OBJECTIVE: To investigate the effectiveness of surgical approaches, outcomes and prognosis of aortic root pathology due to Stanford A aortic dissection.
METHODS: Retrospective analysis the clinical data of 161 patients (122 male and 39 female, mean age of (44 ± 21) years) underwent surgical treatment for Stanford A aortic dissection between January 2001 and June 2011. There were 146 patients of acute aortic dissection and 15 patients of chronic aortic dissection. All the patients had aortic root pathologies that included commissural prolapsed in 140 cases, more than moderate aortic insufficiency in 75 cases, aortic sinus intima rupture in 15 cases, right and/or left coronary artery tearing in 8 cases, right and/or left coronary artery dissection in 16 cases, aortic root aneurysm in 31 cases.
RESULTS: Aortic root replacement (Bentall procedures) were used in 72 cases, aortic root remodeling (including aortic valve replacement) in 80 cases, aortic root reimplantation (David procedure) in 9 cases. The cardiopulmonary bypass time was shorter in aortic root remodeling group ((193 ± 42) minutes) than the other two groups ((210 ± 61) minutes, (197 ± 34) minutes, F = 3.22, P = 0.04). The in-hospital mortality was 8.1% (13 cases), 5 cases (6.9%) in aortic root replacement group, 7 cases (8.8%) in aortic root remodeling group, 1 case in aortic root reimplantation. The cause of death included respiratory failure (4 cases), permanent neurological deficits (3 cases), multiple organ failure (4 cases), acute renal failure (2 cases). The survivors were followed up for 6 months to 6 years. There was no patient required reoperation for aortic root pathologies. There was no statistically significant difference between aortic root remodeling group and reimplantation group (P > 0.05).
CONCLUSIONS: The surgical treatment for aortic root pathology due to Stanford A aortic dissection is challenging. Appropriate procedures according to the specialty of aortic root pathology can be performed with favorable functional results.
