Thoracic Endovascular Aortic Repair for Ruptured Intercostal Patch Aneurysm Following Thoracoabdominal Aortic Aneurysm Repair.

Aneurysmal change of reconstructed intercostal arteries is believed to be a rare complication after thoracoabdominal aortic repair. To our knowledge, there is no guideline or randomized controlled trials regarding intercostal patch aneurysm management. Therefore, the optimal treatment is still controversial. We describe a successful case of emergent thoracic endovascular aortic repair for ruptured intercostal patch aneurysm in an 83-year-old man following thoracoabdominal aortic aneurysm repair. Our experience illustrated that gradual expansion of large blocks of aortic wall reconstruction should be closely monitored after primary thoracoabdominal aortic replacement.
