Study on the relationship between severe peripheral arterial occlusive disease and diabetic foot

Abstract

Objective To investigate the prevalence of peripheral arterial occlusive disease(PAD)and diabetic foot among in-patients with diabetes,and to analyze the relation between these two complications.Methods Five-hundred and twenty-three patients with type 2 diabetes were enrolled.Fasting and postprandial plasma glucose,HbA_(1C),serum lipid profile and urinary albumin were determined.Femoral artery,profunda femoraJ artery.popliteal anory,anterior tibial artery,posterior tibial artery,and peroneal artery were checked by Doppler ultrasonographv.The patients were then subdivided into groups with non-PAD,mild PAD(artery stenesis<50%)and severe PAD(anery stenosis≥50%).Diabetic foot was diagnosed using Wagner criterion.Results Among the 523 palients.95 patients were afflicted with diabetic foot,311 patients with PAD in which 131 with severe PAD.As many as 55 severe PAD cases were found in diabetic foot patients.Multivariate logistic regression analysis revealed that severe PAD was significantly associated with diabetic foot(OR=5.00),other risk factors included smoking habit, hypertension and neuropathy. Conclusion Severe PAD seems to be the most important risk factor related to diabetic foot. Key words: Diabetic foot; Peripheral arterial diseases; Ultrasonography; Doppler; color
