Target vessel revascularization of diabetic foot according to angiosomes

Abstract

Peripheral arterial disease is a major world-wide health problem. It affects about 12% – 14% of the general population. Chronic limb threatening ischemia is defined as patients with ischemic rest pain or with ischemic skin lesions in the form of ulcers or gangrene with proven peripheral arterial disease. Chronic limb threatening ischemia is usually caused by obstructive atherosclerotic disease. There are several risk factors that contribute for the development and progress of peripheral vascular disease including Diabetes Mellitus, hypertension, hyperlipidemia and smoking. The diagnosis of peripheral arterial occlusive disease is usually made clinically by medical history and ankle to brachial index (ABI) measurement. If the blood pressure in the ankle is much different to that in the arm, it means that the arteries of lower limb are affected. CT angiography or arterial duplex can build up a map of the arteries and show sites of narrowing or occlusions.
