[Deep venous thrombosis of the right leg caused by compression by an abdominal aortic aneurysm].

A 67-year-old man was admitted because of suspected deep venous thrombosis of the right leg. At sonography, CT of the abdomen and aortography it became obvious that compression of the right iliac vein by an abdominal aortic aneurysm was responsible for the deep venous thrombosis. This has only been reported before twice. In the case of deep venous thrombosis or oedema of the legs an abdominal aortic aneurysm needs to be excluded.
