Late Transient Contrast-Induced Encephalopathy after Percutaneous Coronary Intervention

Cerebrovascular events are a recognized complication of cardiac catheterization, with various neurological symptoms. The incidence is estimated to be .3%-.4%.1 A much more infrequent complication is a contrast-induced encephalopathy (CIE) described about 50 cases in the literature. The pathogenesis is believed to be a direct neurotoxic effect causing an osmotic disruption of the blood –brain barrier.2,3 Risk factors are hypertension, diabetes mellitus, renal impairment, large volumes of contrast, and previous adverse reaction to iodinated contrast.
