Complete upper airway obstruction and syncope caused by a subepiglottic cyst in a horse.

The research paper discusses a rare case where a horse suffered from full upper airway obstruction and fainting caused by a subepiglottic cyst.

Introduction

• The study is focused on a particular case where a horse experienced full upper airway block and fainted due to a subepiglottic cyst. This is different from the typical instances of horses developing subepiglottic cysts that lead to partial upper airway obstruction.

Subepiglottic Cysts in Horses

• Subepiglottic cysts in horses have been found in both adults and foals. These cysts are often linked with partial pharyngeal airway blockages.
• Prior research (Raker 1976, Koch and Tate 1978, Stick and Boles 1980, Tulleners 1991) has documented the correlation between subepiglottic cysts and upper airway obstruction in horses.

Unusual Presentation

• This research outlines an unusual circumstance where the subepiglottic cyst induced a complete blockage in the horse’s upper airway. This is contrary to the usual partial obstructions related to these cysts.
• Along with the complete airway obstruction, the horse also experienced syncope, a term used to describe sudden and temporary loss of consciousness, typically caused by insufficient blood flow to the brain – in this instance, brought on by the severe airway obstruction.

Significance

• The study is essential as it draws attention to the potential severity of subepiglottic cysts in horses, and the extreme complications they can induce, such as complete airway blockage and syncope.
• By emphasizing this uncommon presentation, the study promotes awareness among veterinarians and horse owners, prompting them to consider the possibility of such cases while dealing with symptoms of airway obstruction in horses.
