RESUMEN
INTRODUCTION: Penetrating trauma is commonly seen in dogs. The severity depends on the site of injury and tissue involved. Junctional hemorrhage can be especially challenging to control given the inaccessibility of the damaged vasculature. Methods described to control life-threatening hemorrhage in dogs include direct pressure, hemostatic gauze, hemostatic powder or granules, wound packing, tourniquets, and direct clamping of the vasculature. Foley balloon catheters (FBC) are commonly used to tamponade deep vascular hemorrhage in people, but the technique has not been previously described in the veterinary literature. OBJECTIVE: To present a case of penetrating trauma (bite wound) in a dog with a transected left femoral artery and vein in which the life-threatening hemorrhage was initially controlled with tamponade using an FBC. CASE: A 7-year-old neutered male Terrier mix presented in hemorrhagic shock with an Animal Trauma Triage (ATT) of 7 and modifed Glasgow coma scale (MGCS) of 17 forty-five minutes after being attacked by another dog. The dog had sustained a deep penetrating wound to the left groin. Direct pressure and gauze packing at the site of injury were not successful at slowing the hemorrhage. A 10-Fr, 55-cm Foley catheter with a 5-mL balloon was inserted into the wound tract, and the balloon was inflated with 7.5 mL of sterile saline. Hemorrhage was controlled after inflation of the Foley balloon. CBC, blood biochemistries, abdominal point-of-care ultrasound, radiographs, prothrombin time, partial thromboplastin time, and whole blood viscoelastic testing were performed. Stabilization included fluid resuscitation, analgesics, antimicrobials, and epsilon aminocaproic acid. The dog was then anesthetized to definitively identify and control the hemorrhage. Transection of the left femoral artery and vein where identified and ligated. The dog fully recovered and was discharged 32 hours later. NEW AND UNIQUE INFORMATION: FBCs may be useful as an alternative technique for temporary control of life-threatening hemorrhage secondary to penetrating injuries in both the emergency department and prehospital settings.
