[Surgical treatment of type A aortic dissection combined with aortic root lesions].
|
| Abstract |
From January 1980 to December 1992, 36 patients with type A aortic dissection were operated on at the St. Marianna University Hospital. Hospital mortality and 10-year survival rate in 26 patients (Group I and II) undergoing replacement of the ascending aorta with or without hemi-arch resection (including one case of aortic wrapping for the closing dissection) were 19.2% and 88.0%, respectively. Among the patients having aortic root destructions due to acute aortic dissection or preexisting annuloaortic ectasia (Group III), 8 patients underwent aortic root reconstruction with a valved conduit and 2 patients supra-coronary aortic resection and graft replacement with concomitant coronary artery bypass grafting with 20.0% of hospital mortality and 55.6% of 10-year cumulative survival rate. Modified Bentall operation using Carrel patch method seems to be preferable to avoid postoperative complications for the case with intimal tear extending to the aortic sinuses, ruptured outer layer of the aortic root or preexisting AAE. If the disrupted coronary artery is concerned, coronary artery bypass grafting is mandatory. In the case of replacement of the ascending aorta for the dissection extending to the aortic sinuses, complete obliteration of the proximal false lumen must be required to avoid uncontrollable bleeding and compromised coronary blood flow.
