[Preservation of aortic root with severe destruction in Stanford type A acute aortic dissection].

From November 1999 to December 2008, 197 patients with Stanford type A acute aortic dissection underwent the surgical treatment on an emergency basis. In 19 cases, we preserved the severely destroyed aortic root using gelatin-resorcin-formalin (GRF) glue avoiding aortic root replacement. We examined the indication and limitation of repair of the destroyed aortic root. The 19 patients were classified into 3 groups (A, B and C). Group A consisted of 7 patients who had no aortic regurgitation (AR). Group B consisted of 6 patients who had moderate to severe AR. Group C consisted of 6 patients who had coronary involvement. We preserved the broken aortic root in group A and group B. But it seemed to be rather difficult to repair the destroyed aortic root in some cases of group C.
