Background and Purpose: Clinical trials showed that anesthesia may not influence the functional outcome in stroke patients with endovascular therapy; however, data are lacking in China. Using real-world registry data, our study aims to compare the effects of general anesthesia or conscious sedation on functional outcomes in stroke patients treated with thrombectomy in China. Methods: Consecutive patients with acute anterior circulation stroke receiving thrombectomy in 21 stroke centers between January 2014 and June 2016 were included in this study. The propensity score analysis with 1: 1 ratio was used to match the baseline variables between patients with general anesthesia and the conscious sedation. The 90-day modified Rankin Scale (mRS), symptomatic intracranial hemorrhage (sICH), and death were compared between groups. Results: Of the 698 patients undergoing endovascular treatment, 138 were treated with general anesthesia and 560 with conscious sedation. After propensity score matching, 114 general anesthesia and 114 conscious sedation patients were matched. The proportions of patients with 90-day mRS 0–2 were not significantly different between general anesthesia and conscious sedation groups (41.2% [47/114] vs. 46.5% [53/114], p = 0.470), nor were the rates of sICH (21.9% [25/114] vs. 12.3% [14/114], p = 0.072) and 90-day mortality (31.6% [36/114] vs. 21.9% [25/114], p = 0.145). Conclusion: Anesthesia patterns may have no significant impacts on clinical outcomes in patients with acute anterior circulation occlusion stroke undergoing endovascular treatment in the real-world practice in China.
