Abstract: We report a case of surgical treatment for pseudoaneurysm 19 years after aortic root replacement. The patient was a 57-year-old female who had undergone aortic root replacement (Piehler procedure) in another hospital due to acute Stanford A type aortic dissection in 1988, and was then followed up at another hospital. However, a low density area around the artificial graft was pointed out on computed tomography (CT) in 2001, which increased to 60mm in size by November, 2006. She was then referred to our hospital for a redo operation. Pseudoaneurysm of the anastomosis and mitral regurgitation (MR) was diagnosed by the examination of the CT, angiography, etc., and we performed ascending aorta and aortic arch replacement, and mitral valve replacement (MVR) in April, 2007. A slight hemorrhage were found at the anastomosis of the artificial graft-artificial graft. Deterioration of the artificial graft or deterioration of the suture was suspected as the cause of the slight hemorrhage from the anastomosis a long period after the operation. In this case, loosening of the suture string was revealed, so the latter was more strongly suspected.
