摘　　要：目的:探讨多排螺旋CT血管造影在下肢动脉支架置入术后疗效评价的价值。方法:收集我院2010年7月至2016年12月共23例因下肢动脉硬化闭塞症行支架置入术,术后先行CTA检查、后行DSA检查的的影像资料,对置入支架的评价进行回顾性对比分析。结果:以DSA为标准,CTA评价置入支架通畅诊断符合率100%、狭窄诊断符合率100%、狭窄程度分级符合率75%、闭塞诊断符合率100%。结论:下肢动脉CTA检查简单易行,可比较准确评估支架的情况,在下肢动脉病变支架植入术后复查有很好的应用价值,可作为首选检查方法。Objective： To discuss the application of 16 spiral CT angiography in postoperative re - examination of low- er limb artery stent implantation. Methods： During the period from July 2010 to February 2016 at the Hospital, CT angiogra- phy （CTA） was carried out in 23 patients who had received stent implantation for arteriosclerotic occlusion of low limb, and the CTA imaging manifestations were compared with their DSA findings within two weeks . Results： Taking DSA findings as standard. Of the 23 patients , no stenosis was seen in CTA in 8 patients ; II - IV grade stenosis in 8 , the number was the same compare to DSA, but the degrees of 2 stents judged by CTA were not aonsistent with DSA ; complete occlusion in 11, they are the same. Conclusion： Lower limb arterial CTA examination is a safe and no - invasive technique , it can display the stent inner canal and it is of great value in postoperative re - examination of lower limb artery stent implantation.
