The Vascular Surgeons of Western Vascular Institute have over two decades of specialized experience providing care to individuals with Klippel-Trenaunay syndrome (or KTS). KTS is a rare genetic condition, Klippel-Trenaunay syndrome is characterized by abnormal growth of blood vessels, bone, and soft tissue. The majority of patients with the syndrome present at birth with a red-purple birthmark, which typically appears on a leg and stems from the swelling of small vessels near the skin’s surface. In some patients, the birthmark develops small blisters that are prone to bleeding.
