Visceral arteries aneurysms are an uncommon pathology. Lienal artery (60%), hepatic (20%), superior mesenteric (5,9%) and tripod celiac (4%) are the most involved. Female predominance, portal hypertension, arteriosclerosis, pregnancy, traumatic and infective factors are the most remarkable etiopathogenetic factors. Portal hypertension with splenomegaly might be an important factor in the pathogenesis of intra- and extraparenchimal splenic artery aneurysms. Stress is laid on the importance of arteriography during portal hypertension in pregnancy as a preventive measure because the rupture of aneurysm of the splenic artery, despite laparotomy in emergency is often fatal, and of coeliac angiography prior to liver transplantation; if splenic artery aneurysm is found, ligation of the splenic artery should be performed at the time of transplantation to prevent possible rupture. The different roles of the imaging techniques used are examined.
