目的:分析糖尿病足(DF)患者踝臂指数(ABI)与彩色多普勒超声(CDFI)检查对下肢动脉病变的诊断价值。方法:对佛山市高明区慢性病防治站2012年1月至2015年2月收治的62例DF患者以及60例同期住院的非糖尿病患者进行临床对比分析,对比DF患者与非DF患者在下肢血管彩超以及踝臂指数等方面的差异。结果:两组患者ABI相比较,DF组ABI小于0.9的患者所占比例明显高于非DF组,差异具有统计学意义(P<0.05)。两组彩色多普勒超声检查结果相比,DF组患者内膜增厚比率、斑块发生率、狭窄发生率、闭塞发生情况均较非DF组高,差异具有统计学意义(P<0.05)。与非DF组相比,DF组患者在股浅动脉、股深动脉、腘动脉、胫前动脉、胫后动脉、足背动脉处RI值相对较高,差异具有统计学意义(P<0.05)。结论:DF患者与非DF患者在踝臂指数以及下肢彩色多普勒超声检查之间存在明显差异,通过两项检查可以评估DF患者下肢动脉病变情况。
Objective: To analyze the diagnostic value of ankle brachial index (ABI) and color Doppler ultrasonography (CDFI) in the diagnosis of lower extremity arterial disease in diabetic foot (DF). Methods: A total of 62 DF patients admitted from January 2012 to February 2015 in Gaoming District of Foshan City from January 2012 to February 2015 were enrolled in this study. Sixty non-diabetic patients were enrolled in this study. The clinical data of DF patients and non-DF patients were compared. And ankle-brachial index differences. Results: Compared with ABI in two groups, the proportion of patients with ABI less than 0.9 in DF group was significantly higher than that in non-DF group (P <0.05). Compared with the results of color Doppler echocardiography, the intima thickening rate, plaque incidence, stenosis incidence and occlusion in DF group were significantly higher than those in non-DF group (P <0.05) . Compared with non-DF group, the RI of DF group was relatively higher in superficial femoral artery, femoral artery, popliteal artery, anterior tibial artery, posterior tibial artery and dorsalis pedis artery, the difference was statistically significant (P <0.05) . Conclusion: There is a significant difference between ankle brachial index and color Doppler ultrasonography in DF patients and non-DF patients. Two tests can be used to assess the arterial disease in DF patients.
