Purpose: To describe a new type of stent consisting of a 3-dimensional (3D) braided tube made of 2 interconnected layers without any covering to treat a renal artery aneurysm.
Case Report: A 78-year-old hypertensive man with multiple comorbidities was incidentally found to have a large (28- x 30 mm) saccular aneurysm in the main right renal artery involving the inferior renal artery. Via a percutaneous femoral approach, a 6- x 30-mm Multilayer stent was deployed easily in front of the aneurysm neck covering the inferior renal artery.
