摘要
Purpose: The study investigated the association between cell-stent area and cerebrovascular events incidence in asymptomatic patients undergoing carotid artery stenting (CAS).Materials and Methods: This is an observational, retrospective, multicenter, cohort study. Between 2012 and 2022, all patients undergoing primary CAS for severe asymptomatic carotid artery stenosis were evaluated. Three groups were defined on the basis of the cell area (open cell, OC; closed cell, CC; double layer, DL). Periprocedural primary outcomes were 30-day stroke, mortality, myocardial infarction (MI), and major adverse event (MAE, stroke/mortality composite outcome) rates. Follow-up primary outcomes included overall survival, stroke-free survival (SFS), freedom from ipsilateral stroke (FFiS), and freedom from stroke-related mortality (FF-SRM). Data were analyzed at short-term (1 year) and mid-term (2.5 years) period.Results: A total of 1096 CAS were considered (787 men, 71.8%, median age = 74 years). Technical success was achieved in 99.5% procedures. Periprocedural 30-day stroke rate was 1.5% (OC: 1.1%, CC: 2.3%, DL: 1%, p=0.27), mortality was 0.7% (OC: 1.1%, CC: 0.3%, DL: 0.5%, p=0.35), and no MI was recorded. The MAE rate was 2.1% (OC: 2%, CC: 2.6%, DL: 1.5%, p=0.66). Median follow-up was 46 months. At 1 and 2.5 years, estimated overall survival was 96.1% and 91% (p=0.41), SFS was 99.1% and 98.2% (p=0.007, CC stroke rates 2.9% and 4.2% at timepoints), FFiS was 99.4% and 99% (p=0.014, CC FFiS rates 1.7% and 2.6% at timepoints) and FF-SRM was 99.5% and 99% (p=0.28). During follow-up, no stroke events occurred in DL group. CC design showed higher rates of any (4.2%) and ipsilateral stroke (2.6%) within 2.5 years.Conclusion: In asymptomatic patients undergoing CAS, the contemporary overall stroke incidence is 1.5%. No statistical differences were observed in terms of 30-day stroke incidence among groups. The closed free-cell area showed higher rates of any and ipsilateral stroke within 2.5 years. The DL stents may offer the best available performances in terms of mid-term stroke prevention.Clinical Impact The study analyzed the contemporary results of carotid artery stenting (CAS) focusing on the impact of cell-stent area on peri- and post-operative cerebrovascular events in a multicenter real-world experience. In asymptomatic patients undergoing CAS the contemporary overall stroke incidence is 1.5%. No statistical differences were observed in terms of 30-day stroke incidence among groups. The closed free-cell area showed higher rates of any and ipsilateral stroke within 2.5 years. DL stents may offer the best available performances in terms of mid-term stroke prevention.
