Background: Tracheal collapse in horses is reportedly uncommon; however, American Miniature Horses are more commonly affected. To the authors’ knowledge, there is no description of the tracheal luminal diameter of normal sample of American Miniature Horses, making early detection of tracheal luminal narrowing difficult.Objectives: To 1) describe radiographic tracheal luminal diameter in clinically normal American Miniature Horses, 2) report the prevalence of tracheal collapse in a population of subclinical American Miniature Horses, and 3) use tracheal video fluoroscopy to quantify variation in tracheal luminal diameter throughout the respiratory cycle in American Miniature Horses with no history or clinical signs of respiratory disease.

背景：据文献报道，马的气管塌陷并不多见，但美国矮种马（American Miniature Horses）的发病率相对更高。据本文作者所知，目前尚无针对健康美国矮种马样本的气管管腔直径相关描述，这给气管管腔狭窄的早期检测带来了困难。研究目的：1） 描述临床健康美国矮种马的放射学气管管腔直径特征；2） 报告亚临床美国矮种马群体中气管塌陷的患病率；3） 采用气管视频透视检查（tracheal video fluoroscopy），量化无呼吸系统疾病病史及临床症状的美国矮种马在整个呼吸周期内的气管管腔直径变化情况。
