Abstract

Extracranial to intracranial (EC-IC) bypass surgery can be applied to achieve revascularization of the brain in patients in whom the normal pathway of blood flow to the brain is obstructed. Patients who may benefit from revascularization can be divided into two main groups. The first group consists of patients with a giant aneurysm of one of the cerebral arteries, which can not be clipped or coiled and for whom temporary or permanent occlusion of the artery is the only treatment option. The second group comprises patients with recurrent transient ischaemic attacks (TIAs) and stroke associated with occlusion of the internal carotid artery (ICA) at high risk of recurrent ischaemic stroke. The treatment with EC-IC bypass is based on the notion that in some patients with ICA occlusion ischaemic stroke is caused by failure of blood flow towards the brain rather than by embolism [36]. In such “haemodynamically compromised” patients augmentation of blood flow towards the symptomatic hemisphere by means of an EC-IC bypass might theoretically be beneficial.
