[Mural thrombosis of the abdominal aorta. A sometimes unrecognized cause of recurrent embolisms]

A 23 year old patient with an infrarenal abdominal aorta mural thrombosis developed recurrent peripheral emboli. This case underlines the etiologic investigation necessary in cases of peripheral emboli unexplained by the conventional cardiac examinations. Filling of total aorta with contrast is essential (assisted if necessary by oblique projections) to detect possible mural thrombi carrying the risk of recurrent emboli.
