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.</p> </sec> <sec id="vsu12174-sec-0006" sec-type="section"> <title>Conclusions</title> <p>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.</p> </sec> </abstract>
