[True aneurysm of the ascending aorta and/or aortic arch; determinants of late surgical outcome].
To identify significant predictors of late mortality, multivariate analysis were applied to the clinical outcome of 150 consecutive patients with true aneurysm of the ascending aorta and/or aortic arch operated between January, 1987 and December, 2000. Mean follow-up was 53.0 months with a total of 6,682 patient-months of follow-up. Multivariate analysis revealed that operation date (before December, 1996), presence of preoperative cerebrovascular disease, rupture and postoperative phrenic nerve palsy were independent determinants of late mortality. The overall 5-year and 10-year actuarial survival rates were 66.0% and 48.2%. The 5-year and 10-year event free rate of cardiovascular and/or cerebrovascular death were 88.9% and 71.7%. Preoperative evaluation of the brain, operation prior to aneurysm rupture and phrenic nerve protection during operation is necessary to improve long-term survival rate.
