Abstract

Large fistulas associated with impaired liver function should be treated by direct obliteration or removal of the shunt orifice. In a large shunt with the portal branch lying on the arterial branch, identification of the exact site of the fistula can be a challenge. We report a case of impaired liver function due to a large intrahepatic arterioportal fistula. The site of the shunt orifice could not be located accurately by preoperative imaging. However, intraoperative color Doppler ultrasonography and the simple regulation of arterial inflow clearly demonstrated the shunt orifice. This original technique has allowed the precise definition of the problem and has optimized the surgical treatment for this critical condition. Consequently, it should be considered a new option for the definition and management of large intrahepatic arterioportal fistulas.
