    Abstract:
    This study analyses the clinical course of five patients who developed acute ascending aortic dissection 45.8 months (17-87 months) after aortic valve replacement (AVR) and underwent reoperation in our Department. All except one had aortic insufficiency with mild dilatation of the ascending aorta. No evidence of aortic wall degeneration was present at the time of AVR. Prostheses implanted were: Hancock 2, St. Jude 2, Bjork-Shiley 1. Associated procedures (coartectomy, coronary artery by-pass) were carried out in two patients. The dilated aorta was managed at the first operation by longitudinal resection in 3 of them. Emergent aortic dissection repair was performed: in 3 cases with composite graft according to the Bentall procedure, in one case with non valved dacron conduit and in the last case with teflon patch. Histological examination of the dissected aortic wall showed elastic fiber degeneration like cystic medial necrosis. Three patients survived surgical repair and are doing well at 22.4 months of mean post-operative follow-up. Surgical strategy of this complication is discussed; particular emphasis is given to the method of treatment of ascending aorta dilatation during AVR.
