Surgical treatment of extensive chondroid formation in the guttural pouch of a Warmblood horse

Abstract

A Warmblood horse presented with a purulent nasal discharge that had failed to respond to antibiotic therapy. Radiography and endoscopy confirmed a large number of chondroid masses (over 200) in the left guttural pouch. Despite the large number of chondroids present, there was no external swelling evident. The masses were surgically removed via a hyovertebrotomy approach that provided excellent exposure, and no postoperative complications were encountered. Long term follow-up (3 years) confirmed a successful outcome.

Functional Electrical Stimulation of Intrinsic Laryngeal Muscles under Varying Loads in Exercising Horses

“…This procedure can be performed without sedation in the conscious animal [28]–[32]. This adaptation depends on the normal function of a highly adapted upper airway: the long axis of the larynx is rotated though 90° to optimize airflow [33] which can reach up to 80 L/s when racing at speeds of up to 44miles/hour [34]–[38]. By comparison, peak inspiratory flow in exercising humans is 2 L/s [39].…”

Endoscopic assisted electro-cauterization to treat an acquired pharyngeal ostium stenosis in a horse: a case report

“…However, when conservative treatment does not result in desirable outcomes, it is necessary to carry out surgical treatment, which can be performed in different ways: via a hyovertebrotomy (Schaaf et al, 2006), with the Whitehouse technique and modified Whitehouse technique (Gehlen and Ohnesorge, 2005;Perkins et al, 2006), with fistulation through the Viborg's triangle, and with the fenestration of the mesial guttural pouch septum (Perkins et al, 2006). However, these surgical techniques could result in complications, such as iatrogenic lesions of cranial nerves and subsequent neurological dysfunction, including dysphagia and/or cranial neuropathies (Perkins et al, 2006;Fogle et al, 2007).…”

“…The incidence of guttural pouch diseases in the horse, such as empyema, tympany and mycosis, is rather low (Carmalt, 2002;Schaaf et al, 2006), and reports in the literature are constituted by several articles with a small number of cases (Freeman, 2006;Perkins et al, 2006;Schambourg et al, 2006) rather than retrospective studies with large numbers of cases (Judy et al, 1999). Inflammatory processes of the guttural pouch can result in empyema, which is sometimes complicated by chondroids and exudate conglomerates.…”
