AbstractThere is continued controversy regarding the optimal anesthetic technique for endovascular therapy in patients with acute posterior circulation ischemic stroke. To compare the clinical outcomes general anesthesia (GA) and non-GA, we performed a systematic review and meta-analysis of randomized controlled trials and observational studies focused on the anesthetic management for endovascular therapy in patients with acute posterior circulation stroke, without language restriction. In addition, we compared clinical outcomes among the studies with different non-GA types (conscious sedation or local anesthesia). Outcome variables were functional independence, excellent outcomes, favorable outcomes, mortality, successful recanalization, hemodynamic instability, intracerebral hemorrhage, and respiratory or vascular complications. Eight studies including 1777 patients were identified. Although GA was associated with a lower odds of functional independence at 90 days (odds ratio [OR]: 0.55; 95% confidence interval [CI] 0.38 to 0.81; P =0.009), substantial heterogeneity was noted ( I2 =65%). Subgroup analysis showed that GA was associated with higher odds of mortality than conscious sedation (OR: 1.83; 95% CI, 1.30 to 2.57; I2 =0%), but there was no difference between GA and local anesthesia ( I2 =0%). Interestingly, subgroup analysis did not identify a relationship between functional independence and GA compared with local anesthesia (OR: 0.90; 95% CI, 0.64 to 1.25; P =0.919; I2 =0%). This meta-analysis demonstrates that GA is associated with worse outcomes in patients with acute posterior circulation stroke undergoing endovascular therapy based on current studies.Copyright © 2022 Wolters Kluwer Health, Inc.
