Klippel–Trenaunay Syndrome: Employment of a New Endovascular Treatment Technique—Mechanochemical Ablation Using the Flebogrif System

Background: Klippel–Trenaunay syndrome (KTS) is characterized by a triad of symptoms; varicose veins and venous malformations (VMs), capillary malformations (port-wine stain), and soft tissue and bone hypertrophy. Herein, we retrospectively studied six patients with KTS who underwent treatment with the Flebogrif system and evaluated their outcomes. Methods: Six KTS patients aged 16–22 years who had undergone 18 non-thermal ablations using the Flebogrif system were enrolled. All patients underwent multistage foam sclerotherapy with 3% polidocanol at 3–4-week intervals. Results: Venous clinical severity score (VCSS) analysis showed improvement in the patients’ clinical condition. All patients reported a significant improvement in aesthetic outcomes. One patient presented with recanalization of ablated marginal veins during the 24-month follow-up period. Patients could return to full activity within 7–10 days after the procedure. None of the patients experienced serious systemic complications. Conclusion: The use of the Flebogrif system in treating various forms of chronic venous insufficiency, including in patients with KTS, provides a high success rate with a high closure rate.
