Groningen: Mechanochemical endovenous ablation is a new technique, whereby a varicose vein is closed off using a catheter with a rotating wire in combination with sclerotherapy. The treatment is both safe and effective, and patients suffer less pain during and after the procedure than with the current thermal techniques. They recover more quickly and are able to resume work sooner. These are the results of research by UMCG PhD candidate Ramon van Eekeren, who works as a surgeon in Arnhem. He will defend his thesis on 1 April at the University of Groningen.
