Abstract
A 75-year-old male with an aneurysm in the transverse aortic arch with aberrant right subclavian artery was surgically treated successfully. Preoperative angiograms suggested abnormal expansion of neck vessels but this was not confirmed before operation. At operation, right aberrant subclavian artery was confirmed and the transverse aortic arch was replaced with a 22mm woven Dacron graft and four brachiocephalic vessles were reconstructed by interposition of four 8mm Dacron grafts between those vessels and the arch prosthesis. The postoperative course was uneventful and the postoperative angiograms indicated successful transverse aortic arch reconstruction.
