Background/Objectives: Dual-layer stents (DLS) with micromesh technology may offer better protection from plaque protrusion compared to single-layer stents (SLS), but little data are available. The aim of this study is to compare clinical outcomes of elective carotid artery stenting for asymptomatic and symptomatic patients treated for primary CAS with DLS or SLS in a high-volume center. Methods: This study is a single-center retrospective cohort study and included patients who underwent elective CAS between December 2006 and September 2023. The final analysis included patient baseline characteristics, postoperative complications and patient outcomes. Results: A total of 573 patients underwent elective carotid artery stenting in the study period. Most of the 573 patients undergoing CAS were male (62.5%), and the median age of patients at the time of CAS was 70 years. Of the 573 eligible patients, 43.5% (n = 249) were asymptomatic and 56.4% (n = 323) were symptomatic. Analyzing neurological complications, it was found that the only factor that had a statistically significant effect was the type of stent used. Patients who had a carotid stenting procedure using a single-layer carotid stent had statistically significantly more periprocedural neurological complications (8.3% (n = 35)) than the double-mesh stent group (2% (n = 3)), mostly due to more transient ischemic attacks in the single-layer stent group (4% (n = 17)) compared to the double-mesh group (0.7% (n = 1)). Conclusions: The use of carotid double-layer stents is associated with a low rate of periprocedural and postprocedural events.
