Traumatic abdominal hernias or eventration are defects in the wall of the abdomen associated with blunt trauma or punctiform trauma that allow protrusion of abdominal contents. Most abdominal hernias can be repaired by suturing torn muscle edges, although some large tissue lose or edges retraction must be necessary to use a muscle flap even though biological or synthetic implants. This article describes the use of bubaline fascia lata preserved in glycerin 98% to repair a traumatic abdominal hernia in a dog with 26kg, 10 years old, that was seen at Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul. Afterwards clinical and ultrasonography exam the wall rupture of the left abdomen and protrusion of abdominal contents. The patient was led to surgical treatment where at the first attempt was tried the apposing the disrupted muscle edges to prime suture. It was impossible because the large defect does not allow. Therefore, the biological membrane was used like an option to close the defect. The implant was sutured to the muscle edges with mononylon thread in a Sultan pattern. This implant allows a total occlusion of the abdominal defect given adequate sustentation. This patient was seen for six months after the surgery and he had none signal of hernia recurrence. Thus, we can conclude that bubaline fascia lata preserved in glycerin 98% is a viable alternative to treatment this injury.
