Abstract
Headache associated with Carotid Endarterectomy (CEA) is a known condition; however, its incidence and etiology are not well defined. In this study, we determined the incidence and evaluated the characteristics of headache following CEA. This prospective study was conducted between January and July 2009, in 32 patients submitted to CEA. 68.7% of patients were male; mean age was 67.3 years-old. Headache incidence was 37.5%, ipsilateral to the CEA in 91% of patients; pressure was the most common pain quality (81.2%) and affected the frontal region alone in 37.5% of headache episodes. All headache episodes were of mild intensity. No correlation (p > 0.05) was found between sexes and no significant value (p > 0.05) was determined between the presence of headache and the mean degree of stenosis in the ipsilateral and contralateral carotid operated. Headache following CEA is a common condition; in most cases it is ipsilateral to the procedure, pressure type, mild and self-limiting.
