Inferior Mesenteric Artery Reimplantation

When the aortic aneurysm is entered, the orifice of the inferior mesenteric artery should be inspected. If pulsatile backbleeding is noted, it is usually safe to oversew the origin of the inferior mesenteric artery. The orifice is suture ligated from within the aneurysmal lumen to avoid injury to its branches, especially at the junction of the left colic to the sigmoidal and superior rectal branches.
