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.
髂总动脉（CIA）动脉瘤延伸至髂内分叉和髂内动脉（IIA）通常需要排除 IIA，从而暴露盆部缺血性并发症的风险。本病例报告介绍了一种血管内技术，即在短的近端着陆区使用带更长的裸支架的覆膜支架进行“交叉支架”，将 CIA 动脉瘤完全排除，裸支架延伸至 IIA 的一个分支，保持盆部循环完整。髂外动脉至 IIA 的交叉支架加用一个裸支架需要进一步研究，因为它似乎扩大了移植物支架放置的适应证，增加了稳定性，并有助于避免 IIA 的排除。
