A retrospective study on diaphragmatic hernia in cats.

Diaphragmatic rupture is introduced as one of the most common injuries occurring in small animals. In our retrospective report, 14 cats with a mean age of 12 months (male = 8, female = 6) that underwent diaphragmatic herniorrhaphy were studied. The data included the following: age, sex, breed, and clinical signs. The cause of diaphragmatic hernia, diaphragmatic rupture area, herniated organs, concomitant injuries, and survival rate after surgical treatment were detailed. The cats included 11 domestic shorthair (DSH) and three Persian. Trauma was the most common cause of rupture in these patients and one 3-month old Persian cat had peritoneopericardial diaphragmatic hernia (PPDH). The most common clinical sign was dyspnea. Concurrent disorders included fractures of pelvic, long bones and ribs and mild pneumothorax. One of the five cats survived with concurrent disorders. In this study, the frequency of rupture sites was as follows: the right-side (11 cats), left-side (2 cats), and dorsal side of diaphragm in one case. The most frequently inserted organ into the chest was liver. In our study, the survival rate after surgical treatment was 71.00%. In conclusion, we suggested that stabilization of the patient was important before herniorrhaphy. Based on our study, the concurrent damages affected the survival rate.
