摘　　要：目的探讨后循环脑梗死患者血管病变的特点。方法收集2012年1月-2013年7月在中国中医科学院西苑医院神经内科住院的缺血性脑血管病患者245例。通过螺旋CT血管造影（CTA）对比87例后循环脑梗死患者及158例后循环无脑梗死患者的后循环动脉病变差异,分析后循环脑梗死患者血管病变部位、狭窄程度及形态特点。结果在后循环脑梗死患者中,椎动脉中、重度狭窄及闭塞的血管数多于基底动脉和大脑后动脉,差异有高度统计学意义（P〈0.01）。在椎动脉硬化狭窄病变中,起始段及颅内段占82.18%。后循环脑梗死患者中、重度狭窄及闭塞的动脉数明显多于后循环无脑梗死患者,差异有高度统计学意义（P〈0.01）。后循环梗死患者椎动脉发育不良率明显高于后循环无脑梗死患者,差异有高度统计学意义（P〈0.01）。结论后循环脑梗死患者主要血管病变为动脉粥样硬化狭窄,以椎动脉起始段及颅内段最常见。椎动脉发育不良是后循环脑梗死的危险因素。Objective To explore the features of vascular lesions in patients with posterior circulation cerebral infarction. Methods The image data of 245 patients with ischemic cerebrovascular diseases admitted to Xiyuan Hospital of China Academy of Chinese Medical Sciences from January 2012 to July 2013 were retrospectively studied. The difference of posterior circulation vascular lesions between 87 patients with posterior circulation cerebral infarction and 158 patients without posterior circulation cerebral infarction detected by CT angiography was compared. The location, stenosis and morphological characteristics of the vascular lesions in patients with posterior circulation cerebral infarction were analyzed. Results The proportion of severe stenosis and occlusion of vertebral artery was higher than that of posterior cerebral artery and basilar artery in patients with posterior circulation cerebral infarction, the difference was statistically significant（P〈0.01）. The initial and intracranial segment of vertebral artery stenosis was 82.18%. The proportion of severe stenosis and occlusion in patients with posterior circulation cerebral infarction was higher than that in patients without posterior circulation cerebral infarction, the difference was statistically significant（P〈0.01）. The vertebral artery hypoplasia was more frequent in posterior circulation cerebral infarction group than that in patients without posterior circulation cerebral infarction, the difference was statistically significant（P〈0.01）. Conclusion The major vascular lesions is atherosclerotic stenosis in patients with posterior circulation cerebral infarction, and the initial and intracranial segment of vertebral artery stenosis are most common. The vertebral artery hypoplasia is a risk factor of patients with posterior circulation cerebral infarction.
