目的利用CT主动脉造影,分析、定位脊髓跟大动脉(the artery of Adamkiewicz,AKA).方法对拟诊主动脉疾病的92例患者行螺旋CT主动脉造影,对扫描图片进行横断面、冠状面多维重建,并显示最大强度投影,根据AKA的连续性及“发卡”样特征对其定位分析.结果 51例(55.4％)患者共显影54支AKA(3例显示双支AKA,5.9％),其中87.0％位于T8至T11节段,77.8％发自主动脉左侧.累及胸主动脉的夹层和动脉瘤的AKA检出率分别为44.7％和37.5％,未累及胸主动脉的腹主动脉瘤和主动脉仅呈现粥样斑块者的AKA检出率是67.6％和66.7％,两者差异具有统计学意义(P＜0.05).结论 AKA源自胸腰段的具体位置存在很大变异,螺旋CT主动脉造影为定位AKA提供了可依赖的手段.

Objective To locate and analyze the artery of Adamkiewicz using row CT angiography.Methods 92 patients with snspicion for aortic lesions underwent row CT angiography.Transverse sections,coronal multiplanar reformations (MPR) and maximum intensity projections(MIP) were generated and displayed.AKA was identified according to its continuity of the intercostal or lumbar artery and "hairpin"configuration.Results 54 A K A were detected in 51 of 92 patients(55.4％),3 patients (5.9％) had a second AKA.87.0％ of AKA originated at the T8 through T(1 1) level and 77.8％ occurred on the left side of aorta.The detected ratio of AKA in patients with thoracic aorta lesions (aortic dissection or thoracic aortic aneurysms) were 44.7％,37.5％ respectively.However,the ratio in patients without thoracic aorta lesions (abdominal aortic aneurysm or atherosclerotic plaques) was 67.6％ or 66.7％.There was statistically significant difference hetween the two kinds of lesions(P ＜ 0.05).Conclusions The accurate level of AKA has more variations.CT angiography scan is a reliable non-invasive technique to locate AKA.
