Evaluation of the dynamic (overground) endoscopy procedure in the diagnosis of upper respiratory tract diseases affecting performance of racehorses

Bu araştırmada, yarış atlarında performans kaybına neden olan dinamik üst solunum yolu problemlerinin teşhisinde dinamik (mobil) ve rutin endoskopi uygulamalarının etkinlikleri karşılaştırıldı. Performans düşüklüğü ve anormal solunum sesi şikâyetleri ile Türkiye Jokey Kulübü Yarış Atları Hastanesine getirilen 30 yarış atı dinlenme halinde ve koşu sırasında değerlendirildi. Üst solunum yolunun dinamik tıkanıklarının teşhisinde, dinamik ve dinlenme halinde yapılan endoskopi uygulamalarının teşhisteki etkinlikleri karşılaştırıldı. Dinamik endoskopik muayenelerde; 5 atta dinamik farengeal kollaps (DPC), 3 atta 3. ve 4. derece sol larengeal hemipleji (LLH), 3 atta 2. derece ariepiglottik kıvrımların aksiyal deviasyonu (ADAF), 1 atta palatofarengeal kıvrımın rostral deplasmanı (RDPA), 1 atta yumuşak damağın dorsal deplasmanı (DDSP) ve 1. derece ADAFın birlikte bulunduğu gözlendi. Toplam 13 atta dinamik üst solunum yolu problemi belirlendi. Sonuç olarak, yarış atlarında dinamik üst solunum yolu tıkanıklıklarının, dinamik endoskopi ile güvenli ve rutin endoskopi uygulamasından daha iyi bir şekilde teşhis edilebileceği kanaatine varıldı.

Yarış atlarında performansı etkileyen üst solunum yolu hastalıklarının teşhisinde dinamik endoskopi uygulamasının değerlendirilmesi

In this study, efficiencies of dynamic (overground) and resting endoscopic examinations were compared in dynamic upper respiratory tract problems which are a cause of poor performance in race horses. Thirty actively-racing horses which were brought to Turkey Jokey Club Racehorses Hospital with poor performance and abnormal respiratory tract sounds were examined while running and rest. The diagnostic effectiveness of dynamic endoscopy and resting endoscopy procedures were compared for the diagnosis of dynamic obstructions of the upper respiratory tract. Dynamic pharyngeal collapse (DPC) in 5 race horses, third or fourth degree of left laryngeal hemiplegia (LLH) in 3 race horses, second degree of axial deviation of aryepiglottic folds (ADAF) in 3 racehorses, rostral displacement of the palatopharyngeal arch (RDPA) in 1 racehorse, and dorsal displacement of the soft palate (DDSP) along with first degree of ADAF in 1 racehorse were detected in the mobile endoscopic exams. Dynamic upper respiratory tract problem was detected totally in 13 horses. As a result, it was observed that dynamic upper respiratory tract problems could be safely detected by dynamic endoscopy and it was superior than routine endoscopic examination in racehorses.
