ABSTRACT
Splanchnic artery aneurysms involve the celiac, superior mesenteric and inferior mesenteric arteries and their branches. ey occur relatively infrequently when compared to aneurysms of the aorta and iliac vessels, partly because there is a lower overall incidence of atherosclerosis in the splanchnic circulation. Atherosclerosis, associated with the great majority of aortic and iliac aneurysms, is present in less than half of splanchnic artery aneurysms. Whilst atherosclerosis can be found in some splanchnic artery aneurysms, it is thought to be a secondary process.1
