IntroductionThe main purpose of occluding a ruptured aneurysm is preventing rebleeding, which may be fatal. Microsurgical or endovascular treatments are the main approaches adopted to prevent new bleeding. Among patients presenting with aneurysmal SAH, about 50% had permanent injuries. Cognitive changes are one of the main morbidities from that illness. The type of treatment for the aneurysm (clipping or coil embolization) can also contribute to the genesis of those complications.ObjectiveAssessing language and verbal memory changes resulting from the aneurysmal lesion occlusion procedures, as well as establish which treatment offers less cognitive sequels.MethodThis investigation was carried out in Hospital da Restauraçã o, Recife-PE, from May, 2007 to November, 2009. One hundred and fifty-one patients were divided into two groups, surgical and endovascular, and had their language, fluency and verbal memory functions tested at two timepoints, pre- and post-operation. The results of the initial assessment and of the one occurring after the treatment were compared, between both groups and to each other.Results and conclusionsOne hundred and fifty-one patients were assessed, distributed as 122 surgical and 29 coil embolized. The performances in both groups did not differ in the initial assessment. However, Endovascular treatment doesn't show additional cognitive impairment and had a better performance in language and verbal memory, when compared to patients submitted to surgical treatment in an early post-operative period.
