What is an arterial ulcer?

An ulcer is an area of full-thickness skin breakdown. An arterial ulcer is an ulcer due to inadequate blood supply to the affected area (ischaemia). Arterial ulcers tend to occur on the lower legs and feet, and may be acute, recurrent or chronic. Ulcers may have multiple contributing factors; these ‘mixed ulcers’ constitute roughly 15% of all leg ulcers.
