Brief Summary:

Varicose veins affect a majority of adult patients and cause a decreased quality of life. In recent years, standard practice has been to perform thermoablation and local phlebectomies in the same procedure. There is conflicting data on the long-term outcome of the local varicose veins; there seems to be a need for more re-interventions if the local varicosities are not treated immediately. On the other hand, the prolonged combined procedure increases procedural pain and bleeding, as well as the risk for complications from deep vein thrombosis/pulmonary embolism.

This trial aims to evaluate the need for immediate treatment of local varicosities and the potential sufficiency of main trunk treatment.

Arm Intervention/treatment
Active Comparator: Immediate phlebectomy
Mechanochemical ablation of main trunk and immediate phlebectomy of varicosities
Procedure: Immediate phlebectomy
See arm description

Experimental: Delayed treatment
Mechanochemical ablation of main trunk. Evaluation of varicosities at 3 months with sclerotherapy if required
Procedure: Delayed sclerotherapy
See arm descriptions




Primary Outcome Measures :
  1. Need for sclerotherapy [ Time Frame: 3 months ]
    Need for sclerotherapy of varicosities at three months after ablation of main trunk. Evaluated by the CEAP-classification of venous insufficiency. >C2 will be eligible for treatment.


Secondary Outcome Measures :
  1. Patient satisfaction [ Time Frame: 3 months ]
    Overall patient satisfaction and symptoms regarding varicosities and procedure at three months. Evaluated by the Aberdeen Varicose Veins Questionnaire (AVVQ). The AVVQ is a validated test, in which patients are asked to check boxes with regard to symptoms and quality of life (QoL). Scale 0-100, with 100 indicating worst possible QoL.

  2. Occlusion rate of great saphenous vein [ Time Frame: 36 months ]
    Long-term occlusion rate of main trunk after mechanochemical ablation, evaluated by duplex ultrasound.
