CT血管造影侧支循环评分与缺血性脑卒中预后的研究进展

Research progress on collateral circulation scores of CT angiography and prognosis of ischemic stroke

机体在大脑供血动脉严重狭窄或闭塞时,良好的侧支循环可有效改善患者预后。研究显示基于CT血管造影(CT angiography,CTA)能够无创且直观地评价病变血管狭窄程度和侧支血流情况,快速精准的CTA侧支循环评分对临床决策和判断缺血性脑卒中预后有着重要意义。目前基于CTA侧支循环的评分量表较多,该文将对现有的7种CTA侧支循环评分量表的标准、临床应用优缺点及预测预后的相关研究进展进行综述,旨在为临床医生根据不同情况选择侧支循环评分量表、最佳治疗方案提供参考。

Good collateral circulation can effectively improve the prognosis of patients with severe stenosis or occlusion of cerebral blood supply artery.Studies have shown that CT angiography(CTA)can non-invasively and intuitively evaluate the degree of stenosis and collateral blood flow in diseased vessels.Rapid and accurate CTA collateral circulation score is of great significance for clinical decision-making and judging the prognosis of ischemic stroke.At present,there are many scoring scales based on CTA collateral circulation.This article will review the existing 7 CTA collateral circulation scoring scales,the advantages and disadvantages of clinical application and related research progress in predicting prognosis,aiming to provide a reference for clinicians to choose the collateral circulation score scale and the best treatment plan according to different situations.
