糖尿病下肢动脉病变的彩色多普勒超声诊断

Diagnosis of Arterial Pathological Changes of the Lower Limb in Diabetes by Color Doppler Ultrasound

报告了应用彩色多普勒超声对50例糖尿病患者的下肢动脉病变的研究。结果显示糖尿病组下肢动脉内径、血流量低于正常组（P＜0．01），加速度／减速度比值及血流峰值速度高于正常组（P＜0．001）。彩色多普勒超声可定量估价糖尿病下肢动脉功能、病变部位和程度。

The paper reports the application of color Doppler ultrasound for investigation of the arterial pathological changes of the lower limbs of 50 diabetes mellitus patients. The result showed that the interior diameter and volume flow of the arteries were all significantly lower than tha of the control (P < 0.01), whil the peck forward velocity were significantly higher (P < 0.001).It is concluded that color Doppler ultrasound can quantitatively evaluate the arterial function and the location of the pathologic changes of the lower limbs of the diabetes mellitus patients.
