Post-traumatic pseudoaneurysm of the hepatic artery is rare and usually occurs as a complication after abdominal trauma. We report a patient presenting with abdominal mass occurring 2 years after blunt abdominal trauma resulting from a pseudoaneurysm of the right hepatic artery. Computed tomographic scan and angiography demonstrated a pseudoaneurysm of the right hepatic artery. This patient had high risks and comorbidity for reoperation, therefore he was selected for conservative treatment by superselective microcoil embolization. He was well and discharged 3 days later. This suggested that this alternative treatment was safe and had low complication. In high-risk patients, we recommend non-surgical management (superselective microcoil embolization) as the treatment of choice for treatment of post-traumatic hepatic artery pseudoaneurysm.
