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. Key words: airways, degeneration, metal alloy, tracheomalacia. Um cao macho, da raga Terrier Brasileiro de seis meses de idade, com dispneia e tosse persistente foi diagnosticado com colapso traqueal intratoracico e pneumonia apos estudo radiografico de torax. Foi instituido tratamento medico e realizada toracotomia para a implantacao de protese traqueal extraluminal de nitinol. O animal nao manifestou dispneia ou pneumonia durante os quatro anos posteriores ao procedimento. A implantacao da protese extraluminal atraves da toracotomia foi eficaz para o tratamento do colapso traqueal intratoracico, sem provocar danos estruturais na regiao toracica. Desta forma, este e primeiro relato da utilizacao bem-sucedida deste tipo de protese, a partir da abordagem intercostal, no tratamento de caes com colapso traqueal intratoracico. Palavras-chave: vias aereas, degeneracao, liga metalica, traqueomalacia.
