    In situ fenestration (ISF) is a reliable technique for complex endovascular aortic repair, particularly in urgent settings.

  • 2

    Electrified wire in situ fenestration (EWISF) is an affordable and precise alternative to traditional ISF methods.

  • 3

    The case study involved an 89-year-old man with a 54-mm pararenal abdominal aortic aneurysm and severe left renal artery stenosis.

  • 4

    Prolonged application of radiofrequency energy during EWISF improved technical feasibility and allowed successful catheter passage.

  • 5

    Postoperative imaging confirmed left renal artery patency and exclusion of the pararenal aneurysm after the procedure.
