Retrospective analysis of acquired diaphragmatic hernia in dogs and cats
Data on dogs and cats that underwent surgery for a traumatic diaphragmatic hernia were retrospectively collected and analyzed, with an objective to identify factors that influenced the survival rate.
Researchers included 49 dogs and 48 cats in the study. The predominant respiratory clinical sign was dyspnea, and the interval from trauma to development of clinical signs did not influence patient survival. Concurrent orthopedic and/or soft tissue injuries were identified in 48.45% of the animals. Intraoperative complications occurred in 14 dogs and five cats and postoperative complications in seven dogs and six cats. Intraoperative death occurred in 6.2% and postoperative death in 8.3% from one hour to 10 days after surgery.
In conclusion, animals that received surgical treatment within 48 hours after diagnosis had a lower risk of death. Conversely, concurrent injuries and intraoperative and postoperative complications were the main factors associated with a higher risk of death.
