Recent advance in relation between collateral circulation and prognoses of ischemic stroke based on multimodal imaging evaluation

Abstract

Cerebral collateral circulation can improve cerebral blood flow and protect neurons in ischemic stroke, which provides valuable time for reperfusion therapy and is closely related to the prognoses of patients with acute ischemic stroke. With the continuous emergence and development of new techniques for vascular reperfusion therapy in acute phase, it is urgent to establish a scheme for individualized evaluation of collateral circulation to guide clinical decision-making. Collateral circulation based on multi-mode imaging evaluation can provide guidance for clinical individualized diagnoses and accurate treatments more quickly and effectively to improve the clinical prognoses of patients. In order to provide guidance for the reperfusion treatment of acute ischemic stroke and effectively evaluate the clinical prognoses of patients, the authors summarize the research progress on correlation between collateral circulation and prognoses of ischemic stroke based on multi-mode imaging evaluation in recent years.
