Carotid artery stenting: a single-center experience

Abstract

Aim: This study aimed to present the results of carotid artery stenting (CAS) in the treatment of patients with symptomatic and asymptomatic carotid artery stenosis (Cs).
 Material and Method: Between September 2016 and June 2021, patients who underwent CAS in the interventional radiology department were reviewed, retrospectively. The demographic data of patients, comorbidities, carotid stenosis rates, and early and late complication rates after treatment were recorded from medical records. Acute stent thrombosis, stroke, and death in the first 30 days after CAS were considered early periprocedural complications. Doppler ultrasonography (USG) examinations were scanned at 6 months after the procedure and restenosis rates were investigated.
 Results: There were a total of 113 patients; 31.2% female and 68.8% male. Symptomatic Cs was present in 62.8% (n=71) and asymptomatic Cs in 37.2% (n=42) of the patients. The technical success rate was determined as 98.2%. Micro-thromboembolism (n=4), pseudoaneurysm at the femoral insertion site (n=2), and acute stent thrombosis (n=1) were observed as early complications. Restenosis was detected 6 months after stenting in 1 patient (1.4%) with symptomatic Cs on Doppler USG. The mortality rate was 0.8% (n=1). 
 Conclusion: CAS is an effective and safe treatment method in symptomatic and asymptomatic patients with Cs.
