EC-IC By-pass Surgery for Occlusive Cerebrovascular Lesion

Abstract

Since the first STA-MCA anastomosis was performed by Yasargil in 1967, extra-intracranial by-pass surgery is widely used for treatment of occlusive cerebrovascular lesions.
In our 171 STA-MCA anastomoses, there is no recurrence of TIA in 93.5% of TIA or RIND patients.
The indication, the technical aspect and the follow up study of this procedure have been reported.
The advantage and the limitation of EC-IC bypass have been discussed with the clinical recording of pre-, intra- and postoperative CBF measurement and computerized EEG monitoring.
The results of the OA-PICA anastomosis for vertebral occlusion and the STA-MCA anastomosis for Moya-Moya disease have been reported.
