A 45-year-old man presented with cough and dyspnea. He had undergone reconstruction
of the ascending aorta for acute aortic dissection (DeBakey type I) 5 months
previously, at which time we used the gelatin-resorcin-formalin glue (GRF
glue) for reconstruction of the wall layer. Preoperative transesophageal
echocardiography and aortography revealed aortic regurgitation due to redissenction
of the aortic root. Intraoperatively, dehiscence was noted between the
right coronary sinus including the coronary ostia and the non-coronary
sinus. These intraoperative findings suggested that the pathology leading
to the redissection was related to the previous use of GRF glue. The redissected
segment appeared to be necrotic on macroscopic examination intraoperatively,
however histological examination revealed only degenerative changes, and
there was no evidence of the glue. He was treated by the modified Bentall
method and had a good postoperative course after discharge. In this case,
it is also conceivable that tissue necrosis resulted from the use of too
much formalin.
