Management of venous ulcers

Chronic venous insufficiency (CVI) results from venous hypertension secondary to superficial or deep venous valvular reflux, as well as venous obstruction. The most severe clinical manifestation of CVI is venous leg ulceration that can result in significant morbidity, including venous gangrene and amputation, albeit rare. Treatment modalities are aimed at reducing venous hypertension. Diuretic therapy, although widely used, only provides short-term improvement of the edema but provides no long-term benefit. Compression therapy is the cornerstone in the management of CVI. Compression can be achieved using compression bandaging, compression pumps, or graduated compression stockings. Topical steroid creams may reduce inflammation, venous eczema, and pain in the short term, but they can be detrimental in the long run. Apligraf (a living, bilayered, cell-based product) in conjunction with compression therapy was noted to be more effective in healing venous leg ulcerations, when compared with treatment with compression therapy and zinc paste. Endovascular and surgical techniques that minimize valvular reflux and relieve venous obstruction improve venous hemodynamics, promoting wound healing.
