Background: Our surgical strategies for acute type A aortic dissection (AAAD) are prompt establishment of cardiopulmonary bypass and primary entry resection. We investigated our experience with surgery for AAAD. Methods: Between January 1997 and December 2006, 243 consecutive patients with AAAD underwent emergency surgery. Clinical and diagnostic data of these patients were analyzed retrospectively. Results: Surgical procedures included ascending aorta or hemiarch replacement (n = 212) and total or partial arch replacement (n = 31), and those for proximal reconstruction included modified Bentall procedure (n = 8), and aortic valve replacement (n = 3). Hospital mortality was 6.9%, and entry resection was performed in 74% of patients. Actuarial survival rate at 5 and 10 years was 86% ± 14% and 77% ± 23%, respectively. A total of 13 patients required re-operation: 5, an aortic root; 3, an aortic arch; and 5, a descending aorta. Actuarial freedom from re-operation at 5 and 10 years was 95% ± 5%, and 81% ± 18%, respectively. Conclusions: Our surgical strategy for AAAD seems to be pertinent with acceptable shortand long-term results. Since we lost 8 patients due to rupture of false lumen postoperatively, careful follow-up for a residual false lumen may improve the patients' prognosis.Keywords: aortic dissection, aortic operation, outcomes, aortic reoperation Ann Thorac Cardiovasc Surg 2012; 18: 18-23 doi: 10.5761/atcs.oa.11.01704 have shown that a more aggressive technique, such as the routine replacement of a total arch, have resulted in better long-term outcomes by the elimination of the residual, patent false lumen.
3,5-7)However, we believe that priority of the patient with AAAD is immediate survival, which may be accomplished by simple and less invasive operative procedures, rather than risking further aggression for already risky patient through extended surgery. Simple and less invasive operative procedures that we recommend include prompt establishment of cardiopulmonary bypass to prevent malperfusion, preservation of the aortic valve whenever possible, and aortic arch replacement in patients with an entry site located in or extending into the aortic arch. This study investigated our early and late surgical results of AAAD to validate our surgical strategy for AAAD.
