The Most Severe Stage of Chronic Venous Disease: An Update on the Management of Patients with Venous Leg Ulcers.

Venous leg ulcers (VLUs) are the most severe manifestation of chronic venous disease (CVD). Due to their chronic nature, high recurrence rate and slow healing time, VLUs account for 80% of all leg ulcers seen in patients with CVD. VLUs impose a heavy burden on patients that reduces their quality of life; VLUs also represent a major socioeconomic impact due to the cost and duration of care. The primary medical approach to treating VLUs is local compression therapy in combination with venoactive drug (VAD) pharmacotherapy to promote the reduction of the inflammatory reaction initiated by venous hypertension. Micronized purified flavonoid fraction (MPFF; Daflon®) is the most widely prescribed VAD. MPFF counteracts the pathophysiologic mechanisms of CVD and ulceration and has proven to be an effective adjunct to compression therapy in patients with large and chronic VLUs. Two other non-VAD drugs, pentoxifylline and sulodexide, have also been shown to improve VLU healing and are also recommended in addition to compression therapy. However, MPFF is the only VAD with the highest strength of recommendations in the 2018 guidelines for the healing of VLUs.
