Klippel Trenaunay Syndrome (KTS)
KTS is a very congenital condition in which the deep venous system in the leg(s) failed to properly develop leaving only the superficial system as a means of returning blood up to the level of the pelvis. It can occur in discrete or skipped areas or involve the whole leg. These results in a massive enlargement of the superficial and reticular venous system with tell tale large dark blue and red venous splotchy varicosities which increase as the child grows older and results in bone overgrowth and a swollen and deformed and elongated leg. This is a very complex condition which requires referral to a specialty hospital or university center.
