Coil embolization for intrahepatic haemorrhage following liver biopsy in a patient with hepatitis C virus infection and hepatic microaneurysms.

ABSTRACT

Intrahepatic bleeding secondary to rupture of hepatic microaneurysms is an uncommon clinical entity more frequently associated with polyarteritis nodosa (PAN) or rarely with other vasculitis or autoimmune disease. Hepatic vasculitis is reported in chronic hepatitis C virus (HCV) infection and an association between hepatitis C and PAN is described. The current report presents the case of a middle-aged female patient with a medical history remarkable for HCV infection who underwent a percutaneous liver biopsy, which was complicated by severe intrahepatic and perihepatic haemorrhage. Computed tomography angiography revealed innumerous microaneurysms. She underwent transcatheter angiography and coil embolization of a peripheral branch of the right hepatic artery which controlled the bleeding. Subsequently, she was empirically treated with a course of Prednisolone. Follow-up imaging showed a good response to treatment.
