短暂性脑缺血发作患者ABCD^2评分与脑动脉狭窄关系的研究

Relationship between cerebral artery stenosis and ABCD^2 score in patients with transient ischemic attack

目的探讨短暂性脑缺血发作(TIA)患者ABCD2评分与脑动脉狭窄的关系。方法将71例TIA患者根据ABCD2评分分为低危组(15例)、中危组(32例)、高危组(24例)3组,行全脑血管造影(DSA)检查并将脑动脉狭窄程度分为轻度狭窄(狭窄<50%);中度狭窄(狭窄50%~69%);重度狭窄(狭窄70%~100%)。分析3组患者ABCD2评分与脑动脉狭窄严重程度及动脉狭窄范围的关系。结果高危组患者重度脑动脉狭窄的比例高于低、中危组(P<0.01);出现多支脑动脉狭窄的比例高于低危组(P<0.05)。结论 ABCD2评分≥6分时重度脑动脉狭窄和多支动脉狭窄的发生率增高,可能是高危TIA患者短期脑卒中风险增加的原因之一。

Objective To explore relationship between ABCD2 score and cerebral artery stenosis in patients with transient ischemic attack（TIA）.Methods 71 cases of TIA performed DSA were divided into 3 groups according to ABCD2 score：low score group（Score 1-3,n=15）,moderate score group（Score 4-5,n=32） and high score group（Score 6-7,n=24）.The relationgship between ABCD2 score and the severity of cerebral artery stenosis was analysed.Results Patients in high score group were more likely to have severe cerebral artery stenosis compared with low and morderate group（P0.01）,and also had more mutiple angiostenosis than low score group（P0.05）.Conclusions When ABCD2 score ≥6,The patients will have severe and multiple cerebral artery stenosis and this may be the reason why these patients have high risk of short-term stroke.
