    Iodinated contrast agents can negatively impact kidney function, particularly effective renal plasma flow, in patients undergoing arteriography. The severity of this renal dysfunction is linked to the contrast dose and patient

    Area of Science:

    • Nephrology
    • Radiology
    • Pharmacology

    Background:

    • Iodinated contrast agents are widely used in arteriography.
    • Assessing the impact of these agents on renal function is crucial for patient safety.

    Purpose of the Study:

    • To evaluate the effects of iodinated contrast agents on kidney function in patients undergoing arteriography.
    • To identify specific renal parameters affected by contrast administration.

    Main Methods:

    • Serial radionuclide renograms were performed on 11 patients before and after arteriography.
    • Glomerular filtration rate, effective renal plasma flow, and filtration fraction were calculated.

    Main Results:

    • Effective renal plasma flow was the renal parameter most adversely affected by iodinated contrast agents.

  • Renal dysfunction severity correlated with the amount of contrast medium used.
  • Pre-existing renal disease and injection site may also influence the degree of renal dysfunction.

    • Conclusions:

    • Iodinated contrast agents can cause transient renal dysfunction, primarily affecting effective renal plasma flow.
    • Careful consideration of contrast volume and patient's renal status is recommended during arteriography.
