Complications of Cerebral Revascularization with Autogenous Vein Grafts

Abstract

Abstract Autogenous veins were used for cerebral revascularization 29 times. There were 17 long grafts to the cortex and 12 shorter grafts for reconstruction of cervical vessels. Of the long cortical grafts, 5 occluded and 3 patients developed intracerebral hemorrhage. With the shorter grafts, all remained patent and there were no hemorrhagic complications. A combination of a relatively low flow rate and endothelial damage in the graft was thought to be largely responsible for early graft failure. Revascularization of an infarct and hypertension were implicated in cases with intracerebral hemorrhage.
