3D impression to facilitate in situ surgical renal segmental artery aneurysm repair: A novel open approach option for an unusual vascular condition.

When an open approach is chosen in the RAA treatment, a detailed study of the anatomical configuration of the RAAs is mandatory, and life-size 3D printing is a valuable tool that could contribute to the operative technique, reduce surgical times associated with renal ischemia and provide minute details that would make a clear anatomical difference during in situ repair.
