Stroke
Conditions
Brief summary
The purpose of this clinical trial is to evaluate the efficacy and safety of combined recanalization therapy in patients who cannot be recanalized by acute large vessel occlusive stroke. The main questions it aims to answer are: 1、Proportion of subjects with mRs score of 0-1 at 90 days after surgery Participants will: 1、In acute large vessel occlusive stroke, if traditional means cannot be recanalized, combined recanalization surgery (including arteriotomy and thrombectomy, cerebrovascular bypass surgery) is performed.
