Three Cases of Lower Extremity Thromboembolism Suspected to be Caused by Aortic Mural Thrombus

Abstract

　Aortic mural thrombus is an uncommon cause of peripheral arterial thromboembolism. We present three cases of lower extremity thromboembolism due to aortic mural thrombus. All cases were treated with anticoagulant therapy. Endovascular therapy with a stent graft was performed in one case. Thromboembolism recurred in one case due to the interruption of anticoagulant therapy. The treatment of aortic mural thrombus is controversial. Recently, endovascular therapy with a stent graft has been reported. In all cases, thromboembolism did not recur during anticoagulant therapy. Endovascular or surgical therapy is recommended when thromboembolism recurs, or thrombi grow with anticoagulant therapy.
