The American Association of Surgery of Trauma uses computer tomography findings to classify them into grades I through VI. Grade I, II and III lesions have better prognosis, and may be successfully treated with conservative clinical approaches. Grade IV through VI typically require surgical intervention. The present article presents the efficacy of endovascular treatment of Grade V liver injury in the medium and long terms, describing the clinical stabilization in acute phases and maintenance of hepatic function during a 6-month follow-up. Case Report: A 26-year-old male victim of blunt abdominal trauma and grade V liver injury had a successful hemodynamical stabilization after being subjected to arteriographic selective embolization. A surgical approach was necessary later on to remove intraabdominal clots, with adequate post-surgical evolution. The patient kept under follow up at the outpatient clinic for six months after the traumatic event, with full recovery of liver function and enzymes. Conclusion: Non-surgical treatment of grade V hepatic lesion may be used in selected cases in centers with hemodynamic and intensive care units.
