Iliac Endoconduit: Application in Unfavorable Iliac Anatomy to Facilitate Emergency Abdominal Aortic Aneurysm Repair

Abstract

Extensive occlusive ilio-femoral arterial disease may be considered a contraindication to endovascular aortic aneurysm repair. Recent technical innovations describe the use of an "internal endoconduit" to navigate challenging iliac anatomy. Internal endoconduit is a technique in which "controlled rupture" of the external iliac artery using a covered stent allows controlled trans-femoral passage of the delivery sheath for endovascular aneurysm repair (EVAR). Here, we present two cases where iliac endoconduit was used to overcome unfavorable iliac artery anatomy in the setting of an emergency EVAR.
