An extrahepatic arterioportal fistula (APF) involving the gastroduodenal artery and superior mesenteric vein is rare and mostly results from iatrogenic injuries.The clinical symptoms associated with APFs may include abdominal pain,gastrointestinal bleeding,ascites,nausea,vomiting,diarrhea,or even congestive heart failure.We present the case of a 70-year-old man who presented with chronic abdominal pain and gastrointestinal bleeding secondary to APF and portal vein thrombosis.The endovascular embolization of APF was accomplished successfully,and symptoms of portal hypertension resolved immediately after intervention.Unfortunately,the patient did not respond well to anticoagulation therapy with warfarin.Therefore,the patient underwent implantation of a transjugular intrahepatic portosystemic shunt,and the complications of portal hypertension resolved.In conclusion,the embolization of APF is technically feasible and effective and can be considered the first-choice therapy in selected patients.
