REPEATED AORTIC ROOT RECONSTRUCTION AND AORTIC VALVE REPLACEMENT IN 20 YEARS AFTER IMPLANTATION OF AORTIC ALLOGRAFT WITH FIBROUS RING BORING
Surgical treatment of aortic diseases in conditions of «small aortic window» in combination with subvalvular membrane and in the presence of active endocarditis with fibrous ring (FR) abscess is not a simple problem definitely. Using of cryosaved allograft (CSA) is one of solutions of this problem. Applying Manouguian-Seybold-Epting boring allow to sanitize FR area adequately. This kind of operation is rather infrequent and there are isolated descriptions of their applying, but even in case of success, questions of distant period still exist. It's known that operating life of CSA is 8-15 years. As a rule it's nessesary to change it after progress of degeneration and calcinosis. We have experience in applying of method of aortic root reconstruction by Manouguian-Seybold-Epting with implantation of mechanical prosthesis with small diameter, with plasty of ascending aorta with xenopericardiac patch to patient after aortic boring with implantation cryosaved allograft in 20 years after intervention.
