彩色多普勒超声诊断2型糖尿病患者下肢动脉病变

目的分析彩色多普勒超声用于诊断2型糖尿病患者下肢动脉病变的价值。方法对800例2型糖尿病患者的3组下肢动脉：胫前动脉（ATA）、胫后动脉（PTA）和足背动脉（DPA）行彩色多普勒超声检查,从管径、斑块及血流动力学方面进行比较。结果糖尿病患者下肢动脉出现斑块最多、狭窄最严重的是ATA远心端和DPA,PTA斑块相对较少,狭窄较轻。糖尿病包括糖尿病足双侧下肢动脉在管径、管腔最大狭窄率及血流动力学方面差异无统计学意义,病变程度相当。结论彩色多普勒超声在诊断糖尿病下肢动脉病变中具有重要价值,有助于了解血管狭窄程度及血流动力学方面的信息,指导临床治疗。

Color Doppler ultrasound in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus

Objective To analyze the value of color Doppler ultrasound in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus. Methods A total of 800 patients with type 2 diabetes mellitus underwent color Doppler ultrasonography to examine anterior tibial artery (ATA), dorsalis pedis artery (DPA) and posterior tibial artery (PTA).Ultrasonic findings including vascular diameter, stenosis ratio and hemodynamics of lower extremity arterial disease were analyzed retrospectively. Results ATA and DPA had more plaques and stenosis than PTA. There was no statistical difference of vascular diameter, stenosis ratio and hemodynamics between left and right lower extremity artery in patients with type 2 diabetes mellitus including diabetic foot. Conclusion Color Doppler ultrasound is a useful method in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus, providing information of stenosis ratio and hemodynamics of lower extremity artery, so as contributing to the clinical therapy of this disease.
