[Experimental-morphological reasons for using dura mater for plastic surgery of defects of the anterior abdominal wall].

A possibility to use preserved dura mater (in 2% formalin) for substituting various abdominal wall layers under both sterile and infectious conditions has been studied experimentally in 126 dogs. Morphological investigation has been performed at various postoperative time (1 day--2 years). It has been stated that the dura mater implantation produces minimal aseptic inflammatory reaction in the abdominal wall tissues. The transplant is gradually disorganized and resolved and simultaneously substituted with the connective tissue. There are no commissurae between the transplant and the abdominal organs. The dura mater is resistive to infections. Application of the dura mater for surgery of hernia of the abdominal wall is substantiated.
