Transient reduction in renal function following arteriography: a radionuclide study

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.
