44.8%, p = 0.91), symptomatic hemorrhage rates (4.5% vs. 8.3%, p = 0.25), and mortality (42% vs. 50%, p = 0.25). CONCLUSION ICAD was a common etiology in patients with BAO. The location segment of BAO and dyslipidemia were associated with ICAD in patients with BAO. There was no difference in 90-day outcomes between BAO patients with and without ICAD undergoing endovascular therapy.

Impact of ischemic stroke topography on early clinical outcome of basilar artery occlusion: a retrospective study. Eur Radiol 2024:10.1007/s00330-024-10755-y. [PMID: 38662099 DOI: 10.1007/s00330-024-10755-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 03/01/2024] [Accepted: 03/17/2024] [Indexed: 04/26/2024]
Abstract
OBJECTIVES Basilar artery occlusion (BAO) may be etiologically attributed to embolism or in situ thrombosis due to basilar stenosis (BS). Patients with BAO due to BS (BAOS) are known to have worse outcomes than patients with embolic occlusions (BAOE). BAOS occurs more proximally in the basilar artery (BA) than BAOE. We hypothesize that differing brain stem infarct patterns contribute to outcome differences between these stroke etiologies. METHODS This retrospective study includes 199 consecutive patients with BAO who received endovascular treatment at a single center. Final infarction in brain parenchyma dependent on the posterior circulation was graded semiquantitatively on magnetic resonance imaging (MRI). Associations to underlying stenosis and angiographic and clinical outcome variables were tested. The primary endpoint was early good clinical outcome (EGCO, mRS score ≤ 3 at discharge). RESULTS Infarct extension of the medulla oblongata (OR = 0.25; 95% CI = 0.07-0.86; p = 0.03), the inferior pons (OR = 0.328; 95% CI = 0.17-0.63; p = 0.001), the superior pons (OR = 0.57; 95% CI = 0.33-0.99; p = 0.046), and the occipital lobes (OR = 0.46; 95% CI = 0.26-0.80; p = 0.006) negatively predicted EGCO. Infarct extension for other posterior-circulation-dependent brain regions was not independently associated with unfavorable early outcomes. Patients with BAOS had more proximal occlusions and greater infarct volumes in the inferior brain stem. Successful reperfusion (mTICI 2b-3) occurred more often in patients with BAOE than in BAOS (BAOE: 131 (96.3%); BAOS: 47 (83.9%), p = 0.005). CONCLUSION Unfavorable early outcomes in patients with BAOS may be explained by a higher likelihood of inferior brain stem infarcts and lower rates of reperfusion success. CLINICAL RELEVANCE STATEMENT Basilar artery occlusion due to underlying stenosis is associated with a poorer prognosis than that caused by embolism; these results suggest that aggressive endovascular therapy, usually involving the placement of a permanent stent, may be warranted in these patients. KEY POINTS Inferior brain stem and occipital infarcts are prognostically unfavorable in basilar artery occlusion. Basilar artery occlusion due to stenosis occurs more proximally and is associated with worse outcomes. Differentiating etiologies of basilar artery occlusion may influence how aggressively treated the occlusion is.

Abstract
BACKGROUND Acute basilar artery occlusion (BAO) is a severe disease that is associated with an 85% mortality rate if untreated. Several studies have analyzed the use of mechanical thrombectomy (MT) in the different scenarios of BAO. However, the results remain conflicting and the role of MT as standard of care for vertebrobasilar tandem occlusions (VBTO) has not been confirmed. Our goal was to assess technical feasibility, safety, and functional outcome of endovascular treatment of VBTO in comparison to isolated BAO (IBAO). METHODS We retrospectively reviewed all prospectively collected patients with acute BAO from six tertiary centers between September 2016 and November 2021. Patients were subsequently divided into two groups: VBTO and IBAO. Baseline data, procedural details, and outcomes were compared between groups. RESULTS A total of 190 patients were included, 55 presenting with a VBTO and 135 with IBAO. Successful recanalization was equally common in both groups (89.1% and 86.0%). Rates of favorable functional outcome (modified Rankin Scale: 0-2) were higher in patients with VBTO compared to IBAO (36.4% vs. 25.2%, p = 0.048) and mortality was lower (29.1% vs. 33.3%). However, these associations faded after adjustment for confounders (adjusted odds ratio [aOR] 0.86, 95% CI 0.35-2.05; aOR 0.93, 95% CI 0.35-2.45). Rates of symptomatic intracranial hemorrhage did not differ between the groups (VBTO: 7.3% vs. IBAO: 4.2%; p = 0.496). CONCLUSION Endovascular treatment of VBTO is technically feasible and safe with similar rates of successful recanalization, favorable functional outcome, and mortality to those in patients with IBAO.

Abstract
BACKGROUND This study aimed to establish and validate a nomogram model for predicting 90-day mortality in patients with acute basilar artery occlusion receiving endovascular thrombectomy. METHODS AND RESULTS A total of 242 patients with basilar artery occlusion undergoing endovascular thrombectomy were enrolled in our study, in which 172 patients from 3 stroke centers were assigned to the training cohort, and 70 patients from another center were assigned to the validation cohort. Univariate and multivariate logistic regression analyses were adopted to screen prognostic predictors, and those with significance were subjected to establish a nomogram model in the training cohort. The discriminative accuracy, calibration, and clinical usefulness of the nomogram model was verified in the internal and external cohorts. Six variables, including age, baseline National Institutes of Health Stroke Scale score, Posterior Circulation-Alberta Stroke Program Early CT (Computed Tomography) score, Basilar Artery on Computed Tomography Angiography score, recanalization failure, and symptomatic intracranial hemorrhage, were identified as independent predictors of 90-day mortality of patients with basilar artery occlusion and were subjected to develop a nomogram model. The nomogram model exhibited good discrimination, calibration, and clinical usefulness in both the internal and the external cohorts. Additionally, patients were divided into low-, moderate-, and high-risk groups based on the risk-stratified nomogram model. CONCLUSIONS Our study proposed a novel nomogram model that could effectively predict 90-day mortality of patients with basilar artery occlusion after endovascular thrombectomy and stratify patients with high, moderate, or low risk, which has a potential to facilitate prognostic judgment and clinical management of stroke.

Abstract
BACKGROUND Among acute vertebrobasilar artery occlusion (VBAO) patients, successful reperfusion is a strong predictor of favorable outcomes. However, failed reperfusion (FR) with endovascular thrombectomy (EVT) in VBAO was observed to occur in 18-50% of cases. We aim to evaluate the safety and efficacy of rescue stenting (RS) for VBAO after failed EVT. METHODS Patients with VBAO who received EVT were enrolled retrospectively. Propensity score matching was performed as the primary analysis to compare the outcomes between patients with RS and FR. Furthermore, a comparison between using the self-expanding stent (SES) and balloon-mounted stent (BMS) in the RS group was also conducted. The primary and secondary outcomes were defined as a 90-day modified Rankin Scale (mRS) score 0-3, and a 90-day mRS score 0-2, respectively. Safety outcomes included all-cause mortality at 90 days and symptomatic intracranial hemorrhage (sICH). RESULTS The RS group showed a significantly higher rate of 90-day mRS score 0-3 (46.6% vs 20.7%; adjusted OR (aOR) 5.06, 95% CI 1.88 to 13.59, P=0.001) and a lower rate of 90-day mortality (34.5% vs 55.2%; aOR 0.42, 95% CI 0.23 to 0.90, P=0.026) than the FR group. The rates of 90-day mRS score 0-2 and sICH were not significantly different between the RS group and FR group. There were no differences in all outcomes between SES and BMS groups. CONCLUSIONS RS appeared to be a safe and effective rescue approach in patients with VBAO who failed EVT, and there was no difference between using SES and BMS.

Abstract
Background Intracranial arterial stenosis (ICAS), caused by intracranial atherosclerosis, is one of the major causes of ischemic stroke. This study identified the top 100 most-cited publications on ICAS through a bibliometric analysis. Methods Two independent authors conducted a search in the Web of Science database for clinical articles on ICAS published between 1993 and 2022. The top 100 most-cited articles were then extracted. For each article, the analysis covered the title, author, country of origin/affiliation, journal, total number of citations, number of citations per year, and type of study. Results The top 100 most-cited papers in the ICAS were authored by 565 authors from 12 countries and published in 29 journals. In terms of the 5-year trend, the largest number of papers were published between 2003 and 2007 (n = 31). The median number of citations for the 100 papers was 161 (range 109-1,115). The journal with the highest proportion of the 100 most published articles was Stroke, accounting for 41% of articles and 37% of the citations. According to country of origin, the United States of America accounted for the largest number of articles, followed by China, Japan, and South Korea, with these four countries together accounting for 81% of the total number of articles and 88% of the citations. Trends in the past five years included the use of terms such as acute ischemic stroke and mechanical thrombectomy. Conclusion The findings of this study provide novel insight into this field and will facilitate future research endeavors.

