Venous aneurysm in a horse.
Venous aneurysm was diagnosed in a 3-year-old horse, using contrast radiography and acid-base analysis of blood samples taken simultaneously from the right jugular vein and a swelling in the right mandibular angle. Attempted surgical correction was followed by rupture of the right maxillary vein. Hemorrhagic shock developed, and the horse died.
