64排螺旋CT血管成像技术诊断下肢动脉硬化闭塞症临床分析

64 Row Helical CT Vascular Imaging in the Diagnosis of Lower Limb Arteriosclerosis Occlusion Disease Clinical Analysis

目的探究64排螺旋CT（CTA）血管成像技术在临床诊断下肢动脉硬化闭塞症（PDA）中的应用价值。方法方便选取该院2014年6月—2015年12月期间收治的38例疑似PDA的患者,行64排螺旋CT血管成像（CTA）检查,后于1-2周内行DSA（数字血管减影）检查,将两种检查结果进行对比。结果以数字血管减影为金标准,370段血管中CTA检查得出相同结论的有350段血管,其检查准确率为94.6%（350/370）,且诊断下肢静脉狭窄（狭窄程度≥50%）的特异度为98.6%（136/138）,灵敏度为92.2%（214/232）。结论 64排螺旋CT血管成像技术可对下肢动脉及其病变进行清晰的显示,评估结果较为可靠,值得推广应用。

Objective To explore 64 row helical CT（CTA） vascular imaging in clinical diagnosis of lower limb arteriosclerosis occlusion disorder（PDA）, the application of value. Methods Convenient selection in our hospital during June 2014 to December 2015 were 38 cases of patients with suspected PDA 64 row helical CT angiography（CTA）, 1 to 2 weeks after DSA（digital subtraction angiography） check, compare two kinds of test results. Results With digital subtraction angiography as gold standard, 370 CTA examination to the same conclusion in the period of blood vessels, 350 section of blood vessels,check its accuracy was 94.6%（350/370）, and the diagnosis of lower limb vein stenosis（stenosis degree of 50% or higher） of98.6%（136/138）, the sensitivity was 92.2%（214/232）. Conclusion 64 row helical CT angiography imaging technology can be clear in lower limb arteries and its pathological changes, according to the evaluation results are more reliable, is worth popularization and application.
