Tracheal resection and anastomosis combined with the application of collagen-PVP in a dog with traumatic tracheal rupture: A new approach to improve tracheal healing.

The treatment for tracheal injuries is tracheal resection and anastomosis (TRA). Although there are few reports in the veterinary literature, TRA can be complicated and lead to the development of tracheal stenosis, fistulas, or malacias. In human medicine and experimentally in dogs, to avoid such sequelae, TRA combined with wound healing modulators (WHM), such as polyvinyl-pyrrolidone collagen (collagen-PVP), can be applied. In this report, we present a case of tracheal rupture in a dog caused by a bite and treated with TRA combined with collagen-PVP. We observed that from the first week after surgery, the animal presented good clinical evolution without complications, and at 6 months, tracheoscopy revealed normal scarring of the anastomosis; therefore, we believe further studies are worthwhile for its potential clinical application.
