Abstract:

Contrast-induced encephalopathy is a rare complication of endovascular injection of contrast agent.

Aim: was to analyze available medical literature data, concerning the contrast-induced encephalopathy prevalence, etiology and pathogenesis, clinical and imaging manifestation.

Materials and methods: publications with key words «contrast-induced encephalopathy» were selected in Pubmed (wwwpubmed.com). From 34 articles, 15 full-text articles with avaliable description of contrast-induced encephalopathy were selected. We analyzed cases of contrast-induced encephalopathy described in literature, presented main causes and pathogenesis, clinical manifestation and imaging findings, prophylaxis and treatment.

Results: development of this complication could be observed after injection of contrast agent into lumen either cerebral arteries or extracerebral ones. Based on the literature analysis, two main types of contrast-induced encephalopathy described: stochastic (accidental) and deterministic (predefined).

Conclusion: contrast-induced encephalopathy recognition, differential diagnostic with stroke and intracranial hemorrhage allow making correct prognosis and getting an adequate treatment tactics, when everything is done promptly.
