title: Hemorrhagic pleural effusion secondary to an unusual type III hiatal hernia in a 4-year-old great dane.
abstract: An unusual case of combined axial and paraesophageal (type III) hiatal hernia (HH) in a 4-year-old Great Dane is reported. The main presenting complaint was dyspnea, and no history of trauma was present. A tentative diagnosis of HH with secondary pleural effusion was made based on clinical signs and radiographic findings. Exploratory celiotomy revealed herniation of the gastric cardia, fundus, and body through the esophageal hiatus and an adjacent, distinct defect in the diaphragm. Rupture of the short gastric vessels lead to the formation of a hemorrhagic pleural effusion that impaired ventilation. The esophageal hiatus was surgically reduced in size, and the second defect was closed with nonabsorbable sutures. Esophagopexy and tube gastropexy procedures were also performed. The dog was clinically normal 9 months postoperatively. This type of HH is not currently defined within the traditional classification system and to the authors' knowledge has not been previously reported.
