Arterial ulcers, commonly referred to as ischemic ulcers, are wounds that won’t heal due to inadequate arterial blood flow or low perfusion pressure to the tissues of lower extremities. Precipitating events to the arterial ulcers vary. Such impairment can occur acutely (e.g., trauma, thrombosis) or chronically (e.g., atherosclerosis). Both acute and chronic arterial insufficiency can lead to the formation of lower extremity ulcers. Arterial insufficiency can occur at any level, from large arteries to arterioles and capillaries. Tissue ischemia that leads to leg ulcers tends to occur more in the setting of large vessel or mixed disease [1, 2]. For proper treatment of leg ulcers, it is important to be aware of the different types of leg ulceration, their clinical features, and the various diagnostic and treatment modalities.
