摘　　要：目的探讨多层螺旋CT血管成像（MSCTA）在评价后循环缺血患者椎基底动脉粥样硬化病变中的价值。方法对150例后循环缺血患者在7d内行头颈部MScTA检查，观察各支椎基底动脉斑块的发生率，评价不同性质斑块与脑梗死发生的相关性分析。结果150例患蕾中共检出斑块108处，梗死组易损斑块（83．3％）高于短暂性脑缺血发作（TIA）组（51．2％），差别有显著性意义（P〈0．01）。比较易损斑块组、稳定斑块组和无斑块组3组间后循环梗死发生率总体差别有显著性意义（P=0．007），易损斑块组后循环梗死发乍率（52．2％）显著高于稳定斑块组（28．2％）（P=0．016）和无斑块组（23．3％）（P=0．008），而稳定斑块组和无斑块组之间差别无堀著性意义（P=0．648）。结论MSCTA能准确检测出椎基底动脉粥样硬化斑块及性质，评价不同斑块与脑梗死发生的相关性，是确诊后循环缺血患者病因检查的首选方法。Objective To investigate the value of multi slice spiral CT artery angiography（ MSCTA） in evaluation of patients with isehemia of the posterior circulation and vertebral artery atherosclerosis. Methods MSCTA for head and neck were performed in 150 patients witb ischemia of the posterior circulation within 7 days after the onset of ischemia. The incidence of the atherosclerotic plaque for each branch of the vertebrobasilar was evaluated and calculated. The correlation between various types of atherosclerotic plaque and the occurrence of cerebral infarction were also calculated. Results A total of 108 plaques were found in 150 patients. In all the cases, the number of vulnerable plaque in infarction group （83.3%） were significantly more than that in TIA group （51.2%） （P〈0.01）. The incidences of the infarction of post circulation among vulnerable plaque group , stable plaque group and no plaque group were significantly different . The incidence of post circulation infarction in vulnerable plaque group（52.2%） was significantly（P〈0. 01 ） higher than those in stable plaque group（ 28.2% ）and no plaque group. There were no difference between stable plaque group and no plaque group（P= 0. 648）. Conclusion MSCTCA can accurately detect vertebrobasilar atherosclerosis plaque, and evaluate the relevance of the occurrence of different plaque and the cerebral infarction. It is the preferred method for the diagnosis of the cause of posterior cir- culation ischemia.
