Impact of Intrasac Thrombus and a Patent Inferior Mesenteric Artery on EVAR Outcome

Abstract

In this series, type II endoleaks inhibited sac shrinkage and occurred more frequently in aneurysms without intrasac thrombus. Most type II endoleaks originated from lumbar arteries and not from the IMA. Prophylactic embolization of the IMA does not seem justified and is not always technically successful.
