uttural pouch tympany involves distension of one or both guttural pouches with air. The condition is seen in horses ranging from birth to 1.5 years of age and is more common in fillies than in colts. A breed predilection has been proposed for Arabian and Paint horses and a genetic basis of disease has been identified in Arabians and German Warmblood breeds, including a gender-specific quantitative trait locus in Warmbloods. The exact cause for guttural pouch tympany is unknown, but the most common explanation is that malformation or dysfunction in the mucosal flap (plica salpingopharyngea) which forms the pharyngeal or***ce to the guttural pouch, creating a one-way valve and trapping air within the affected guttural pouch. In some cases, it is thought that the condition may occur secondary to upper airway respiratory disease and associated inflammation affecting the mucosal flap.

Reduction of uterine prolapse in Straight Egyptian Arabian mare.

Uterine prolapse in mares is a rare but acute postpartum emergency, usually occurring within hours after foaling following expulsion of the placenta. It results from uterine atony, often associated with prolonged or difficult parturition, excessive straining, or traction on the fetal membranes.

Clinically, a large, edematous, dark-red mass protrudes from the v***a, and the mare may rapidly develop shock, hemorrhage, and endotoxemia. The condition is particularly dangerous in mares due to the risk of ovarian artery rupture, which can be fatal.

Immediate treatment includes stabilization of the mare, protection and cleaning of the pr*****ed uterus, prompt and gentle replacement, administration of oxytocin, broad-spectrum antibiotics, and measures to prevent recurrence.
Prognosis is good with early intervention but poor if treatment is delayed.

Endoscopic Laser surgery for treatment of guttural pouch tympany in Arabian filly.

Guttural pouch tympany is a condition in which a young horse's guttural pouch traps excess air, causing a non-painful swelling behind the jaw. It is more common in foals, especially fillies, and can be caused by an inflammation or a congenital defect where the pharyngeal opening acts as a one-way valve, letting air in but not out. Treatment options range from medical management for inflammatory cases to surgical intervention for congenital defects, with a good prognosis for most horses.
