Contralateral Occlusion Increases the Risk of Neurological Complications Associated with Carotid Endarterectomy

Table 3

Multivariate analysis of the role side of brain infarct related to the operated carotid artery on perioperative neurological outcome (stroke and stroke-related mortality) in 1639 primary carotid revascularizations (overall population brain lesion analysis OR 0.86, 95% CI 0.42–1.77, = 0.69).
