Study summary

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).

Study population

500 patients with varicose veins, indicative for treatment with Endovenous laser ablation (EVLA) or Surgery (ligation/stripping) according to routine patient care.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Patient is at least 18 years old.
  2. Patient must sign and date the form prior to treatment.
  3. Presence of unilateral or bilateral primary or recurrent symptomatic varicose veins (CEAP grade ≥ C2).
  4. Patient has an insufficient Great Saphenous Vein (GSV), Anterior Accessory Saphenous Vein (AASV) and/or Small Saphenous Vein (SSV), with venous symptoms (valve incompetence).

Exclusion criteria

Exclusion Criteria:

  1. Current deep vein thrombosis.
  2. Acute superficial thrombosis.
  3. Pregnancy.
  4. Coagulopathy or bleeding disorders.
  5. to the use of general or regional anesthesia.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. 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

  2. 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.

    Time frame: At 6 weeks follow-up

Secondary outcomes

  1. Procedural characteristics

    Type of anesthesia

    Time frame: At index-procedure

  2. Procedural characteristics

    Number, type and length of veins treated

    Time frame: At index-procedure

  3. Procedural characteristics

    Total energy per patient and fiber (when using the ELVeS® Radial® 2ring slim fiber)

    Time frame: At index-procedure

  4. Procedural characteristics

    Number of procedures showing technical success, defined as the ability to treat the varicose veins as planned

    Time frame: At index-procedure

  5. Procedural characteristics

    Peri-operative adverse events (bleeding, incomplete treatment, technical defects, difficult visualization, ...)

    Time frame: At index-procedure

  6. Procedural characteristics

    Duration of the index-procedure

    Time frame: At index-procedure

  7. 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

  8. 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 6 weeks follow-up

  9. Anatomic success of EndoVenous Laser Ablation (EVLA)

    Defined as occlusion of the treated veins and lack of reflux objectified with duplex ultrasonography.

    Time frame: At 6 weeks follow-up
