The aim - to assess the carotid artery angioplasty and stenting early and late results and influencing factors. Methods. The study assessed CAS procedures performed in 2006-2013. A total of 227 procedures performed in 211 patients, of which 156 (75.3%) males and 55 (24.7%) females. Results. The study revealed that CAS procedure duration among patient with 3 aortic arch type was significantly longer and the microemboli protection systems were used more frequently. Protection systems were used more frequently when the CAS procedure lasted longer. Protection systems in CAS procedure was used in 70.9% patients. In men and younger patients protection system has been used more frequently. Microemboli in the protection systems have been identified by 17.6% patients and were more determined using the EZ FilterWire and Emboshield-NAV protection system. Increased right ICA stenosis was more common in patients who smoke, and left ICA with a history of myocardial infarction and smoking. Protection system was often used in patients who have had severe left ICA stenosis. The lethality rate in the early post procedural period among men and women was 1.2% and 1.8%, and in 2-year period was 18.7% and 28.6%, respectively. The lethality rate during 2-year period, which have been used for protective systems have been lower. The possibility to experience complications (stroke or TIA) increased 3 aortic arch type and the right common carotid artery stenosis, reduced protection systems using. Focal, linear, Ipsi- and bilateral ischemic cerebral injury was diagnosed less frequently in patients who have undergone Emboshield-NAV type of protection. During 1 year after the CAS cognitive and motor functions worsening, but no significant improvement was obtained. Before CAS poorer cognitive function compared with the control group, was established in symptomatic patients. Both symptomatic and asymptomatic patients before the CAS significantly lower by motor tasks as compared with the control subjects. |
