Idiopathic pedunculated mural thrombus of the nonaneurysmal infrarenal aorta presenting with popliteal embolization: two cases treated with thrombolytic therapy.

The source of emboli to large or medium sized arteries is most commonly the heart; occasionally, it is an aortic aneurysm. The unusual embolic source of aortic mural thrombus in an otherwise minimally diseased aorta has been infrequently reported, and the etiology and management of this entity are not well defined. We describe two cases of infrarenal aortic mural thrombus treated with thrombolytic therapy and review the published experience with this entity.
