Background: Diabetes mellitus has increased the risk of peripheral vascular diseases by causing endothelial and smooth muscle cell dysfunction in peripheral arteries. The ankle-brachial index (ABI) is a simple, noninvasive and widely used test that detects peripheral arterial disease (PAD).Aim: the study aims to assess peripheral vascular disease degree for diabetic patients. Design: Descriptive research design. Sample: Purposeful samples with number of 50 diabetic patients were selected. Setting: the present study was conducted at the diabetic out-patient clinic at Minia university hospital. Tools: Data were collected using two tools; the first tool included questions related to demographic characteristics, medical and life style data. The second tool is ankle brachial index. Results: The main finding of the study were two thirds were females with mean average age were 50.9 ± 10.5 years and two thirds of the studied sample have mild obstruction  while the other third were had a moderate obstruction of peripheral vascular disease. There statistical significance relation between the duration of type 2 diabetes and accompanied medical illness among studied sample regarding their ankle brachial index levels (p≤ .03&.02) respectively. Conclusion: Around two thirds of the studied sample had mild level of peripheral arterial obstruction and there was significant difference between the duration of type 2 diabetes and accompanied medical illness regarding their ankle brachial index. Recommendation: Planning a program that helps diabetic patients about of peripheral vascular disease management.