Abstract
Background and purposes Treating intracranial stenosis with distal thrombosis (IS&DT) using traditional mechanical thrombectomy (MT) techniques has proven challenging. This study aimed to summarize the experience of utilizing the balloon-assisted tracking (BAT) technique for IS&DT. Methods Demographic and morphologic characteristics of patients with IS&DT were collected for this study. The BAT technique, involving a half-deflated balloon outside the intermediate catheter tip, was used in all patients to navigate through the proximal stenosis. Various parameters were recorded, including the sequence of vascular reperfusion, the puncture-to-reperfusion time (PRT), the residual stenosis rate, and the occurrence of re-occlusion. The thrombolysis in cerebral infarction (TICI) scale was used to assess the reperfusion of intracranial vessels, with a TICI score of ≥2b considered as successful perfusion. The clinical status of patients was evaluated at three time points: pre-procedure, post-procedure, and at discharge using the modified Rankin score (mRS). Results In this study, a total of 10 patients were diagnosed with IS&DT, consisting of 9 male patients (90.0%) and 1 female patient (10.0%). The patients' mean age was 63.10 years (ranging from 29 to 79 years). The mean National Institute of Health Stroke Scale (NIHSS) score before treatment was 24.3 (ranging from 12 to 40), indicating the severity of their condition. Following the procedure, all patients achieved successful reperfusion with a thrombolysis in cerebral infarction (TICI) score of ≥2b. The average puncture-to-reperfusion time (PRT) was 51.8 min (ranging from 25 to 100 min), indicating the time taken for the procedure. During the perioperative period, three patients (30.0%) experienced complications. One patient had hemorrhage, while two patients had contrast extravasation. Among these cases, only the patient with hemorrhage (10%) suffered from a permanent neurological function deficit. At discharge, the patient's condition showed improvement. The mean NIHSS score decreased to 13.2 (ranging from 1 to 34), indicating a positive response to treatment. The mean mRS score at discharge was 3.2 (ranging from 1 to 5), showing some level of functional improvement. Conclusion In conclusion, the use of the balloon-assisted tracking (BAT) technique for treating intracranial stenosis with distal thrombosis (IS&DT) showed promising results. However, a moderate rate of perioperative complications was observed, warranting further investigation and refinement of the procedure.

Abstract
BACKGROUND It remains unclear whether bridging therapy can achieve better neurologic outcomes than direct endovascular thrombectomy (EVT) in patients with posterior ischemic stroke. METHODS We systematically searched PubMed, EMBASE, and Cochrane databases with posterior artery occlusion treated with bridging therapy vs. EVT. Efficacy was assessed based on functional independence at 90 days and successful recanalization, whereas safety was assessed by mortality, rate of symptomatic intracranial hemorrhage (sICH), and occurrence of any hemorrhage. All data were analyzed with Review Manager software v5.3 and the risk of bias was determined using the Methodological Index for Non-randomized Studies. RESULTS We included 17 studies with a total of 3278 patients (1211 in the bridging therapy group and 2067 in the EVT group). Patients in the bridging group had a better functional outcome at 90 days, as evidenced by a higher proportion with a Modified Rankin Scale (mRS) score of 0-2 compared with the EVT group (odds ratio (OR) = 1.83, 95% confidence interval (CI): 1.54-2.19, P < 0.01), while no difference in mRS score of 0-3 (OR = 1.18, 95% CI: 0.96-1.45, P = 0.11). Patients in the bridging therapy group also had lower 90-day mortality rate (OR = 0.75, 95% CI: 0.59-0.95, P = 0.02). There were no significant differences between groups in rates of successful recanalization (OR = 0.96, 95% CI: 0.74-1.25, P = 0.77), sICH (OR = 1.27, 95% CI: 0.86-1.89, P = 0.24), and hemorrhage (OR = 1.22, 95% CI: 0.60-2.50, P = 0.58). CONCLUSIONS Among patients with posterior ischemic stroke, bridging therapy may be superior to EVT in achieving a good functional outcome and lowering the mortality without increasing the risks of hemorrhage.

Abstract
OBJECTIVE This study aimed to summarize the clinical outcomes of endovascular treatment in patients with basilar artery occlusion (BAO) with different pathologic mechanisms. METHODS Two independent reviewers searched PubMed/MEDLINE, Embase and Cochrane Library database up to December 2022, patients with different BAO pathological mechanisms (BAO with in situ atherosclerosis vs. embolism alone without vertebral artery steno-occlusion vs. embolism from tandem vertebral artery steno-occlusion) were collected and analyzed. We calculated the odds ratios (ORs) and 95% confidence intervals (CIs) to assess the associations between clinical outcomes and BAO pathological mechanisms. RESULTS A total of 1163 participants from 12 studies were identified. Compared with embolism alone, patients with in situ atherosclerotic BAO had a lower favorable outcome rate (modified Rankin score [mRS] 0-2: 34.5% vs. 41.2%; OR 0.83, 95% CI 0.70-0.98; P = 0.03) and moderate outcome rate (mRS 0-3: 45.8% vs. 55.4%; OR 0.65, 95% CI 0.47-0.90; P = 0.01) at 3 months and a higher risk of mortality (29.9% vs. 27.2%; OR 1.31, 95% CI 0.96-1.79, P = 0.09; adjusted OR 1.46, 95% CI 1.08-1.96). Tandem BAO had a comparable mortality risk to that of in situ atherosclerotic BAO (OR 1.37, 95% CI 0.84-2.22; P = 0.48) or embolism alone (OR 1.44, 95% CI 0.65-3.21; P = 0.43), and there were no significant differences in favorable or moderate outcomes between tandem BAO and each of the other two BAO mechanisms. CONCLUSION Among BAO patients with endovascular treatment, embolism mechanism had better clinical outcomes than in situ atherosclerosis, and atherosclerotic mechanism was associated with a higher mortality at 3 months. RCTs are needed to further confirm clinical outcomes of BAO by different mechanisms.

Abstract
BACKGROUND The morphology of the basilar artery tip (BAT) varies between patients. The morphologic anatomy of the BAT could affect the efficacy of mechanical thrombectomy (MT). METHODS 108 patients with acute distal basilar artery occlusion (dBAO) who underwent MT from January 2013 to December 2021 were retrospectively analyzed. These patients were divided into two groups based on their BAT morphology: those with symmetrical cranial or caudal fusion of the BAT (symmetric group) and those with asymmetrical fusion of the BAT (asymmetric group). Morphological variables and angiographic and clinical outcomes were compared between the two groups. RESULTS Of the 108 enrolled patients, 42 were in the asymmetric group. Compared with the symmetric group, the asymmetric group had significantly larger BAT diameter (mean 3.5±1.0 mm vs 4.3±1.1 mm, P=0.001) and basilar artery tip/trunk ratio (1.2±0.2 vs 1.7±0.2, P<0.001). The asymmetric group showed a significantly lower rate of complete reperfusion (71.2% vs 40.5%, P=0.002) and first pass effect (FPE) (51.5% vs 21.4%, P=0.002) than the symmetric group. The BAT asymmetry was an independent predictor of failed FPE (OR 0.299, 95% CI 0.098 to 0.918, P=0.035) and failed complete reperfusion (OR 0.275, 95% CI 0.087 to 0.873, P=0.029). CONCLUSIONS The efficacy of MT for dBAO differs according to the anatomic morphology of the BAT. The asymmetric BAT was frequently encountered in dBAO patients and was independently associated with a reduced likelihood of complete reperfusion and FPE.

Abstract
Background and purpose Basilar-artery occlusion (BAO) usually accounts for devastating neurologic sequelae, poor prognosis, and even death. While endovascular thrombectomy (EVT) is the most successful treatment for anterior circulation stroke with large vessel occlusion, its effectiveness in treating acute BAO is still debatable. Our aim is to compare the efficacy and safety between EVT and conservative medical treatment (CMT) in BAO. Methods Up until May 2022, relevant literature was gathered using searches in Embase, PubMed, and the Cochrane Library. The primary outcomes were defined as good functional outcome (modified Rankin Scale 0-2) and favorable functional outcome (modified Rankin Scale 0-3) at 3 months between EVT and CMT groups. The secondary outcomes included mortality at 3 months, symptomatic intracerebral hemorrhage (ICH), and any ICH. Results Eight studies involving 3733 patients with BAO were enrolled 2573 individuals underwent EVT, and the remaining 1160 patients received CMT. Compared with CMT, EVT achieved more favorable functional outcome (odds ratio (OR) 1.26, 95% CI 1.03-1.55, I2 = 54%, p = 0.05) in BAO. The good functional outcome showed a similar tendency (OR 1.23, 95% CI 0.97-1.57, I2 = 63%, p = 0.02) as well. EVT decreased mortality at 3 months (OR 0.81, 95% CI 0.70-0.93, I2 = 31 %, p = 0.19), although having a tendency to cause symptomatic ICH (OR 2.91, 95% CI 1.38-6.18, I2 = 22 %, p = 0.27). Conclusions EVT in BAO provides superior functional outcomes and less mortality compared with CMT. Even though EVT has the propensity to cause symptomatic ICH, EVT nevertheless improved posterior circulation stroke.

