Purpose: To determine the safety of carotid artery stenting (CAS) using an emboli-protection device in elderly patients with severe carotid artery stenosis.
Materials and Methods : Ninety consecutive patients who were at high risk for carotid endarterectomy underwent protected CAS using an emboli-protection device. Patients were divided into two groups by age: < 70 and ≥ 70. The primary outcome measure was the combined incidence of stroke, myocardial infarction (MI), and death within 30 days of CAS. The secondary outcome measures were technical success and hyperperfusion syndrome. Associations between age and the clinical outcomes were investigated.
Results: Overall, 30-day stroke, MI, and death rates were 6.7%. There was no significant difference in the primary outcome between the older age group (n = 56) and younger age group (n = 34) (8.9% and 2.9%, respectively; HR for age ≥ 70, 1.141; 95% CI, 0.875 to 1.488, p = 0.331). A logistic regression showed there was no independent variable associated with primary outcome. Technical success was achieved in all patients and there was no significant difference in the incidence of hyperperfusion syndrome between the two age groups.
Conclusion: The results of this study suggest that protected CAS seems to be safe in elderly patients with severe carotid artery stenosis.
