The Use of Endovenous Laser Treatment in Toddlers

The use of endovenous laser ablation therapy in children is limited. Klippel-Trenaunay syndrome (KTS) is associated with persistent ectatic anomalous veins within the affected extremity, with increased risk of thromboembolism. The present report describes four toddlers (<20 kg) with KTS of the lower extremity who underwent a total of five endovenous laser procedures for treatment of ectatic anomalous marginal venous system, without complications.
