Edema control in the management of disabling chronic venous insufficiency.

This study was undertaken to assess the biomedical and socioeconomic rationale of edema control in disabling chronic venous insufficiency (CVI). In this 15-year retrospective survey (1974 through 1988) edema control was achieved by use of Unna's boot for leg ulcerations and by compressive hosiery for prevention of ulcerations. The study included 2,317 self- or physician-referred patients with disabling CVI, of whom 998 presented with venous stasis ulcers, many with recurrent ulcerations. Two hundred thirty-six patients were seen and treated only once and never returned. They were listed as not healed. Including patients who never returned after the first visit, the overall healing rate was 60.9%. Excluding the nonreturning patients, the overall rate of verified healing was 73.3%. The healing rate was 91% for first ulcers of complaint patients (patients treated at least 12 times in 32 weeks). The Unna's boot, being a functional substitute for the failing muscle pump in CVI, is a noninvasive and ambulatory method of controlling edema and treating ulcers in CVI. It does not interfere with patients' activities, it is inexpensive, and it is adaptable to middle aged and elderly ambulatory populations.
