An observational study in Varicose Veins, sponsored by Duomed. Completed at 1 site in Belgium. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-09-05.

The goal of this registry is to evaluate the indication for EndoVenous Laser Ablation (EVLA) therapy. Can this be enhanced? What are the reasons for not using the laser? Therefore, this study aims to define clear indications for EVLA by registering the incentives of the participating investigators to use the laser instead of conventional corrective surgery for the treatment of varicose veins, at baseline and post-operative. Additionally, the efficacy and safety of the different varicose vein treatments will be evaluated by registering procedural characteristics, anatomic outcome (duplex ultrasound), quality of life (AVVQ) and postoperative pain (VAS).
500 patients with varicose veins, indicative for treatment with Endovenous laser ablation (EVLA) or Surgery (ligation/stripping) according to routine patient care.
Exclusion Criteria:
Patients with varicose veins, indicative for treatment with EndoVenous Laser Ablation (EVLA) using the ELVeS® Radial® 2ring slim fiber or Surgery (ligation/stripping) according to the standard of care of the participating investigators.
Device: ELVeS® Radial® 2ring slim fiber used for EndoVenous Laser Ablation
Device for endovenous laser ablation manufactured by Biolitec AG company (ELVeS system) - diode laser with a wavelength of 1470 nm
To define clear indications for EndoVenous Laser Ablation (EVLA) treatment of varicose veins.
The participating investigators will register the incentives (based on clinical examination and/or anatomic outcome by duplex ultrasound, as well as secondary considerations) to use laser ablation or conventional treatment for varicose veins in the study database in order to define clear indications for EndoVenous Laser Ablation (EVLA) treatment of varicose veins and to investigate whether the use of EVLA can be enlarged.
Time frame: At baseline
To define clear indications for EndoVenous Laser Ablation (EVLA) treatment of varicose veins.
The participating investigators will re-evaluate the chosen treatment option and document this re-evaluation in the study database in order to define clear indications for EndoVenous Laser Ablation (EVLA) treatment of varicose veins and to investigate whether the use of EVLA can be enlarged.

Pain scoring using the Visual Analog Scale (VAS)
The VAS scale contains a 0 - 100 grading with 0 equaling no pain and 100 equaling the worst conceivable pain. The patient is asked to select the number on the scale that corresponds to the worst level of pain he/she experiences. Pain is classified into mild (1 - 30 mm), moderate (31 - 60 mm) and severe (61 - 100 mm). Absence of pain is defined as VAS = 0.
Time frame: At discharge, up to 1 week

Anatomic success of EndoVenous Laser Ablation (EVLA)
Defined as occlusion of the treated veins and lack of reflux objectified with duplex ultrasonography.

Quality of life by scoring Aberdeen Varicose Vein Questionnaire (AVVQ)
Aberdeen Varicose Vein Questionnaire (AVVQ) is a validated tool for assessing the perceived health of patients with varicose veins. The AVVQ comprises 13 quality of life questions, including a set of manikin legs, on which participants are asked to draw their veins.
