Percutaneous transhepatic embolization of an intrahepatic pseudoaneurysm following liver biopsy in a liver transplant patient.

A 41-year-old liver transplant patient had severe hemobilia from an intrahepatic pseudoaneurysm secondary to a liver biopsy. Selective intra-arterial embolization was not technically possible due to marked redundancy and tortuosity of the allograft hepatic artery. The pseudoaneurysm was localized by ultrasound and embolized using a direct percutaneous transhepatic approach. This is a novel way of approaching hemobilia in liver transplant patients after liver biopsy and may avoid the risks of arterial embolization.
