Aims The purpose of this retrospective study was to assess the risk factors for the early and late outcome of the surgical treatment of acute type A aortic dissection, in terms of mortality and morbidity.
Methods and results From 1976 to 2003, 487 patients with acute type A aortic dissection treated surgically were enrolled. Twenty-five pre-operative and intra-operative variables were analysed to identify conditions influencing early and late morbidity and early mortality. The in-hospital mortality rate including operative death was 22% (107 patients). Multivariable analysis indicated that pre-existing cardiac disease (RR=3.7, 95% CI=1.87.4) and cardiopulmonary resuscitation (RR=6.8, 95% CI=2.320.2) were independent predictors of in-hospital death. The causes of in-hospital mortality were low cardiac output in 32 patients (6.6%), major brain damage in 24 patients (5.9%), haemorrhage in 11 patients (2.2%), sepsis in nine patients (1.8%), visceral ischaemia in eight patients (1.6%), multiple organ failure in seven patients (1.4%), rupture of the thoracic aorta in six patients (1.2%), respiratory failure in six patients (1.2%), and four intra-operative deaths. The follow-up was 100% complete. The actuarial survival was 94.9±1.2% and 88.1±2.6%, at 5 and 10 years, respectively.
Conclusions Patients' pre-operative co-morbidities and dissection-related complications significantly affect early and late survival and morbidity after surgical treatment of acute type A aortic dissection.
