Factors associated with delayed venous ulcer healing after endovenous intervention for superficial venous insufficiency.

Objective: This retrospective trial analyzed the effect of predetermined variables on venous ulcer healing after endovenous ablation of insufficient veins.

Methods: A total of 259 patients presenting 273 venous leg ulcers (VLUs) at Oulu University Hospital vascular outpatient clinic between January 2010 and December 2020 were included in the study. In addition to compression therapy, all patients received endovenous ablation (endothermal ablation and/or foam sclerotherapy) to promote venous healing.
