Hérnia diafragmática traumática em cão

The term diaphragmatic hernia refers to rupture of the diaphragm, the muscle that separates the thoracic and abdominal cavities. The diaphragm plays an important role in ventilation, serving as an inspiratory muscle, in addition to helping transport lymphatic fluid. Most diaphragmatic hernias in dogs and cats are caused by trauma, particularly being run over by a car. They are frequently diagnosed in small animal clinics and there is no age or species predisposition for traumatic diaphragmatic hernias. Symptoms vary but include difficulty breathing, tachypnea, pale or cyanotic mucous membranes, tachycardia and oliguria. The definitive diagnosis is confirmed by the combination of a well performed anamnesis and imaging tests such as radiography and ultrasound. The recommended treatment is surgery, with diaphragm surgery, combines with follow-up and post-operative care to ensure a good recovery. This work reports the case of a female puppy, ran over by a vehicle. After imaging tests, she was diagnosed with a diaphragmatic hernia and subsequently underwent diaphragmatic herniorrhaphy, a diaphragm correction procedure. The surgical procedure and the patient's recovery went well, without complications.
