By means of experimental material from 339 animals it was shown that microsurgical technique provides primary recovery of the wounds of the hollow organs, their anastomoses and blood vessels: demineralized bone is found to be a suitable material easily adapting in implantation. The use of microsurgical methods and technique and demineralized osseus matrix for nonosseous plastics is a perspective direction in improvement of the results of reconstructive and restorative operations on hollow organ and blood vessels.
