Interventions
|
Group A : Endovenous Laser Treatment (EVLT): EVLT of the great saphenous vein is performed with an 810 nm Diode laser (bare fibers) using Seldinger's technique ultrasound guided under tumescent local anaesthesia. The energy dose is intended to be 20 J/cm² delivering 20 W laser power. The additional phlebectomy of side branches is allowed.
Group B : High Ligation (Crossectomy) and Stripping (HLS): Standard surgical procedures are performed, consisting of transection of all groin tributaries, flush ligation of the saphenofemoral junction with non-resorbable sutures and neoreflux protection with a continuous stump suture, followed by invagination stripping of the great saphenous vein just below knee under tumescent local anaesthesia. The additional phlebectomy of side branches is allowed.

|
Primary outcome measure(s)
|
Recurrent varices after surgery (REVAS) evaluated at 12 and 24 months follow up visit.
|
|
Secondary outcome measure(s)
|
1. Duplex recurrence
2. Side effects
3. Homburg Varicose Vein Severity Score
4. Chronic Venous Insufficiency Questionnaire
5. Venous Refilling time (DPPG)
6. Patients' satisfaction is measured using visual analogue scale based questionnaires
Follow-up visits are scheduled in the first postoperative week (side effects), at 3 months [side effects, Homburg Varicose Vein Severity Score (HVVSS), Chronic Venous Insufficiency Questionnaire (CIVIQ), Venous refilling time (DPPG), patient's satisfaction], at 12 months [Duplex recurrence, HVVSS, CIVIQ, DPPG, patient's satisfaction] and at 24 months (Duplex recurrence, HVVSS, CIVIQ, DPPG, patient's satisfaction)
