Omental pedicle graft in the management of infected ascending aortic prostheses.

Two patients had mediastinal infections with chronic draining sinus tracts that involved a vascular prosthesis in the ascending aorta. In 1 patient, a false mycotic aneurysm developed and in the other, a beginning rupture of the proximal suture line. In both patients, the infection was cured by replacing the infected aortic prosthesis combined with wrapping the new prosthesis with a pedicled omental graft. An omental graft was used to protect the vascular prosthesis and minimize the risk of recurrent infection.
