Objectives: To highlight the incidence of hepatic pseudoaneurysms secondary to motor vehicle accidents and the rate of successful treatment with endovascular embolisation.

Methods: This was a retrospective study performed in a medical centre in Malaysia from January 2009 to January 2012. Cases were identified using the Integrated Reporting and Imaging System of the department and the angiographic unit server. Further details were collected from the patients’ medical records. All patients were followed up by the primary team for at least a year.

Results: There were five cases of hepatic pseudoaneurysms of which two developed arterioportal or arteriovenous shunts. All patients were young adult males with high-grade liver injury. Of these, only one was symptomatic and diagnosed by the presence of fresh blood in the surgical drain; the other four cases were diagnosed by incidental findings on follow-up computed tomography. All the cases were treated successfully with endovascular embolisation: two with glue embolisation and three with coil embolisation. Patients were followed up clinically for 1 year with no significant sequelae.

Conclusion: Hepatic pseudoaneuryms from motor vehicle accidents are a rare complication and, commonly, are incidental findings on follow-up computed tomography. Awareness of this complication is important; treatment with a procedure such as endovascular embolisation can prevent further complications.
