Techniques of End-To-Side Anastomosis—Experimental Evaluation and Clinical Findings
The degree of improvement of cerebral function after the extracranial-intracranial (EC/IC) bypass procedure depends on many factors: preoperative cerebral function, cerebral perfusion as indicated by angiography and CBF measurements, and quality of available extra-and intracranial vessels. Besides these given factors which influence the indication for an EC/IC bypass, another major factor is the surgical technique used to perform the EC/IC anastomosis. Yasargil3 developed a technique that has been applied—with minor changes in more than 4000 patients over the past 10 years. A major objection to this technique has been the fact that the recipient cerebral artery must be occluded with temporary clips over some 20–30 minutes.
