Plain-English summary
Researchers developed a new surgical method to place a special type of support, called a polypropylene spiral prosthesis, in the trachea (windpipe) of dogs. They tested this technique on 12 dogs while another 12 dogs underwent a similar surgery without the prosthesis. After the surgery, the dogs that received the prosthesis had mild coughing, and both groups had some swelling at the incision sites. While there were some signs of tissue damage and inflammation, the overall health of the trachea was maintained, and the tissue started to heal within ten days. The authors believe this new technique is beneficial because it helps keep the blood supply to the trachea intact, which is important for healing.
Abstract
A modified surgical technique for application of extraluminal polypropylene spiral prostheses (PSP) to the trachea was developed. A portion of the segmental blood supply to the collapsed segment of trachea was maintained by fenestrating rather than completely dissecting the right lateral pedicle. Polypropylene spiral prostheses were applied to the cervical trachea of 12 dogs (group I) via the modified technique and to 12 dogs (group II) with the identical surgical dissection but without PSP applied. Clinical abnormalities included mild coughing in group I dogs and swelling of the incisions in both groups. Limited necrosis and moderate degeneration and inflammation were observed histologically in both groups. Pathologic changes were worse in the caudal cervical segment of the trachea. Mucosal regeneration was present on day 10 in both groups. Transmural tracheal necrosis was not observed. The modified technique for application of PSP is recommended by the authors because it provides adequate surgical exposure and the blood supply preserved by segmentally dissecting the right lateral pedicle is adequate to maintain tracheal viability.
