What is a common effect of renal failure on the use of contrast agents during arteriography?

In the context of renal failure, the use of contrast agents during arteriography poses a significant risk of severe complications, specifically contrast-induced nephropathy (CIN). When a patient has impaired renal function, the kidneys may struggle to clear the contrast agent from the bloodstream effectively. As a result, the contrast can remain in the system longer, potentially leading to further kidney damage and worsening renal function.

In patients with compromised renal function, the likelihood of experiencing adverse effects from contrast media increases. This includes not only the risk of contrast-induced nephropathy but also other complications such as allergic reactions, and those related to the vascular access itself. These elevated risks necessitate careful consideration before administering contrast agents, often leading clinicians to explore alternative imaging techniques when appropriate, or to take extra precautions such as hydration or the use of lower doses of contrast.

The other choices do not accurately reflect the clinical realities associated with renal impairment and contrast use during vascular imaging.
