Plain-English summary
A 3-year-old Quarter Horse gelding was treated for a serious condition called guttural pouch mycosis, which affected his breathing. During the procedure to place a balloon catheter in his artery, the catheter did not advance as far as expected, and the horse developed breathing problems, did not wake up after surgery, and sadly passed away a few hours later. A postmortem examination revealed that the catheter had been incorrectly positioned due to an unusual artery structure, leading to severe brain and lung damage. This case highlights the importance of careful imaging to avoid complications during such procedures.

Abstract
A 3-year-old Quarter Horse gelding was treated for left guttural pouch mycosis by ligation and balloon catheterization of the left internal carotid artery. Catheter advancement was shorter (10 cm) than the normally reported distance (13-15 cm), but was observed endoscopically during placement as it coursed within the internal carotid artery through the guttural pouch. The horse developed a persistently abnormal respiratory pattern after catheter placement, failed to gain consciousness, developed pulmonary edema, and died 5.5 hours postoperatively. Postmortem examination revealed an aberrant left internal carotid arterial course with location of the embolectomy catheter at the junction of the basilar and caudal cerebellar arteries. Brainstem neuronal necrosis and alveolar and interstitial pulmonary edema were identified on histological examination. Angiography may be used to identify aberrant branching patterns. Failure to identify and occlude aberrant branches may result in fatal epistaxis and Brainstem lesions.
