Aneurysms of the intestinal arteries are, with an incidence less than 0.1%, rare vascular disorders. The aneurysm of the splenic a. is seen in 60% of the cases. Next are the hepatic and superior mesenteric a. aneurysm with 20 and 6%. The causes are among others mediadegeneration, arteriosclerosis, and infection. The most intestinal aa aneurysms are asymptomatic and accidentally discovered by angiography. Their importance is given by the risk of rupture, which varies between less than 2% and more than 50%. The treatment consists of exclusion with or without reconstruction, aneurysmorrhaphy or embolisation. Only the elective treatment can prevent a rupture with its high mortality.
