The diagnosis and therapy of splenic and hepatic artery aneurysms is b
esides clinical findings based on ultrasound and selective arteriograp
hy. Surgical treatment depends on the exact localization of the aneury
sm. Because of postsplenectomy sepsis preservation of spleen should be
reached. Otherwise splenectomy with resection of the aneurysm must be
performed. If the aneurysm is localized at the common hepatic artery
ligation of the vessel is possible. The interposition of an autologous
vein graft is the most favorable proceeding in aneurysms of proper he
patic artery. Those of intrahepatic arteries should be treated just as
aneurysms in high risk patients by selective percutaneous embolizatio
