Abstract
Background: Acute aortic dissection frequently involves ascending aorta and aortic root. Depending to aortic valve and root pathology, the proximal aorta can be replaced by two standard surgical methods: Aortic root reconstruction or supracoronary replacement of ascending aorta. We tried to compare these two surgical methods with surgical mortality and long term outcomes.
Methods: Between January 2007 and June 2017, 100 patients who had acute ascending aortic dissection underwent operations. Patients were divided into two groups according to the surgical procedure. Supracoronary replacement of aorta was applied in 68 patients (Group 1). The other 32 patients with severely dilated or destructed aortic root underwent root reconstruction procedure (Group 2).
Results: Hospital mortality was 19.1% in group 1 and 25% in group 2 (P=0.3936). Long term survival was 73.5% vs 71.8%, 67.7% vs 65.6, 60.3% vs 59.4%, 54.4% vs 53.1%, 48.5% vs 43.8% in 2, 4, 6, 8, 10 years after surgery respectively. Rate of redo surgery was 4 patients in group 1, 2.72 % (3 for distal spread of aortic dissection and 1 for prosthesis infection) and 1 patient in group 2, 0.32 % for distal spread of aortic dissection. There was
no redo operation for aortic valve or root problem. The type of surgical procedure was not found to be an independent predictor of hospital mortality, long term survival and redo operations.
Conclusions: Supracoronary replacement of aorta and aortic root reconstruction procedure are comparable standard operative methods for acute ascending aortic dissection with favorable long term results.
