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

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.
