Influence of the type of cerebral infarct and timing of intervention in the early outcomes after carotid endarterectomy for symptomatic stenosis

{Objective: Our objectives were to compare early postoperative outcomes after carotid endarterectomy for symptomatic carotid stenosis and to analyze the impact of time to treatment between patients with a territorial or a border-zone infarct. Methods: This is a single-center, retrospective study carried out on data from a single-center, prospective database. Patients undergoing carotid endarterectomy for symptomatic carotid stenosis after an ipsilateral acute ischemic stroke were included between January 1, 2009 and December 31, 2013. The only exclusion criterion was a mixed-topography stroke. We included 114 patients who were retrospectively divided into groups according to the location of the infarct: group TI for territorial infarction and group BZ for border-zone infarction. The primary end point was the 30-day death or stroke rate. Results: Ninety patients were included in the TI group (79%) and 24 in the BZ group (21%) with a mean age of 73 +/- 6 11 years. All demographic data were similar between the two groups except for dyslipidemia, which was greater in the BZ group (72% vs 47%
