自制髂动脉分支装置治疗腹主动脉瘤腔内修复术后髂动脉瘤1例

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。

Endovascular repair of an iliac artery aneurysm after endovascular aneurysm repair with handmade iliac branch device:a case report

SUMMARY An involved internal iliac artery is usually embolized when performing endovascular aneu -rysm 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 de-signed 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 ar-tery been sacrificed then .Using a handmade IBD , we excluded the aneurysm without occlusion of the ip-silateral internal iliac artery or any type of endoleak .Both the design and deployment of this IBD are dis-tinctive that we would like to share our experience with all the colleagues .
