摘　　要：目的探讨在临床中诊断糖尿病下肢动脉病变时使用多层螺旋CT的应用价值。方法选取2019年1月—2023年1月福建省建瓯市立医院检查的70例疑似糖尿病下肢动脉病变患者,所有患者都进行多层螺旋CT检查,以数字减影血管造影诊断的结果为金标准,分析多层螺旋CT诊断糖尿病下肢动脉病的准确度、灵敏度、特异度、漏诊率及误诊率,并比较糖尿病下肢动脉病变患者和非糖尿病下肢动脉病变患者股动脉、腘动脉和胫前动脉的管腔内径。结果数字减影血管造影诊断结果显示,70例疑似糖尿病下肢动脉病变患者中阳性64例,阴性6例,多层螺旋CT诊断阳性63例,阴性7例,其准确度、灵敏度及特异度分别为95.71%、96.88%、83.33%,漏诊率为3.13%(2/64),误诊率为16.67%(1/6)。多层螺旋CT与数字减影血管造影比较,一致性较好(Kappa=0.75);糖尿病下肢动脉病变患者股动脉、腘动脉和胫前动脉的管腔内径小于非糖尿病下肢动脉病变患者的股动脉、腘动脉和胫前动脉的管腔内径,差异有统计学意义(P<0.05)。结论多层螺旋CT诊断糖尿病下肢动脉病变在临床中具有一定的应用价值,其诊断效能较高,且发现糖尿病下肢动脉病变患者的股动脉、腘动脉和胫前动脉的管腔内径较小。Objective To investigate the application value of multi-slice spiral CT in the diagnosis of diabetic lower extremity arterial disease.Methods From January 2019 to January 2023,70 patients with suspected diabetic lower ex-tremity arterial disease were selected for examination in Jian'ou Municipal Hospital.All patients underwent multi-slice spiral CT examination.With the results of digital subtractive angiography as the gold standard,the accuracy,sen-sitivity,specificity,missed diagnosis rate and misdiagnosis rate of multi-slice spiral CT in the diagnosis of diabetic lower extremity arterial disease were analyzed.The lumen diameters of femoral artery,popliteal artery and anterior tibial artery were compared between diabetic and non-diabetic patients with lower extremity arterial disease.Results Digital subtractive angiography diagnosis results showed that 64 cases were positive,6 cases were negative,63 cases were positive and 7 cases were negative.The accuracy,sensitivity and specificity were 95.71%,96.88%and 83.33%,respectively.The missed diagnosis rate was 3.13%(2/64)and the misdiagnosis rate was 16.67%(1/6).The consistency of multi-slice spiral CT was better than that of digital subtractive angiography(Kappa=0.75).The lumen diameter of femoral artery,popliteal artery and anterior tibial artery in diabetic lower limb artery disease patients was smaller than that of femoral artery,popliteal artery and anterior tibial artery in non-diabetic lower limb artery disease patients,and the differences were statistically significant(P<0.05).Conclusion Multi-slice spiral CT has a certain clinical applica-tion value in the diagnosis of diabetic lower extremity arterial disease,and its diagnostic efficiency is high,and it is found that the femoral artery,popliteal artery and anterior tibial artery in diabetic lower extremity arterial disease pa-tients have smaller lumen diameter.
