Target lesion characteristics in failing vein grafts predict the success of endovascular and open revision.

Objectives: This study examined the association of anatomic and temporal characteristics of graft-threatening lesions with the efficacy of percutaneous and open graft revision for failing infrainguinal vein grafts.

Methods: Consecutive open and endovascular revisions for graft threatening lesions were reviewed. We evaluated graft durability and individual target lesion response to open and endovascular treatment to determine characteristics that may influence outcomes.

Type 2 endoleaks after abdominal aortic aneurysm stent grafting with systematic mesenteric and lumbar coil embolization.

We evaluated the results of our policy of systematic coil embolization of the inferior mesenteric artery (IMA) and/or lumbar arteries (LAs) prior to endovascular abdominal aortic aneurysm (AAA) repair (EVAR). We retrospectively reviewed all patients undergoing EVAR over a 4-year period at one hospital. Results were analyzed using uni- and multivariate analyses.
