Abstract

Cerebral revascularization surgery is an important surgical option for unclippable cerebral aneurysm and prevention of the cerebral ischemia. During the past 10 years, we have performed cerebral revascularization for a variety of diseases on 257 cases. Among these cases, there were several cases of surgical complications. In adult moyamoya disease, rebleeding after surgery was seen approximately 15% in 10 years experience. High flow bypass from the external carotid artery to the middle cerebral artery was mainly performed to the unclippable carotid artery aneurysm for 56 cases. Among them, acute occlusion of the bypass was seen in three cases. Cerebral infarction occurred in one case. High flow bypass through the aorta to the occluded common carotid artery was performed in three cases of aortitis syndrome. Among them, hyperperfusion syndrome was observed in one case. In this paper, representative cases of surgical pitfalls of cerebral revascularization are demonstrated. The technical points for the prevention of these complications are discussed.