Abstract
Ischemic stroke presents a major global economic and public health burden. Although recent advances in available endovascular therapies show improved functional outcome, a good number of stroke patients are either ineligible or do not have access to these treatments. Also, robust collateral flow during acute ischemic stroke independently predicts the success of endovascular therapies and the outcome of stroke. Hence, adjunctive therapies for cerebral blood flow (CBF) enhancement are urgently needed. A very clear overview of the pial collaterals and the role of genetics are presented in this review. We review available evidence and advancement for potential therapies aimed at improving CBF during acute ischemic stroke. We identified heme-free soluble guanylate cyclase activators; Sanguinate, remote ischemic perconditioning; Fasudil, S1P agonists; and stimulation of the sphenopalatine ganglion as promising potential CBF-enhancing therapeutics requiring further investigation. Additionally, we outline and discuss the critical steps required to advance research strategies for clinically translatable CBF-enhancing agents in the context of acute ischemic stroke models.

Abstract
Efficacy and safety of mechanical thrombectomy (MT) for stroke with posterior circulation large vessel occlusion (LVO) is still under debate. We aimed to compare the outcomes of stroke patients with posterior circulation LVO treated with intravenous thrombolysis (IVT) (< 4.5 h after symptom onset) plus MT < 6 h after symptom onset with those treated with IVT alone (< 4.5 h after symptom onset). Patients enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS) and in the Italian centers included in the SITS-ISTR were analysed. We identified 409 IRETAS patients treated with IVT plus MT and 384 SITS-ISTR patients treated with IVT alone. IVT plus MT was significantly associated with higher rate of sICH (ECASS II) compared with IVT alone (3.1 vs 1.9%; OR 3.984, 95% CI 1.014-15.815), while the two treatments did not differ significantly in 3-month mRS score ≤ 3 (64.3 vs 74.1%; OR 0.829, 95% CI 0.524-1.311). In 389 patients with isolated basilar artery (BA) occlusion, IVT plus MT was significantly associated with higher rate of any ICH compared with IVT alone (9.4 vs 7.4%; OR 4.131, 95% CI 1.215-14.040), while two treatments did not differ significantly in 3-month mRS score ≤ 3 and sICH per ECASS II definition. IVT plus MT was significantly associated with higher rate mRS score ≤ 2 (69.1 vs 52.1%; OR 2.692, 95% CI 1.064-6.811) and lower rate of death (13.8 vs 27.1%; OR 0.299, 95% CI 0.095-0.942) in patients with distal-segment BA occlusion, while two treatments did not differ significantly in 3-month mRS score ≤ 3 and sICH per ECASS II definition. IVT plus MT was significantly associated with lower rate of mRS score ≤ 3 (37.1 vs 53.3%; OR 0.137, 0.009-0.987), mRS score ≤ 1 (22.9 vs 53.3%; OR 0.066, 95% CI 0.006-0.764), mRS score ≤ 2 (34.3 vs 53.3%; OR 0.102, 95% CI 0.011-0.935), and higher rate of death (51.4 vs 40%; OR 16.244, 1.395-89.209) in patients with proximal-segment BA occlusion. Compared with IVT alone, IVT plus MT was significantly associated with higher rate of sICH per ECASS II definition in patients with stroke and posterior circulation LVO, while two treatment groups did not differ significantly in 3-month mRS score ≤ 3. IVT plus MT was associated with lower rate of mRS score ≤ 3 compared with IVT alone in patients with proximal-segment BA occlusion, whereas no significant difference was found between the two treatments in primary endpoints in patients isolated BA occlusion and in the other subgroups based on site occlusion.

Abstract
PURPOSE To illustrate the characteristics of acute ostial vertebral artery (VA) and basilar artery (BA) tandem occlusions. The endovascular treatment strategy for ostial VA-BA tandem occlusion was reported. MATERIALS AND METHODS We conducted a retrospective analysis of patients with ostial VA-BA tandem occlusion who underwent endovascular treatment in our center between November 2018 and February 2022. We preferred to recanalize the dominant vertebral artery with priority. The imaging characteristics, treatment strategy, clinical outcomes, and complications were analyzed. RESULTS In total, 9 patients with ostial VA-BA tandem occlusion were enrolled in this study. All the VA-BA tandem occlusion was caused by acute occlusion of the dominant VA. Endovascular revascularization was performed through the occluded dominant VA in 8 patients and was performed through contralateral non-dominant VA in 1 patient. Successful recanalization (mTICI 2b/3 grade) was achieved in all 9 patients, and 5 patients (55.5%) achieved functional independence with a mRS score of 0-2 at 90 days. CONCLUSIONS In this case series, the occurrence of ostial VA-BA tandem occlusions was mainly caused by acute occlusion of the dominant VA. Endovascular revascularization of ostial VA-BA tandem occlusions through occluded dominant VA was feasible and recommended.

Abstract
Objective The aim of this study was to examine the factors influencing the prognosis of patients diagnosed with acute basilar artery occlusion (BAO) who receive endovascular treatment. Our particular emphasis was on the predictive implications of the time window for treatment (from symptom onset to femoral artery puncture) and preoperative symptoms for prognosis. Methods A retrospective analysis of data collected from 51 BAO patients who received endovascular treatment at the Neurosurgery Department of Jinhua Central Hospital from April 2018 to October 2021 was undertaken. The data included immediate post-interventional recanalization rates and the 90-day clinical prognoses of the patients. We used the Modified Rankin Scale (mRs) to categorize patients into two prognosis groups: a favorable prognosis group (mRs score ≤2) and an unfavorable prognosis group (mRs score >2). Preoperative symptoms were gauged using the Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) scores. A logistic regression analysis was conducted to identify risk factors affecting the prognosis of BAO patients following endovascular treatment. Results The procedure resulted in complete recanalization in all patients (100%). However, four patients (7.8%) passed away during the postoperative hospitalization period. The remaining 47 patients were followed up for 3 months. It was found that 15 patients (31.91%) had a favorable prognosis, while 32 (68.09%) had an unfavorable prognosis. It was generally observed that patients with an unfavorable prognosis had notably higher preoperative GCS and NIHSS scores (p < 0.05). Logistic regression analysis revealed that preoperative symptom severity, as indicated by NIHSS score, and treatment time window were significant prognostic risk factors for patients undergoing endovascular treatment for BAO (p < 0.05). Conclusion Endovascular intervention for BAO appears to be safe and effective, with greater likelihood of a favorable prognosis in patients treated within ≤6 h. The chances of favorable prognosis could potentially be linked to the severity of the patient's preoperative symptoms.

Abstract
Posterior circulation infarcts comprise approximately 25% of ischemic strokes but are less often treated with recanalization therapy and have longer treatment delays compared with anterior circulation strokes. Among posterior circulation strokes, basilar artery occlusion is associated with the most severe deficits and the worst prognosis. Endovascular thrombectomy is a standard of care for patients with anterior circulation large vessel occlusion, but not until recently were the first randomized controlled trials on endovascular thrombectomy in basilar artery occlusion published. Two of the trials were neutral, whereas two others showed better functional outcome after thrombectomy up to 24 hours of symptom onset compared with best medical treatment, which in most cases had low rates of intravenous thrombolysis. According to observational data, thrombectomy seems to be safe also in isolated posterior cerebral artery occlusions and might be an option for selected patients, even if its outcome benefit is yet to be demonstrated.

Abstract
Background and purpose: To share our single-center vertebral artery stump syndrome (VASS) treatment experience and assess the role of comprehensive classification based on anatomic development, proximal conditions, and distal conditions (PAD). Materials and methods Data were retrospectively collected from patients who underwent endovascular thrombectomy (EVT) at the Stroke Center of the First Hospital of Jilin University between January 2016 and December 2021. Among patients with acute ischemic stroke in the posterior circulation, those with acute occlusion of the intracranial arteries and occlusion at the origin of the vertebral artery confirmed by digital subtraction angiography were selected. The clinical data were summarized and analyzed. Results Fifteen patients with VASS were enrolled in the study. The overall success rate of surgical recanalization was 80%. The successful proximal recanalization rate was 70.6%, and the recanalization rates for P1, P2, P3, and P4 were 100%, 71.4%, 50%, and 66.67%, respectively. The mean operation times for the A1 and A2 types were 124 and 120 min, respectively. The successful distal recanalization rate was 91.7%, and the recanalization rates for types D1, D2, D3, and D4 were 100%, 83.3%, 100%, and 100%, respectively. Five patients experienced perioperative complications (incidence rate: 33.3%). Distal embolism occurred in three patients (incidence rate: 20%). No dissection or subarachnoid hemorrhage occurred in any patient. Conclusion EVT is a technically feasible treatment for VASS, and comprehensive PAD classification can, to a certain extent, help initially estimate the difficulty of surgery and provide guidance for interventional procedures.

