Abstract
Fibrin glue was used to preseal high porosity knitted Dacron grafts in repair of thoracic aneurysms in sixteen patients under extracorporeal Circulation. Mean duration of extracorporeal circulation was 171 minutes. There were no early and late complications related with this procedure, except one patient, who had bleeding through the presealed graft during surqery. Hepatic dysfunction was found in two of ten patients with use of fibrin glue and in one of ten without its use.
