目的探讨彩色多普勒超声检查糖尿病患者下肢血管病变的临床诊断价值。方法选择糖尿病患者441例为观察组,健康体检者441例为对照组,采用彩色多普勒超声检查单侧下肢动脉血管形态,血管内径,血管内中膜厚度,血管内斑块、血管狭窄、闭塞情况。结果观察组中239例患者检出存在下肢血管病变,包括内中膜增厚、血管内斑块形成、血管狭窄、闭塞情况,检出率为54.2%,而对照组下肢血管发生病变比例均<5%,并且随病程延长其下肢血管发生病变率增高。结论彩色多普勒超声能及早、准确诊断出糖尿病患者下肢动脉血管病变,糖尿病病程时间与其下肢动脉病变发生率呈正相关,彩超在糖尿病患者早期检查中具有重要意义。
Objective To investigate the clinical value of color Doppler ultrasonography in the diagnosis of lower extremity vascular lesions in diabetic patients. Methods 441 diabetic patients were selected as observation group and 441 healthy subjects as control group. Color Doppler ultrasonography was used to examine the morphology of unilateral lower extremity arterial blood vessels, vessel diameter, intima-media thickness, intravascular plaque, vascular stenosis, Occlusion situation. Results In the observation group, 239 patients had lower extremity vascular lesions, including intima-media thickening, intravascular plaque formation, stenosis and occlusion. The detection rate was 54.2% in the control group, while the incidence of vascular lesion in the control group was < 5%, and with the duration of its lower extremity vascular lesions increased. Conclusions Color Doppler ultrasound can diagnose the arterial disease of lower extremities in diabetic patients earlier and more accurately. The duration of diabetes mellitus is positively correlated with the incidence of lower extremity arterial disease. Color Doppler ultrasound is of great significance in early detection of diabetic patients.
