title: Place of the extra-intra-cranial-bypass in aneurysm-surgery.
abstract: Before the use of the EC/IC-bypass, despite several tests to predict complications, ligation of the i.c.a. (e.g. in treatment of an unclippable aneurysm) offered a significant risk of cerebral ischemia, either acutely or on long term. In this article the hemodynamic background of the EC/IC-bypass as well as its probable effect on local cerebral blood flow are discussed. Next, a series of 26 patients is presented in which ligation of the i.c.a or the m.c.a. was considered. To prevent cerebral ischemia, first an EC/IC-bypass was established. After all, in 15 patients ligation of the i.c.a. was necessary. Beside one major complication the other complications after ligation were only minor and temporary.
