BACKGROUND: Although the aortic root dissection is a common finding in patients with type A acute aortic dissection, it is potentially fatal. Several procedures are available for reconstruction of the aortic root, and the choice depends on the mode of dissection; rupture, coronary ostial disruption or pre-existing cardiovascular diseases (annulo-aortic ectasia, aortic regurgitation: AR). The purpose of this study was to evaluate our surgical strategy of type A acute aortic dissection with proximal involvement.
METHODS: Between 1996 and 2008, 100 patients with type A acute aortic dissection underwent emergency operation at our hospital. Fifteen of them received aortic root intervention simultaneously.
RESULTS: In the initial 3 patients, the dissected aortic root was reinforced by fibrin glue and concomitant coronary bypass grafting was performed. During the follow-up term, residual aortic insufficiency was noted in 2 patients. Aortic root reconstruction was performed in 12 patients. Of these, the most recent 2 young patients underwent a new type of aortic valve sparing procedure, so called "partial remodeling". The postoperative echocardiography demonstrated no AR. There was no operative death in this series, and the long-term results were good.
CONCLUSION: The excellent outcome was demonstrated with the change of surgical strategy. Special care should be taken for precise recognition of the proximal extension of the aortic dissection at operation. Although we recommend consideration of the partial remodeling procedure as an alternative, close observation is mandatory in this particular circumstance.
