title: [Update on current care guidelines: chronic leg ulcers].
abstract: Chronic leg ulcer is a common disorder affecting 1.3-3.6 % of people at some time of their life. The etiology of the ulcer can often be identified through careful clinical examination. The majority of leg ulcers are caused by venous or arterial insufficiency. The target of ulcer treatment should always be directed to the cause of the ulcer. Correction of the circulatory disorder is essential for ulcer healing. Since the probability of ulcer healing reduces as the ulcer becomes chronic, effective treatment should be initiated immediately. Skin grafting should be considered for ulcers > 20 cm2 and > 6 months duration.
