Juxtarenal Inflammatory Aneurysm Treated with Bilateral Iliac-Renal Bypass Using the Gore Hybrid Device and Total Sealing of the Aneurysmal Sac with a Nellix Device.

The aim of this study is to present the treatment of a juxtarenal inflammatory aneurysm using a Nellix device (Endologix, Inc., Irvine, CA) to seal the entire aneurysmatic aorta combined with bilateral iliac-renal bypass using the Gore hybrid vascular graft (W. L. Gore & Associates, Inc., Flagstaff, AZ). A 63-year-old man was diagnosed with a 6-cm juxtarenal inflammatory aneurysm. It was initially decided to treat him with an aorto-aortic bypass and to revascularize the 2 renal arteries with "graft to renal artery bypass" using Gore hybrid vascular grafts. Due to the high intraoperative bleeding preparing the proximal neck and the tight adhesion of the aorta to the adjacent structures, we decided to change our plans and to treat the patient using the Nellix system combined with bilateral iliac-renal bypass using the Gore hybrid vascular grafts. Contrast computed tomography control at 1 month showed complete sealing of the aneurysm sac and patent iliac renal bypasses. The reported case demonstrated that the Nellix Endovascular Aneurysm Sealing system combined with Gore hybrid vascular grafts for bilateral iliac-renal bypass showed that it can be an effective modality for the treatment of juxtarenal, inflammatory aortic aneurysm and revascularization of the renal arteries from the distal iliac arteries.
