目的探讨颈内动脉系统短暂性脑缺血发作(TIA)患者ABCD2评分和脑动脉狭窄程度与近期预后的关系。方法对89例颈内动脉系TIA患者进行ABCD2评分及数字减影血管造影(DSA),并分析其与近期预后的关系。结果依据ABCD2评分分为低危组28例、中危组35例、高危组26例三组。DSA检查显示,脑动脉中度狭窄25例(28.1%)、重度狭窄30例(33.7%)。高危组重度脑动脉狭窄的比例高于中危及低危组(P<0.05)。中重度脑动脉狭窄中高危组脑动脉狭窄的支数比例高于低危组(P<0.05)。30 d时发生脑梗死三组比较,高危组高于低危组(P<0.05)。结论颈内动脉系统TIA患者ABCD2评分和脑动脉狭窄程度对TIA的近期预后有重要的临床意义。
Objective To investigate the relationship between ABCD2 score, cerebral stenosis and the short-term prognosis in patients with internal carotid artery transient ischemic attack (TIA). Methods Eighty-nine patients with TIA in internal carotid artery were evaluated with ABCD2 score and digital subtraction angiography (DSA), and their relationship with the prognosis was analyzed. According to ABCD2 score, the results were divided into low risk group (28 cases), intermediate risk group (35 cases) and high risk group (26 cases). DSA examination showed moderate stenosis of cerebral artery in 25 cases (28.1%) and severe stenosis in 30 cases (33.7%). The proportion of severe cerebral artery stenosis in high risk group was higher than that in middle risk and low risk group (P <0.05). The proportion of cerebral arterial stenosis in moderate-severe cerebral artery stenosis was higher than that in low-risk group (P <0.05). Compared with the low-risk group (P <0.05), the high-risk group showed cerebral infarction at 30 days. Conclusion The ABCD2 score and the degree of cerebral artery stenosis in TIA patients with internal carotid artery have important clinical significance in the short-term prognosis of TIA.
