Aridi HD, et al. - This study aims to analyze the rates, reasons, and risk factors of 30-day readmission, both planned and unplanned, after carotid revascularization as well as to evaluate major outcomes associated with those readmissions. Observations reveal lower 30-day readmission rates with carotid artery stenting (CAS) in comparison with carotid endarterectomy (CEA). However, CAS readmissions are more complex and are associated with higher mortality and costs. Patients who are at high risk of readmissions are also identified, which can help focus attention on interventions that can improve the management of these patients and reduce readmission rates.
