短暂性脑缺血发作患者ABCD2评分与颅内动脉狭窄的相关性研究

目的探讨短暂性脑缺血发作(TIA)患者ABCD2评分与颅内动脉狭窄的关系。方法选取2010年8月—2013年5月我院收治的行经颅多普勒(TCD)超声检查的TIA患者75例,根据ABCD2评分将患者分为低危组(16例)、中危组(37例)、高危组(22例)。分析3组患者颅内动脉狭窄的发生情况。结果高危组颅内动脉狭窄发生率为86.4%(19/22),中危组颅内动脉狭窄发生率为40.5%(15/37),低危组颅内动脉狭窄发生率为31.2%(5/16)。高危组颅内动脉狭窄发生率高于低、中危组(P0.05)。39例颅内动脉狭窄的TIA患者中,颅内受累血管为大脑中动脉25例(64.1%),颈内动脉颅内段10例(25.6%)。结论 ABCD2评分≥6分时颅内动脉狭窄发生率增高,可能是高危TIA患者进展为脑梗死的原因之一。

Correlation between ABCD2 Score and Intracranial Artery Stenosis on Patients with Transient Ischemic Attack

Objective To explore the relationship between ABCD2 score and intracranial artery stenosis on patients with transient ischemic attack（ TIA）. Methods 75 patients with TIA examined by transcranial doppler（ TCD） ultrasonography admitted to our hospital from August 2010 to May 2013 were divided into groups low- risk（ 16 cases）,risk（ 37 cases）, high- risk（ 22 cases）. The occurrence of intracranial artery stenosis among 3 groups were analyzed. Results The incidence of intracranial artery stenosis of high- risk group was 86. 4%（ 19 /22）,risk group was 40. 5%（ 15 /37）,low- risk group was 31. 2%（ 5 /16）. The incidence of intracranial artery stenosis in high- risk group was higher than that of low- risk and risk group（ P〈0. 05）. Intracranial vascular involvement of the middle cerebral artery were 25 cases（ 64. 1%）,intracranial segment of the internal carotid artery were 10 cases（ 25. 6%）. Conclusion The incidence of intracranial artery stenosis increases when ABCD2 score≥6 points,which may be one of reasons why patients have high risk of developing cerebral infarction.
