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 investigate the relationship between ABCD2 score and cerebral artery stenosis in patients with transient ischemic attack (TIA). Methods Seventy-one patients with TIA were divided into low-risk group (15 cases), middle-risk group (32 cases) and high-risk group (24 cases) according to ABCD2 score. Cerebral angiography (DSA) Degree is divided into mild stenosis (stenosis <50%); moderate stenosis (stenosis 50% to 69%); severe stenosis (stenosis 70% to 100%). The relationship between ABCD2 score and the severity of cerebral artery stenosis and the scope of artery stenosis were analyzed. Results The proportion of severe cerebral artery stenosis in high risk group was higher than that in low and intermediate risk group (P <0.01). The incidence of multiple cerebral artery stenosis was higher than that in low risk group (P <0.05). Conclusions The incidence of severe cerebral artery stenosis and multiple stenosis increased with ABCD2 score≥6, which may be one of the reasons for the increased risk of short-term stroke in high-risk TIA patients.
