The purpose of this study was to assess the safety and efficacy, and to investigate the predictors for good and poor outcomes of thrombectomy for treatment of ais due to anterior circulation large vessel occlusions (lvos) in brazil.This was a single center registry of thrombectomy in the treatment of stroke caused by anterior circulation lvos.Between 2011 and 2019, a total of 565 patients were included, 297 male and 268 female, average age was 66.9 years.The mean baseline nihss score on admission was 17.2.The average baseline aspects was 8, and 91.0% of patients scored greater than or equal to 6.Half of the patients received intravenous thrombolysis.The mean time from symptom onset to arterial puncture was 296.4 minutes.The mean procedure time was 61.4 minutes.The rates of the main outcomes were recanalization (tici 2b-3) 85.6%, symptomatic intracranial hemorrhage (sich) 8,1%, good clinical outcome (mrs¼0-2) 43.5%, and mortality 22.1% at three months.This study demonstrates the efficacy and safety of mechanical thrombectomy for tr eatment of patients with ais of the anterior circulation in real-life conditions under limited facilities and resources.The results of the present study were relatively similar to those of large trials and population registers of developed countries. the article does not state any technical issues during use of the solitaire ab, solitaire fr, solitaire platinum and cello 8f/9f devices.
