ReviewImaging after direct and indirect extracranial-intracranial bypass surgery.
The purpose of this article is to describe the imaging features of different types of surgical cerebral revascularization techniques. ⋯ Surgical cerebral revascularization involves direct and indirect techniques. Direct revascularization entails anastomosing a branch of the external carotid artery to a cerebral artery. Indirect revascularization involves delivering an extracranial vascular supply in proximity to the surface of the brain. The results of these techniques have distinctive imaging features.
