Advances on the application research of cerebral collateral circulation assessment for acute ischemic stroke mechanical thrombectomy

Abstract

The key to determine the survival time of ischemic penumbra in patients with acute ischemic stroke is the blood supply of collateral artery. The status of cerebral collateral circulation is closely related to the development of acute ischemic stroke, the recanalization rate of endovascular treatment and the clinical prognosis. This article mainly summarizes the types, characteristics, imaging assessment method of cerebral collateral circulation and its application in emergency mechanical thrombectomy of acute ischemic stroke.
