SUCCESSFUL CONSERVATIVE TREATMENT WITH TRANSARTERIAL EMBOLIZATION FOR INTRAHEPATIC ARTERIOPORTAL FISTULA DUE TO BLUNT LIVER INJURY

Abstract

　　A 25-year-old male was involved in a traffic accident while riding a motorcycle. He was transferred to our hospital and was diagnosed with blunt liver injury and pulmonary contusion. Abdominal angiography showed liver injury on the right lobe with arterioportal (AP) fistula, and emergency transarterial embolization (TAE) was performed for the posterior branch of the hepatic artery using absorbable gelatin sponge. Although repeated TAE (three times in total ; on admission, day 9, and day 16) was performed, AP fistula was still present on hospital discharge. Follow-up abdominal computed tomography (CT) at 14 months after injury showed that the AP fistula had disappeared. In this case, conservative management and TAE were effective to solve the blunt liver injury with AP fistula.
