| 英文描述 | Communication between the peritoneal and pericardial cavities can allow abdominal organs to enter the pericardial sac. Although in some cases the lesion is asymptomatic and an incidental finding on routine radiography, the clinical signs seen are those of respiratory impairment, gastrointestinal disease, or congestive heart failure. The cardiac silhouette is enlarged on radiography, and loops of bowel may be seen on plain films or barium studies. Dyspnea is often worsened with elevation of the hindquarters and improved with elevation of the forequarters. This defect has been seen in association with abdominal hernia, sternal, diaphragmatic, and cardiac defects |
