Dumon silicone stents can improve respiratory function in dogs with grade IV tracheal collapse: 12 cases (2019-2023).

Objective: To evaluate the efficacy, complications, and outcome of Dumon silicone stent placement for dogs with grade IV tracheal collapse.

Animals: 12 client-owned dogs.

Clinical Presentation: Each dog was diagnosed with grade IV TC unresponsive to medical therapy and had severe obstructive respiratory failure.

Nasopharyngeal sialoceles in 11 brachycephalic dogs.

Objective: To report clinical features, diagnosis, surgical treatment, and outcomes of brachycephalic dogs with nasopharyngeal sialoceles (NPS).

Study Design: Retrospective case series.

Animals: Eleven brachycephalic dogs with NPS.

Treatment of acquired nasopharyngeal stenosis using a removable silicone stent.

The aim of this prospective study was to characterise patient characteristics and the histories of cats with acquired nasopharyngeal stenosis (ANS), and to describe the use of a removable silicone stent for treatment. ANS was diagnosed in 15 cats with clinical signs present for a median of 4 months. Clinical signs included stertor and inspiratory difficulty, nasal discharge, sneezing, dysphagia, regurgitation, vomiting and anorexia.

Bronchial abnormalities found in a consecutive series of 40 brachycephalic dogs.

Objective: To detect abnormalities of the lower respiratory tract (trachea, principal bronchi, and lobar bronchi) in brachycephalic dogs by use of endoscopy, evaluate the correlation between laryngeal collapse and bronchial abnormalities, and determine whether dogs with bronchial abnormalities have a less favorable postsurgical long-term outcome following correction of brachycephalic syndrome.

Design: Prospective case series study.

Animals: 40 client-owned brachycephalic dogs with stertorous breathing and clinical signs of respiratory distress.

Differential cell counts in canine cytocentrifuged bronchoalveolar lavage fluid: a study on reliable enumeration of each cell type.

Background: Bronchoalveolar lavage (BAL) allows cell recovery from the lower respiratory tract; differential cell counts of BAL fluid gives important information in the assessment of various bronchial and pulmonary diseases. To the best of our knowledge no study has investigated the relation between the number of cells counted and the reproducibility of BAL fluid differential cell counts.

Objective: The purpose of this study was to investigate using statistical methods how many cells should be counted in cytocentrifuged BAL fluid preparations in order to obtain a reliable enumeration of each cell type.

Squash-preparation cytology from nasopharyngeal masses in the cat: cytological results and histological correlations in 30 cases.

Upper airway obstruction in cats can be a life-threatening condition. Early recognition of clinical signs and an appropriate diagnostic approach increases the possibility of appropriate therapeutic choices. The purpose of this study was to assess the efficacy and diagnostic value of squash-preparation cytology in providing an accurate diagnosis of masses growing in the nasopharynx of cats.
