Özet

Objectives: Carotid artery stenting (CAS) and carotid endarterectomy are established treatments for carotid artery stenosis. We evaluated the early and mid-to late-term clinical and radiological outcomes of patients who underwent CAS. Materials and Methods: This retrospective study included 98 patients (112 arteries), who underwent CAS. Baseline demographics, stent types, embolic protection devices, and procedural complication rates within 30-day and 3-year post-CAS, including transient ischemic attack (TIA), stroke, death, and stent restenosis, were analyzed. Results: The 30-day complication rates included TIA (5.1%), ipsilateral stroke (4.1%), and death (4.1%). At three-year follow-up, TIA (8.5%), ipsilateral stroke (2.1%), restenosis (1.1%), and death (6.4%) were observed. Contralateral carotid artery angiography revealed neointimal hyperplasia in two vessels (1.9%) and 70–99% restenosis 1 (1%). Notably, a significant association was observed between neointimal hyperplasia and stent geometry, with a higher incidence observed in open-cell stents compared to closed-cell stents (P = 0.03). Conclusion: Our study demonstrated comparable early-term and lower mid-to late-term complication rates compared to prior studies. A multidisciplinary approach with meticulous technique, appropriate materials, and careful patient selection can optimize CAS outcomes.
