Venous ulcers are open skin sores that most commonly appear around the ankles. When ulceration begins, there is partial skin loss in an already abnormal area. Venous ulcers are generally superficial, irregular in shape, and have moderate-to-high amounts of drainage.
Women are three times more likely than men to have a venous insufficiency ulcer. The risk of ulceration is 7.5 times greater in individuals over the age of 65. Although ulcers are rarely life-threatening, they cause much morbidity from pain, discomfort, and fluid discharge.
