BACKGROUND: We retrospectively analyzed the hospital mortality and neurologic outcome after surgery on the thoracic aorta with the aid of antegrade selective cerebral perfusion to determine a predictive risk model. METHODS: Between October 1995 and May 2002, 462 patients (mean age 62.7 +/- 11.7 years) underwent surgery on the thoracic aorta using antegrade selective cerebral perfusion. The indication for surgery was acute type A dissection in 132 patients (28.6%), degenerative aneurysm in 258 (55.8%), and post-dissection aneurysm in 72 (15.6%). One hundred and forty-one patients (30.5%) were operated on urgently; concomitant procedures were performed in 190 patients (41.1%). The mean cerebral perfusion time was 63 +/- 39 min. Predictors of hospital mortality and neurologic outcome were identified by univariate and multivariate analysis of the preoperative and intraoperative variables. RESULTS: The hospital mortality rate was 10.2%. Stepwise logistic regression identified an urgency status (odds ratio--OR 5.2, p = 0.001), a history of a central neurologic event (OR 4.1, p = 0.007) and coronary artery bypass graft (OR 3.2, p = 0.039) as being independent determinants for hospital mortality. The transient neurologic dysfunction rate was 6.2%. An urgency status (OR 3.4, p = 0.003) and a history of a central neurologic event (OR 5.1, p = 0.002) were independent determinants of transient neurologic dysfunction. An urgency status (OR 6.0, p = 0.011) was the only independent determinant for permanent neurologic dysfunction (3.8%). A cerebral perfusion time > 90 min was not associated with an increased risk of hospital mortality and permanent or transient neurologic dysfunction. CONCLUSIONS: Antegrade selective cerebral perfusion proved to be a safe method of brain protection allowing complex aortic repair to be performed with encouraging results in terms of hospital mortality and neurologic outcome.
