Iopromide-induced encephalopathy following coronary angioplasty

Abstract

Non-ionic agents have pharmacological side effects, such as seizure, alteration of cerebral function, confusion, short-term memory loss, mental aberrations and ophthalmoplegia. In this report, we present two cases that developed contrast-induced encephalopathy following coronary angioplasty by the non-ionic contrast agent, iopromide (Ultravist® ). As a result, we concluded that iopromide-induced encephalopathy may occur during angioplasty in patients with no particular predispositions. In addition to that, contrast-induced encephalopathy should be considered as a new-onset neurological disorder.
