Description
Summary:A six-month-old male Brazilian Terrier with persistent cough and dyspnea was diagnosed with intrathoracic tracheal collapse and pneumonia after chest radiographics. The medical treatment was performed, and an extraluminal nitinol prosthesis was placed through thoracic access. The dog did not presented recurrence of dyspnea or pneumonia for four years after the surgical procedure. Placement of the extraluminal prosthesis with the thoracic approach effectively stabilized intrathoracic tracheal collapse without causing any structural damage in the thoracic region. Therefore, this is the first report of a successful use of this prosthesis with an intercostal approach in dogs for intrathoracic trachea collapse. RESUMO: Um cão macho, da raça Terrier Brasileiro de seis meses de idade, com dispnéia e tosse persistente foi diagnosticado com colapso traqueal intratorácico e pneumonia após estudo radiográfico de tórax. Foi instituído tratamento médico e realizada toracotomia para a implantação de prótese traqueal extraluminal de nitinol. O animal não manifestou dispneia ou pneumonia durante os quatro anos posteriores ao procedimento. A implantação da prótese extraluminal através da toracotomia foi eficaz para o tratamento do colapso traqueal intratorácico, sem provocar danos estruturais na região torácica. Desta forma, este é primeiro relato da utilização bem-sucedida deste tipo de prótese, a partir da abordagem intercostal, no tratamento de cães com colapso traqueal intratorácico.
