Plain-English summary
A 24-year-old Morgan gelding was brought in for severe nosebleeds (epistaxis) coming from the right side. After imaging tests, the vet found a pseudoaneurysm (an abnormal bulge) in the palatine artery that was causing the bleeding. They successfully treated it with a procedure called transarterial coil embolization, which blocked the artery to stop the bleeding. After the surgery, the horse had some mild nasal discharge and a cough, but there were no more nosebleeds, and he was discharged after four days. Unfortunately, he later developed colic due to another issue and was euthanized two months later.

Abstract
OBJECTIVE: To describe successful transarterial coil embolization of a palatine artery pseudoaneurysm that extended into the caudal maxillary sinus of a gelding. STUDY DESIGN: Clinical report. ANIMAL: A 24-year-old Morgan gelding with right-sided epistaxis. METHODS: The right maxillary sinus was imaged by radiography, computed tomography, and sinoscopy. Angiography was performed to locate the source of bleeding, and transarterial coil embolization of a right palatine artery pseudoaneurysm was performed. RESULTS: There was some mucoid nasal discharge and an intermittent cough postoperatively. No epistaxis was seen after embolization. There was moderate swelling of the surgical incision over the mid-cervical common carotid artery. The horse was discharged from the hospital 4 days after surgery, and had been doing well, with no signs of bleeding, for 2 months postoperatively. The horse had acute colic secondary to a strangulating lipoma at 2 months and was euthanatized after exploratory celiotomy. Placement of embolization coils in the right palatine artery was confirmed by CT and necropsy. CONCLUSIONS: Severe epistaxis in the horse may be caused by a ruptured major palatine artery pseudoaneurysm. Occlusion of this vessel can be successfully accomplished by transarterial coil embolization.
