摘要
目的观察糖尿病足(DF)病人下肢动脉形态学和血流动力学的改变。方法正常受试者(NS)25例,糖尿病(DM)病人26例,非肢端坏疽糖尿病足病人(NGDF)30例和肢端坏疽糖尿病足(GDF)病人26例。应用Acuson128XP/10彩色电脑声像仪,线阵探头,频率7.0 MHz,观察下肢动脉管径和血流的变化。结果DF两组病人下肢动脉血管病变,主要从腘动脉部位开始动脉硬化,尤其以胫后和足背动脉最为显著,动脉狭窄和闭塞是肢端缺血、坏疽的主要病因。观察发现,DM病人已有下肢腘动脉血流速度增高的血流动力学改变,GDF组病人胫后和足背动脉血流速度明显低于其他各组。结论彩色多普勒超声检测能帮助临床对糖尿病足下肢血管病变严重程度的判断、糖尿病足的诊断和治疗方案的制定有实用价值。
Objective To observe the changes of hemodynamics and morphology of lower limbs artery in diabetic foot patients. Methods 26 patients with diabetes mellitus （DM）, 30 patients with non-gangrenous diabetic foot （NGDF）,26 patients with gangrenous diabetic foot（GDF）and 25 normal subject （NS） were studied. The changes of intraluminal diameter and hemodynamies in lower limbs arteries were observed by color Doppler ultrasonography. Results Atheroselerosis was mainly in arteries below knee, including popliteal, tibial and dorsal arteries. Arterial stenosis and occlusion were the cause of gangrene. In diabetic patients, Vmax of popliteal artery was increased. The Vmax of pos terior tibial artery and dorsal artery in GDF was lower than that of other groups. Conclusions The color Doppler ultrasonography should be useful for deciding the degree of stenosis and the diagnosis of DF.
