Stent placed by endoscopy for the treatment of tracheal obstruction caused by a tumor in a domestic cat / Stent placed by endoscopy for the treatment of tracheal obstruction caused by a tumor in a domestic cat

Background: Tracheal tumors are rare and may cause obstruction of the trachea. The neoplasms most commonly diagnosed in cats are lymphosarcoma, squamous cell carcinomas and adenocarcinomas. Surgical resection may provide a clinical cure for small, benign and localized tumors. For malignant neoplasia, surgery is usually palliative. Tracheal segment excision is an invasive procedure, particularly when the intrathoracic trachea is involved, and this increases the risk of stenosis, surgical suture dehiscence, necrosis and pneumothorax. Intraluminal tracheal stents have been used in dogs with tracheobronchomalacia, presenting a feasible alternative to surgery for the treatment of tracheal lumen obstruction.Case: A 11-year-old male mixed-breed cat was referred to the Veterinary Hospital of the Federal University of Rio Grande do Sul (HCV-UFRGS) with a history of appetite loss, wasting and progressive inspiratory dyspnea, for the last 30 days. The cat presenting with oral breathing. Radiography of the lateral thorax shown a radiopaque area, 1cm in diameter, superimposed in the tracheal region, close to the carina cartilage, at the fourth intercostal space. A tracheoscopy confi rmed the diagnosis of tracheal neoplasia, which was identifi ed as an adenocarcinoma by biopsy and histopathology. Given that surgical resection may result in signifi cant morbidity and consequent mortality, the

Adesivo de cianoacrilato no tratamento de descemetocele em um canino: relato de caso

Introdução: Adesivos de cianoacrilato são utilizados em oftalmologia em lesões corneanas como microperfurações, afinamentos importantes, úlceras superficiais refratárias e descemetoceles. A aplicação desses adesivos visa manter a integridade da córnea, visto que uma úlcera pode evoluir desfavoravelmente para a perfuração ocular, predispondo a complicações como endoftalmites, catarata, glaucoma, e até mesmo a perda da visão. Apesar de apresentar excelentes resultados, o uso do adesivo de cianoacrilato em casos clínicos ainda é limitado. Este trabalho teve como objetivo relatar a experiência obtida com o uso do adesivo de cianoacrilato no tratamento de descemetocele em um canino.Caso: Um cão da raça Shih-Tzu, com cinco anos de idade, macho, foi encaminhado ao Serviço de Oftalmologia Veterinária da Universidade Federal do Rio Grande do Sul, apresentando desconforto ocular. Ao exame oftálmico observou-se fotofobia, blefaroespasmo, hipópio, secreção ocular e descemetocele do bulbo do olho esquerdo com cerca de 3 mm de diâmetro. O olho contralateral apresentava-se sem alterações. O animal se apresentava em bom estado geral e com hemograma e exames bioquímicos normais, e foi encaminhado para tratamento com uso de N-butyl-2-cianoacrilato (Histoacryl®, B Braun) e recobrimento com a terceira pálpebra. Os procedimentos operatórios foram realizados sob anestesia geral inalatória com auxíli
