- Abstract
- BACKGROUND
Previous randomized controlled trials and meta-analyses comparing carotid endarterectomy (CEA) and carotid artery stenting (CAS) included a large number of patients, but the diagnosis, treatment selection, and performance were heterogeneous. This retrospective study from a single center in South Korea aimed to evaluate outcomes following CEA and CAS in patients with carotid artery stenosis.
MATERIAL AND METHODS
A retrospective analysis was performed using the data of patients who underwent carotid revascularization between September 2016 and June 2021 at a single institution. The primary outcomes were stroke, myocardial infarction (MI), and death during the periprocedural period.
RESULTS
We enrolled a total of 61 (44 symptomatic and 17 asymptomatic) patients who underwent CEA or CAS. Among them, 36 (59%) underwent CEA and 25 (41%) underwent CAS. Statistically significant differences were found between the groups in degree of carotid stenosis (CEA: 87.0±9.1, CAS: 80.5±9.3, P=0.007). All patients with confirmed plaque ulceration before carotid revascularization underwent CEA. Two (3.3%) periprocedural strokes occurred, 1 in each group, on the ipsilateral side. There were no significant differences between CEA and CAS in the event-free survival rate for stroke during the follow-up (log-rank test=0.806).
CONCLUSIONS
Favorable outcomes in terms of periprocedural stroke were observed. We found no significant difference between the 2 carotid revascularization techniques in the incidence of periprocedural stroke in symptomatic and asymptomatic patients. To confirm our findings, further studies involving a larger number of patients and continuous follow-up are necessary.
