[Changes in the form of perigraft reaction]

Perigraft-reaction is characterized by a late fluid accumulation around a graft. As a rule bacterial contamination is missed. The fluid has the same characteristics as blood serum. An aggressive surgical approach is necessary. The cyst wall must be excized and the prosthesis has to be replaced by a different synthetic material. In these cases a healing can be expected in more than 90%. By using the same material after resection of the cyst wall is followed by a recurrence rate of 79%.
