Background : Diaphragmatic rupture is a critical condition frequently encountered in small animal practice. It typically arises from trauma leading to a breach in the diaphragm and subsequent herniation of abdominal organs into the thoracic cavity. This condition often results in severe respiratory and cardiovascular compromise due to compression of thoracic structures. Immediate recognition and management are essential, as untreated cases will often die. The nature of this condition highlights the importance of a systematic approach to achieve the best outcomes. Aim of the article : This article aims to provide veterinary surgeons with a comprehensive and practical guide to managing diaphragmatic rupture in practice. It addresses key aspects including pathophysiology, clinical presentation, diagnostic approaches and perioperative management, with the aim of improving patient survival and facilitating successful recovery.
