From January 1989 to July 1995, 18 patients underwent aortic repair for type A dissections. There were 9 male and 9 female patients aged 41 to 68 years(mean, 53.8). Thirteen patients underwent the procedure during the acute period, and 5 during
the
chroic period. During repair of acute dissection, procedures included graft replacement of the ascending aorta only(6 patients), ascending aorta plus partial aortic arch(3), ascending aorta plus total aortic arch(2), Bentall's operation(1), and
Bentall's operation plus total aortic arch(1). During repair of chronec dissection, procedures included Bentall's operation(3 patients), ascending aorta only(1), and ascending aorta plus partial aortic arch(1). During repair of the arch,
antegrade
cerebral perfusion was applied in 4 patients and hypothermic circulatory arrest in 3 patients. There were 4 operative deaths(22.2%), 2 of hemorrhage and 2 of left ventricular failure in the operating room. Follow-up has been 100% completed and
ranged
from 2 to 53 months(mean, 17 months). One late death resulted from sepsis following second operation. Thirteen of the survivors are doing well.
