Key result
Carotid artery stenting without embolic protection devices resulted in acute cerebral microemboli in 5.66% of patients and mild clinical deterioration in 7.5%.
Why the study?
There is debate regarding the efficacy and complications of carotid artery stenting without embolic protection devices for carotid artery stenosis.
Observational (n=53)
Yes
Carotid artery stenting without embolic protection devices demonstrated a low rate of clinical and radiological microembolic complications at 30 days.
Suggests acceptable safety of unprotected carotid stenting; leaves open comparative efficacy versus embolic protection devices.
Background: There is debate about the efficacy and complications of The utilisation of carotid artery stenting in the management of carotid artery stenosis, in the absence of embolic protective devices. Objective: To estimate the incidence of microembolic events in CAS procedures without protection device. Patients and Methods: Fifty-three patients with carotid artery stenosis who attended The Neurology Clinic of Kobri El-Koba Military and Al-Hussien University Hospitals, Egypt from July 2022 to March 2023. Undergoing carotid artery stenting without protection devices. Outcome was assessed clinically with the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) and radiologically with Diffusion-weighted magnetic resonance imaging (DWI-MRI) 24hrs before and after the procedure and follow up after 30 days. Results: There was a low complication rate as only four cases (7.547%) showed mild deterioration in NIHSS and three other cases (5.66%) showed that novel instances of acute cerebral microemboli were identified through the use of brain diffusion-weighted magnetic resonance imaging (DW-MRI), without any accompanying clinical deficits. Conclusion: Carotid artery stenting without the use of embolic protection devices can be considered as a safe and reliable method in treating the carotid artery stenosis.

El-Gharieb et al. (2024) conducted an observational in Carotid artery stenosis (n=53). Carotid artery stenting without protection devices was evaluated on Incidence of microembolic events and clinical deficits. Carotid artery stenting without embolic protection devices resulted in acute cerebral microemboli in 5.66% of patients and mild clinical deterioration in 7.5%.
