RESUMEN
The pseudoaneurysm of the aorta is rarely due to trauma and infection but usually is a late complication of previous surgical procedures like coronary artery bypass graft surgery. We describe a 65-year-old woman with the pseudoaneurysm of the ascending aorta due to coronary artery bypass graft surgery. It was revealed in coronary artery angiography after nonspecific symptoms. It was confirmed by multidetector computed tomographic angiography. The patient refused open cardiac surgery, so we decided to use an atrial septal defect occluder device in off-label way to seal the pseudoaneurysm orifice. In a hybrid operating room setting, the procedure was done successfully and patient's hospitalization course was eventless. In multidetector computed tomographic angiography after 3 months, the device was in the appropriate position without endoleak and in the yearly visit the patient was asymptomatic and healthy
