A 59-year-old man underwent liver radiofrequency ablation under laparotomy for recurrent hepatic carcinoma located in the caudate lobe,however,near-fatal bleeding occurred 1 wk after the operation.The intraoperative ultrasound study during laparotomy revealed left hepatic artery pseudoaneurysm.Suture and packing with ribbon gauze was used to obtain hemostasis.A secondary hemorrhage followed 11 h later and hepatic angiography was performed immediately.Bleeding from the pseudoaneurysm in a branch of the left hepatic artery was found and the artery branch was embolized with coils.Other than slight bile leakage,post-embolization continued satisfactorily.Bleeding did not reoccur.The follow up visit 1 mo later found the pseudoaneurysm disappearing and no tumor recurrence.
