The ClariVein device using 2% and 3% liquid Polidocanol for the treatment of great saphenous vein incompetence

Our study tries to identify the ideal sclerosant dosage for the ClariVein® system in order to occlude the GSV permanently. By choosing the lowest dose with the same anatomical success rate, we achieve a safe treatment which also gives us the…

Registry of the treatment of primary insufficiency of the great saphenous vein with a diameter >/= 12 mm, antero-lateral branches, or great saphenous vein insufficiency below the knee with mechano-chemical endovenous ablation (MOCA)

The goal of this registry study is to provide insight in the safety and efficacy of treatment with MOCA for primary insufficiency of the GSV with a diameter >/=12mm, insufficient antero-lateral branches (<12 mm) and insifficincy of the…

Endovenous laser ablation versus mechano-chemical endovenous ablation in the treatment of great saphenous incompetence: a multicentric, randomized controlled trial

The Clari-laser study is designed to evaluate the following questions: 1. What is the succes rate of MECEA versus EVLA on short and long term? 2. Are the results after treatment both clinically and technically comparable? 3. What are the per-and…

Parva II Trial: Randomized unicentre trial of re-crossectomy vs (repeated) ultrasound guided foam sclerotherapy of recurrence after crossectomy of the small saphenous vein

To compare the success rate and the occurrence of complications of re-crossectomy and (repeated) UGFS for the treatment of recurrence of the SSV for a period of 5 years.
