上肢无脉症的MSCTA诊断（附44例分析）

目的：探讨多层螺旋CT血管成像（MSCTA）在上肢无脉症的应用价值。方法：对44例临床疑患无脉症的患者行MSCTA检查,所获数据传输至AW4.2工作站,进行最大强度投影（MIP）、曲面重建（CPR）、容积显示（VR）及高级血管分析（AVA）等多种后处理并结合原始图像进行分析。结果：44例的血管重建图像对无脉症均有特征显示,动脉硬化闭塞症34例,多发性大动脉炎5例,外伤后动脉栓塞2例,动脉内癌栓2例,锁骨下动脉瘤人工血管置换术后1例。结论：MSCTA可以清楚而准确的显示上肢无脉症的病变情况,是上肢无脉症理想的影像学检查方法。

Diagnosis of multi-slice computed tomography angiography on the pulseless disease in upper limbs

Objective：To discuss the application value of multi-slice spiral computed tomography angiography （MSCTA） in the pulse-less disease in upper limbs. Methods：44 cases of patients, suspected having pulseless disease, successively were undergone MSCrA, then the results were put into AW 4.2 workstation, carried through tile pest-process, comparison and analysis according to the original images after using the maximum intensity pmjecting（MIP）, curved planar reconstruction（CPR）, volume rendefing（VR）, advanced vessel analysis（AVA） and other methods. Results： Of all the 44 cases of patients, their vessels reconstruction images all show sills of pulseless disease. Among them, arteriosclerotic occlusive disease appeared in 34 eases, multiple aorto-arteritis, in 5 eases, post-traumatic artery emlbolization 2 cases, arterial thrombosis 2 eases, subclavian aneurysm graft replacement 1 ease. Conclusion： MSCTA can clearly and veraciously show the changing situation of upper limb pulseless disease, and it is a perfect examining method in the study of imaging.
