Peritoneopericardial diaphragmatic hernia in adult dog

A two-year-old pointer dog showed a liver failure for long duration. By radiographic examination, barium or gas filled intestine was detected in the pericardium. Although liver function was bad, surgery was tried to repair hernia due to the poor prognosis. Intestine, omentum, and liver with gall bladder were dislocated in the pericadial sac by peritoneopericardial diaphragmatic hernia (PPDH). Intestine was easily removed from pericardial sac but omentum and liver were not because of strong adhesion to the pericardial sac. Postmortem examination was performed because the patient was died after surgery. Grossly, herniated liver whose right medial lobe was strongly adhered to the pericardial sac was severely congested with fibrin adhesion on the surface. Hypoplastic abnormally up-located heart had a fissure in the outside of lower right venticulum bordered apex and depressed large vessels including vena cava and aortic arch into the base of heart. It was suggested that formation of a fissure and depression of vessels might be due to the pressure of herniated organs. In the veterinary literature as far as we knew, PPDH associated with liver failure due to adhesion of liver to the pericardial sac has not been reported.
