髂动脉分支装置（iliac branch device, IBD）是专为髂动脉分叉设计的分支支架，为主-髂动脉瘤、孤立性髂动脉瘤腔内治疗时重建髂内动脉血流的理想解决方案。北京大学人民医院血管外科利用自制的一枚IBD，成功治疗腹主动脉瘤腔内修复术（endovascular aneurysm repair, EVAR）后髂动脉瘤1例，其设计及植入较既往报道［1-3］均有独到之处，现将病例分享如下。

An involved internal iliac artery is usually embolized when performing endovascular aneurysm repair for aortoiliac or isolated iliac artery aneurysm.This can lead to complications such as buttock claudication,colon ischaemia and erectile dysfunction.Iliac branch device (IBD) is an endograft designed specifically for iliac bifurcation to preserve internal iliac flow. It was performed with high technical success rates and encouraging mid-term patency. Here we report a case of right iliac aneurysm developed 3 years after endovascular aneurysm repair for an aortoiliac aneurysm, with the patient’s left internal artery been sacrificed then. Using a handmade IBD, we excluded the aneurysm without occlusion of the ipsilateral internal iliac artery or any type of endoleak. Both the design and deployment of this IBD are distinctive that we would like to share our experience with all the colleagues.
