目的分析双下肢动脉狭窄闭塞性疾病诊断中多层螺旋CT血管成像(MSCTA)的临床价值。方法回顾性选取100例疑似双下肢动脉狭窄闭塞性疾病患者,均接受MSCTA及数字减影血管造影(DSA)检查。分析MSCTA检查和DSA检查对双下肢动脉狭窄程度的诊断结果,并以DSA检查结果为金标准,比较MSCTA检查对双下肢动脉中重度狭窄与闭塞的诊断效能。结果100例患者中,DSA检查闭塞14例,重度狭窄18例,中度狭窄20例,轻度狭窄25例,正常23例,占比分别为14.00%、18.00%、20.00%、25.00%、23.00%;MSCTA检查闭塞14例,重度狭窄19例,中度狭窄21例,轻度狭窄24例,正常22例,占比分别为14.00%、19.00%、21.00%、24.00%、22.00%。以DSA检查结果为金标准,MSCTA检查双下肢动脉中重度狭窄的灵敏性为89.47%(34/38),特异性为90.32%(56/62),准确性为90.00%(90/100),阳性预测值为85.00%(34/40),阴性预测值为93.33%(56/60)。MSCTA检查双下肢动脉闭塞的灵敏性为92.86%(13/14),特异性为98.84%(85/86),准确性为98.00%(98/100),阳性预测值为92.86%(13/14),阴性预测值为98.84%(85/86)。MSCTA检查双下肢动脉闭塞的特异性、准确性均高于中重度狭窄,差异具有统计学意义(P<0.05);MSCTA检查双下肢动脉闭塞与中重度狭窄的灵敏性、阴性预测值、阳性预测值比较,差异无统计学意义(P>0.05)。结论双下肢动脉狭窄闭塞性疾病诊断中MSCTA的临床价值高。
Objective To analyze the clinical value of multi-slice spiral CT angiography(MSCTA) in bilateral lower extremity arterial steno-occlusive disease.Methods A total of 100 patients with suspected bilateral lower extremity arterial steno-occlusive disease were retrospectively selected and underwent MSCTA and digital subtraction angiography(DSA).The diagnostic results of MSCTA and DSA on the degree of arterial stenosis in both lower extremities were analyzed,and the diagnostic efficacy of MSCTA on moderate to severe arterial stenosis and occlusion in both lower extremities was compared using DSA examination results as the gold standard.Results Among the 100 patients,DSA examined 14 cases of occlusion,18 cases of severe stenosis,20 cases of moderate stenosis,25 cases of mild stenosis and 23 cases of normal,accounting for 14.00%,18.00%,20.00%,25.00%and 23.00%,respectively;MSCTA examined 14 cases of occlusion,19 cases of severe stenosis,21 cases of moderate stenosis,24 cases of mild stenosis,and 22 cases of normal,accounting for 14.00%,19.00%,21.00%,24.00%,and 22.00%,respectively.Taking DSA as the gold standard,the sensitivity of MSCTA in detecting moderate to severe arterial stenosis in both lower extremities was 89.47%(34/38),the specificity was 90.32%(56/62),the accuracy was 90.00%(90/100),the positive predictive value was 85.00%(34/40),and the negative predictive value was 93.33%(56/60).The sensitivity of MSCTA in detecting bilateral lower-extremity arterial occlusion was 92.86%(13/14),the specificity was 98.84%(85/86),the accuracy was 98.00%(98/100),and the positive predictive value was 92.86%(13/14),and the negative predictive value was 98.84%(85/86).The specificity and accuracy of MSCTA examination for bilateral lower extremity arterial occlusion were higher than those of moderate to severe stenosis,and the difference was statistically significant(P<0.05).The sensitivity,negative predictive value and positive predictive value of MSCTA examination for bilateral lower extremity arterial occlusion and moderate to severe stenosis were compared,and the difference was not statistically significant(P>0.05).Conclusion MSCTA has high clinical value in the diagnosis of bilateral lower extremity arterial stenoocclusive disease.
