改良ABCD^2评分与前循环短暂性脑缺血发作患者脑血管狭窄相关性研究

Relationship between Improved ABCD^2 Scores and Cerebral Artery Stenosis in Patients with Transient Ischemic Attack of Anterior Circulation

目的探讨前循环短暂性脑缺血发作患者改良ABCD2评分与脑血管狭窄的相关性。方法回顾性分析接受全脑血管造影的64例前循环TIA患者,根据改良ABCD2评分分为低危组(19例)、中危组(25例)、高危组(21例),分析患者脑血管形态学特点与各组的相关性。结果高危组患者中,重度狭窄及闭塞患者比例明显高于低危组及中危组,差异有统计学意义(P<0.05);高危组患者出现多支脑血管狭窄的比例高于低危组及中危组,差异有统计学意义(P<0.05);但各组患者血管狭窄的分布部位差异无统计学意义(P>0.05)。结论前循环TIA的患者随改良ABCD2评分的增加,脑血管狭窄程度及出现多支血管狭窄的发生率呈上升趋势。

Objective To investigate the correlation between the improved ABCD2 score and cerebral artery stenosis in patients with transient ischemic attack （TIA）. Methods Retrospective analysis of 65 patients with atherosclemtic TIA in anterior circulation who accept digital subtraction angiography （DSA） check were evaluated with improved ABCD2 system. The patients were divided into 3 groups according to the improved ABCD= scores：low risk group （score 1-3 ,n=19）, moderate risk group （score 4-5 ,n=25）and high risk group （score 6-8, n=21 ）. The relationship between the characteristics of cerebral artery and the score levels was analyzed. Results In the high risk group, the proportion of patients having sever stenosis and occlusion of vascular was greater than the low and morderate risk group （P〈0.05）. Patients in the high rick group were more likely to have muhi-vessel stenosis than the low risk and moderate risk group （P〈0.05）. The distribution of stenosis was not significantly different among the three groups （P〉0.05）. Conclusions Carotid artery TIA patients with improved ABCD2 had an improved score.The extent of cerebral artery stenosis and the incidence of multi-vessel stenosis were also increased.
