上肢无脉症的MSCTA诊断

VALUE OF MULTI-SLICE COMPUTERIZED TOMOGRAPHY ANGIOGRAPHY IN THE DIAGNOSIS OF PULSELESS DISEASE IN UPPER LIMBS

目的探讨多层螺旋 CT 血管成像(multi-slice computerizde tomography angiography,MSCTA)在上肢无脉症的诊断价值。方法对34例无脉症的患者行 MSCTA 检查,所获数据传输至 AW 1.2 工作站,进行最大强度投影、曲面重建、容积显示及高级血管分析等多种后处理并结合原始图像进行分析.结果 31例血管重建图像对无脉症均有特征显示,动脉硬化闭塞症24例,多发性大动脉炎4例,外伤后动脉栓塞2例,动脉内癌栓2例,锁骨下静脉栓塞不伴动脉疾患2例。结论 MSCTA 方法具安全、方便、准确、无创等特点.是上肢无脉症良好的影像学检查方法。

Objective To explore the value of multi-slice spiral computerized tomography angiography（MSCTA） in the diagnosis of pulseless disease in upper limbs. Methods MSCTA technology was used to check 34 patients with the pulseless disease in upper limbs. The obtained data were transmitted to AW 4.2 workstation and carried on multiple post-processing, for example： maximum intensity projecting （ MIP）, curved plane reconstruction （ CPR ）, volume rederening（VR） and advanced vessel analysis（AVA） etc. the multiple post-processing and the primitive image was used to carry on the general analysis. Results The rebuilt blood vessel image had characteristic demonstration to the pulseless disease in upper limbs in all the 34 cases. Twenty-four cases with arteriosclerotic occlusive disease, 4 cases with multiple aorto-arteritis, 2 cases with cancer embolus in artery, 2 cases with artery embolism after trauma, 2 cases with subclavian vein embolism without arterial disease. Conclusion The method of MSCTA has many features such as security, facility, nicety and woundless, it is an ideal imaging methods for diagnosing pulseless disease in upper limbs.
