Dynamic respiratory endoscopy in 67 Thoroughbred racehorses training under normal ridden exercise conditions

Abstract

This technique can be used to diagnose common causes of URT associated with poor performance in horses during normal training. This has substantial implications for future clinical diagnosis and treatment of URT pathology.

Evaluation of The Dynamic (Overground) Endoscopy Procedure in The Diagnosis of Upper Respiratory Tract Diseases Affecting Performance of Racehorses

“…The primary DO-URT cases seen in horses are reported to be DDSP, Laryngeal Collapse (LC), Vocal Cord Collapse (VCC), LLH, ADAF, PI, and Epiglottic abnormalities 1,4,11,12,14,17,18 . DO-URT can also be seen alone or as multiple cases 4,11,12,14,22 . DO-URT cases identified in this study are DPC (16.6%), LLH (10%), DDSP (3.3%), ADAF (10%), DDSP along with ADAF (3.3%) and RDPA (3.3%), respectively.…”

“…Disorders including laryngeal hemiplegia, subepiglottic cyst, and arytenoid chondropathy can be detected by endoscopic examination during resting. However, resting endoscopic examination proves insufficient for the detection of dynamic obstructions including DPC, DDSP, ADAF, and epiglottic retroversion appearing during high performance 13,14,22 . In this case, dynamic endoscopic examination becomes compulsory.…”

“…Because of that automatic water pump with a fixed flushing system would be useful 12,14 . During this study, images could not be collected in one case due to mucus accumulation in front of the camera, so the examination was repeated.…”

“…DO-URT can be diagnosed with the help of DRS and HSTE 5,11,12,14,22,23 . The primary DO-URT cases seen in horses are reported to be DDSP, Laryngeal Collapse (LC), Vocal Cord Collapse (VCC), LLH, ADAF, PI, and Epiglottic abnormalities 1,4,11,12,14,17,18 .…”

The impact of technology on the study of equine upper airway surgery

“…Again, advances in technology provided a solution to this diagnostic problem. Telemetric endoscopes are now available that allow endoscopic examination of the upper airway with horses exercising in the field (Pollock et al 2009). Telemetric endoscopy in exercising horses promises to be a more accurate diagnostic tool in the evaluation of upper airway dysfunction of horses.…”
