The use of embolic protection devices during carotid artery stenting reduced the mortality rate to 1% compared to 2% without protection, and also lowered the rates of major stroke and myocardial infarction.
Meta-Analysis (n=3,875)
Does the use of embolic protection devices reduce thromboembolic complications in patients undergoing carotid artery stenting?
The use of embolic protection devices during carotid artery stenting significantly reduces the risk of major stroke, myocardial infarction, and death compared to unprotected stenting.
Absolute Event Rate: 1% vs 2%
Background: This study compared the rate of thromboembolic events during carotid angioplasty and stenting (CAS) with and without embolic protection devices (EPDs). We reviewed literature to find studies comparing embolic event rates during CAS with and without EPDs and conducted a meta-analysis to determine the safer approach.Methods: The Embase, PubMed, and Web of Science databases were thoroughly searched following PRISMA guidelines. Each estimation was executed using random-effects models. The I2 index was used to assess the heterogeneity among the studies. Egger and Begg’s tests were applied to evaluate publication bias. Stata version 14.2 was used for statistical analysis.Results: For 25% of patients, an EPD was used during CAS, and for 75% it was not. Of the patients undergoing CAS, the prevalences of hypertension, diabetes mellitus, coronary artery disease, and cigarette smoking were 81%, 37%, 39% and 43%, respectively. In total, of the patients included 52% were symptomatic and 48% were asymptomatic. The mortality rate reduced from 2% in the no-EPD subgroup to 1% in the EPD subgroup. The occurrence of all other complications was also reportedly higher in patients who did not receive an EPD, including major stroke and myocardial infarction, except for minor events, which were reported to be almost the same in both subgroups.Conclusions: We found that the use of an EPD can help reduce the occurrence of thromboembolic complications of CAS, including myocardial infarction, major stroke, and death. Altogether, our results suggest that the benefits of using an EPD during CAS outweigh its risks.
Sadr et al. (Fri,) conducted a meta-analysis in Carotid artery stenosis (n=3,875). Embolic protection devices vs. Carotid angioplasty and stenting without embolic protection devices was evaluated on Mortality. The use of embolic protection devices during carotid artery stenting reduced the mortality rate to 1% compared to 2% without protection, and also lowered the rates of major stroke and myocardial infarction.
