Objectives: To describe the clinical and epidemiological characteristics of patients with basilar artery occlusion (BAO) treated with mechanical thrombectomy (MT) in Aragón, and to compare its anaesthetic management, technical effectivity, security, and prognosis with those of anterior circulation. Methods: 322 patients from the prospective registry of mechanical thrombectomies from Aragon were assessed: 29 with BAO and 293 with an anterior circulation large vessel occlusion. Baseline characteristics, procedural, clinical and safety outcomes variables were compared. Results: Out of 29 patients with BAO that underwent endovascular therapy (62.1% men; average age 69.8 ± 14.05 years) 18 (62.1%) received endovascular therapy (EVT) alone and 11 (37.9%) EVT plus intravenous thrombolysis. Atherothrombotic stroke was the most common etiology (41%). The BAO group had longer Door-to-groin (160 vs 141 min; P = 0.043) and Onset-to-reperfusion times (340 vs 297 min; P = 0.005), and higher use of general anaesthesia (60.7% vs 14.7%; P < 0.01). No statistically significant difference was found for Procedure time (60 vs 50 min; P = 0.231) nor the rate of successful recanalization (72.4% vs 82.7%; P = 0.171). Functional independence at 90 days was significantly worse in the BAO group (17.9% vs 38.2%; P < 0.01). Conclusions: Patients with basilar artery occlusion had higher morbimortality despite similar angiographic results. Mechanical thrombectomy for BAOs is a safe and effective procedure in selected patients. A consensus about the effect of anaesthesia has yet to be reached, for BAO general anaesthesia remains the most frequently used technique.

BackgroundPerforming mechanical thrombectomy (MT) in patients with basilar artery occlusion (BAO) is currently not evidence-based.ObjectiveTo compare patients’ outcome, relative merits of achieving recanalization, and predictors of futile recanalization (FR) between BAO and anterior circulation large vessel occlusion (ACLVO) MT.MethodsIn the multicenter BEYOND-SWIFT registry (NCT03496064), univariate and multivariate (displayed as adjusted Odds Ratios, aOR and 95% confidence intervals, 95%-CI) outcome comparisons between BAO (N=165) and ACLVO (N=1574) were performed. The primary outcome was favorable outcome at 90 days (modified Rankin Scale, mRS 0-2). Secondary outcome included mortality, symptomatic intracranial hemorrhage (sICH) and FR. The relative merits of achieving successful recanalization between ACLVO and BAO were evaluated with interaction terms.ResultsMT in BAO was more often technically effective and equally safe in regards to mortality and sICH when compared to ACLVO. When adjusting for baseline differences, there was no significant difference between BAO vs ACLVO regarding rates of favorable outcome (aOR 0.986, 95%-CI 0.553 – 1.758). However, BAO were associated with increased rates of FR (aOR 2.146, 95%-CI 1.267 – 3.633). Predictors for FR were age, stroke severity, maneuver count and intracranial stenting. No significant heterogeneity on the relative merits of achieving successful recanalization on several outcome parameters were observed when comparing BAO and ACLVO.ConclusionsIn selected patients, similar outcomes can be achieved in BAO and ACLVO patients treated with MT. Randomized controlled trials comparing patient selection and interventional strategies seem warranted to avoid FR.Trial registration numberNCT03496064

Abstract Background and purpose: Endovascular treatment (EVT) is now considered the gold standard for select patient populations with anterior circulation stroke; however, data on the treatment of posterior circulation stroke are less clear. This study aims to determine the characteristics and treatment outcomes of patients with acute basilar artery occlusion (BAO) and to evaluate the effectiveness and safety of EVT for patients with acute BAO in a high-volume stroke center. Methods: This study included 187 consecutive patients with acute BAO who underwent EVT from January 2012 to July 2018 in Beijing Tiantan Hospital. The baseline characteristics, procedure parameters, and functional outcome were assessed. Results: Among the 187 patients, 138 (73.8%) underwent mechanical thrombectomy with a stent retriever, 33 (17.6%) underwent direct intracranial angioplasty (balloon dilation and/or stent implantation) for underlying severe intracranial atherosclerotic disease, and 91 (48.7%) underwent combined mechanical thrombectomy and angioplasty. Successful recanalization [modified Thrombolysis in Cerebral Infarction (mTICI) grade 2b-3] was achieved in 158 patients (84.5%). Overall, the rates of functional independence [modified Rankin Scale (mRS) 0-2] and favorable outcome (mRS 0-3) at 90 days were 36.4% and 49.2%, respectively, and 90- day all-cause mortality was 20.3%. Conclusion􀀌􀀁EVT was effective and safe for treating patients with acute BAO.

