Venous Ulcer: Endovenous Radiofrequency Treatment Trial (VUERT)

Venous Ulcer: Endovenous Radiofrequency Treatment of Insufficient Perforating and Saphenous Veins Versus Multilayer Compression Bandaging - Randomized Controlled Clinical Trial

The aim of this study is to analyze the effect of intravenous therapy with radiofrequency for superficial and perforating venous insufficiency versus compression therapy with multilayer banding in patients with active venous ulcer. This is a controlled, randomized prospective clinical trial. People with venous ulcers and primary venous insufficiency in superficial and perforating venous system will be studied. Participants will be divided into two experimental groups: compression therapy alone, and compression therapy associated with superficial and perforating venous system ablation. Clinical aspects, improvement in patients' quality of life and interventions cost-effectiveness will be analyzed. Patients will be followed for 12 months after ulcer healing.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ulcer Healing - 12 w	Ulcers was already healed after 12 weeks	12 weeks
Ulcer Healing - 24 w	Ulcers was already healed after 24 weeks	24 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ulcer Recurrence	Ulcer recurrence rate after 1 year of follow up	1 year
Quality of life SF-36	Increasing in individual's quality of life using SF 36	at the begginning and up to 1 week after ulcer had healed
Quality of life EQ- 5D	Increasing in individual's quality of life using EQ-5D	at the begginning and up to 1 week after ulcer had healed
Quality of life VLU-Qol	Increasing in individual's quality of life using VLU-Qol	at the begginning and up to 1 week after ulcer had healed
Quality of life CCVLUQ	Increasing in individual's quality of life using VLU-Qol	at the begginning and up to 1 week after ulcer had healed
Health Economic Assessment	A cost-effectiveness analysis will be performed using the collected data of resources used in participants care along the study. Cost-utility (QALY) will be calculated using EQ-5d questionarie data	1 year
