The radiological treatment of hepatic artery aneurysms.

Improvements in the quality and availability of cross-sectional imaging should result in more frequent detection of hepatic artery aneurysms before rupture. Interventional radiological treatment for extra-hepatic lesions has not previously been discussed in the literature. We present two cases of extra-hepatic hepatic artery aneurysms treated using different endovascular techniques and discuss the relative merits of these approaches.
