[Aortic root replacement with a freestyle stentless valve for prosthetic valve detachment caused by aortitis syndrome; report of a case].

: A surgical case of a 65-year-old man with aortitis syndrome is presented. The patient had undergone aortic valve replacement for aortic valve regurgitation with a mechanical prosthesis, followed by a re-do operation (valve fixation) for prosthetic valve detachment 6 months after the 1st operation. Three months after the 2nd operation, perivalvular leakage due to valve detachment was detected again. Aorticroot replacement with a Freestyle stentless valve( full root technique) was performed. Prednisolone was given postoperatively, and no valve detachment nor pseudoaneurysm formation has been noted for 8 years.
