M a i l i n g A d d r e s s : F r e d e r i c o T. U l t r a m a r i @@@@@@@@@@@@@@@@@@@@@@@@@@@ It is estimated that 6,000 and 2,000 cardiac catheterization procedures per million inhabitants/year are performed in Western countries for diagnostic and therapeutic purposes. In order to perform these procedures, 1,800 tons of iodine are required all over the world to manufacture contrast media (CM). The number of procedures that require the use of contrast media (or dye) has increased over time, and the population submitted to it is growing older, presenting more comorbidities 1, 2. Currently low-osmolar contrast media are used in approximately 75% of patients and the iso-osmolar contrast media, allegedly less toxic are becoming more popular 1. In spite of development of new contrast media, they still represent the third main cause of nosocomial-acquired acute renal failure (ARF) (10% of cases), substantially increasing hospitalization period, care costs and in-hospital morbi-mortality 3-6. The main goal is to address important aspects about the contrast-medium induced nephropathy (CMIN) that follows cardiac catheterization, including its definition, pathogenesis, incidence, risk factors, clinical picture, prevention, treatment and prognosis.

“…25 Additionally, allergic reactions may occur in brain tissues as contrast agents remain in the brain. Similarly, other studies have related the use of contrast media to the deterioration of neurological function and conditions such as posterior reversible leukoencephalopathy, [26][27][28][29] aseptic meningoencephalitis, 30 and iodinated contrast encephalopathy. 31 Second, contrast extravasation is more likely to occur in patients with failed recanalization, which is related to poor AIS outcome.…”

“…Most likely, the blood-brain barrier becomes damaged, which allows the contrast agent to express a direct neurotoxic effect on nerve cell membranes in the occipital lobes [1]. In the majority of cases described so far, the computed tomography image showed post-contrast enhancement in the occipital lobe, which may be related to body position during coronary angiography.…”

“…Cerebrovascular complications of coronary angiography and PCI are rare and usually include transient ischemic attacks (TIA) or stroke and affect approximately 0.4% of all patients undergoing PCI [1, 2]. These complications occur more often in some specific groups of patients: in the elderly, in female patients, in patients with diabetes mellitus type 2, in those with diffuse atherosclerosis, in patients undergoing coronary artery bypass grafting, in patients with peri-procedural complications (artery dissection) and in patients with no-reflow who often require intra-aortic counterpulsation [2].…”

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.
