The presence of bilateral iliac aneurysms extending to the iliac bifurcations, in conjunction with an abdominal aortic aneurysm, complicates endovascular repair because of the difficulty of preserving one or both hypogastric arteries. Several open techniques have been suggested for hypogastric preservation, but they usually involve some type of anatomic or extra-anatomic bypass. Endovascular techniques for hypogastric preservation include branch iliac grafts, chimney grafts, and bellbottom limbs. We report the use of a Viabahn stent graft (W. L. Gore and Associates, Flagstaff, Ariz) within the iliac limb of a Powerlink device (Endologix, Inc, Irvine, Calif) to preserve a hypogastric artery.
双侧髂动脉瘤延伸至髂分叉处，并伴有腹主动脉瘤，这使得血管内修复变得复杂，因为难以保留一条或两条骼内动脉。已经提出了几种开放技术来保留骼内动脉，但它们通常涉及某种解剖或解剖外旁路。用于保留骼内动脉的血管内技术包括分支髂动脉移植物、烟囱移植物和喇叭腿支。我们报告了在 Powerlink 装置（Endologix，Inc，加利福尼亚州欧文）的髂支内使用 Viabahn 支架移植物（戈尔公司，亚利桑那州弗拉格斯塔夫）来保留骼内动脉。
