    Delayed renal revascularization can restore function to kidneys that have been nonfunctional for extended periods. This case study challenges traditional timelines for successful kidney revascularization procedures.

    Area of Science:

    • Nephrology
    • Vascular Surgery
    • Medical Imaging

    Background:

    • Traditional surgical teaching posits that renal nonfunction exceeding a few days typically contraindicates revascularization success.
    • Previous reports have indicated the efficacy of delayed renal revascularization in specific patient cohorts.

    Observation:

    • A case involving a patient with complete atheromatous renal artery occlusion, leading to 30 days of verified renal nonfunction.
    • Diagnostic assessments including intravenous pyelogram, renal scan, and ureteral catheterization confirmed the prolonged nonfunction prior to intervention.

    Findings:

    • Surgical correction of the renal artery occlusion was performed.
    • Postoperative evaluations at six weeks and 18 months demonstrated a return to normal bilateral renal function.

    Implications:

    • The findings suggest that current temporal limitations for renal tissue preservation during revascularization may be overly restrictive.
    • Successful revascularization is potentially achievable even after prolonged ischemic periods, broadening the scope for kidney salvage.
