Background: Large hepatic artery aneurysms are rare, especially spontaneous ones without history of hepatopancreatobiliary surgery or trauma. They are serious and need attention due to risk of spontaneous rupture. Management depends on local expertise with endovascular management being the preferred option, and surgical repair usually reserved to ruptured aneurysms in hemodynamically unstable patients. Methods: A 54-year-old female patient was referred to our hospital for treatment of incidentally discovered large hepatic artery aneurysm without obvious etiology. The decision was made to attempt percutaneous endovascular management at the interventional radiology unit. Result: The aneurysm sac was successfully excluded using covered stents. This was complicated by right hepatic artery occlusion and clinically insignificant contrast extravasation. These complications did not have any clinical sequel in terms of hemodynamic stability or impaired liver function. The patient was safely discharged few days after the procedure. Conclusion: Endovascular management of spontaneous large hepatic artery aneurysms is effective. Potential complications include hepatic artery occlusion and dissection, which may or may not have serious clinical consequences. This offers a less invasive treatment option compared to surgery.
