摘要/Abstract

摘要： 本研究的目的是探讨2型糖尿病（T2DM）患者糖尿病足中，应用多层螺旋CT（MSCT）的诊断价值。选取T2DM患者130例，其中合并糖尿病足患者35例（Wagner分级0～2级22例，3～4级为13例，无5级），单纯T2DM患者95例，给予MSCT检查。结果发现伴糖尿病足患者胫后动脉、腘动脉和股动脉截面积明显小于单纯T2DM患者（P<0.05）；Wagner级3～4级糖尿病足患者胫后动脉、腘动脉和股动脉截面积明显小于Wagner级0～2级糖尿病足患者（P<0.05）；胫后动脉、腘动脉和股动脉截面积诊断Wagner级3～4级糖尿病足的ROC曲线下面积分别为0.685、0.927和0.822（P<0.05）。研究结果证实在诊断T2DM患者糖尿病足严重程度中，MSCT有一定应用价值，值得临床使用。

Abstract: The purpose of this study was to investigate the diagnostic value of multislice spiral CT (MSCT) in diabetic foot of patients with diabetes mellitus type 2 (T2DM). 130 patients with T2DM were selected, including 35 patients with diabetic foot (22 patients with Wagner grade 0~2, 13 patients with grade 3~4, no grade 5), and 95 patients with simple T2DM, the MSCT was performed. In patients with diabetic foot, the posterior tibial artery, popliteal artery and femoral artery cross-sectional area were significantly smaller than those in patients with T2DM alone (P<0.05). The posterior tibial artery, popliteal artery and femoral artery cross-sectional area of Wagner class 3 to 4 diabetic foot patients were significantly smaller than Wagner class 0 to 2 diabetic foot patients (P<0.05). The area under ROC curve of posterior tibial artery, popliteal artery and femoral artery cross-sectional area in diagnosing Wagner's grade 3 to 4 diabetic feet were 0.685, 0.927 and 0.822, respectively. These results confirm that MSCT has certain application value in the diagnosis of diabetic foot severity in T2DM patients and is worthy of clinical use.
