Background and Objective: The effect of atrial fibrillation (AF) on outcomes of endovascular treatment (EVT) for acute ischemic stroke (AIS) is controversial. This study aimed to investigate the association of AF with outcomes after EVT in AIS patients.Methods: Subjects were selected from ANGEL-ACT registry (Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke) - a prospective consecutive cohort of AIS patients undergoing EVT at 111 hospitals in China between November 2017 and March 2019, and then grouped according to having a history of AF or not. After 1:1 propensity score matching, the outcome measures including the 90-day modified Rankin Scale (mRS) score, successful recanalization after final attempt, symptomatic intracranial hemorrhage (ICH) within 24 h, and death within 90 days were compared.Results: A total of 1755 patients, 550 with AF and 1205 without AF, were included. Among 407 pairs of patients identified after matching, no significant differences were found in the mRS score (median: 3 vs. 3 points; P = 0.29), successful recanalization (87.2 vs. 85.3%; P = 0.42), symptomatic ICH (9. 4 vs. 9.1%; P = 0.86) and death (16.3 vs. 18.4%; P = 0.44) between patients with and without AF.Conclusion: The findings of this matched-control study show comparable outcomes of EVT in Chinese AIS patients with and without AF, which do not support withholding EVT in patients with both AIS and AF.Trial Registration: NCT03370939 First registration date: 28/09/2017 First posted date: 13/12/2017.

Background: 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 the 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.
