Endovascular management of a mobile thoracic aortic thrombus following recurrent distal thromboembolism: a case report and literature review.

Sources of lower extremity and visceral arterial thromboembolism most commonly include the heart and proximal aneurysmal disease. Infrequently, further workup of "cryptogenic" emboli will reveal a mural atheroma or thrombus of the descending thoracic aorta. Without prospective data, anticoagulation and open surgical thrombectomy with or without aortic replacement have been the standard approach. Presented is a case of a floating mural thrombus in the setting of superior mesenteric and femoral arterial thromboembolism that was effectively treated with endovascular stent graft exclusion.
