Abstract
We report endovascular treatment of a patient with an isolated Internal Iliac Artery (IIA) aneurysm who was treated by positioning a novel covered stent that could adapt to different proximal and distal diameters. A 68-year-old man who had already had several previous aortic surgeries underwent endovascular treatment for a 41mm isolated right IIA aneurysm. Two Viabahn VBX (W. L. Gore & Associates, Flagstaff, AZ) covered stents (7×79mm and 8Lx59mm) were placed from a 6mm gluteal artery to an 11mm Dacron hypogastric artery via contralateral femoral surgical access. No complications occurred. One-month follow-up computed tomography angiography (CTA) scan showed the complete exclusion of the aneurysmal sac with spontaneous endoleak resolution and patency of the covered stents. Geometric analysis of the postoperative CTA highlighted VBX conformability to the native vessel. Maximum stented vessel diameter ranged between 9 and 13mm, and circularity was maintained along the whole stent length, even in zones of higher centerline curvature. The Viabahn VBX covered stent could be used to treat aneurysms of the IIA.
