[Giant Anastomotic Aneurysm Associated with Albumin/Glutaraldehyde Sealant as a Late Complication after Acute Aortic Dissection Surgery:Report of a Case].

A 74-year-old woman was taken to our hospital with a chief complaint of chest and back pain. She was diagnosed with Stanford type A acute aortic dissection and underwent ascending aortic replacement. Fifteen months after surgery, a giant anastomotic aneurysm was found at the proximal and distal anastomoses on chest computed tomography (CT), and reoperation was indicated. Following sternal re-entry, anastomotic dehiscence was found where BioGlue, albumin/glutaraldehyde sealant, had been applied during the previous surgery, and caused aneurysm. Severe postoperative adhesion precluded extensive surgery, and redo replacement of the ascending aorta was carried out. Histopathological examination revealed extensive necrosis of smooth muscle cells in the aortic wall at the anastomotic site and a marked inflammatory cell infiltration around the aortic wall and the artificial graft, and association of BioGlue use was suggested. The use of appropriate tissue adhesives to reinforce the dissected aortic wall is important, as well as careful long-term follow-up.
