摘要
目的探讨短暂性脑缺血发作（transient ischemic attack，TIA）患者ABCD2评分和脑动脉狭窄的关系。方法回顾性分析了68例TIA患者ABCD2评分和颅脑磁共振血管成像（magnetic resonance angiographv，MRA）的影像资料，依据ABCD!评分分为≥4分组和≤3分组，依据MRA评估分为动脉狭窄≥50％组和〈50％组，探讨ABCD2评分与脑动脉狭窄的相关性。结果ABCD2评分分为≥4分组和≤3分组比较，动脉狭窄≥50％的比率增高（73_3％VS42．1％，p〈0．005）；既往有卒中、高血压、冠心病、高脂血症、糖尿病病史的患者比率增高（p〈0．05）；ABCD2评分分为≥4分组和≤3分组比较，TIA后7天内卒中发生率增高（13．3％vs2．63％，P〈0．05）。结论ABCD2评分≥4分的TIA患者MRA显示颅内动脉狭窄率高，且在TIA后7天内发生卒中的风险增高。
Objective To determine the relationship between ABCD2 score and cerebral artery stenosis of patients with transient ischemic attack（TIA）. Methods We retrospectively reviewed medical records of 68 patients with TIA; all of them were examined with the magnetic resonance angiography（MRA）.All patients were divided into two groups according to ABCD2 score 〉14 point or not, and cerebral artery stenosis ≥50% or not. The relationship between ABCD2 score and cerebral artery stenosis was analyzed. Results Group ABCD2 score ≥4 point were more likely to have cerebra/artery stenosis ≥50% compared with group ABCD2 score ≤3 point（73.3% vs 42.1%,p 〈0.005 ） . Group ABCD2 score≥4 point were more likely to have stroke history, hypertension, diabetes and hyperlipemia than those score ≤3 point （p 〈0.05 ） .The stroke within 7 days after TIA is higher in group ABCD2 score ≥4 point than that in group ABCD2 score ≤3 point （13.3% vs 2.63%,p 〈0.05 ） . Conclusion The patients with ABCD2 score 〉14 point show higher rate of cerebral artery stenosis. The stroke within 7 days after TIA is higher in patients with ABCD2 score ≥4 point.
