contrast nephropathy
Pronunciation: neh-FROP-ah-thee
Acute kidney injury that occurs following administration of iodinated contrast material.
Full Definition
Contrast nephropathy, also known as contrast-induced nephropathy (CIN) or contrast-associated acute kidney injury (CA-AKI), is a complication characterized by acute deterioration in renal function following exposure to iodinated contrast media used in vascular imaging procedures. The condition typically manifests as a rise in serum creatinine within 48-72 hours of contrast administration. Risk factors include pre-existing kidney disease, diabetes, dehydration, and high contrast volumes. Prevention strategies include adequate hydration, use of low-osmolar contrast agents, and limiting contrast dose. This complication is a significant consideration in planning contrast-enhanced vascular imaging studies.
Usage
Usage note: Include baseline and post-procedure creatinine values when documenting.
