Unprotected carotid stenting links to a ~5% 30-day stroke or death rate in symptomatic patients.
Cohort (n=302)
Answers are grounded in this paper and cite their sources.
Patients with symptomatic > or = 60% (n = 134), asymptomatic > or = 80% (n = 143), and asymptomatic progressive > or = 60% (n = 25) internal carotid artery stenosis underwent stenting and were followed clinically and by Doppler-assisted duplex imaging for 27.1 +/- 15.6 months. Stroke and death from stroke occurred within 30 days after stenting in 4.7% of the symptomatic and in 3.0% of the asymptomatic patients and in the follow-up period in 2.3% of the symptomatic and in 1.2% of the asymptomatic patients.

Bibl et al. (2005) conducted a cohort in Internal carotid artery stenosis (n=302). Internal carotid artery stent placement without emboli protection was evaluated on Stroke and death from stroke within 30 days and during follow-up. Internal carotid artery stenting without emboli protection was associated with a 30-day stroke and stroke-death rate of 4.7% in symptomatic and 3.0% in asymptomatic patients.
