64排螺旋CT血管造影在下肢动脉硬化闭塞症患者介入治疗中的应用研究
Study on the application of 64-row spiral CTA in interventional therapy of patients with arteriosclerotic obliterans of lower extremity
摘要
Abstract
Objective:To analyze diagnostic efficacy of 64-row spiral computed tomography angiography(CTA)in patients with arteriosclerotic obliterans of lower extremity,and the application value of that in screen after interventional therapy.Methods:A retrospective analysis was conducted on 76 patients with arteriosclerotic obliterans of lower extremity who admitted to Beijing Huairou Hospital from July 2020 to June 2022,and all patients underwent 64-row spiral CTA.The digital subtraction angiography was used as gold standard.The degree of arterial stenosis,diagnostic efficacy and the situation of the restenosis of artery after interventional therapy of patients with arteriosclerotic obliterans of lower extremity were analyzed.Results:There were 1238 arterial nodules in 76 patients.In the results of 64-row spiral CTA,the results of 1170 arterial nodules were consistent with the results of digital subtraction angiography(94.51%).Among of them,the overestimation rate of 64-row spiral CTA was 4.44%(55/1238)and the underestimation rate of that was 0.57%(7/1238).According to the gold standard of digital subtraction angiography,the accuracy of 64-row spiral CTA was 91.84%in diagnosing the moderate and above moderate arterial stenosis,and the sensitivity,specificity,positively and negatively predictive value of that were respectively 86.91%,93.86%,85.25%and 84.61%.The accuracy,sensitivity,specificity,positively predictive value and negatively predictive value of 64-row spiral CTA were respectively 98.38%,85.71%,99.56%,94.74%and 98.69%in diagnosing arterial occlusion.After 1 year follow-up after interventional therapy,the rate of the restenosis of 76 patients was 13.16%as the examination of 64-row spiral CTA,and there was a total of 168 vascular nodules,and the diagnostic coincidence rate of 64-row spiral CTA was 97.62%(164/168).Conclusion:The 64-row spiral CTA can assess the degree of arterial occlusion of lower extremity in patients with arteriosclerotic obliterans lower extremity,which has favorable diagnostic efficacy and higher consistency with digital subtraction angiography.It is conducive to formulate the treatment plans,which also has favorable application value for the diagnosis of the restenosis after interventional therapy.关键词
