Surgical management of an incidentally diagnosed true pleuroperitoneal hernia in a cat

Abstract

Diaphragmatic defects in cats are common and most frequently occur as a result of trauma. Congenital diaphragmatic defects include peritoneopericardial hernias, hiatal hernias and, infrequently, true diaphragmatic, or pleuroperitoneal, hernias. Only three reports of feline pleuroperitoneal hernias could be found in the veterinary literature. All of these cats presented for evaluation of respiratory distress and two were managed successfully with surgery. This report describes the incidental diagnosis and successfully surgical treatment of a pleuroperitoneal hernia in a cat. It highlights the fact that pleuroperitoneal hernias may not always be symptomatic and that they may not be as rare as previously considered.

“…However, the hernia was an incidental finding in one patient (Cariou et al, 2009). The authors also hypothesized that congenital diaphragm defects are not as rare as mentioned in current literature, as more animals can be asymptomatic and live a normal life.…”

“…Diaphragmatic defects occur most commonly due to trauma, but may also be associated with congenital abnormalities such as peritoneopericardial hernia, hiatal hernia, and less frequently, pleuroperitoneal hernia (Cariou et al, 2009). Congenital diaphragmatic hernias are developmental defects of the diaphragm that allow the passage of abdominal viscera into the chest.…”

“…In pleuroperitoneal hernias, the synthesis of collagen and muscular tissue that divides the pleura and peritoneum ceases prematurely in the embryonic phase (Cariou et al, 2009), and the transverse septum or pleural and peritoneal folds do not fuse. Thus, an incomplete diaphragm that allows the free displacement of viscera is formed (Thrall, 2010).…”

“…Thus, an incomplete diaphragm that allows the free displacement of viscera is formed (Thrall, 2010). The serous surface of the thoracic diaphragm remains intact, preventing direct communication between the pleural and peritoneal cavities (Cariou, 2009). …”
