Abstract

Although rare, hepatic artery aneurysms are associated with a high morbidity and mortality, necessitating a prompt diagnosis. A significant proportion of hepatic artery aneurysms are pseudoaneurysms, and the major risk factors of which have already been identified in previous literatures. Presentation can be variable, but diagnosis almost relies entirely on computed tomography and digital subtraction angiography. The endovascular approach has progressively become the preferred option due to its better performance when compared to the traditional surgical approach. However, formulation of an endovascular treatment plan for these lesions remains difficult as multiple factors should be considered to identify the best endovascular treatment modality. Five cases of pseudoaneurysm due to recent Whipple operation, hepatobiliary infections, and underlying malignancy are presented in this article to illustrate the effectiveness and complexity of endovascular treatment in this disease entity.
