Aortic thromboembolism as a complication of gastric dilatation/volvulus in a dog.

An unusual complication of gastric dilatation/volvulus developed in a 10-year-old spayed Great Dane. An aortic thromboembolus lodged in the iliac artery bifurcation 4 days after admission and tube gastropexy to correct the condition. The dog was euthanatized after 48 hours of supportive care failed to elicit any improvement. Thrombus formation appeared to originate in the left ventricle; however, a primary cause could not be determined.
