Key Points Question Is carotid artery stenting (CAS) during mechanical thrombectomy (MT) associated with improved functional outcome without an increase in hemorrhagic rates in patients with large vessel occlusion ischemic stroke with tandem lesions, defined as concomitant large vessel occlusion and stenosis or occlusion of the cervical internal carotid artery? Findings In this cross-sectional study of 685 patients with tandem lesions, compared with nonstenting, CAS of the cervical lesion during MT was associated with increased odds of achieving a modified Rankin Scale score of 0 to 2, whereas the rates of symptomatic intracranial hemorrhage were similar at 90 days. Meaning These findings suggest that CAS of the cervical lesion during MT may represent an appropriate endovascular approach for patients with tandem lesions.
