Replacement of dog's aorta by autologous intestinal muscle in the infected retroperitoneum.

The free transplant of intestinal muscle lacking mucosa into an infected vascular bed has been shown to be a suitable replacement for the aorta in dogs. This type of transplant is incorporated into the infected area and shows a high tolerance against progressive infection. Therefore, an autologous transplant may be suitable to ensure continuous blood flow during the healing phase of a deep infection when a synthetic prosthesis is unsuccessful.
