Purpose or Case Report: The lateral marginal vein, a persistent embryonic vein found in Klippel-Trenaunay (KT) patients, can be a major cause of morbidity such as venous hypertension and venous thromboembolism. Our purpose is to report our experience embolizing the lateral marginal vein using the Clarivein^TM device, a pharmacomechanical embolization system.
Methods & Materials: Retrospective review of PACS and EMR for KT patients undergoing treatment of their lateral marginal vein using the Clarivein^TM device. Patient demographics, technical details of the procedure, and follow up imaging was collected.
Results: Four KT patients underwent four procedures to embolize the lateral marginal venous system. Technical success was 100% and there were no complications related to the embolization. Two of the four patients underwent additional therapies at the same time including sclerotherapy for venous and lymphatic malformations. Three of the four patients had ultrasound follow up that demonstrated complete occlusion of the treated venous segment. One patient had partial recanalization on further follow up one month after the procedure and underwent laser ablation which was also only partially successful.
Conclusions: Embolization of the lateral marginal venous system with the Clarivein^TM device may be a good option for effective treatment.