Negative susceptibility vessel sign might be predictive of complete reperfusion in patients with acute basilar artery occlusion managed with thrombectomy. Eur Radiol 2023; 33:2593-2604. [PMID: 36562785 DOI: 10.1007/s00330-022-09215-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 09/26/2022] [Accepted: 09/30/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVES Negative susceptibility vessel sign (SVS) on pre-thrombectomy MRI has been linked to fibrin-rich thrombus and difficult retrieval in anterior ischemic stroke. However, its impact in posterior circulation-large vessel occlusion stroke (PC-LVOS) has not yet been elucidated. We aim to investigate the relationship of SVS parameters with stroke subtypes and their influence on angiographic and functional outcomes. METHODS Prospective thrombectomy registries at two-comprehensive stroke centers were retrospectively reviewed between January 2015 and December 2019 for consecutive MRI-selected patients with PC-LVOS. Two groups were assigned by two independent readers, based on the presence or absence of the SVS (SVS +, SVS -) on MRI-GRE sequence. Multivariate logistic regression analysis was utilized to study primarily the impact of the SVS on the rate of complete recanalization (defined as mTICI 2c/3) at the final series following endovascular thrombectomy (EVT) and whether or not it might influence the efficacy of the frontline EVT strategy. Secondarily, we studied whether the absence of the SVS was predictive of the rate of 90-day functional independence (defined as mRS score < 2). Lastly, both qualitative (SVS +, SVS-) and quantitative (SVS length and diameter) parameters of the SVS were analyzed in association with the puncture to recanalization interval and various stroke etiological subtypes based on TOAST criteria. RESULTS Among 1823 patients, 116 were qualified for final analysis (median age, 68 (59-75) years; male, 65%); SVS was detected in 62.9% (73/116) of cases. SVS length was an independent predictor of procedural duration (p = .01) whilst two-layered SVS was inversely associated with the atherosclerosis etiological subtype (aOR = 0.27, 95% CI 0.08-0.89; p = .03). Successful recanalization was achieved in 82% (60/73) vs. 86% (37/43), p = .80 of patients with SVS (+, -) respectively. Only in SVS (+), stentriever (RR 0.59 (0.4-0.88), p = .009), and contact-aspiration (RR 0.82 (0.7-0.96), p = .01) achieved a lower rate of successful recanalization compared to combined technique. SVS (-) was significantly associated with a higher rate of mTICI 2c/3 (aOR = 4.444; 95% CI 1.466-13.473; p = .008) and showed an indirect effect of 9% towards functional independence mediated by mTICI 2c/3. CONCLUSION SVS parameters in PC-LVOS might predict stroke subtype and indirectly influence the functional outcome by virtue of complete recanalization. KEY POINTS • Negative susceptibility vessel sign (SVS) in patients with basilar occlusion independently predict complete recanalization that indirectly instigated a 3-month favorable outcome following thrombectomy. • The longer the SVS, the higher likelihood of large artery atherosclerosis and the longer the thrombectomy procedure. • Two-layered SVS might be negatively associated with the presence of atherosclerosis, yet already-known limitations of TOAST classification and the absence of pathological analysis should be taken into consideration.

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
In 1981, the dismal outcomes of patients with basilar artery occlusion (BAO) inspired the first reports of intra-arterial thrombolytic treatment in BAO. These reports were among the first to conceptualize that opening an artery could help patients with large vessel occlusion stroke. Whereas multiple anterior circulation LVO trials demonstrated the efficacy of endovascular therapy starting in 2014, proof of benefit for BAO was lacking until 2022. In this commentary, we reflect on how the BASICS (Basilar Artery International Cooperation Study) and BEST (Basilar Artery Occlusion: Endovascular Interventions vs Standard Medical Treatment) trials lay the foundations for clinical trials in BAO, subsequently leading to the positive results of the ATTENTION (Endovascular Treatment for Acute Basilar-Artery Occlusion) and BAOCHE (Basilar Artery Occlusion Chinese Endovascular) trials.

Abstract
Background Delayed reocclusion (DR) after successful recanalization in acute basilar artery occlusion (BAO) patients, which is associated with clinical deterioration and poor outcome, has not been well studied. The current study is aimed to predict DR after successful endovascular therapy in acute BAO patients. Method 187 consecutive patients presenting with acute BAO and undergoing endovascular treatment (EVT) were selected in Beijing Tiantan Hospital from January 2012 to July 2018. Computed tomographic angiography (CTA) or magnetic resonance angiography (MRA) within 7 days of the thrombectomy was used to identify reocclusion of the target vessel. Multivariable logistic regression analysis was used to evaluate associated factors and clinical impact. Results DR was observed in 17 of 169 successfully reperfused patients (10.1%). Patients with DR had higher frequency of intracranial atherosclerotic stenosis (ICAS) (94.1% vs. 61.8%; P = 0.01), higher frequency of intracranial angioplasty during EVT (88.2% vs. 57.2%; P = 0.02), lower frequency of stent-retriever use during EVT (52.9% vs. 78.9%; P = 0.03) and a lower proportion of modified Thrombolysis In Cerebral Infarction (mTICI) 3 reperfusion (41.2% vs. 78.3%; P < 0.01). Suggestive predictors were mTICI3 reperfusion (aOR, 0.205; 95% CI, 0.061-0.686) and stent-retriever using (aOR, 0.29; 95% CI, 0.086-0.980). DR was an independent predictor of unfavorable outcome at 90 days (aOR for mTICI ≤3, 5.205; 95% CI, 1.129-24.005). Conclusions DR within 7 days after successful mechanical thrombectomy in acute BAO patients is rare but associated with poor outcome. Patients without mTICI3 reperfusion and stent-retriever using are at high risk for DR.

Abstract
BACKGROUND To quantify the effectiveness and safety of the Trevo® Retriever for endovascular treatment of acute ischemic stroke (AIS) patients in China. METHODS Trevo Retriever Registry (China) was a prospective, multicenter, non-comparative, open-label study of patients with AIS treated with the Trevo Retriever. The primary outcome was the proportion of patients achieving an expanded Thrombolysis in Cerebral Infarction (eTICI) score ≥2b at the end of endovascular treatment. Secondary outcomes included first-pass eTICI score ≥2b and 90-day modified Rankin Scale (mRS) score ≤2. RESULTS The Trevo Retriever Registry (China) enrolled and followed 201 patients (62.1 ± 12.5 years-old; 70.6% male) at 11 centers. The pre-procedure NIHSS score and ASPECTS were 16 (interquartile range (IQR), 13-21) and 7 (IQR, 6-9), respectively, and 188 (93.5%) patients had an mRS score of 0 prior to the stroke. The main stroke etiology was large artery atherosclerosis, accounting for 71.6% (144/201) of patients. Post-procedure eTICI ≥2b was 98.4% (187/190). First-pass eTICI ≥2b was 74.7% (136/182). The 90-day good outcome (mRS ≤2) rate was 73.6% (148/201). The 90-day all-cause mortality was 5.5% (11/201). Neurological deterioration at 24 h post-procedure was observed in 7.7% (15/195) patients. Embolism in a new territory was seen in one patient (0.5%). Two (1.0%) procedure-related adverse events (AEs) occurred, which were intra-procedure cerebral artery embolism. No Trevo related AEs occurred. CONCLUSIONS This real-world study of the Trevo Retriever in China demonstrated a high rate of revascularization and first-pass success that resulted in an overall high good function outcome rate and low mortality.

Abstract
BACKGROUND Novel thrombectomy strategies emanate expeditiously day-by-day counting on access system, clot retriever device, proximity to and integration with the thrombus, and microcatheter disengagement. Nonetheless, the relationship between native thrombectomy strategies and revascularization success remains to be evaluated in basilar artery occlusion (BAO). PURPOSE To compare the safety and efficacy profile of key frontline thrombectomy strategies in BAO. METHODS Retrospective analyses of prospectively maintained stroke registries at two comprehensive stroke centers were performed between January 2015 and December 2019. Patients with BAO selected after MR imaging were categorized into three groups based on the frontline thrombectomy strategy (contact aspiration (CA), stent retriever (SR), or combined (SR+CA)). Patients who experienced failure of clot retrieval followed by an interchanging strategy were categorized as a fourth (switch) group. Clinicoradiological features and procedural variables were compared. The primary outcome measure was the rate of complete revascularization (modified Thrombolysis in Cerebral Infarction (mTICI) grade 2c-3). Favorable outcome was defined as a 90 day modified Rankin Scale score of 0-2. RESULTS Of 1823 patients, we included 128 (33 underwent CA, 35 SR, 35 SR +CA, and 25 switch techniques). Complete revascularization was achieved in 83/140 (59%) primarily analyzed patients. SR +CA was associated with higher odds of complete revascularization (adjusted OR 3.04, 95% CI 1.077 to 8.593, p=0.04) which was an independent predictor of favorable outcome (adjusted OR 2.73. 95% CI 1.152 to 6.458, p=0.02). No significant differences were observed for symptomatic intracranial hemorrhage, functional outcome, or mortality rate. CONCLUSION Among BAO patients, the combined technique effectively contributed to complete revascularization that showed a 90 day favorable outcome with an equivalent complication rate after thrombectomy.

