A very rare case of encephalopathy in a patient with end-stage renal disease: Contrast agent, ioversol

Abstract

Contrast agents are associated with a number of adverse effects, including central nervous system effects. These agents are primarily filtered and excreted by the kidney. Contrast-associated encephalopathy is a rare complication. We report the case of a 55-year-old male on chronic hemodialysis who developed confusion and agitation after receiving ioversol during abdominal angiography. Although hemodialysis was performed his healing took 15 days. Patients with end-stage renal disease may be at an increased risk of adverse effects of contrast agents. © 2010 Informa UK Ltd.
