About Klippel-Trenaunay Syndrome
Klippel-Trenaunay syndrome is a congenital vascular malformation characterized by abnormal venous growths, commonly presenting as a port-wine birthmark on a limb. Patients may experience both surface vein malformations, such as varicose veins, and deeper vein issues that increase the risk of serious complications like deep vein thrombosis. Symptoms also include abnormal limb growth, heaviness, mobility issues, and in rare cases, digit fusion or additional digits.

About Klippel-Trenaunay Syndrome

- 2. Introduction Since 2005,Dr. Mitar Vranic has cared for patients at Arizona's Western Vascular Institute. There, Dr. Mitar Vranic treats vascular conditions ranging from venous insufficiency to Klippel-Trenaunay Syndrome. A congenital malformation of the blood vessels, skin, and soft tissue, Klippel-Trenaunay Syndrome typically makes itself known through the appearance of abnormal venous growths. The majority of patients with the syndrome are born with a port-wine birthmark, pink to red in color and created by the swelling of blood vessels near the skin. In most patients, it extends over the majority of one limb. Similarly, Klippel-Trenaunay Syndrome causes malformation of both surface and deep veins. Surface vein malformations often present as varicose veins, which have a twisted and enlarged appearance.

Klippel-Trenaunay Syndrome Malformationsin deeper veins may be less aesthetically obvious but can be more dangerous, as they increase a patient's risk of a blood clot known as deep vein thrombosis (DVT). This condition is potentially fatal, as material from the clot may break off and travel to the lungs, where it can cause a pulmonary embolism (PE). Patients with Klippel-Trenaunay Syndrome also experience abnormal growth in a limb or limbs, though the rare patient experiences these symptoms in the trunk. Patients typically report feelings of heaviness and trouble with movement, as well as pain. In some cases, excessive growth of one leg causes difficulty walking. Less common signs include the fusion of digits or growth of extra fingers or toes.
