BACKGROUND: Risk of repairing aortic dissection after previous cardiovascular surgery has not been described clearly. This study assesses early and late outcomes of such reoperations.
METHODS: From January 1, 1990, to January 1, 2002, 108 patients with prior cardiovascular surgery (isolated coronary artery bypass grafting, 51%; isolated valve surgery, 21%; aortic aneurysm repair, 24%; and combinations of these in the remainder) underwent reoperation for aortic dissection (emergency operation for acute dissection in 24%). Mean age was 63 +/- 13 years, and 85% were men. The interval since prior surgery ranged from 10 days to 22 years (median, 3.8 years). This was the third operation for 8%. Ascending aortic repair with or without aortic arch or descending aortic repair was performed in 40%, aortic valve replacement (n = 15) or repair (n = 17) with ascending aortic repair in 30%, aortic root replacement with or without aortic arch or descending aortic repair in 30%, and aortic arch with or without descending aortic repair in 1%. Circulatory arrest was used in 78%, with retrograde brain perfusion in 58%.
RESULTS: Hospital mortality was 6%, stroke 4%, renal failure 2%, and respiratory failure 7%. Survival at 30 days and 1, 3, 5, and 7 years was 93%, 85%, 74%, 63%, and 53%, respectively. Aortic reoperation was performed in 7 patients, with freedom from this event at 30 days and 1, 3, 5, and 7 years of 98%, 95%, 93%, 91%, and 89%., respectively
CONCLUSIONS: Aortic dissection after cardiovascular surgery is rare and can be managed with acceptable operative risks and good long-term survival. Need for subsequent aortic reoperation is uncommon.
