title: Embolization of hepatic artery pseudo-aneurysm facilitated by selective injection of thrombin and thrombin-soaked coils.
abstract: A case of recurrent haemobilia due to a pseudo-aneurysm of the right hepatic artery is presented. The patient required long-term anticoagulant therapy and, in order to achieve rapid haemostasis, thrombin was used as an adjunct to coil embolization. Rapid thrombosis of the pseudo-aneurysm occurred after selective injection of 200 units of thrombin, and thrombin-soaked coils were employed to occlude the arterial supply.
