Contrast-Induced Encephalopathy after Percutaneous Coronary Intervention

Min-Tsun Liao et al. Acta Cardiol Sin. 2013 May.

Abstract

Contrast-induced encephalopathy (CIE) is a rare complication that presents with transient neurologic deficits and is caused by neurotoxicity of intravascular contrast media. The prognosis can be extremely favorable even in comatose patients. We reported a 76-year-old woman admitted for scheduled coronary angiography. The total amount of Optiray contrast media used was 150 mL. Immediately after the procedure, the patient developed consciousness disturbance, global aphasia, cortical blindness and right-sided weakness. CIE was diagnosed by computed tomography and subsequent magnetic resonance imaging. The patient recovered completely within 48 hours without any neurological deficits.

Key words: Angioplasty; Contrast-induced encephalopathy; Percutaneous coronary intervention.

Figure 1
A perfusion computed tomography shows no intracranial hemorrhage (A) or cerebral vascular obstruction (B).
Figure 2
Figure 2
Magnetic resonance imaging (MRI) showed hyperintensity at left centrum semiovale and high frontoparietal regions on T2 (A), diffusion weighted imaging (B) and fluid attenuated inversion recovery imaging (C). MRA (D) showed no occlusion of intracranial artery. No abnormal signal was detected in apparent diffusion coefficient (ADC) maps (E). And ADC maps in another patient with stroke showed significant reduction (F).
