摘要
急性缺血性脑卒中(acute ischemic stroke,AIS)发病率的逐年攀升,已是威胁人类健康,阻碍社会经济发展的重大疾病之一。高复发率、致残率及致死率无疑对人类生活质量及社会功能造成严重影响。多项研究表明,急性缺血性脑卒中后侧支循环的建立与临床的预后有明显相关性。因此,不少国内外学者正致力于研究多种成像技术对侧支循环的评估作用,并根据不同影像学侧支循环评分判断疾病的可能预后状况。目前针对侧支循环的形成机制、影像评估与临床预后的相关性学者们提出的观点仍存在差异性,本文将针对脑侧支循环的概念、形成原因、分级以及不同影像学技术进行综述。
As the incidence of acute ischemic stroke(AIS) increases year after year, it became one of the most serious diseases that threaten human health and hinder social even economic development. High recurrence rate, disability rate and mortality rate undoubtedly have a bad impact on human quality of life and social function. A number of studies have shown that the establishment of collateral circulation after acute ischemic stroke has a significant correlation with clinical prognosis. Therefore, many domestic and foreign scholars are working on the evaluation of collateral circulation by various imaging techniques and judging the possible prognosis of the disease according to different imaging collateral circulation scores. At present, there are still differences in the viewpoints of the formation mechanism, imaging evaluation and clinical prognosis of collateral circulation, this article will review the concept, cause, grading, and different imaging techniques of the collateral circulation.
