代谢综合征患者下肢动脉病变的彩超研究

目的:探讨代谢综合征(metabolic syndrome, MS)患者的下肢动脉病变情况.方法:应用彩色多普勒超声对50例MS患者下肢动脉进行检查,并与30例健康志愿者对照,测量血管内径、收缩期最大流速、内-中膜厚度、斑块大小及数目.结果:50例中,内-中膜增厚大于1.1 mm者41例,有粥样斑块并引起不同程度狭窄者33例.股总动脉、腘动脉、足背动脉的内膜明显厚于对照组(P＜0.01或P＜0.05),斑块数明显多于对照组(P＜0.01).结论:MS患者下肢动脉发生了程度不等的病变,用彩色多普勒超声检测能明确MS患者下肢动脉病变的部位和程度,具有重要的临床意义.

Color Doppler ultrasound study on pathological changes of lower extremity arteries in patients with metabolic syndrome

Objective: To explore the pathological changes of lower extremity arteries of patients with metabolic syndrome. Methods: Fifty patients with metabolic syndrome (MS) and 30 normal volunteers were included in this study. The inner diameters, peak systolic velocities and intima-media thicknesses of the lower extremity arteries, and the sizes and numbers of the plaques in the lower extremity arteries were obtained with color Doppler ultrasound (CDU). Results: In the fifty MS patients, the intima-media thicknesses of forty-one were thicker than 1.1 mm and thirty-three had plaques which had brought stenosis in different degrees. The intima-media thicknesses of the common femoral, popliteal and posterior tibial arteries in the MS patients were significantly thicker than those in the normal volunteers (P<0.01 or P<0.05), and a greater number of plaques in the lower extremity arteries were observed in the patients, as compared with the normal volunteers (P<0.01). Conclusion:Various pathological changes had taken place in the lower extremity arteries of the MS patients. The sites and degrees of the lower extremity arterial diseases in MS patients can be definitely detected with CDU.
