Abdominal CT was also performed and demonstrated RHA pseudoaneurysm with a diameter of 8 mm (Fig. 1a). Abdominal CT revealed that the size of RHA pseudoaneurysm increased to a diameter of 12 mm (Fig. 1b).
Images of findings before and after endovascular treatment of the right hepatic pseudoaneurysm.. (A) Emergency angiogram confirming a pseudoaneurysm emerging from the right hepatic artery to reconstruct the jejunum limb (arrow).. (B) Extravasation disappeared (arrow). Blood flow to the liver via the left hepatic artery was confirmed after coil embolization for the right hepatic artery.

Subsequently, an emergency abdominal angiography was performed, which demonstrated gastrointestinal bleeding due to RHA pseudoaneurysm (Fig. 2a). The patency from the common hepatic artery to left hepatic artery (LHA) was confirmed, and coil embolization for RHA was performed; consequently, his blood pressure immediately normalized and hepatic perfusion from LHA was confirmed (Fig. 2b).
Clinical course for postoperative days.. A total of 22 units of packed red cell concentrates were transfused since readmission.
