[Aneurysms of the hepatic artery. Clinico-radiologic study].

A series of 7 cases of hepatic artery aneurysm is reported, pointing out the different features for etiology, localization, shape and size. The diagnostic imaging methods are then analyzed. Conventional radiology is actually useless. Sonography is hardly ever conclusive, even if the association of real time-US with echo-Doppler is likely to be promising. CT often concludes the diagnostic procedure, though the small size of aneurysms may limit its efficacy. Arteriography is the only method fit to occasionally find out small aneurysms and clear eventual diagnostic doubts; it's also mandatory before surgical treatment and allows percutaneous embolization. MR is likely to offer interesting perspectives.
