Study Arms:
- EndoVenous Laser Ablation (Type: ACTIVE_COMPARATOR): EndoVenous Laser Ablation (EVLA) involves the delivery of laser light through a glass fibre placed into the lumen of a refluxing vein. This energy is converted into heat inducing a permanent, non-thrombotic occlusion.
- MechanoChemical Ablation (ClariVein®) (Type: ACTIVE_COMPARATOR): Mechanochemical ablation (MOCA) is performed by a device called ClariVein® which is a long thin catheter that is passed up inside the vein, with a rotating wire that protrudes at an angle from the end when deployed. This is motorised via an electric motor in the handle and rotates at approximately 3500 revolutions per minute. In addition, liquid sclerotherapy is injected at the handle end by a syringe. This sclerotherapy liquid emerges from the end of the catheter and is present in the area of the rotating tip.

Based on this trial design, predict the completion outcome and termination type (if applicable).