Abstract
OBJECTIVE The aim of this study was to investigate the efficacy and safety of endovascular treatment (EVT) plus standard medical treatment (SMT) in patients with acute basilar artery occlusion (BAO) within 6 hours of the estimated occlusion time, based on a Chinese population. METHODS The authors selected patients from the Endovascular Treatment of Acute Basilar Artery Occlusion Study (BASILAR) registry, which was a nationwide prospective registry, within 6 hours after the estimated time of onset of a stroke in acute BAO. Patients were divided into the SMT-alone group or the EVT+SMT group according to treatment modalities. The primary outcome was a favorable functional outcome, defined as a modified Rankin Scale score between 0 and 3 at 90 days. Safety outcomes included death at 90 days and symptomatic intracerebral hemorrhage. RESULTS The authors assessed 590 patients for eligibility. Of these patients, 127 received SMT alone and 463 were treated with EVT plus SMT. EVT was associated with a higher rate of a favorable functional outcome (adjusted OR 3.804, 95% CI 1.890-7.658; p < 0.001) and a lower proportion of deaths at 90 days (adjusted OR 0.364, 95% CI 0.223-0.594; p < 0.001). Lower age (adjusted OR 0.978, 95% CI 0.960-0.997; p = 0.022); lower baseline National Institutes of Health Stroke Scale score (adjusted OR 0.926, 95% CI 0.902-0.950; p < 0.001); higher baseline posterior circulation Alberta Stroke Program Early CT Score (adjusted OR 1.681, 95% CI 1.424-1.984; p < 0.001); absence of diabetes mellitus (adjusted OR 0.482, 95% CI 0.267-0.871; p = 0.016); and modified Thrombolysis in Cerebral Infarction scores 2b-3 (adjusted OR 5.117, 95% CI 2.304-11.367; p < 0.001) were independent factors for a favorable outcome in the EVT+SMT group. CONCLUSIONS Based on the study design, patients with acute BAO who received EVT within 6 hours were associated with improved favorable outcome and decreased deaths compared with patients who received SMT. Predictors of desirable outcome in patients undergoing EVT included lower age, lower baseline National Institutes of Health Stroke Scale score, higher baseline posterior circulation Alberta Stroke Program Early CT Score, absence of diabetes mellitus, and modified Thrombolysis in Cerebral Infarction scores 2b-3.

Exact Basilar Artery Occlusion Location Indicates Stroke Etiology and Recanalization Success in Patients Eligible for Endovascular Stroke Treatment. Clin Neuroradiol 2022; 33:483-490.

Abstract
Abstract
Introduction
Endovascular stroke treatment (EST) is commonly performed for acute basilar artery occlusion (BAO). We aimed to identify the role of the exact location of BAO in patients receiving EST regarding the stroke etiology, recanalization success and prediction of favorable clinical outcome.
Methods
Retrospective analysis of 191 consecutive patients treated for BAO with EST from 01/2013 until 06/2021 in a tertiary stroke center. Groups were defined according to exact location of BAO in I: proximal third, II: middle third, III: distal third and IV: tip of the basilar artery. Univariate and multivariate analyses were performed for BAO location comparing stroke etiology, recanalization result and favorable clinical outcome according to mRS 0–3 90 days after stroke onset.
Results
Occlusion sides types I–IV were evenly distributed (37, 36, 60 and 58 patients). Types I and II were more often associated with large artery atherosclerosis (50 vs. 10 patients, p < 0.001). Distal/tip occlusion (types III/IV) occurred mostly in cardiac embolism or embolic stroke of unknown source (89 vs. 12 in types I/II, p < 0.001). Occlusion site correlated with the underlying stroke etiology (AUC [Area under the curve] 0.89, p < 0.0001, OR [odds ratio] for embolism in type IV: 245). Recanalization rates were higher in patients with distal occlusions (type III/IV OR 3.76, CI [95% confidence interval] 1.51–9.53, p = 0.0076). The BAO site is not predicting favorable clinical outcome.
Conclusion
The exact basilar artery occlusion site in patients eligible for endovascular stroke treatment reflects the stroke etiology and is associated with differing recanalization success but does not predict favorable clinical outcome.

Abstract
Acute ischemic stroke of the posterior circulation as a result of vertebrobasilar artery occlusions is often associated with severe morbidity and mortality rates. Vertebrobasilar artery occlusion retrieval via mechanical thrombectomy (MT) is a novel treatment modality for occlusive strokes. Nevertheless, factors associated with positive outcomes have not yet been adequately investigated. Thus, the present study focused on factors associated with good prognosis following this type of treatment. The present study retrospectively analyzed a series of 17 patients with acute vertebral artery occlusions (VAOs) and basilar artery occlusions (BAOs) treated with MT. In all patients, information such as sex and age, time from admission to the onset of femoral artery access, the number of thrombi removed, the time of femoral artery access to recanalization, pre- and post-operative National Institutes of Health Stroke Scale (NIHSS) scores, pre- and post-operative thrombolysis in cerebral infarction, as well as modified Rankin scale scores were documented and analyzed. The analysis comprised of 11 patients with BAOs and 6 patients with VAOs. A recanalization rate of 70.6% was achieved with an overall good functional outcome of 58.8% at 90 days. Observationally, there was a notable improvement in outcomes when comparing the NIHSS prior to surgery with NIHSS at 1 week after the surgery. A lower NIHSS score prior to MT may be a good prognostic factor. An average time of ~5.5 h from patient admittance to recanalization with a 70.6% recanalization rate with an overall good functional outcome of 58.8% at 90 days suggested that, patients for whom the surgeries were performed within 5 h of admittance may still have hope for recanalization compared to an initial 1.5-h average time for recanalization.

Outcomes Following Mechanical Thrombectomy in Different Etiological Subtypes of Acute Basilar Artery Occlusion : Stroke Etiology and Outcome after EVT in BAO. Clin Neuroradiol 2022; 33:361-374.

Abstract
BACKGROUND AND PURPOSE Vertebrobasilar occlusion stroke (VBOS) is innately associated with high morbimortality despite advances in endovascular thrombectomy (EVT). Nonetheless, notable outcome dissimilarities exist between angiographically categorized stroke subtypes. We aim to evaluate potential differences concerning clinical angiographic outcomes among etiological subtypes of VBOS based on the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria. METHODS We retrospectively reviewed prospective EVT databases at two tertiary care stroke centers for consecutive patients with VBOS who had preinterventional MRI and underwent EVT from January 2015 to December 2019. We identified three groups: large artery atherosclerosis (LAA), cardioembolic stroke (CES), and embolic stroke of undetermined source (ESUS). The primary endpoints were the rates of poor outcome (identified as 90-day modified Rankin scale score of 3-6) and mortality, while the secondary endpoint included the rates of incomplete reperfusion (identified as modified treatment in cerebral infarction scale mTICI 0-2b), and periprocedural symptomatic intracranial hemorrhage. We evaluated the association between the etiology and clinical angiographic outcomes through stepwise logistic regression analysis. RESULTS Out of 1823 patients, 139 (91 men; median age, 69 (61-76) years) with VBOS were qualified for the final analysis with incidence as follows: LAA (41%, n = 57), CES (35%, n = 48), and ESUS (24%, n = 34). Overall, incomplete reperfusion was realized in 41% (57/139) of the patients, a poor outcome in 65% (90/139), and mortality in 40% (55/139). Longer puncture to reperfusion interval (aOR 1.0182 [95% CI: 1.008-1.029]; p < 0.001) and utilization of combined aspiration-retriever technique (aOR 0.1998 [95% CI: 0.066-0.604]; p = 0.004) were associated with a greater likelihood of incomplete reperfusion (mTICI 0-2b) irrespective of the stroke etiology. After adjustment for confounding factors in the regression analysis, ESUS was an independent predictor of poor outcome (aOR 5.315 [95% CI: 1.646-17.163]; p = 0.005) and mortality (aOR 4.667 [95% CI: 1.883-11.564]; p < 0.001) at 90 days following EVT. CONCLUSION The functional outcome following EVT for VBOS might depend on stroke etiology. According to our results, ESUS seems to be associated with the worst outcome, which needs further investigation to tailor the appropriate therapeutic plan.

