[Long-term results after surgery for aortic arch nondissection aneurysm].

Between 1990 and August 2001, 109 patients were treated surgically for nondissection fusiform or saccular aortic arch aneurysm. Fifteen patients were emergent. There were 89 male and 20 female patients (mean 71.7 +/- 6, range 49 to 84). Eight patients underwent hemiarch replacement, 57 total arch replacement, 44 distal arch replacement, which were performed with the aid of hypothermic extracorporeal circulation with antegrade selective cerebral perfusion or retrograde cerebral perfusion. The early mortality was 8.5% with elective operations and 53.3% with emergent operations. The incidence of post operative permanent neurological dysfunction was 12.8% with elective operations and 46.7% with emergent operations. The 5-year and 10-year survival rate including in-hospital deaths was 52 +/- 6% and 29 +/- 9%. The 5-year event free rate was 89 +/- 5%.
