Physical examination upon arrival was unremarkable. Blood work revealed leukocytosis without anemia. Thoracic radiographs from the referring veterinarian demonstrated the presence of an osseous esophageal foreign body at the level of the heart base. Subsequently, esophagoscopy was performed under general anesthesia. A triangular\u2010shaped, osseous esophageal foreign body was visualized at the level of the heart base and successfully removed. Following its removal, a deep, nonbleeding, presumably nonperforated, esophageal ulcer was revealed. While recovering from anesthesia, the dog's condition acutely deteriorated, with absence of spontaneous respiration, severe tachycardia, hypotension, white\u2010pale mucous membranes, and hypothermia. Severe anemia was present, with hypovolemic shock likely secondary to acute, postprocedural bleeding. Medical management included rapid packed red blood cell transfusion, crystalloid fluid therapy, and tranexamic acid. Despite initial stabilization, several hours later, the dog suffered cardiac arrest and cardiopulmonary resuscitation (CPR) was unsuccessful. At postmortem examination, a 1\u2010mm AEF was identified on the ventral aspect of the aorta that communicated with the overlying esophagus.<\/jats:p><\/jats:sec>New or Unique Information Provided<\/jats:title>Aortoesophageal fistulas should be considered in any patient with severe bleeding following esophagoscopy.
