Value of color Doppler imaging in diagnosis diabetic vascular lesion of lower limbs

Objective To study the value of diabetic vascular lesion of lower limbs with color Doppler imaging.Methods We observed the lower extremity arterials vascular intima,plaque,narrow and occlusion in 36 patients with diabetic foot with color Doppler imaging.Digital subtraction angiography(DSA) with 9 of diabetic foot gangrene was observed.Results Vascular lesions was mainly below popliteal arteries and lesions was multi-segmental.The patients with diabetic foot gangrene was more serious than the patients with diabetic foot non-gangrene.Compared with DSA,color Doppler imaging in diagnosis of diabetes vascular lesions in the lower extremities were much accurate.Conclusion Compared with DSA,color Doppler can replace DSA in the diagnosis of diabetic lower extremity vascular disease.
