Etiology and Anatomic Distribution of Venous Disease in Patients with Venous Ulcers

ABSTRACT

-Leg ulcers due to chronic venous disease affect 0.5 to 1% of Western populations. Reflux and/or obstruction of the lower extremity veins are the underlying pathophysiological mechanisms. The superficial venous system is the most common site of venous insufficiency in patients with chronic venous disease; however, the incidence of deep venous insufficiency is increased in patients with venous ulcers. Skin damage is most often associated with multisystem incompetence, and it is rare with deep venous reflux alone. Only 30 to 50% of limbs with ulceration have a documented episode of deep vein thrombosis. Recent developments in the diagnosis of venous disease have allowed more accurate identification of the malfunctioning venous segments and a more rational application of surgical treatment.
