title: Periprosthetic cyst formation: an unusual complication of polytetrafluorethylene prosthesis implantation.
abstract: Two cases of periprosthetic cyst formation after polytetrafluorethylene (PTFE) graft implantation are reported. This complication may have resulted from imperfect incorporation of the graft material by the surrounding tissues. The cause of such defective incorporation, and hence the means of prevention, remains unknown.
