Clinical presentation and treatment of a bronchocutaneous fistula with intrathoracic abscessation in a yearling

Abstract

This case report describes the clinical presentation, surgical treatment, post-operative management and outcome of a bronchocutaneous fistula with intrathoracic abscessation in a yearling horse. The animal was presented with a history of several months of persistent coughing and a cutaneous fistula located over the right ventral hemithorax. The yearling had purulent discharge similar in character from both nares and draining out of the fistula. A bronchocutaneous fistula with intrathoracic abscessation was diagnosed by endoscopic examination of the cutaneous fistula. The treatment initially consisted of cyanoacrylate applied topically to the affected bronchi under endoscopic guidance, which was not successful. The fistula was successfully sealed with a diode laser used to create local inflammation at the site. One week after the second intervention, the patient's clinical signs resolved and the fistula was completely sealed 10 weeks following intervention. Follow-up at 16 months revealed that the patient was doing well and clinically normal.
