Objectives: Mechanochemical endovenous ablation is a novel technique for the treatment of great saphenous vein and small saphenous vein incompetence which combines mechanical injury of the endothelium with simultaneous infusion of liquid sclerosant. The main objective of this study was to evaluate early occlusion.
Methods: All consecutive patients who were eligible for the treatment with mechanochemical endovenous ablation were included. Inclusion period was from the introduction of the device in the hospitals (September 2011 and December 2011) until December 2012.
Results: A total of 449 patients were included representing 570 incompetent veins. In 506 treated veins, duplex ultrasonography was performed at follow-up: 457 veins (90%) were occluded at a follow-up of 6 to 12 weeks. In univariate and multivariate analysis, failure of treated great saphenous vein was associated with saphenofemoral junction incompetence (OR 4; 95% CI 1.0-17.1, P = 0.049).
Conclusions: The Clarivein device proves to be safe and had a high short-term technical effectiveness.
