The value of color Doppler ultrasound in the diagnosis of lower extremity vascular disease in type 2 diabetes and an analysis of related factors.

BACKGROUND: The aim of this paper is to explore the application and clinical significance of color Doppler ultrasound (CDU) in diagnosing lower extremity vascular disease in type 2 diabetes mellitus (T2DM) patients.

METHODS: The lower extremity arteries of 81 patients with T2DM and 50 control patients were examined by CDU for blood vessel diameter, intima-media thickness, plaque on the vessel wall, lumen stenosis and filling defect in blood flow. The occurrence of diabetes mellitus was investigated in additional T2DM patients of various ages.

RESULTS: Left popliteal artery, left and right dorsal artery of the foot; the incidence of atherosclerotic plaque, stenosis and occlusion of the lower extremity vascular lumen of T2DM patients was significantly higher than that in the control group. Vascular disease in the lower extremities was mainly small and medium vascular disease (lower than popliteal artery), especially the dorsal artery of the foot, for which the difference was statistically significant (P<0.05). The elder patients had a greater chance of lower extremity arterial disease.

CONCLUSIONS: CDU is the examination method of preference for T2DM patients with lower extremity vascular disease. It has a very important clinical significance for early diagnosis, prevention and treatment.
