Résumé
We recorded a case of a 58-year-old man who presented with swelling of the right neck after sudden chest pain. He was diagnosed with Stanford type A aortic dissection. Computed tomography revealed an aneurysm in the innominate artery surrounded by a hematoma. We therefore suspected a rupture of the innominate artery. In addition, the right common carotid artery was almost completely obstructed due to dissection. An emergency partial arch replacement was performed. Cardiopulmonary bypass (CPB) was established with two blood supplies : the right axillary and left common femoral arteries. When CPB was started, the innominate artery ruptured and could no longer be used for cerebral perfusion or as an anastomotic site. The right side of the neck was opened, and a synthetic graft was anastomosed to the right common carotid artery for cerebral perfusion. Finally, the graft was anastomosed with a branch of the main trunk. The right subclavian artery was also reconstructed using a graft that was anastomosed to the axillary artery for blood supply. The postoperative course was favorable, and no cerebral complications were observed.
