Immediately thereafter, we performed an abdominal CT, which revealed abnormal density shadows in the right hepatic lobe with possible hemorrhage (Figure 1).
Arteriography. (A) Selective arteriography of the hepatic artery showing a sac-like pseudoaneurysm. (B) Angiographic embolization of the right hepatic artery showing the pseudoaneurysm disappeared.

All these findings together with the history of laparoscopic hepatic rupture repair prompted the suspicion of HAP rupture, which was further confirmed by the presence of a sac-like pseudoaneurysm beginning from the front branch of the right hepatic artery on selective hepatic artery arteriography (Figure 2A). Repeat arteriography showed that the pseudoaneurysm disappeared (Figure 2B).
Abdominal contrast-enhanced computed tomography at discharge showing the pseudoaneurysm disappeared and the hyper-density coil (blue arrow). (A) Horizontal plane. (B) Coronal plane.

An abdominal contrast-enhanced CT (CECT) showed no enhanced pseudoaneurysm when he was discharged (Figure 3).
