[An aneurysm of the inferior mesenteric artery associated with obstruction of the superior mesenteric artery and the celiac trunk].

The exact prevalence of visceral arteries aneurysms is not well documented and its is mainly known from necropsies. Inferior mesenteric artery aneurysms are the rarest of visceral aneurysms. The authors report a case of an aneurysm of the inferior mesenteric artery in a 52-year-old man with obstructive disease of superior mesenteric artery and celiac axis. The diagnosis was made by angiography. The aneurysm was resected with superior and inferior mesenteric arteries revascularization. Surgical approach is needed in these aneurysms and when they are associated with obstructive disease of other intestinal artery, revascularization is mandatory.
