Treatment of guttural pouch tympany in foals with transnasal Foley catheter placement

This case series describes a technique to treat guttural pouch tympany that may be useful to equine practitioners. The objective of this work is to describe the treatment technique, outcome, possible complications and benefits. Data from a retrospective case series obtained by records review and follow‐up with owners and referring veterinarians were used. Foley catheters were placed into the guttural pouch using endoscopic guidance via the nasal passage, the balloon inflated and the catheter sutured to the external nares under tension. Foals were treated successfully with this method and complications were minor. This treatment method is a viable, low‐cost option for guttural pouch tympany in foals.
