Abstract
The purpose of this study is to consider the surgical indication for STA-MCA anastomosis from the preoperative angiographic point of view, and to find what kind of the preoperative angiographic findings bring a good blood flow through the anastomotic artery.
29 patent cases of STA-MCA anastomosis were used for the material of this study. The results were as follows
1. The large diameter of the STA brought a good anastomotic blood flow.
2. Delayed filling of the MCA via collateral circulation and/or back flow brought a good anastomosis blood flow too.
3. Although, it was thought the surgical indication was controversial in a case of completed stroke from the clinical point of view, the surgical indication might be accepted from the angiographic aspect even in a case of completed stroke.
