Diabetes is no longer a disease of the affluent west. Global prevalence of diabetes in 2003 was estimated to be 194 million. By 2030, this figure is predicted to rise to 366 million due to longer life expectancy and changing dietary habits. In fact the prevalence is soaring in southern India it may reach an astronomical figure 13% to 18%. In such a scenario knowing about the disease is important [1]. The purpose of the study is to access the percentage of lower limb ischemia in patients with diabetic foot, to study the Efficacy of the lower limb revascularization procedures (open and endovascular) and conventional medical management in ischemic diabetic foot. We also study the role of antiplatelet and anticoagulant agents in ischemic diabetic foot and to study the percentage of patients with diabetic foot prevented from Amputations. The main reasons to diagnose Peripheral artery disease in diabetic individuals are to initiate therapies that decrease the risk of atherothrombotic events, improve quality of life, and decrease disability. A diagnosis of Peripheral artery disease indicates the presence of systemic atherosclerosis that confers additional cardiovascular risk to the patient with diabetes, and gives further impetus to aggressively manage vascular risk factors in this high-risk group. The clinical material for this study consisted of 150 cases of Diabetic foot patients admitted in the surgical wards of Thanjavur Medical College Hospital, Thanjavur during the period September 2016 to September 2017. Various diagnostic and therapeutic criteria were followed, protocols was framed and progress recorded.
