Cohort study examining long‐term respiratory health, career duration and racing performance in racehorses that undergo left‐sided prosthetic laryngoplasty and ventriculocordectomy surgery for treatment of left‐sided laryngeal hemiplegia

Abstract

Owners and trainers should be advised that racehorses with LLH that undergo PLVC surgery are at an increased risk of respiratory conditions (IAD and severe EIPH), which is likely to shorten their racing career compared to racehorses with normal laryngeal function. Racing performance in terms of race starts was significantly less in racehorses that had undergone PLVC surgery; however, the number of starts for which stakes money was earned was similar to those racehorses that were unexposed.

Inflammatory Airway Disease of Horses—Revised Consensus Statement

“…It is important to note that IAD and upper airway disorders are both relatively common and concomitant occurrence in the same horse is therefore not rare. There is also some circumstantial evidence that IAD may be more prevalent in horses with pharyngeal dysfunction and laryngeal surgery 110, 111. Conversely, severity of upper and lower airway inflammation and endoscopic scores were found to be independent 11…”
