目的探讨彩色多普勒超声对糖尿病下肢动脉病变的临床诊断价值及意义。方法应用彩色多普勒超声仪分别对65例糖尿病患者(观察组)和65例非糖尿病患者(对照组)进行超声检查,观察其声像图特点及血管病变情况。结果观察组下肢动脉管腔斑块,狭窄、闭塞的发生率均明显低于对照组,组间比较均有显著差异(P均<0.05);观察组下肢动脉血流内径较对照组明显变细,下肢动脉IMT值、血流量、阻力指数(RI)较对照组明显增加,各参数比较均有显著差异(P均<0.05)。结论彩色多普勒超声检查能客观评价糖尿病下肢血管病变程度,准确判断出患者下肢动脉的内膜、IMT、斑块及血流改变情况,具有无创、简便、重复性好等优点,是目前糖尿病下肢血管病变检查的一种较佳方法。
Objective To investigate the value and significance of color Doppler ultrasonography in the diagnosis of diabetic lower extremity arterial disease. Methods Totally 65 patients with diabetes mellitus (observation group) and 65 non-diabetic patients (control group) were examined by color Doppler sonography. The sonographic features and vascular lesions were observed. Results The incidence of plaque, stenosis and occlusion of lower extremity arteries in the observation group were significantly lower than those in the control group (all P <0.05). The arterial blood flow diameter of lower extremity in the observation group was significantly thinner than that in the control group , Lower limb artery IMT value, blood flow, resistance index (RI) than the control group increased significantly, the parameters were significantly different (P all <0.05). Conclusion Color Doppler ultrasonography can objectively evaluate the degree of vascular lesion in lower extremities of diabetic patients, accurately determine the changes of the intima, IMT, plaque and blood flow of lower extremity arteries. It has the advantages of noninvasive, simple and good repeatability, Lower extremity vascular lesions check a better way.
