Steno-occlusive disease of the carotid arteries is a consequence of a generalized atherosclerotic process in the human body. Approximately 20% of all strokes are caused by carotid artery stenosis. Since stroke is the third leading cause of death and the first leading cause of disability in the world, the importance of its successful treatment is evident. At our Centre, we conducted a retrospective study on 120 patients who, over the course of two years, underwent stenting of the internal carotid artery due to symptomatic stenosis or asymptomatic, but hemodynamically significant high-grade stenosis. The follow-up period was a minimum of 12 months after the procedure. The aim of our study was to determine the frequency of occurrence of early and late complications of stenting. Early complications, within the first 24 hours, were related to the procedure itself and amounted to 3.3%. As for late complications of the procedure, the followup was 3, 6 and 12 months after the procedure and the patients were evaluated clinically and neurosonologically each time. We monitored the occurrence of clinical complications such as transient ischemic attack and/or stroke, and with ultrasound we determined the patency of the stent, i.e., the possible progression of restenosis in the postoperative period. There were also 3,3% of clinical complications, exclusively in the first three months after the stent implantation. All clinical complications were in the form of transient ischemic attacks. Progression of stenosis on ultrasound findings was found in up to 11% of patients, but none of these patients showed any clinical symptoms of the disease as a result of stenosis progression. Overall, our study showed very low rates of both early and late complications. We compared our results with data from the literature and saw that our results correspond to the reported frequency of stenting complications. We compared our results with percentages of complications after thrombendarterectomy, where we did not notice a significant difference in the occurrence of complications as well. All of the above speaks in favour of the success of the analysed method of treatment of the carotid artery steno-occlusive changes. In choosing the method of treatment for carotid stenosis, the most important limiting factor is the experience in performing the procedure of stent implantation of the centre that performs the treatment. In a centre with long and rich experience, endovascular treatment of carotid artery stenosis with stent implantation is a safe and very successful method of treatment.
