C. Development of stasis ulcer.

DISCUSSION: The increased hydrostatic pressure from incompetent venous valves following DVT predisposes to erythrocyte extravasation, hemosiderin deposition, and brown pigmentation around the ankle. Although the edema that occurs with deep venous insufficiency can predispose to skin infections, these usually are located about the ankle and resolve with adequate short-term care. When patients with a history of DVT are followed beyond 10 years, as many as 80% ultimately develop venous stasis ulcers. While there may be recurrence of DVT in a minority of patients, the incidence of pulmonary embolization is no greater than with the initial episode. Even in a leg severely affected by venous stasis changes, the arterial circulation is unimpaired unless there is concomitant arterial obstructive disease.
