Repair of acute type A aortic dissection: results in 100 patients

Abstract

To determine short- and long-term outcomes after repair of type A aortic dissection, we reviewed data of 100 consecutive patients (64 men; mean age, 63 ± 12.2 years) who underwent acute type A aortic dissection repair between January 2000 and June 2008. They were divided into group A, open anastomosis (circulatory arrest; n = 59) and group B, closed anastomosis (no circulatory arrest; n = 41). Aortic valve re-suspension or replacement was performed in 77 patients, aortic root replacement in 29, and aortic arch procedures in 31. The median follow-up was 2.8 years (range, 0-8.6 years). The 30-day mortality was 14%; 16.9% in group A and 9.8% in group B. None of the 23 variables analyzed to determine predictors of death or stroke was significant on multivariate analysis. Postoperatively, there was no difference between the 2 groups with respect to stroke, sepsis, renal failure, multiorgan failure, or reoperation. Overall actuarial survival at 1, 3, 5, and 8 years was not significantly different between the 2 groups. Considerable morbidity is still associated with repair of type A aortic dissection, despite a significant improvement in mortality.
