[Morphological evaluation of structural changes in the tracheal wall at the site of braided and monofilament sutures in experimental animals].

To select the most adequate suture material for tracheal surgery the authors studied tissue specimens of tracheal anastomoses from 18 guinea pigs. Scar replacement of the cartilage plate occurred more frequently in monofilament prolene suture compared to braided vicryl. Tracheal wall structural changes were related to rigidity of the suture material. The rigidity was higher in monofilament material and increased with the filament thickness.
