A CASE OF TYPE-A DISSECTION INVOLVING RIGHT AORTIC-ARCH

Aortic dissection involving right aortic arch (RRA) is quite rare, A p atient with RAA and aberrant left subclavian artery (type 3 RAA) devel oped type A dissection, but successfully underwent ascending and hemia rch replacement under hypothermic circulatory arrest with continuous r etrograde cerebral per fusion. We approached the lesion through a midl ine sternotomy and could reconstruct the first two arch vessels involv ed by the dissection. We would have added bilateral thoracotomy. if th e distal arch vessels had required reconstruction. To our knowledge, t his is the first report of successful surgical repair for type A disse ction involving RAA. (C) 1997 Elsevier Science B.V.
