A 4-year-old female spayed English Bulldog presented to Cornell’s soft tissue service for an evaluation of history of respiratory distress. In the month prior to her visit, the patient had two episodes of respiratory distress during car rides, where the patient exhibited cyanosis and increased respiratory effort. In addition, the patient had a history of occasional regurgitation. On presentation, the patient was bright alert and responsive, her vital parameters were within normal limits (RR:16, HR:120, TMP: 101.8), body condition score was 4/9, lung sounds were clear in all fields, respiratory effort was normal, nares conformation was normal, she had a stertor and a stridor, and no murmur or arrhythmia was present. Based on the patient`s signalment, history, sedated upper airway exam, thoracic radiographs, and a fluoroscopic swallow study, she was diagnosed with brachycephalic airway syndrome (BAS), mildly decreased esophageal motility, esophageal diverticulum, and epiglottic retroversion. The patient experienced multiple postoperative complications that resolved with medical and surgical interventions. This seminar will discuss the physical exam findings, diagnosis, and treatment of BAS, and the common surgical complications of BAS surgery.
