Abstract

The concept that carotid disease may compromise cognitive function was initially proposed by Fisher in 1951, based on an autopsy case. However, some topics involving cognitive function remain controversial, such as its correlation with carotid obstructive disease. So, the authors of this review evaluate the impact of carotid revascularization on cognitive function and the repercussions of the revascularization technique (carotid stenting vs. endarterectomy) chosen. It was clear from the literature reviewed that carotid stenosis is related to a decline in cognitive function over time. However, controversy still remains over the impact of carotid revascularization on cognitive function. With elation to the technique employed (carotid stenting vs. endarterectomy), the majority of studies found no difference between the two techniques in terms of overall cognitive outcome.

Resumo

A noção de que a doença carotídea pode comprometer a função cognitiva foi proposta inicialmente por Fisher, em 1951, baseado em um caso de necropsia. Porém, alguns tópicos envolvendo a função cognitiva permanecem controversos, tais como sua correlação com a doença obstrutiva da carótida. Nesse sentido, os autores desta revisão buscam avaliar o impacto da revascularização carotídea e a repercussão da técnica de revascularização empregada (endarterectomia versusangioplastia carotídea) sobre a função cognitiva. A partir da literatura levantada, ficou claro que as estenoses carotídeas estão relacionadas com o declínio cognitivo ao longo do tempo, mas ainda há controvérsia no que se refere ao impacto da revascularização carotídea sobre a função cognitiva. Quanto à técnica empregada (angioplastia versusendarterectomia carotídeas), a maioria dos estudos não demonstrou distinção entre as duas técnicas quanto ao desfecho cognitivo geral.
