Abstract :Objective: This study aimed to examine complications that may occur after carotid artery stenting insert ignore into journalissuearticles values(CAS); and their relationships with carotid artery stenosis rate. Materials and Methods: Complications, such as cerebral hyperperfusion, stroke, death, stent thrombosis or occlusion and restenosis, were evaluated on the 30th day after CAS and at the end of the first year. Results: Of the 205 CAS procedures, complications developed in 12 patients. The complication rate for the first 30 days after the procedure was 4,87%, and at the end of the first year, it was 5,85%. Of the 12 patients with complications, 8 had carotid stenosis of ≥90%. Death occurred in 4 of 195 patients with carotid artery stenosis. The mortality rate within the first 30 days and during the 1-year follow-up period was 1,53% and 2,05%, respectively. Ischemic stroke occurred in 6 of 195 patients with carotid artery stenosis. After the first 30 days and one year follow-up, ischemic stroke had occurred in 3,07% of patients. Stent thrombosis and occlusion rate was 4,87% in 205 CAS procedures, and 7 of them occurred in the first 24 hours and another 3 occurred within the first 30 days. Restenosis rates were 0,48% and 0,97% at 6 months and the first year, respectively. Conclusion: The complications of CAS have been associated with the urgency of treatment insert ignore into journalissuearticles values(emergency);, symptom presence insert ignore into journalissuearticles values(symptomatic patients); and high degree of stenosis insert ignore into journalissuearticles values(≥90%);; whereas bilateral stenosis is not associated with complications. In addition, stent thrombosis and occlusion were observed as the most common CAS complication.
