About this study

Official title: Management of Tributary Veins in Superficial Venous Insufficiency of the Lower Limbs: Impact of Endovenous Steam Treatment Versus Phlebectomy on Quality of Life

The prevalence of superficial chronic venous insufficiency (CVI) of the lower limbs is estimated at 18 million French people. The number of patients operated for varicose veins is around 300,000 per year. Post-operative complications such as venous ulcer, venous thrombosis and varicose vein rupture require a lot of medical care. Varicose veins are responsible for a decrease in quality of life and represents 1 to 2% of total health expenditure.

Currently, operating techniques tend towards minimally invasive procedures in order to minimize the surgical trauma, improve patient comfort and reduce the time of postoperative work stoppages.

This study aims to compare two surgical techniques for the treatment of superficial chronic venous insufficiency of the lower limbs : phlebectomy, the gold-standard technique, and endovenous steam treatment. Several studies have already been carried out on endovenous steam treatment for saphenous veins but none has been published concerning the tributary veins.The main objective of INVOLVE is to assess the quality of life of patients 1 month after surgery. Clinical improvement and economic impact will also be evaluated.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of the quality of life relative to the health of patients after endovenous steam treatment versus phlebectomy of the tributary veins

    Questionnaire : VEnous INsufficiency Epidemiological and Economic Study on Quality of Life/Symptoms (VEINES-QOL/Sym) : target dimension " VEINES-QoL symptom summary score ". High values indicate better outcomes.

    Measured: one month after the intervention

Secondary outcomes (3)
  1. Comparison of the evolution of the quality of life relating to health of patients after endovenous steam treatment versus phlebectomy of the tributary veins

    Questionnaires : VEnous INsufficiency Epidemiological and Economic Study on Quality of Life/Symptoms (VEINES-QOL/Sym), 36-Item Short Form Survey Instrument (SF36).

    The scores range from zero where the respondent has the worst possible health to 100 where the respondent is in the best possible health.

    Measured: 8-15 days, 3, 6, 9 and 12 months after the intervention

  2. Comparison of occlusion of the tributary veins after endovenous steam treatment versus phlebectomy of the tributary veins

    Occlusion rate evaluated by Doppler ultrasound

    Measured: 8-15 days and one year after the intervention

  3. Evaluation of the period of resumption of activity for people in activity after endovenous steam treatment versus phlebectomy of the tributary veins

    Duration of work stoppage for working people

    Measured: up to 1 year

Questions about this trial

What is this clinical trial studying?

A study testing VBox Hybrid in people with Venous Insufficiency of Leg, run by Centre Hospitalier Universitaire de Besancon.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of the quality of life relative to the health of patients after endovenous steam treatment versus phlebectomy of the tributary veins (time frame: one month after the intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024.
