彩色多普勒检测糖尿病足患者下肢动、静脉病变的研究

Detection of lower extremity arterial and vein lesions in Diabetic foot patients by color Doppler imaging

本文报告经临床确诊为糖尿病足病人47例,其中非肢端坏疽组24例,肢端坏疽组23例,以彩色多普勒超声检测下肢动,静脉形态学及血流动力学改变,并与20例对照组进行对比分析,目的探索其发病的血管方面因素,观察结果表明,糖尿病足病人的下肢血管病变,主要为膝关节部位以下动脉(包括胫后及足背动脉等)硬化,动脉狭窄闭塞是导致肢端缺血,坏疽的主要病因,严重者还可出现胫后静脉血流淤滞,阻塞等变化,作者认为这种检查方法,可帮助临床判断糖尿病足下肢血管病变的严重程度,对确定治疗方案和治疗后的随访观察均有实用价值。

This paper reported the lower extremity arterial and vein lesions in 47 patients with Diabetic foot by color doppler flow imaging(CDFI) ,and comparism with 20 normal subjects. The purpose of this study was to expore the morphologic and hemodynamic changes in the lower extremity blood vessels. The results showed that arterial atheriosclerosis mainly were below kenn, including popliteal, tibial and dorsal artery. Arterial stenosis and occlusion is the cause of gangrene. In some serious cases, we found that the vein was sludging of blood and obstruting thrombus. It is conclude that CDFI should be useful for decide the degree of stenosis and also valuable to decide the treating program.
