Coronary angiography is the current gold standard for the diagnosis of
ischemic heart disease and therefore the prevalence of percutaneous coronary procedures such as angiography and angioplasty is high. The occurrence of cerebral complications after coronary angiography and coronary angioplasty is low and it mainly includes
transient ischemic attack and
stroke. The prevalence of transient
cortical blindness after X-ray
contrast media is low and it is usually seen after cerebral angiography. Until now only a few cases of transient
cortical blindness have been described after coronary artery angiography. Regarding the spread of coronary angiography worldwide and in Poland this complication is uniquely rare. A 32-year-old man with multiple extrasystolic ventricular
arrhythmia suggesting
Brugada syndrome diagnosis according to morphology of the
left bundle branch block and with decreased left ventricular ejection fraction was admitted to the First Department of Cardiology and
Hypertension, Medical College of the Jagiellonian University in Krakow. Coronary angiography was performed in order to exclude ischemic etiology of the observed abnormalities. No arteriosclerotic lesions were found in coronary arteries. Transient
cortical blindness was observed directly after angiography which may have been caused by the neurotoxic effect of the used X-ray contrast medium. In ophthalmologic and neurologic examination as well as in the cerebral computed tomography scan no pathologies were found.
Visual impairment disappeared totally within several hours.
