Its pathophysiology has recently been related to surgically induced damage of carotid baroreceptors.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Case Description<\/jats:italic>\n            A 45-year-old normotensive man with no history of epilepsy was admitted 3 weeks after bilateral carotid endarterectomy for severe repetitive paroxysmal headaches, vomiting, and agitation that were closely associated with attacks of marked hypertension. During one of these attacks, he had a grand mal seizure. Plasma catecholamine levels during hypertensive attacks were highly elevated despite the absence of pheochromocytoma, reflecting abnormalities in baroreceptor sensitivity that lead to unrestrained activation of the central sympathetic nervous system. Heart rate response to Valsalva maneuver showed suppression of the usual tachycardia, indicating baroreceptor reflex insensitivity.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            We report the first case of hypertensive encephalopathy associated with baroreflex failure syndrome after bilateral carotid endarterectomy. The role of blood pressure monitoring may be critical in revealing carotid baroreceptor insensitivity in such clinical settings.\n          <\/jats:p>","DOI":"10.1161\/01.str.26.3.488","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:08:03Z","timestamp":1308341283000},"page":"488-491","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":62,"title":["Hypertensive Encephalopathy After Bilateral Carotid Endarterectomy"],"prefix":"10.1161","volume":"26","author":[{"given":"O.","family":"Ille","sequence":"first","affiliation":[{"name":"From the Service de Neurologie, Ho\u0302pital Lariboisiere, Paris, France."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Woimant","sequence":"additional","affiliation":[{"name":"From the Service de Neurologie, Ho\u0302pital Lariboisiere, Paris, France."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Pruna","sequence":"additional","affiliation":[{"name":"From the Service de Neurologie, Ho\u0302pital Lariboisiere, Paris, France."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"O.","family":"Corabianu","sequence":"additional","affiliation":[{"name":"From the Service de Neurologie, Ho\u0302pital Lariboisiere, Paris, France."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
