目的：探讨64排CTA在下肢闭合性血管损伤中的应用价值。方法：回顾性分析8例下肢闭合性血管损伤患者的急诊CTA资料，经二维及三维后处理总结血管损伤的影像学表现。结果：3例动脉断裂，断端血栓形成；3例血栓形成致动脉闭塞，其中1例出现动静脉瘘；动脉狭窄2例，均为软组织肿胀压迫，其中1例合并假性动脉瘤。CTA表现与术中一致。结论：64排CTA能及时有效地显示下肢血管损伤的程度，为临床制定手术方案提供准确的影像学依据。

Objective:To study application of 64-detector CTA in closed vascular injury of low extremity. Methods:Emer-gency CTA materials of 8 patients with closed vascular injury of low extremity were analyzed retrospectively. The radiologic appearances of vascular injury through 2D and 3D reformatted were summarized. Result:3 cases of arterial dissection with end thrombus;3 cases of arterial occlusion with thrombus,one of them accompanied with artery-vein fissure;2 cases of ar-terial stricture because of compression by soft tissue swelling,one of them accompany with pseudo-aneurysm. CTA appear-ances showed coincidence with operation. Conclusion:64-detector CTA can demonstrate injury degree of low extremity vascular and can provide accurate radiologic basis of making operation plan.
