RESUMO
Abstract Vascular prostheses, excised because of their functional properties loss, were studied. Using different methods there was established, that this complication is caused by the thrombus formation as a reaction of organism on the prosthesis material. The testing procedure on compatibility was proposed, using atomic-power microscope. Components of a patient immunity may identify the prosthesis material and start the rejection mechanisms in case of negative reaction.

The specificity of the test networks for hernia repair using an atomic force microscopy was studied. The method allows to determine the compatibility of allograft material with the body of the patient, and select the appropriate implant support optimal patient after surgery.
