椎动脉优势对后循环短暂脑缺血发作患者近期预后的评价分析

摘要

Objective To research the recent prognosis of vertebral artery dominance in patients with posterior circula-tion transient ischemic attack. Methods All 120 patients were diagnosed with posterior circulation transient ischemic attack from January 2012 to October 2013 hospitalization, collected the vertebral artery MRA, clinical data ABCD2 score, the incidence of cerebral infarction within 7 days with the patients, and compared the differences. Results The share of vertebral artery dominance was higher than non-vertebral artery dominance in the posterior circulation TIA. According to ABCD2 score stratification, the incidence of cerebral infarction was rising from low-risk group to the risk group to the high-risk group. 7 days after TIA, the incidence of cerebral infarction in group with the vertebral artery dominant compared with the non-vertebral artery dominance had significant difference (P<0.05). If ABCD2 score<4 points, there was no significant difference in incidence of cerebral infarction between the group with vertebral artery dominant and non-vertebral artery dominance (P>0.05). If ABCD2≥ four points, the result was opposite (P<0.05). Conclusion The vertebral artery dominance is one of the risk factors for cerebral infarction to the patient with posterior circulation TIA. ABCD2 score in the high-risk patients'risk of vertebral artery advantage is particularly evident.%目的：研究椎动脉优势对后循环短暂脑缺血发作患者近期预后的影响。方法以2012年1月~2013年10月住院治疗被确诊为后循环短暂性脑缺血发作(transient ischemic attack，TIA)的患者120例为研究对象，收集其椎动脉MRA、临床资料ABCD2评分及7 d内脑梗死发生率，比较其差异性。结果后循环TIA中椎动脉优势占有率高于非椎动脉优势；ABCD2评分分层院从低危组到中危组到高危组脑梗死发生率呈上升趋势；TIA后7 d内脑梗死发生率椎动脉优势组较非椎动脉优势组有显著性差异(孕<0.05)；ABCD2评分<4分，脑梗死发生率椎动脉优势组与非椎动脉优势组比较，无显著性差异(P>0.05)；ABCD2评分≥4分，脑梗死发生率椎动脉优势组较非椎动脉优势组有显著性差异(P<0.05)。结论椎动脉优势为导致后循环TIA后脑梗死的危险因素之一；ABCD2评分中高危患者椎动脉优势的风险尤为明显。
