Resumen

Objectives: Renal Artery Aneurysms (RAA) affect approximately 0.01%–0.97% of the population. Early diagnosis, thorough 3D-preoperative planning, and timely surgical treatment may offer effective and safe management. Methods: We report the open reparation of a segmental renal artery saccular aneurysm close to the bifurcation with detailed preoperative planning based on 3D printing, and with successful postoperative results. Results: We report the case of a 36-year-old man with a 3.5 × 5 cm segmental renal artery saccular aneurysm close to the bifurcation, for which endovascular management was ruled out and open management was chosen with detailed preoperative planning based on 3D printing and with successful postoperative results. Conclusions: 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. © The Author(s) 2024.
