Sedation Versus General Anesthesia for Endovascular Therapy in Acute Stroke - Impact on Neurological Outcome

Summary

The purpose of this study is to evaluate whether general anesthesia or sedation technique is preferable during embolectomy for stroke, measured in terms of three months neurological impairment. In addition we study if there is any difference between the methods regarding complication frequency.
