Abdominal aortic bifurcation anatomy and endograft limb size affect the use of adjunctive iliac stenting after bifurcated endograft deployment for abdominal aortic aneurysm

The aims of the study are(1)to define the incidence of intraoperative endograft limb stenosis >50%(ELS) after bifurcated EVAR,(2)to find risk factors for ELS considering morphology of aortic bifurcation and structural characteristics of endograft iliac limbs,(3)to evaluate early and follow-up outcomes of intraoperative adjunctive endograft iliac stenting.
