Various etiologies of hepatic artery pseudoaneurysm have been reported but regardless of the etiology hepatic artery pseudoaneurysm is usually managed with an endovascular approach or open surgery depending on the location and clinical symptomatology. However it is difficult to manage hepatic artery pseudoaneurysm after percutaneous transhepatic portal embolization since embolization of the hepatic artery may cause hepatic infarction Case presentation A 58-year-old Japanese man with hilar bile duct cancer underwent percutaneous transhepatic portal embolization to expand the indication for hepatic resection. Two days after percutaneous transhepatic portal embolization our patient suddenly complained of abdominal pain. Contrast-enhanced computed tomography confirmed a pseudoaneurysm arising from a segmental branch of his right hepatic artery. Since embolization of the hepatic arterial branches may cause hepatic infarction ultrasound-guided thrombin injection therapy was successfully performed for the pseudoaneurysm. Conclusion We performed a thrombin injection instead of arterial embolization to avoid hepatic infarction. The rationale of this choice may be insufficient. However ultrasound-guided percutaneous thrombin injection therapy may be considered as an alternative to percutaneous transarterial embolization or surgical intervention for an iatrogenic hepatic artery pseudoaneurysm. Introduction Percutaneous transhepatic portal embolization PTPE is often performed to .
