Successful management of huge floating thrombus within aortic arch in a patient with old myocardial infarction

Few cases of a floating thrombus in an aorta have been reported without any systemic embolic complications. We report an unusual case of a huge floating thrombus (3 cm × 10 cm in size) in the aortic arch. The patient had a history of old myocardial infarction and had undergone successful percutaneous coronary intervention 16 years previously. The aortic thrombus was detected incidentally after echocardiography and computed tomography without any evidence of aortic dissection or distal embolization. The huge thrombus was removed successfully from the aortic arch by urgent surgery.
