Summary

This multicenter randomized controlled trial evaluates the effect of first-visit foam sclerotherapy (including sub-ulcer foam sclerotherapy) in patients with venous leg ulcer.

Detailed description

To evaluate the effect of first-visit foam sclerotherapy, patients with venous leg ulcers are randomly assigned to either the first-visit foam sclerotherapy group or the scheduled treatment group. The scheduled treatment group represents the current standard of care. The primary outcome of this study is the time to ulcer healing. In addition to the first-visit treatment in the study group, both groups receive endothermal ablation and/or foam sclerotherapy to (further) treat ulcer-related insufficient veins and truncal insufficiency in scheduled treatment visit(s). Class 2 thigh-high compression or the best possible compression therapy tolerated by the patient is provided in both groups. The follow-up period for the primary outcome is one year. For this study, based on Oulu University Hospital's retrospective data (partly published in Pihlaja et al 2020) of venous ulcer healing the investigators assumed Hazard Ratio 1.5 for venous ulcer to heal in first-visit foam sclerotherapy group compared to scheduled treatment group. Assuming drop-out of 10% this study recruits total of 248 patients (a=0.05, b=0.2).
