The aim of this observational study was to analyze the early and late outcomes of CEA in patients with a carotid tandem lesion (CTL), defined as a severe stenosis at the bifurcation with any concomitant lesion \u226550 % involving the intracranial portion of the ipsilateral internal carotid artery or the main trunk of the anterior or middle cerebral artery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From 2000 to 2009, 1143 patients underwent CEA for symptomatic or asymptomatic extracranial carotid stenosis according to the NASCET and ACAS recommendations, respectively. CTLs were diagnosed in 219 patients (19.2 %) by extracranial and transcranial color\u2010coded Doppler sonography combined with noninvasive brain imaging studies. The primary endpoints of the study were perioperative (30\u2010day) stroke and death, and any ipsilateral ischemic adverse events during the follow\u2010up, which ranged from 0.1 to 10 years (mean 4.9 \u00b1 3.3 years).

There were 2 (0.9 %) perioperative ipsilateral strokes in group I and 5 (0.5 %) in group II (<jats:italic>p<\/jats:italic> = 0.62), and no deaths.