Abstract
Introduction Stroke etiology may affect the prognosis of acute basilar artery occlusion (BAO). This study aimed to estimate the efficacy and safety of endovascular treatment (EVT) in BAO strokes due to the underlying stroke etiologies of large artery atherosclerosis (LAA) and cardioembolism (CE). Patients and methods Patients with LAA and CE subtypes from the registry EVT for Acute Basilar Artery Occlusion Study (BASILAR) were selected for this analysis. We estimated the EVT treatment effect relative to standard medical treatment (SMT) in these patients by using a propensity score approach with inverse probability of treatment weighted estimation. Outcomes included 90-day favorable functional outcomes (modified Rankin scale (mRS) 0-3), functional independence (mRS 0-2), all-cause mortality, and symptomatic intracranial hemorrhage (sICH). Results A total of 744 patients were included in the final analysis. After weighting with inverse probability of treatment estimation, the patients who, based on their characteristics, were treated with EVT rather than SMT, demonstrated higher rates of favorable functional outcomes in both the LAA (29.2% vs 11.7%, adjusted OR with 95% CI: 4.34 [2.15-8.78], p < 0.001) and the CE subtype (36.0% vs 8.1%, adjusted OR with 95% CI: 9.14 [1.96-42.55], p = 0.005). A similar finding was also observed for functional independence. EVT patients also demonstrated lower rates of mortality than SMT. Among EVT patients, no significant difference was observed in mortality or sICH between LAA and CE groups, but LAA patients had lower rates of favorable functional outcome and functional independence (29.2% vs 37% and 24.2% vs 32.9%, respectively), where the latter remained significant after adjustment for imbalances in baseline data (p = 0.04). Conclusions In acute BAO strokes, both LAA and CE patients who, based on their characteristics, were treated with EVT rather than SMT, demonstrated better outcomes. Among EVT patients, LAA and CE subtypes displayed important baseline and treatment differences, and LAA patients were less likely to achieve functional independence at 3 months, but mortality and sICH were similar between LAA or CE subtypes. These results need to be confirmed in future clinical trials.

Abstract
BackgroundThis study aimed to investigate the clinical outcomes of endovascular treatment (EVT) for distal basilar artery occlusion (BAO) and compare them with the outcomes of standard medical treatment (SMT) in daily clinical practice.MethodsPatients with distal BAO enrolled in the BASILAR study from January 2014 to May 2019 were included. Differences in clinical outcomes were analyzed using Pearson's chi-square test and multivariable logistic regression. Clinical outcomes were evaluated using the modified Rankin Scale (mRS) score at 90 days, the mortality at 90 days, and the occurrence of symptomatic intracranial hemorrhage within 48 h.ResultsAmong the 267 patients with distal BAO (222 patients in the EVT group and 45 patients in the SMT group), compared with the SMT group, the EVT group was associated with a favorable outcome (mRS 0–3; 40.1 vs. 15.6%; aOR 5.44; 95% CI, 1.68–17.66; P = 0.005) and decreased mortality (44.6 vs. 71.1%, aOR 0.32, 95% CI, 0.13–0.77; P = 0.012). In the EVT group, multivariable analysis showed that the initial National Institutes of Health Stroke Scale (NIHSS) score and posterior circulation-Alberta Stroke Program Early CT Score (pc-ASPECTS) were associated with favorable functional outcomes and mortality.ConclusionOur study suggests that, compared with SMT, EVT is technically feasible and safe for patients with distal BAO.

CT Marker in Emergency Imaging of Acute Basilar Artery Occlusion: Thrombosis vs. Embolism. Diagnostics (Basel) 2022; 12:diagnostics12081817. [PMID: 36010168 PMCID: PMC9406658 DOI: 10.3390/diagnostics12081817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 07/23/2022] [Accepted: 07/25/2022] [Indexed: 12/02/2022] Open
Abstract
Purpose: Acute basilar artery occlusion, a neurovascular emergency leading to high rates of morbidity and mortality, is usually diagnosed by CT imaging. The outcome is partly dependent on etiology, with a worse outcome in occlusions with underlying basilar artery stenosis. As this occlusion type requires a more complex angiographic therapy, this study aimed to develop new CT markers in emergency admission imaging to rapidly identify underlying stenosis. Methods: A total of 213 consecutive patients (female n = 91, age in years (mean/SD/range): 72/13/28−97), who received endovascular treatment at a single comprehensive stroke center for acute basilar artery occlusion, were included in this study. After applying strict inclusion criteria for imaging analyses, novel CT imaging markers, such as ‘absolute density loss’ (ADL) and relative thrombus attenuation (CTA-index), that measure perviousness, were assessed for n = 109 patients by use of CT-angiography and correlated to different occlusion patterns (thrombotic vs. embolic). Inter-observer agreement was assessed using an intraclass correlation coefficient for independent measures of a radiologist and a neuroradiologist. Associations between the imaging markers and clinical and interventional parameters were tested. Results: CT markers differ between the subgroups of basilar artery occlusions with and without underlying stenosis (for ADL: 169 vs. 227 HU (p = 0.03), for CTA-index: 0.55 vs. 0.70 (p < 0.001)), indicating a higher perviousness in the case of stenosis. A good inter-rater agreement was observed for ADL and CTA-index measures (ICC 0.92/0.88). For the case of embolic occlusions, a more pervious thrombus correlates to shorter time intervals, longer procedure times, and worse reperfusion success (p-values < 0.05, respectively). Conclusions: ADL and CTA-index are easy to assess in the emergency setting of acute basilar artery occlusion with the use of routinely acquired CT-angiography. They show a high potential to differentiate thrombotic from embolic occlusions, with an impact on therapeutic decisions and angiographic procedures. Measurements can be quickly performed with good reliability, facilitating implementation in clinical practice.

Abstract
BACKGROUND The authors compare the effectiveness and safety of endovascular treatment (EVT) versus best medical management (BMM) in strokes attributable to acute basilar artery occlusion (BAO). METHODS The present analysis was based on the ongoing, prospective, multicenter ATTENTION (Endovascular Treatment for Acute Basilar Artery Occlusion) trial registry in China. Our analytic sample comprised 2134 patients recruited at 48 sites between 2017 and 2021 and included 462 patients who received BMM and 1672 patients who received EVT. We performed an inversed probability of treatment weighting analysis. Qualifying patients had to present within 24 hours of estimated BAO. The primary clinical outcome was favorable functional outcome (modified Rankin Scale score, 0-3) at 90 days. We also performed a sensitivity analysis with the propensity score matching-based and the instrumental variable-based analysis. RESULTS In our primary analysis using the inversed probability of treatment weighting-based analysis, there was a significantly higher rate of favorable outcome at 90 days among EVT patients compared with BMM-treated patients (adjusted relative risk, 1.42 [95% CI, 1.19-1.65]; absolute risk difference, 11.8% [95% CI, 6.9-16.7%]). The mortality was significantly lower (adjusted relative risk, 0.78 [95% CI, 0.69-0.88]; absolute risk difference, -10.3% [95% CI, -15.8 to -4.9]) in patients undergoing EVT. Results were generally consistent across the secondary end points. Similar associations were seen in the propensity score matching-based and instrumental variable-based analysis. CONCLUSION In this real-world study, EVT was associated with significantly better functional outcomes and survival at 90 days. Well-designed randomized studies comparing EVT with BMM in the acute BAO are needed. REGISTRATION URL: www.chictr.org.cn Unique identifier: ChiCTR2000041117.

J Stroke 2022; 24:245-255. [PMID: 35677979 PMCID: PMC9194548 DOI: 10.5853/jos.2022.01095] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 05/13/2022] [Indexed: 11/23/2022] Open
Abstract
Background and Purpose We investigated the impact of stroke etiology on the endovascular treatment (EVT) procedure and clinical outcome of posterior circulation stroke (PCS) patients with EVT compared to anterior circulation stroke (ACS) patients.
Methods We retrospectively analyzed ischemic stroke patients who underwent EVT between January 2012 and December 2020. Enrolled ACS and PCS patients were compared according to etiologies (intracranial arterial steno-occlusion [ICAS-O], artery-to-artery embolic occlusion [AT-O], and cardioembolic occlusion [CA-O]). EVT procedure and favorable clinical outcomes at 3 months (modified Rankin Scale 0–2) were compared between the ACS and PCS groups for each etiology.
Results We included 419 patients (ACS, 346; PCS, 73) including 88 ICAS-O (ACS, 67; PCS, 21), 66 AT-O (ACS, 50; PCS, 16), and 265 CA-O (ACS, 229; PCS, 36) patients in the study. The onset-to-recanalization time was longer in the PCS group than in the ACS group (median 628.0 minutes vs. 421.0 minutes, P=0.01). In CA-O patients, the door-to-puncture time was longer, whereas the puncture-to-recanalization time was shorter in the PCS group than in the ACS group. The proportions of successful recanalization and favorable clinical outcomes were similar between the ACS and PCS groups for all three etiologies. Low baseline National Institutes of Health Stroke Scale (NIHSS) scores and absence of intracerebral hemorrhage at follow-up imaging were associated with favorable clinical outcomes in both groups, whereas successful recanalization (odds ratio, 11.74; 95% confidence interval, 2.60 to 52.94; P=0.001) was only associated in the ACS group.
Conclusions The proportions of successful recanalization and favorable clinical outcomes were similar among all three etiologies between PCS and ACS patients who underwent EVT. Initial baseline NIHSS score and absence of hemorrhagic transformation were related to favorable outcomes in the PCS and ACS groups, whereas successful recanalization was related to favorable outcomes only in the ACS group.

