ABSTRACT
We report a case of chronic DeBakey type I dissecting aneurysm with an aberrant right subclavian artery, in which replacement of the ascending aorta and the transverse aortic arch was performed under selective cerebral perfusion, resulting in complete obliteration of the false channel in the descending thoracic aorta. A 57-year-old female was admitted to our service complaining of chest and back pain. An aberrant right subclavian artery that originated from the descending thoracic aorta was identified. During operation, the dissected aortic wall of the aortic arch and the proximal descending thoracic aorta that involved more than half of its circumference was resected, the dissected intima was reapproximated at the distal stump, and the beveled distal end of the tubular ascending aortic prosthesis was secured to the cut edge. The postoperative course was uneventful, and she is leading a normal life now four years after surgery. It is rare to reconstruct the aortic arch for aortic dissection that occurred in a patient with aberrant right subclavian artery, and the technical details were reported.
