Abstract:
We present two operative cases of thoracic aortic aneurysm combined with aberrant right subclavian artery (ARSA). Case 1 was a 71-year-old man with a fusiform-type arch aneurysm. He underwent total aortic arch replacement to reconstruct all 4 arch branches. Case 2 was a 39-year-old man suffering from chronic DeBakey type IIIb dissection. He underwent total descending thoracic aortic replacement for the remaining ARSA. In both cases ARSA was diagnosed preoperatively by reconstructed three-dimensional computed tomography (3D-CT). Both patients followed uneventful postoperative courses with excellent results. 3D-CT is helpful for precise planning of surgical strategy in such cases.