Abstract
The efficacy of endovascular treatment (EVT) in patients with posterior circulation stroke has not been proven. Two recent randomized controlled trials failed to show improved functional outcomes after EVT for posterior circulation stroke (PC-EVT). However, promising results for two additional randomized controlled trials have also been presented at a recent conference. Studies have shown that patients undergoing PC-EVT had a higher rate of futile recanalization than those undergoing EVT for anterior circulation stroke. These findings call for further identification of prognostic factors beyond recanalization. The significance of baseline clinical severity, infarct volume, collaterals, time metrics, core-penumbra mismatch, and methods to accurately measure these parameters are discussed. Furthermore, their interplay on EVT outcomes and the potential to individualize patient selection for PC-EVT are reviewed. We also discuss technical considerations for improving the treatment efficacy of PC-EVT.

Abstract
BACKGROUND In patients with large vessel occlusion stroke of the anterior circulation, underlying cause is a determinant of outcome. Whether this is the case for posterior circulation large vessel occlusion stroke has yet to be determined. We aimed to report on cause in patients with posterior circulation stroke treated with endovascular thrombectomy and to analyze the association with functional outcome. METHODS We used data of patients with posterior circulation stroke included in the MR CLEAN (Multicenter Randomized Controlled Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands) registry, a prospective multicenter observational study, between 2014 and 2018. Stroke cause was categorized into large artery atherosclerosis (LAA), cardioembolism, arterial dissection, embolic stroke of undetermined source (ESUS), other determined cause, or undetermined cause. For primary analysis on the association between cause and outcome, we used multivariable ordinal logistic regression analysis to estimate the adjusted common odds ratio for a shift towards a better functional outcome on the modified Rankin Scale at 90 days with LAA as a reference group. Secondary outcomes included favorable functional outcome (modified Rankin Scale score 0-3), National Institutes of Health Stroke Scale score at 24 to 48 hours, reperfusion on digital subtraction angiography, and stroke progression. RESULTS Of 264 patients with posterior circulation stroke, 84 (32%) had LAA, 48 (18%) cardioembolism, 31 (12%) dissection, and 14 (5%) ESUS. Patients with a dissection were younger (48 [interquartile range, 43-60] years) and had a lower National Institutes of Health Stroke Scale at baseline (12 [interquartile range, 6-31]) than patients with other cause. Functional outcome was better for patients with cardioembolism and ESUS compared to LAA (modified Rankin Scale adjusted common odds ratio, 2.4 [95% CI, 1.1-5.2], respectively adjusted common odds ratio, 3.1 [95% CI, 1.0-9.3]). Patients with a dissection had a lower chance of successful reperfusion compared with LAA (adjusted odds ratio, 0.20 [95% CI, 0.06-0.70]). CONCLUSIONS Unlike the anterior circulation, most frequent cause in our posterior large vessel occlusion stroke cohort is LAA followed by cardioembolism, dissection, and ESUS. Patients with cardioembolism and ESUS have a better prognosis for functional outcome after endovascular thrombectomy than patients with LAA.

Abstract
Despite there being a robust amount of literature and numerous randomized clinical trials regarding acute ischemic stroke treatment, the trials have not included some frequent controversial situations for which decision-making strategies are an urgent and unmet need in clinical practice. This article tries to summarize the current evidence about some selected situations (mechanical thrombectomy in low ASPECTS, low NIHSS with proximal occlusion, acute basilar occlusion, distal and medium vessel occlusion, among others), make suggestions on how to approach them in clinical practice and show what to expect in acute stroke research in the near future.

Abstract
BACKGROUND Whether endovascular thrombectomy (EVT) is superior to standard medical treatment (SMT) for stroke patients with acute basilar artery occlusion (BAO) is uncertain. This systematic review and meta-analysis aimed to compare the safety and efficacy of EVT with SMT for treating BAO patients. METHODS Papers were retrieved from PubMed, Embase, and the Cochrane Library databases. The primary outcome of this meta-analysis was favorable functional outcomes at 3 months (defined as a modified Rankin Scale (mRS) score of ≤3). A random effect model was used to calculate risk ratios (RR) with 95% confidence intervals (CIs) per outcome. RESULTS Five articles, including two randomized controlled trials (RCTs) and four observational cohort studies, comprising 1484 patients (1024 in the EVT group and 460 in the SMT group), were included in the meta-analysis. The pooled results demonstrated no significant differences between the EVT and SMT groups in achieving favorable functional outcomes at 3 months (RR=1.63, 95% CI 0.90, 2.96; p=0.11). However, patients in the EVT group had higher rates for symptomatic intracerebral hemorrhage (RR=6.22, 95% CI 2.06 to 18.76; p=0.001) but lower mortality at 3 months (RR=0.72, 95% CI 0.56 to 0.91; p=0.007) than patients in the SMT group. CONCLUSION Among patients with BAO, EVT and SMT did not differ significantly in achieving favorable functional outcomes at 3 months, but BAO patients treated with EVT might have lower mortality at 3 months. RCTs are warranted to further assess the efficacy and safety of EVT for BAO patients.

Abstract
OBJECTIVES Our goal was to describe outcomes in a single-center, real-world series of patients with acute basilar artery occlusion in a middle-income country. In addition, we assessed potential outcome predictors. MATERIAL AND METHODS Data from 28 patients were retrospectively reviewed. The primary outcome was death until last follow-up. Other outcomes were rates of favorable outcome until last follow-up and rates of intracranial hemorrhage. Outcomes were compared in subgroups according to several variables, including reperfusion (REP group) or no reperfusion (NOREP group) interventions, with chi-squared, Fisher's exact test, or Mann-Whitney tests. RESULTS The rate of overall intrahospital death was 46%. Death until last follow-up occurred in 8/17 (47%) in the REP and in 7/11 (63%) of the NOREP group. Favorable outcomes were observed in 35.7% of the patients: 8/17 (47%) in REP and in 2/11 (18.1%) in NOREP. NIH stroke scale scores were significantly lower in patients with favorable outcomes. Intracranial hemorrhage was observed in 6/28 (21.4%) of the patients (all in REP group). Twenty patients were treated with anticoagulants within the first 24 h. No hemorrhage was observed in those treated with enoxaparin, while three occurred in subjects treated with unfractionated heparin. CONCLUSION Together with other series, our results underscore the relevance of NIH stroke scale at admission as a prognostic marker, the importance of reperfusion to improve outcomes, and the need of clinical trials to compare the impact of treatment with anticoagulants within first 24 h in basilar artery occlusion.

Endovascular Thrombectomy for Acute Basilar Artery Occlusion: Latest Findings and Critical Thinking on Future Study Design. Transl Stroke Res 2022; 13:913-922. [PMID: 35349051 DOI: 10.1007/s12975-022-01008-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 03/11/2022] [Accepted: 03/14/2022] [Indexed: 10/18/2022]
Abstract
Randomized controlled trials (RCTs) have demonstrated powerful efficacy of endovascular thrombectomy (EVT) for large vessel occlusion in the anterior circulation. The effect of EVT for acute basilar artery occlusion (BAO) in the posterior circulation remains unproven. Here, we highlight the latest findings of observational studies and RCTs of EVT for BAO, with a focus on the predictors of functional outcomes, the limitations of recent RCTs, and critical thinking on future study design. Pooled data from large retrospective studies showed 36.4% favorable outcome at 3 months and 4.6% symptomatic intracranial hemorrhage (sICH). Multivariate logistic regression analysis revealed that higher baseline NIHSS score, pc-ASPECTS < 8, extensive baseline infarction, large pontine infarct, and sICH were independent predictors of poor outcome. Two recent randomized trial BEST (Endovascular treatment vs. standard medical treatment for vertebrobasilar artery occlusion) and BASICS (Basilar Artery International Cooperation Study) failed to demonstrate significant benefit of EVT within 6 or 8 h after stroke symptom onset. The limitations of these studies include slow enrollment, selection bias, high crossover rate, and inclusion of patients with mild deficit. To improve enrollment and minimize risk of diluting the overall treatment effect, futile recanalization and re-occlusion, optimal inclusion/exclusion criteria, including enrollment within 24 h of last known well, NIHSS score ≥ 10, pc-ASPECTS ≥ 8, no large pontine infarct, and the use of rescue therapy for underlying atherosclerotic stenosis, should be considered for future clinical trials.

