RESUMEN
A 63-year-old man had undergone patch repair of a chronic dissecting thoracoabdominal aortic aneurysm 8 years previously. Postoperative course was uneventful during 8 years after the first operation. However follow-up CT scan 8 years after demonstrated pseudoaneurysm of thoracoabdominal aorta at the anastomotic side. Reoperation for pseudoaneurysm was performed through left thoracotomy under partial cardiopulmonary bypass. Pseudoaneurysm was revealed at the proximal anastomotic side. Graft replacement for thoracoabdominal aorta and reconstruction of two pairs of intercostal arteries and the celiac artery was performed under SEP and MEP monitoring. His postoperative course was uneventful. He was discharged from our hospital 12 days after surgery. Follow-up CT scan demonstrates no recurrence of pseudoaneurysm for 1 year after surgery.
