Evidence of Pneumopericardium after Elective Ovariectomy in a Peritoneopericardial Diaphragmatic Hernia-Affected Dog: A Case Report

Abstract

Peritoneopericardial diaphragmatic hernia (PPDH) is an opening between the pericardial sac and the pleuroperitoneal membrane. Pneumopericardium is an infrequent complication of PPDH. This condition is a serious circumstance in which free gas accumulates in the pericardial sac. The present report describes the occurrence of pneumopericardium and pericardial effusion after elective ovariectomy in a dog affected by PPDH. The presence of an umbilical and diaphragmatic hernia was highlighted during ovariectomy, and a pneumopericardium was seen during an X-ray exam. At the time of admission to the hospital, the dog was asymptomatic. The diagnosis was performed by X-ray and ultrasonographic exams. Computed tomography examination confirmed the diagnosis and directed for a surgical approach of the congenital defect. Surgery resulted in resolution of PPDH and of pneumopericardium.

Case report: Diagnosis and surgical treatment of delayed traumatic diaphragmatic hernia with hepatothorax and enterothorax in a small dog

“…Diagnosis of diaphragmatic hernia is mainly performed by conventional X-ray, contrast radiography (barium gavage) and ultrasonography ( 17 ). Chest radiograph may show the disappearance of the diaphragmatic outline, fluid or air-filled organs in the thoracic cavity, as well as the disappearance of normal lung fields, and an abdominal radiograph may show the absence of abdominal organs ( 15 ).…”
