Graduated Compression Elastic Stockings Reduce Lipodermatosclerosis and Ulcer Recurrence

Objective: To assess the effect of elastic stockings on reducing the area of lipodermatosclerosis in patients with healed venous ulceration. Design: Patients in this study were part of a randomised controlled trial to assess elastic stockings in preventing venous ulcer recurrence. Setting: Leg ulcer clinic at a tertiary teaching hospital. Patients: Consecutive consenting patients with leg ulcers due to venous disease alone, that had healed 2 weeks previously. Interventions: Patients were randomised to below-knee graduated compression stockings (Venosan 2003) or no stockings. Main outcome measures: Patients had the area of lipodermatosclerosis measured on admission to the study and at 6-monthly intervals. Time to ulcer recurrence was also recorded for a 2-year follow-up period. Results: One hundred and fifty-three patients were randomised to the main study (stockings 72, no stockings 81); 52 had re-ulcerated by 6 months (15 stockings, 37 no stockings). Lipodermatosclerosis was significantly reduced after 6 and 12 months in those patients wearing stockings but not in the control group (repeat measures ANOVA p = 0.01, p = 0.04). The initial area of lipodermatosclerosis was significantly larger in those patients who re-ulcerated within 2 years of entering the study compared with those who did not re-ulcerate (re-ulceration, 293 cm2; no re-ulceration, 50 cm2). Conclusions: Elastic stockings alone can improve the skin changes of lipodermatosclerosis and lower the rate of ulcer recurrence.

Changes in calf muscle function in chronic venous disease.

The aim of this study was to assess calf muscle function in patients with chronic venous disease and recently healed venous ulcers. Forty-nine consecutive patients with recently healed proven venous leg ulcers and 20 age- and sex-matched control subjects were entered into this study. Both patients and control subjects underwent duplex scan evaluation of their leg veins and isokinetic measurement for calf muscle strength and endurance. Calf muscle function was significantly impaired in patients with chronic venous disease compared with control subjects. Both peak torque/body weight (strength), P = 0.049 (CI 0.3-18.4%) and total work (endurance), P = 0.05 (Cl 6.01-97.6 Nm) were reduced. This study has shown that patients with chronic venous disease have a significant impairment of calf muscle function compared with healthy control subjects. This study suggests that there is a need to evaluate whether a programme to improve muscle strength may be of benefit in both healing and preventing the recurrence of chronic venous ulcers.
