Venous ulcers are open wounds in the leg caused most commonly by longstanding, untreated varicose veins and venous reflux disease. Patients can frequently complain of pain and recurrent cellulitis (infection). Traditionally these ulcers are treated with long-term compression bandages. More recently there is emerging evidence that offering patients keyhole surgery to treat their underlying vein disease may assist wound healing and decrease the risk of ulcer recurrence.
