Klippel Trenaunay syndrome in a 3-year-old: A case report

INTRODUCTION AND IMPORTANCE: Klippel-Trenaunay syndrome (KTS) is characterized by a triad of port-wine stain, varicose veins and soft tissue or bony hypertrophy of lower limb. Varicose veins in Klippel Trenaunay syndrome are mostly distributed in the lateral aspect of the lower limb. The exact etiology of KTS is not known, and the treatment usually starts with conservative management- limb elevation, compression stockings and physiotherapy. However, some cases are severe enough to warrant surgical management. CASE PRESENTATION: Here we present a case of a 3-year-old male child with clinical features suggestive of Klippel Trenaunay Syndrome managed successfully with sclerotherapy of persistent lateral marginal vein of servelle. At one month follow-up the vein was sclerosed and there was a significant reduction in varicosities of leg. CLINICAL DISCUSSION: Starting treatment of varicose veins in Klippel Trenaunay Syndrome in children is effective in preventing long-term complications in adults. Thus, treating venous malformation with sclerotherapy is warranted in early childhood to prevent venous hypertension and chronic venous insufficiency. CONCLUSION: Varicose veins in KT syndrome can be managed successfully by sclerotherapy of lateral marginal vein of servelle resulting in significant reduction in varicosities of leg.
