ABSTRACT
Objective To evaluate the effect of anesthesia selection on endovascular treatment for anterior circulation major vessel occlusion stroke. Methods The clinical data of patients undergoing endovascular treatment in our hospital from January 2016 to August 2016 were retrospectively reviewed. The patients were divided into general anesthesia group and conscious sedation group. Comparison of the differences in time, symptomatic intracranial hemorrhage, and 90-day functional outcome between the two groups was made. Results A total of 73 patients were included in the analysis, 34 (46.6％) in the general anesthesia group, and 39 (53.4％) in the conscious sedation group. The baseline clinical data were balanced in both groups. There was no statistically significant difference in door-to-puncture time, puncture-to-recanalization time and onset-to-recanalization time between the two groups. The postoperative systolic blood pressure was significantly decreased in the general anesthesia group ((126.29 ± 20.07) vs (139.95 ± 21.22) mmHg (1 mmHg=0.133 kPa), t=2.81, P=0.01), whereas the rate of successful reperfusion (modified thrombolysis in cerebral infarction ≥ 2b) (94.1％(32/34) vs 87.2％(34/39), χ2=0.33, P=0.57), symptomatic intracranial hemorrhage rate (17.6％(6/34) vs 10.3％(4/39), χ2=0.33, P=0.57) and good outcome (modified Rankin Scale (mRS) score≤2) at 90 days (41.2％(14/34) vs 53.8％(21/39),χ2=1.17, P=0.28) did not show statistically significant difference between the two groups. Conclusions The selection of general anesthesia or conscious sedation had no significant effect on the outcome of endovascular treatment for anterior circulation major vascular occlusion stroke. The results of the study still need to be verified by large-scale randomized controlled trial.
