Plain-English summary
In this case, a horse with a fungal infection in the guttural pouch (a space near the throat) had an unusual branch of the internal carotid artery found during a special imaging test called angiography. To treat the problem, a detachable latex balloon was used to block the artery, and a second balloon was added to prevent bleeding from the abnormal branch. After the procedure, the horse recovered well and was able to return to its normal activities. This situation suggests that unusual blood vessel structures in the internal carotid artery might happen more often than we think, and recognizing them during surgery could help prevent serious complications. Overall, the treatment was successful.
Abstract
An aberrant branch of the internal carotid artery was detected by angiography in a horse with guttural pouch (auditory tube diverticulum) mycosis after the distal portion of the artery had been occluded by use of a detachable latex balloon. A second balloon was placed to eliminate retrograde hemorrhage from the aberrant branch. The horse recovered and returned to its previous activity. Vascular anomalies of the internal carotid artery my be more common than expected, and have resulted in fatal complications during and after surgical treatment in guttural pouch mycosis. Intraoperative identification of vascular anomalies by use of angiography may avoid these fatal complications.