A comparison between acute large vessel occlusion in the posterior circulation and anterior circulation after endovascular treatment: the ANGEL-ACT registry experience. Stroke Vasc Neurol 2022; 7:285-293. [PMID: 35260439 PMCID: PMC9453828 DOI: 10.1136/svn-2021-001093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Accepted: 11/02/2021] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND AND PURPOSE Endovascular treatment (EVT) has shown an overwhelming benefit for acute anterior circulation artery occlusion (ACO). Whether it can achieve the same outcomes in posterior circulation artery occlusion (PCO) has not been well explained. We aimed to evaluate the characteristics and prognosis of ACO and PCO after EVT in a nationwide registry. METHOD The present analysis was based on the prospective ANGEL-ACT Registry in China between November 2017 and March 2019. Demographic data, periprocedural times, recanalisation rate, intracranial haemorrhage (ICH) and 90-day functional outcomes were compared between the ACO and PCO groups. RESULTS A total of 1793 patients were analysed including 397 (22.1%) consecutive patients with PCO and 1396 (77.9%) patients with ACO treated with EVT. A larger proportion of patients with PCO had intracranial atherosclerotic disease and received extra angioplasty during EVT. Successful recanalisation and 90-day favourable functional outcomes did not differ significantly between the two groups. Patients with PCO showed lower 24-hour ICH and symptomatic ICH rates. There was a trend towards higher mortality rate in the PCO group (22.09% vs 14.44%; adjusted OR 1.286 (95% CI 0.820 to 2.017), p=0.2731), especially when the onset to puncture time was over 6 hours (30.77% vs 11.13%; adjusted OR 2.673 (95% CI 1.280 to 5.583), p=0.0089, interactive p=0.0002). CONCLUSIONS In this large prospective multicentre registry, there was a significant difference in the characteristics and periprocedural features between patients with PCO and ACO. However, successful recanalisation and 90-day favourable functional outcomes in PCO were equivalent to those in ACO.

The Safety and Efficacy of Endovascular Treatment in Acute Ischemic Stroke Patients Caused by Large-Vessel Occlusion with Different Etiologies of Stroke: Data from ANGEL-ACT Registry. Neurotherapeutics 2022; 19:501-512. [PMID: 35243592 PMCID: PMC9226213 DOI: 10.1007/s13311-022-01189-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/13/2022] [Indexed: 11/25/2022] Open
Abstract
This study aimed to investigate the safety and efficacy of endovascular treatment (EVT) in acute ischemic stroke (AIS) patients caused by large-vessel occlusion (LVO) with different etiologies of stroke. A total of 928 AIS patients were assigned into intracranial atherosclerotic stenosis (ICAS)-LVO, cardioembolic (CE)-LVO, and artery to artery embolism (ATA)-LVO groups. The safety and efficacy endpoints were symptomatic intracranial hemorrhage (SICH) at 24 h after EVT, 90-day favorable outcomes (modified Rankin Scale (mRS) of 0-2), successful recanalization (modified thrombolysis in cerebral infarct (mTICI) 2b/3), and complete recanalization (mTICI 3). The logistic regression analysis was used to determine the associations between the safety and efficacy endpoints. There were 305 (32.9%), 535 (57.6%), and 88 (9.5%) patients in ICAS-LVO, CE-LVO, and ATA-LVO groups, respectively. No significant difference was found in the 90-day mRS and successful recanalization among the three groups. However, compared with the ICAS-LVO group, complete recanalization rate was higher in the CE-LVO (adjusted odds ratio, 4.50; 95% confidence interval (CI), 2.37-8.56) and ATA-LVO groups (aOR, 2.43; 95% CI, 1.16-5.10). The results of subgroup analysis showed a significant association between CE-LVO stroke etiology and complete recanalization in the age population < 65 years old (aOR, 14.33; 95% CI, 4.39-46.79, P = 0.019). Functional outcomes were similar among different etiologies of stroke. CE-LVO and ATA-LVO could be related to a higher rate of complete recanalization, and there was a trend of the increased risk of parenchymal hemorrhage in the CE-LVO group.

Abstract
PURPOSE To investigate the difference in mechanical thrombectomy (MT) outcomes between vertebrobasilar tandem occlusion (VBTO) and isolated basilar artery (BA) occlusion (non-VBTO) and the difference in rates of successful recanalization between the clean-road and dirty-road pathways, in VBTO. METHODS We conducted a meta-analysis after searching PubMed, EMBASE, and Google Scholar databases as of April 2021. We only included adult patients who underwent MT to treat acute ischemic stroke (AIS) due to VBTO, and the following outcomes should be reported: successful recanalization, functional outcome at 90 days, and symptomatic intracerebral hemorrhage (sICH). The main effect size measures were odds ratio and risk difference, and the software used was RevMan 5.4. RESULTS The analysis included 81 VBTO and 324 non-VBTO patients (seven studies). We found no significant difference regarding 3 m functional independence [4 studies: OR = 1.71 (95% CI, 0.54, 5.43), I2 = 75%], 3 m mortality [4 studies: OR = 1.62 (95% CI, 0.62, 4.25), I2 = 66%], sICH [4 studies: OR = 1.71 (95% CI, 0.67, 4.39), I2 = 0%], and successful recanalization [3 studies: OR = 0.81 (95% CI, 0.12, 5.57), I2 = 80%]. A subgroup analysis of 118 VBTO patients (five studies) showed no significant difference in successful recanalization between clean-road and dirty-road pathways [RD = 0.07 (95% CI, - 0.09, 0.24), I2 = 40%]. CONCLUSION The results of this meta-analysis support the use of MT for AIS patients with VBTO. In VBTO patients, none of the clean-road or dirty-road pathways proved to be superior to the other.

Abstract
PURPOSE To evaluate the safety and efficacy of endovascular treatment (EVT) for patients with acute ischemic stroke (AIS) due to intracranial atherosclerosis-related basilar artery occlusion (ICAS-related BAO) by comparison with embolic and tandem occlusion. METHODS We retrospectively reviewed consecutive patients with AIS due to BAO who underwent EVT. Patients were assigned to the ICAS-related group and embolic group, and tandem group based on the etiology. Baseline data, procedural details, and clinical outcomes were compared between the three groups. RESULTS A total of 100 patients (ICAS-related group: 31; embolic group: 41; tandem group: 28) were included. No significant difference was observed in the successful reperfusion (mTICI 2b or 3), but the procedural time differed significantly (60 min vs. 43 min vs. 60 min, P = 0.010). There were no differences in the different intracranial hemorrhage grades among the three groups (P = 0.134). After adjusting for baseline differences, there was no significant difference in pairwise comparisons regarding favorable outcome (mRS 0-2), moderate outcome (mRS 0-3), and mortality. CONCLUSIONS Endovascular treatment for patients with acute ICAS-related BAO had equal efficacy and safety compared with embolic BAO and tandem BAO. Primary endovascular treatment and rescue modalities were effective treatments for acute ICAS-related BAO.

Abstract
Background and Purpose: The objective of this study was to identify prognostic factors of endovascular treatment in patients with acute basilar artery occlusion and add evidence about the efficacy and safety of endovascular treatment for acute basilar artery occlusion. Materials and Methods: We reviewed the data of 101 patients with acute basilar artery occlusion receiving endovascular treatment from January 2013 to September 2019. Baseline characteristics and outcomes were evaluated. A favourable functional outcome was defined as a mRS of 0 to 2 assessed at the 3 month follow-up. The association of clinical and procedural characteristics with the functional outcome and mortality was assessed. Results: The study population consisted of 101 patients: 83 males and 18 females. Successful recanalization was achieved in 99 patients (97.1%). A favourable clinical outcome was observed in 50 patients (49.5%), and the overall mortality rate was 26.7%. A favourable outcome was significantly associated with NIHSS score at admission and lung infection. Mortality was associated with NIHSS score at admission, the number of thrombectomy device passes, the postoperative pons-midbrain index, and diabetes mellitus. Conclusions: This study suggested that NIHSS score at admission, the number of thrombectomy device passes, the postoperative pons-midbrain index, diabetes mellitus, and lung infection can predict the functional outcome and mortality. These initial results add evidence about the efficacy and safety of endovascular treatment for acute basilar artery occlusion and need to be confirmed by further prospective studies.
