Background: During surgical treatment for acute type A aortic dissection, gelatin-resorcin-formalin glue is generally applied and its efficacy has been reported. However, some late complications that are potentially associated with this glue have also been reported. In the present study, we reviewed our experiences of treatment for acute type A aortic dissection and late complications that occurred in the anastomotic site, which needed a reoperation.

Methods: From October 1994 to August 2005, 68 patients underwent emergency surgery for acute type A aortic dissection. Gelatin-resorcin-formalin glue was applied to 56 (82.4%) of these patients at one or both of the distal and proximal anastomosis sites.

Results: Eight (11.8%) patients died in hospital within 30 days after the operation, among which two patients already had cerebral complications prior to the surgery. There were five late deaths from causes unrelated to cardiac events. Five patients developed an aortic pseudoaneurysm at the anastomotic site and underwent a late reoperation. All of these patients had been treated with gelatin-resorcin-formalin glue during the previous operation. Histologic examination of the resected aortic wall after the reoperation revealed tissue necrosis, severe local inflammation, and organization of old thrombi at the site of the glue application.

Conclusions: Late complications after the use of gelatin-resorcin-formalin glue may occur with a certain amount of risk, suggesting its toxicity for aortic tissue. Therefore, proper use of this glue and close follow-up of the patients are strictly required.
