A case of type A dissection involving right aortic arch.
Aortic dissection involving right aortic arch (RAA) is quite rare. A patient with RAA and aberrant left subclavian artery (type 3 RAA) developed type A dissection, but successfully underwent ascending and hemiarch replacement under hypothermic circulatory arrest with continuous retrograde cerebral perfusion. We approached the lesion through a midline sternotomy and could reconstruct the first two arch vessels involved by the dissection. We would have added bilateral thoracotomy, if the distal arch vessels had required reconstruction. To our knowledge, this is the first report of successful surgical repair for type A dissection involving RAA.
