Abstract

Since the first innovative surgical procedures of Extracranial-Intracranial Arterial Bypass(EIAB) were successfully carried out in 1967 by Drs. Yasargil and Donaghy , there has been a growing interest in this procedure. Over three thousand operations have been performed world-wide. There arc basically two indications for such a procedure. The first is for occlusive cerebrovascular diseases. The second is for establishing a prophylactic collateral blood supply in order to allow safe occlusion of a major intracranial vessel necessary for the surgical management of some giant aneurysms. In selected cases of occlusive cerebroyascular disease, the EIAB procedures can ameriolate transient ischemic attacks as well as reverse some neurologic deficits. However , the selection of patients of surgical management still remains controversial. Indications generally agreed upon are patients with TIA or RIND whose angiograms demonstrate a stenotic or occlusive lesion anatomically appropriate to the clinical symptoms and not treatable with standard surgical procedures. In this report the author described his experience of 5 cases with EIAB and discussed the criteria for patient selection and operative technique as well as long term results.
