Closure of a Thoracic Aortic Graft Pseudoaneurysm With an Amplatzer Septal Occluder

We describe the case of a young man 7 weeks postoperative from repair of a Stanford type A aortic dissection who developed an expanding pseudoaneurysm of the proximal graft anastomosis. Owing to the morbidity and mortality associated with reoperation, an interdisciplinary team of interventional cardiologists and cardiothoracic surgeons implanted an Amplatzer septal occluder device in a hybrid operating room, successfully excluding the defect from the true lumen of the aorta. This case highlights the utility of a team approach and creative thinking for the treatment of a pseudoaneurysm in a high-risk, recently postoperative patient.
