contrast nephropathy
Also written as: CIN — Contrast-Induced Nephropathy
Acute kidney injury occurring after intravascular contrast agent administration.
Full Definition
Contrast nephropathy, also known as contrast-induced nephropathy (CIN), is a form of acute kidney injury that develops following the administration of iodinated contrast media during vascular imaging procedures. This condition is characterized by a rise in serum creatinine levels within 48-72 hours of contrast exposure. Risk factors include pre-existing renal impairment, diabetes, dehydration, and high contrast volumes. Prevention strategies include adequate hydration, use of low-osmolar contrast agents, and careful patient selection. Contrast nephropathy is a significant concern in arterial vascular imaging due to the substantial contrast volumes often required.
Usage
