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 n ot well defined. We describe two cases of infrarenal aortic mural thrombus treated with thrombolytic therapy and review the published experience with this entity. (J Vasc Surg 2000;32:383-7.).
