Pulmonary embolism in a patient with Klippel-Trenaunay-Weber syndrome.

Klippel-Trenaunay-Weber syndrome (KTWS) is a congenital disorder characterized by cutaneous capillary malformations, venous-lymphatic anomalies, hypertrophy of soft tissue and bone in the area of increased vascularity and arteriovenous fistulas with shunting. In this article we report the case of a 25 year old man with KTWS who had multiple surgical operations because of arteriovenous malformations. He admitted with pulmonary embolism attack to the hospital although he was taking prophylactic heparin treatment.
