Abstract
The postphlebitic syndrome is a significant management problem that af fects a large number of patients. Primary prophylaxis of deep-vein throm bophlebitis would reduce the risk of developing the postphlebitic syndrome and should be considered in high-risk patients. Patients who have had a phlebitis should be monitored with noninvasive tests of the deep venous circulation for the development of venous valve incompetence. Patients with venous hyperten sion should be placed in compression stockings to prevent the postphlebitic syn drome. In patients who progress to venous ulceration, several aggressive measures must be undertaken. Systemic treatment includes management of obesity, edema, immobility, poor nutrition, and comorbid illnesses. Some pa tients may require a short hospitalization of bed rest, lower limb elevation, and daily dressings and wound care. Outpatient therapy requires sustained com pression of 35 to 40 mmHg at the ankle for many months to allow the ulcer to heal. The standard bandage material is Unna's boots, which is applied every one to two weeks by a trained nurse. Cadexomer iodide is an effective local treat ment that helps debride the ulcer and accelerate healing. Finally, pentoxifylline therapy has also been shown to significantly improve the healing of venous ul cers.
