Background: 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. Case report: A 68-year-old man who had already had several previous aortic surgeries underwent endovascular treatment for a 41 mm isolated right IIA aneurysm. Two Viabahn VBX (W. L. Gore & Associates, Flagstaff, AZ) covered stents (7 × 79 mm and 8Lx59 mm) were placed from a 6 mm gluteal artery to an 11 mm 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 13 mm, and circularity was maintained along the whole stent length, even in zones of higher centerline curvature. Conclusions: The Viabahn VBX covered stent could be used to treat aneurysms of the IIA.

Abstract
Background: 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. Case report: A 68-year-old man who had already had several previous aortic surgeries underwent endovascular treatment for a 41 mm isolated right IIA aneurysm. Two Viabahn VBX (W. L. Gore & Associates, Flagstaff, AZ) covered stents (7 × 79 mm and 8Lx59 mm) were placed from a 6 mm gluteal artery to an 11 mm 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 13 mm, and circularity was maintained along the whole stent length, even in zones of higher centerline curvature. Conclusions: The Viabahn VBX covered stent could be used to treat aneurysms of the IIA.
