“…Only one patient underwent aggressive surgical treatment, but the prognosis was poor, in contrast to the lymphoma cases. A high proportion of possible lung metastases differed from the previous study, 6 , 8 , 9 , 12 , 14 , 19 which could be due to the difference in population.…”

Objectives This multicentre, retrospective observational study aimed to describe the clinical presentation, diagnostic methods, treatment and outcomes of cats with tracheal masses. Methods Eighteen cats from five academic or secondary/tertiary animal hospitals were included. Results The median age at diagnosis was 10.7 years (mean 9.5; range 1–17). There were nine castrated males, seven spayed females, one intact male and one intact female. Fourteen (78%) were domestic shorthairs, one (6%) was an Abyssinian, one (6%) was an American Shorthair, one (6%) was a Bengal and one (6%) was a Scottish Fold. The most common presenting complaints included chronic respiratory distress or dyspnoea (n = 14), followed by wheezing/gagging (n = 12), coughing (n = 5) and voice changes (n = 5). There was cervical tracheal involvement in 16/18, and two showed involvement of the intrathoracic trachea. The following methods were used for diagnosis: ultrasound-guided fine-needle biopsy (UG-FNB) and cytology (n = 8), bronchoscopic forceps biopsy and histopathology (n = 5), surgical resection and histopathology (n = 3), forceps biopsy via an endotracheal tube (n = 1) and histology of tissue sputtered from a cough (n = 1). Lymphoma was most often diagnosed (n = 15), followed by adenocarcinoma (n = 2) and squamous cell carcinoma (n = 1). Most lymphoma cases received chemotherapy with or without radiation according to various protocols, and partial (n = 5) or complete responses (n = 8) were noted. Kaplan–Meier survival data for cats with lymphoma revealed a median survival time of 214 days (95% confidence interval >149 days), which was significantly longer than that of other types of tumours (21 days). Conclusions and relevance Lymphoma was the most prevalent diagnosis, and showed a good response to chemotherapy with or without radiation therapy. Various diagnostic procedures were performed, and UG-FNB and cytology are good diagnostic procedures for cervical tracheal lesions. Owing to the variety of treatment protocols at different centres, it was impossible to compare outcomes.

“…[1][2][3] Some of these surgeries, particularly in the case of tracheostomy, are associated with a high rate of complications. [4][5][6][7][8][9][10][11] Tracheal surgery techniques have been developed primarily for dogs. These techniques were then translated and adapted to cats under the assumption that the tracheal anatomy is comparable between the two species.…”

Objectives The aim of this study was to measure the tracheal dimensions of normocephalic cats using CT. Methods CT images of 15 client-owned normocephalic cats were retrospectively evaluated to measure the length of the feline trachea. Transverse and vertical inner diameters were measured in five different tracheal regions, and the cross-sectional area of the tracheal lumen was calculated for each point of measurement. Descriptive statistics were applied using a two-tailed t-test. Results The mean ± SD length of the trachea was 125.13 ± 14.41 mm. Male cats had significantly larger tracheas than female cats. The transverse diameter first increased by 0.94 mm between the most cranial point of measurement and the middle of the trachea. It then decreased by 1.38 mm between the middle of the trachea and the most caudal point of measurement. The vertical diameter decreased by 1.16 mm between the first point of measurement and the penultimate point, and then increased by 0.06 mm between the penultimate point of measurement and the end of the trachea. The two different diameters resulted in an elliptical trachea shape. Conclusions and relevance The feline trachea was circular only at its cranial and caudal ends, and elliptical with a dorsoventral flattening along the rest of its length. Vertical and transverse diameters varied along the entire length. Tracheal shape differences should be considered when performing permanent tracheostomy, tracheal anastomosis or stenting in cats.

Primary tracheal malignant neoplasms are rare in dogs and cats. Mostly seen in middle-aged to older cats. Clinical findings associated with airway obstruction are observed. Shortness of breath, wheezing, cough, and cyanosis are among the clinical findings. Radiography, endoscopy, computed tomography (CT), magnetic resonance imaging (MRI) can be used for diagnosis. The material of this report is a 12-year-old, 6.3 kg, castrated male cat brought to Istanbul University-Cerrahpasa, Faculty of Veterinary Medicine, Department of Surgery due to with symptoms of cough and difficulty breathing. In the anamnesis, it was learned that the patient's tracheal mass was removed by operation 8 months ago in another clinic. As a result of the examinations and tests performed, it was observed that the tracheal mass recurred. The mass was removed by tracheal ring resection. Histopathological result has been reported as adenocarcinoma.
