Objectives: Octogenarians account for a third of ischemic stroke (IS) patients and applying endovascular carotid artery stenting (CAS), as a secondary prevention, in these patients is challenging. The aim of this study was to evaluate peri-procedural and long term clinical and angiographic impact of CAS on octogenarians., Patients and Methods: In a prospective study, 102 patients aged over 80 years old with symptomatic internal carotid artery (ICA) stenosis presenting by non-disabling IS or transient ischemic attack and having undergone CAS were evaluated prospectively from January 2012 to July 2016. All patients received standard stroke care during the study follow up period. Peri-procedural complication, cerebrovascular accidents, restenosis in target vessel and mortality rate were recorded and the collected data were analyzed to evaluate safety and durability of CAS in octogenarians., Results: 48 (47.06%) males and 54 (52.9%) females with the mean age of 83.39 ± 2.53 (range, 80-88) years were followed in a mean period of 24.5 ± 14.1 months (6-50 months). Success rate of CAS was 100%; whereas, the peri-procedural complication rate was 5.8% (only one patient experienced acute ischemic stroke during the procedure). Restenosis and recurrent cerebrovascular accidents were observed in 3.9% and 9.8% of the cases, respectively. Recurrent cerebrovascular accident leading to death was seen in 2.9% of the cases. The median patient event-free survival was 20 months., Conclusion: Endovascular CAS seems to be a safe and durable method for secondary prevention in ischemic stroke following symptomatic carotid artery stenosis in octogenarians., (Copyright © 2018 Elsevier B.V.
