The article describes the experience of carotid stenting use in asymptomatic cerebral atherosclerosis. The study included 147 patients with unilateral asymptomatic carotid artery disease. The evaluation of mid-longterm results of carotid stenting in patients with asymptomatic stenosis was carried out in comparison with the use of conservative treatment in this category of patients (“optimal drug treatment”). In the course of the work, no significant intergroup difference was revealed in the incidence of adverse outcomes (TIA/stroke, death from stroke,) within a year from the moment of surgical treatment or the beginning of complex correction of risk factors.

Background & Objective Considering an increasing incidence of carotid artery disease in Asian subjects, the data showing long-term outcome of carotid artery stenting(CAS) from Asian population is mandatory. However, long-term outcome of CAS in Asian population have rarely been reported. The purpose of this study is to evaluate long-term results of CAS from the 10-year experience of a single center. Methods Patients undergoing CAS between May 2002 and May 2012 in our hospital were retrospectively reviewed. We abstracted demographic, clinical, and medical factors. In addition, plaque characteristics and angiographic factors were also evaluated. Neck CT angiography was followed-up every 6 months after CAS. We investigated the cumulative long-term incidence of carotid restenosis and risk factors for the development of restenosis. Results A total of 262 arteries (248 patients, mean age of 72.1±7.6 years, 81.7% male) were analysed. The degree of mean carotid stenosis was 70.9±17.5%. Symptomatic lesions were 178 (67.9%), and 84 (32.1%) arteries were asymptomatic. Predilatation (97.3%) and post-dilatation (42.4%) was performed during procedures. Embolic protection devices were used in 233 (88.9%) cases. During procedures, In-situ thrombosis with embolic infarction or TIA occurred in 6 (2.3%) and 10 (3.8%) cases, respectively. During a median follow-up time of 27.5 months, restenosis (> 50% stenosis) was detected in 18 (6.9%) of 262 arteries (asymptomatic, 16; symptomatic, 2). Restenotic lesions were treated in 6 (2.3%) cases with angioplasty including 2 symptomatic patients. The percentage of residual stenosis after stenting was significantly related to a risk of restenosis (p<0.02). Discussion Restenosis rate in this study was comparable to those of other single or multi-center trials in Western population. Our long-term results may validate CAS as a durable procedure for stroke prevention in patients with carotid artery stenosis in Korea.

The issue of strengthening the damaged linear reinforced concrete elements have been engaged since 2008. We focused on the analysis of resistance and the characteristics of limit states of serviceability in the damaged and subsequently strengthened elements at a short-term loading. In the introduction phase, the strengthening of the elements was carried out with the following procedures – installation of an overlayer on the coupling board or a combination of the board and use of glass – fiber fabric (GFRP). The strengthening was also affected by the type of contact (reinforced/non-reinforced) – the deformed element/coupling board and its effect on resistance, type of deformation and serviceability. In the non-reinforced contact, we applied some of the types of adjustments to the surface of the strengthened element. At the moment, we are dealing with the effects of time and repeated load on the strengthened elements. The results correspond to the reinforced contact. The values are compared with the short-term results of the strengthened beams and with the long-term results of the beams prepared for strengthening.

Graft Interposition

Procedures used in treatment of carotid stenosis are endarterectomy, PTA with stent implantation, resection with graft interposition and by-pass procedure. Segmental lesions are found more often and treated by the first two mentioned procedures. In case of longer lesions and extension to the greater part of the common carotid artery, the other two procedures are performed. For the past few years, the main dilemma has been whether to perform carotid endarterectomy or PTA with stent implantation. Both early and long-term results speak in favour of carotid endarterectomy, regardless of an increased number of PTA and carotid stenting. At the same time, PTA and carotid stenting are more expensive procedures. Both methods have their defined and important roles in treatment of segmental occlusive carotid lesions. Severe cardiac, pulmonary and renal conditions, which increase the risk of general anaesthesia, are not an absolute indication for PTA and stenting, since endarterectomy can be done in regional anaesthesia. Main indications for PTA with stent implantation are: surgically inaccessible lesions (at or above C2; or subclavian); radiation- induced carotid stenosis; prior ipsilateral radical neck dissection; prior carotid endarterectomy (restenosis).

Objective. Due to the different stroke risk exposure, advisability of carotid revascularization by carotid stenting (CAS) or endarterectomy (CEA) strictly depends on patients’ symptomatic status. Periprocedural and 5-year data of 2196 consecutive procedures (1080 CAS, 1116 CEA) based on physician-guided indication for CEA vs CAS and performed after training outside randomized trials, were reviewed for safety. Methods. 684 symptomatic and 1512 asymptomatic patients were analyzed for periprocedural stroke/death and 5-year death or stroke incidence. Kaplan-Meier survival curves with type-of-procedure interaction were employed. Results. Symptomatic patients were older (71.9y vs 71.04y), less frequently females (25.3% vs 30.8%) and treated more by CEA (60.8%) than by CAS (p<0.001). Asymptomatic patients were more likely affected by cardiac disease, peripheral disease and hyperlipidemia. Periprocedural stroke/death was higher in symptomatic than in asymptomatic patients (3.5% vs 1.9%;OR 1.8, 95%CI1.07-3.2) without significant differences between CAS and CEA in both symptomatic (4.5%CAS vs 2.9%CEA) and asymptomatic (2.2% CAS vs 1.6% CEA) groups. Symptomatic patients showed higher 5-year mortality and stroke incidence: survival rate was 78.4% in symptomatic and 85.5% in asymptomatic (p<0.0001). Late stroke freedom was 93.5% in symptomatic and 97.7% in asymptomatic (p=0.001). There were no differences, according to the procedure (CAS vs CEA) for treatment, in survival (Symptomatic: 85% vs 75%; Asymptomatic: 83% vs 83%) or late stroke incidence (Symptomatic: 93% vs 93%; Asymptomatic: 97% vs 97%). Conclusions. Symptomatic patients show higher risks after carotid revascularization and 5-year outcomes are inferior to those of asymptomatic patients regardless of the surgical procedure. Periprocedural stroke/death rates, either by CAS or CEA, are within the complication threshold rates suggested in current guidelines for both symptomatic and asymptomatic patients.
