A Case of Ascending Aorta Pseudoaneurysm due to a Freestyle-Valve Free-Wall Fistula after a Modified Bentall Procedure with the Button Technique / 日本心臓血管外科学会雑誌

ABSTRACT

We encountered a case of ascending aorta pseudoaneurysm due to a Freestyle-valve free-wall fistula after a modified Bentall procedure with the button technique. A 60-year-old man with Marfan's syndrome who contracted annuloaortic ectasia presented with the onset of Stanford A type acute aortic dissection 3 years ago. The patient underwent aortic root replacement with a Freestyle-valve and ascending and hemi-arch aortic replacement. Thirty-seven months after this operation the patient was re-operated because of pseudo-ascending aorta aneurysm. The cause of the pseudo-aneurysm was a fistula of the Freestyle-valve free-wall and the left coronary artety (LCA) ostial reconstruction component. The fistula was repaired by direct closure with pledgets. The patient was discharged from the hospital 24 days after the operation.
