    Cerebral arteriography, a common diagnostic tool, carries risks beyond typical invasive procedures. A rare complication involves a retained, knotted catheter tip, successfully removed via femoral artery incision in this case.

    Area of Science:

    • Radiology
    • Vascular Surgery
    • Interventional Cardiology

    Background:

    • Cerebral arteriography is a standard diagnostic imaging technique for evaluating cerebrovascular diseases.
    • While generally safe, invasive procedures like cerebral arteriography can lead to specific complications.
    • Understanding potential risks is crucial for patient safety and procedural refinement.

    Observation:

    • A case of a retained, knotted distal flexible catheter tip during cerebral arteriography is presented.
    • This complication occurred despite the routine use of the diagnostic radiologic procedure.
    • The retained catheter presented a unique challenge requiring intervention.

    Findings:

    • The knotted catheter tip was successfully extracted.
    • Extraction was performed through an incision in the femoral artery.

  • This case highlights a rare but significant procedural complication.

    • Implications:

    • The findings underscore the importance of vigilance for rare complications during cerebral arteriography.
    • Successful surgical extraction demonstrates a viable management strategy for retained catheter fragments.
    • This case may inform procedural guidelines and training for interventional radiologists and surgeons.
