Management of leg ulcers.

Although leg ulcers have many causes, the most common etiology is venous or arterial insufficiency. The prime objective in the evaluation of leg ulcers is to uncover the precipitating pathologic process, and the first goal of therapy is to correct or control this underlying condition. Simple laboratory tests and office procedures are adjuncts in diagnosis. Topical care of leg ulcers includes gentle debridement, use of wet dressings and, in selected cases, skin grafting.
