INTRODUCTION: We reviewed our experience of carotid artery stenting (CAS) in patients older than 75 years treated
with open or closed cell stents. The aim of our paper is to evaluate if there are differences between the two groups in
term of clinical outcomes, neurological impairment and survival.
MATERIAL AND METHODS: CAS consecutively performed from March 2000 and December 2016 in elderly patients were rectrospectively collected. We classified them into two groups: closed cells (group A) and open cells stent (group B).Perioperative and long term events were observed (death, major cerebrovascular and cardiovascular events, in-stent restenosis).
RESULTS: We collected 429 CAS, 259 (60.37%) male with median age of 79 years (range 77-82). Group A collects
247 (57.98%) patients, 142 (33.3%) in group B. The other 40 patients were treated with hybrid stents or just ballooning.
In perioperative period we had not death but 2 patients (0.8%) in group A had a transient ischemic attack
(TIA) due to immediate stent thrombosis, 2 patients (1 per group) had an ipsilateral major stroke and 8 patients had
a TIA (3 in group A and 5 in group B). Median follow up was 686 days (IQR 267-1299 days). Freedom from complications
at 12, 36 and 60 months was 99.4 ± 0.5%, 97 ± 1.5% and 90.08 ± 4.3% respectively. Survival at 12,
36 and 60 months was 77.4 ± 7.5%, 51.6 ± 8.9% and 16.1± 6.6% respectively.
CONCLUSION: Our data show CAS as a safe procedure also for people older than 75 years in terms of perioperative and
long term complications and cerebral events without any significant difference between the different type of stent. Further
studies are requested to better clarify its role in symptomatic patients.
