We report a 55-year-old woman with recurrent cerebral vasoconstriction postoperatively. She had bilateral high-grade internal carotid artery stenosis and underwent right endarterectomy because of transient left-sided sensory symptoms. She developed a reperfusion syndrome with severe right-sided headache, right frontotemporal oedema and increased velocities in transcranial Doppler ultrasound. Given her gradual increase of velocities and Lindegaard index, together with fixed left sensory and motor deficits, we performed CT angiography, which suggested cerebral vasoconstriction syndrome. A subsequent left carotid endarterectomy triggered a similar cerebrovascular response. We highlight the need for continuous monitoring of cerebral haemodynamics following carotid endarterectomy.<\/jats:p>","DOI":"10.1136\/practneurol-2017-001871","type":"journal-article","created":{"date-parts":[[2018,6,6]],"date-time":"2018-06-06T12:25:52Z","timestamp":1528287952000},"page":"378-381","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Cerebral vasoconstriction after carotid endarterectomy"],"prefix":"10.1136","volume":"18","author":[{"given":"Diogo","family":"Fitas","sequence":"first","affiliation":[{"name":"Department of Neurology, Santa Luzia Hospital, Viana do Castelo, Portugal"},{"name":"Department of Neurology, S\u00e3o Jo\u00e3o Hospital Centre, Porto, Portugal"}]},{"given":"Marta","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Department of Neurology, S\u00e3o Jo\u00e3o Hospital Centre, Porto, Portugal"},{"name":"Faculty of Medicine of University of Porto, Porto, Portugal"}]},{"given":"Pedro","family":"Castro","sequence":"additional","affiliation":[{"name":"Department of Neurology, S\u00e3o Jo\u00e3o Hospital Centre, Porto, Portugal"},{"name":"Faculty of Medicine of University of Porto, Porto, Portugal"}]},{"given":"Pedro","family":"Abreu","sequence":"additional","affiliation":[{"name":"Department of Neurology, S\u00e3o Jo\u00e3o Hospital Centre, Porto, Portugal"},{"name":"Faculty of Medicine of University of Porto, Porto, Portugal"}]},{"given":"Goreti","family":"Moreira","sequence":"additional","affiliation":[{"name":"Stroke Unit of S\u00e3o Jo\u00e3o Hospital Centre, Porto, Portugal"}]},{"given":"Rosa","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Neurology, S\u00e3o Jo\u00e3o Hospital Centre, Porto, Portugal"}]},{"given":"Elsa","family":"Azevedo","sequence":"additional","affiliation":[{"name":"Department of Neurology, S\u00e3o Jo\u00e3o Hospital Centre, Porto, Portugal"},{"name":"Faculty of Medicine of University of Porto, Porto, Portugal"}]}],"member":"239","published-online":{"date-parts":[[2018,6,6]]},"reference":[{"doi-asserted-by":"publisher","key":"2025090411345802000_18.5.378.1","DOI":"10.1002\/ana.21384"},{"doi-asserted-by":"publisher","key":"2025090411345802000_18.5.378.2","DOI":"10.1212\/01.wnl.0000223648.76430.27"},{"doi-asserted-by":"crossref","unstructured":"Grenon M , Sidhu RS .