Abstract BACKGROUND Acute basilar artery occlusion causes devastating strokes that carry high mortality and morbidity. OBJECTIVE To report the outcomes of mechanical thrombectomy in the posterior circulation with a focus on safety and efficacy of stent retrievers. METHODS We retrospectively reviewed our endovascular database for all patients treated with stent retrievers for posterior circulation stroke between June 2012 and June 2014. Twelve patients were identified. The following data were analyzed: thrombus location, previous stroke or transient ischemic attack, thrombus etiology, comorbidities, time from presentation to initiation of endovascular treatment, time from start of angiography to revascularization, and whether intravenous tissue plasminogen activator was administered pre-thrombectomy. Outcome was considered poor when modified Rankin Scale score was &gt;2. RESULTS Mean patient age was 63.42 years (median, 64.5; range, 28-83 years); 7 were women. Successful recanalization (Thrombolysis in Cerebral Infarction grade 2b or 3) was achieved in 11 of 12 patients (91.7%). Mean discharge modified Rankin Scale score was 2.3 (median, 2.0; standard deviation 1.96; range, 0-6), with a favorable discharge outcome in 9 of 12 (75%) patients. Two patients died as inpatients. Mean follow-up modified Rankin Scale score was 1.4 (median, 1.00; standard deviation 1.075; range, 0-4). Good outcome was achieved in 9 of 10 (90%) patients at last follow-up (mean follow-up duration, 132.42 days [median, 90.50; standard deviation 80.2; range, 8-378 days]). CONCLUSION Our single-institution study has shown that good clinical outcomes and successful recanalization with acceptable mortality can be achieved with current stent retrievers.

BackgroundThe best anesthetic management strategy for patients with acute large vessel occlusion treated with mechanical thrombectomy (MT) remains uncertain. Most studies have focused on anterior–circulation stroke caused by large artery occlusion. Nevertheless, limited data are available on the appropriate choice of anesthetic for acute basilar artery occlusion (BAO). We aimed to investigate the effect of anesthetic method on clinical outcomes in patients with BAO undergoing MT.MethodsPatients undergoing MT for acute BAO in the BASILAR registry (Acute Basilar Artery Occlusion Study) were included. We divided patients into three groups according to the anesthetic technique used during MT: general anesthesia (GA), local anesthesia (LA), and conscious sedation (CS). Propensity score matching was performed to achieve baseline balance.Results639 patients were included. GA was used in 257 patients (40.2%), LA was used in 250 patients (39.1%), and CS was used in 132 patients (20.7%). After 1:1 matching, favorable outcome, mortality, and hemorrhagic transformation rates, as well as modified Rankin Scale (mRS) score at 90 days, did not differ between the GA, LA, and CS groups.ConclusionsThe choice of anesthetic strategy, GA, LA, or CS, did not affect the clinical outcomes of patients with acute BAO treated with MT in the BASILAR registry.

Rationale There are no randomized trials examining the best treatment for acute basilar artery occlusion in the 6–24-hour time window. Aims To assess the safety and efficacy of thrombectomy for stroke due to basilar artery occlusion in patients randomized within 6–24 h from symptom onset or time last seen well. Sample size For an estimated difference of 20% in proportions of the primary outcome between the two groups, 318 patients will be included for 5% significance and 90% power with a planned interim analysis after two-thirds of the sample size (212 patients) have achieved the 90 days follow-up. Methods and design A prospective, multi-center, randomized, controlled, open-label and blinded-endpoint trial. The randomization employs a 1:1 ratio of mechanical thrombectomy with the detachable Solitaire thrombectomy device and best medical therapy (BMT) vs. BMT alone. Study outcomes The primary outcome will be the proportion of patients achieving modified Rankin Scale (mRS) 0–3 at 90 days. Key secondary outcomes are: dramatic early favorable response, dichotomized mRS score (0–2 vs. 3–6 and 0–4 vs. 5–6) at 90 days, ordinal (shift) mRS analysis at 90 days, infarct volume at 24 h, vessel recanalization at 24 h in both treatment arms, and successful recanalization in the thrombectomy arm according to the modified thrombolysis in cerebral infarction (mTICI) classification defined as mTICI 2 b or 3. Safety variables are mortality at 90 days, symptomatic intracranial hemorrhage rates at 24 h, and procedure-related complications. Discussion Results from this trial will indicate whether mechanical thrombectomy is superior to medical management alone in achieving favorable outcomes in subjects with acute stroke caused by basilar artery occlusion presenting within 6–24 h from symptom onset.

Background and Purpose: In the settings of thrombectomy, the first-pass effect (FPE), defined by a complete recanalization after one pass with no rescue therapy, has been shown to be associated with an improved outcome. As this phenomenon has been predominantly described in anterior circulation strokes, we aimed to study the prevalence, outcomes, and predictors of FPE in patients with a basilar artery occlusion. Methods: From a prospective multicentric registry, we collected the data of all consecutive basilar artery occlusion patients who underwent thrombectomy and compared the outcomes of patients who achieved FPE and those who did not. We also compared FPE patients with those who achieved a complete recanalization with >1 pass. Finally, a multivariate analysis was performed to determine the predictors of FPE. Results: Data from 280 patients were analyzed in our study, including 84 of 280 patients (30%) with an atheromatous etiology. An FPE was achieved in 93 patients (33.2%), with a significantly higher proportion of good outcomes (modified Rankin Scale score 0-2 at 3 months) and lower mortality than non-FPE patients. An FPE was also associated with improved outcomes compared with patients who went on to have full recanalization with >1 pass. Contact aspiration as first-line strategy was a strong predictor of FPE, whereas baseline antiplatelets and atheromatous etiology were negative predictors. Conclusions: In our study, an FPE was achieved in approximately one-third of patients with a basilar artery occlusion and was associated with improved outcomes. More research is needed to improve devices and techniques to increase the incidence of FPE. Registration: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT03776877.
