超声联合超声下ABI值检测糖尿病血管病变的临床诊断价值

Clinical diagnostic value of detection of ultrasound combined with ankle brachial indexes by ultrasound in diabetic vascular lesions

目的探讨超声联合超声下踝肱指数（ABI）检测糖尿病血管病变的临床诊断价值。方法选择2014年9月~2015年12月本院收治的100例糖尿病患者作为研究对象,均经动脉造影确诊。将动脉造影检测结果作为对照组,超声多普勒联合超声下ABI检测作为观察组,比较两组的胫后动脉及足背动脉管腔内径,检出动脉斑块形成及出现狭窄、闭塞的比例,同时分析超声联合超声下ABI检测的阳性率。结果观察组的胫后动脉管腔内径、足背动脉管腔内径显著大于对照组,差异有统计学意义（P〈0.05）。两组的动脉斑块形成及出现狭窄、闭塞的比例比较,差异无统计学意义（P〉0.05）。两组的阳性诊断率和阴性诊断率比较,差异无统计学意义（P〉0.05）。结论超声联合ABI能有效测定下肢动脉管径,尤其能诊断动脉管腔的形态变化,其阳性诊断率较高。

Objective To explore the clinical diagnostic value of detection of ultrasound combined with ankle brachial indexes in diabetic vascular lesions.Methods 100 patients with diabetes in our hospital from September 2014 to December 2015 were selected as the research group,all patients were diagnosed by coronary angiography.The detection results of coronary angiography was selected as the control group,the ABI test was used as the observation group.The inner diameter of posterior tibial artery and foot dorsal artery,the formation of atherosclerotic plaques and the proportion of stenosis and occlusion was compared between the two groups.Additionally,the positive diagnosis rate by using ultrasound in combination of ABI values was analyzed.Results The inner diameter of posterior tibial artery and foot dorsal artery in the observation group was larger than that in the control group,with significant difference（P〈0.05）.There was no significant difference in the proportion of formation of artery plaques,stenosis and occlusion between the two groups（P〉0.05）.There was no significant difference in the positive diagnosis rate and negative diagnosis rate between the two groups（P〉0.05）.Conclusion Ultrasound combined with ABI can effectively determine the diameter of the lower limb artery,especially in the diagnosis of the morphological changes of the lumen of the artery,the positive diagnosis rate is higher.
