Abstract

69-year-old woman with hypertension and hyperlipidemia was referred to our hospital because of suspected acute ischemia of the right lower limb. Physical examination revealed bilateral pain and paleness of the lower limbs, paresthesia and paralysis of the right lower limb and an ulcer between the fourth toe and fifth right toe. Computed tomography (CT) showed occlusion of the right popliteal artery and an irregular lesion of the descending aorta, which was suspected to be a thoracic aortic thrombus. We performed an emergency thrombectomy because of acute arterial occlusive disease of the right lower limb. After the thrombectomy, due to recurrent emboli, we performed descending aorta replacement because of recurrent emboli despite anticoagulant therapy. The pathological diagnosis was intimal angiosarcoma of the thoracic aorta. In this case, we presumed that acute arterial occlusive disease of the lower limb was caused by an intimal angiosarcoma.
