What Is Klippel Trenaunay Syndrome?
2. Varicose Veins
Varicose veins are veins that become enlarged and twisted due to increased venous pressure. This condition is fairly common and is mostly caused by venous insufficiency, which simply means that there is a problem (i.e. weak or damaged venous valve) that causes the blood in certain veins to flow backward and accumulate. This causes veins to stretch or twist, and depending on the severity it can be either cosmetically disfiguring and uncomfortable or produce systemic consequences.
For different causes, in people with KTS, varicose veins are present since birth (congenital); however, most may not be evident until the infant starts to walk. They can be fairly extensive, affecting the lower extremities and the pelvic region. Moreover, pain and lymphedema (swelling due to build-up of lymph fluid in the extremity) have also been reported by patients with KTS. Furthermore, there can be a large and lateral superficial vein present at birth, known as the Klippel-Trenaunay vein. It usually runs from the foot or lower leg to the thigh or gluteal region.
