Background: Klippel–Trenaunay syndrome (KTS) and related overgrowth syndromes are rare conditions that often present to academic pediatric units and multidisciplinary vascular anomaly clinics. These conditions are commonly associated with abnormalities of the superficial and deep venous structures and carry an increased risk of venous thromboembolism. Methods: A retrospective chart review was completed of all patients treated at Johns Hopkins All Children's Hospital with endovenous laser ablation therapy (EVLT) for management of dilated embryonic veins in the setting of limb overgrowth. Results: Three patients with limb overgrowth underwent EVLT between 2015 and 2017. All patients had successful occlusion of the targeted veins on post-procedure imaging. One patient developed a cellulitis successfully treated with oral antibiotics. Conclusions: Endovenous laser ablation therapy is a well-tolerated and safe procedure for prophylactic closure of abnormal superficial embryonic veins. This study supports the use of this technique in managing increased thromboembolic risk in this unique patient population and recognizes the need for a long-term study to determine its efficacy.
