Key result
Restenosis after CAS linked to ~498% greater risk of ipsilateral cerebral infarction.
Why the study?
The risk of stroke due to restenosis after carotid artery stenting and independent predictors of restenosis occurrence were not well established.
Does restenosis after carotid artery stenting increase the risk of ipsilateral cerebral infarction, and what are the predictors of restenosis?
Cohort (n=250)
No
Does restenosis after carotid artery stenting increase the risk of ipsilateral cerebral infarction, and what are the predictors of restenosis?
Hazard Ratio: 5.98 (95% CI 1.19–24.47)
Absolute Event Rate: 15.8% vs 2.6%
p-value: p=0.032
Restenosis after carotid artery stenting significantly increases the risk of ipsilateral stroke, and the use of closed cell stents is an independent predictor of such restenosis.

Miyata et al. (2015) conducted a cohort in Carotid artery stenting (n=250). Restenosis vs. No restenosis was evaluated on Ipsilateral cerebral infarction (HR 5.98, 95% CI 1.19-24.47, p=0.032). Restenosis after carotid artery stenting significantly increased the risk of ipsilateral cerebral infarction (HR 5.98; 95% CI 1.19-24.47; p=0.032).
