Tracheal collapse is often diagnosed in small-breed dogs through use of conventional radiography or fluoroscopy, by which the dorsoventral orientation of the collapse can be seen. In the dog of this report, an unusual lateral form of tracheal collapse was diagnosed by means of bronchoscopy after multiple radiographic procedures had failed to define a cause for cough and dyspnea. Surgical reinforcement of the abnormal region of the trachea resulted in resolution of clinical signs and in reduction in dynamic airway collapse, which was documented on follow-up bronchoscopy.
气管塌陷通常通过传统的X线摄影或荧光镜检查在小型犬中得以诊断，借此可观察到塌陷的背腹方向。在本报告中的这只犬，经过多次影像学检查未能明确咳嗽和呼吸困难的病因后，通过支气管镜检查诊断出一种不常见的气管塌陷侧位形式。对气管异常区域进行手术加固后，临床症状得到缓解，动态气道塌陷减轻，后续支气管镜检查证实了这一点。
