Endovascular preservation of full pelvic circulation with external iliac-to-internal iliac artery "cross-stenting" in patients with aorto-iliac aneurysms.
Common iliac artery (CIA) aneurysms that extend into the iliac bifurcation and internal iliac artery (IIA) usually require exclusion of the IIA, exposing pelvic ischemic complication risks. This case report presents an endovascular technique of "cross-stenting" in a short proximal landing zone with complete exclusion of the CIA aneurysm using a covered stent graft with a longer uncovered stent extending into one branch of the IIAs, maintaining full pelvic circulation. External iliac artery to IIA cross-stenting with an additional uncovered stent warrants further investigation, because it seems to extend graft stent placement indications, increase stability, and help avoid IIA exclusion.
