Diagnosis and repair of peritoneopericardial diaphragmatic hernia (PPDH) in a Doberman dog: A first report from India

Abstract

Peritoneopericardial diaphragmatic hernia is one of the unusual developmental anomalies of diaphragm in dogs and cats, which are presented without any specific signs. Presented dog was examined clinically, physically and later subjected for chest radiograph and echocardiography for confirmation. Surgical repair was carried out through a midline celiotomy and the diaphragm was closed by opposing the margins in two layer using simple continuous pattern with polydioxanone suture material. Affected dog was showing normal temperature, elevated pulse and heart rate. Muffled heart sounds and barborygmi were detected on auscultation of chest. X-ray on left lateral exposure revealed loss of continuity of diaphragm along with gas filled radiolucent intestines within the pericardium and adjacent soft tissue structures of thorax. Presence of anechoeic area with hyperechoeic crystals within the pericardial space, diastolic collapse of right atrium and left ventricle were the echocardiographic features. Ultrasound guided thoracocentesis sample revealed alkaline pH (8.5). Surgical repair of the PPDH was performed through a midline celiotomy and the diaphragm was closed using simple continuous sutures with polydioxanone suture material.
