New Ischemic Cerebral Lesions in Postprocedural Magnetic Resonance Imaging in Carotid Artery Stenting Versus Carotid Endarterectomy: A Systematic Review and Meta-Analysis. Ann Vasc Surg 2024; 106:297-311. [PMID: 38825067 DOI: 10.1016/j.avsg.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 05/12/2024] [Accepted: 05/15/2024] [Indexed: 06/04/2024]
Abstract
BACKGROUND Recent randomized controlled trials (RCTs) have demonstrated similar outcomes in terms of ischemic stroke incidence after carotid endarterectomy (CEA) or carotid artery stenting (CAS) in asymptomatic carotid disease, while CEA seems to be the first option for symptomatic carotid disease. The aim of this meta-analysis is to assess the incidence of silent cerebral microembolization detected by magnetic resonance imaging (MRI) following these procedures. METHODS A systematic search was conducted using PubMed, Scopus, and Cochrane databases, including comparative studies involving symptomatic or asymptomatic patients undergoing either CEA or CAS and reporting on new cerebral ischemic lesions in postoperative MRI. The primary outcome was the newly detected cerebral ischemic lesions. Pooled effect estimates for all outcomes were calculated using the random-effects model. Prespecified random effects metaregression and subgroup analysis were conducted to examine the impact of moderator variables on the presence of new cerebral ischemic lesions. RESULTS 25 studies reporting on a total of 1827 CEA and 1500 CAS interventions fulfilled the eligibility criteria. The incidence of new cerebral ischemic lesions was significantly lower after CEA compared to CAS, regardless of the time of MRI assessment (first 24 hours; OR: 0.33, 95% CI: 0.17-0.64, P < 0.001), (the first 72 hours, OR: 0.25, 95% CI 0.18-0.36, P < 0.001), (generally within a week after the operation; OR: 0.24, 95% CI: 0.17-0.34, P < 0.001). Also, the rate of stroke (OR: 0.38, 95% CI: 0.23-0.63, P < 0.001) and the presence of contralateral new cerebral ischemic lesions (OR: 0.16, 95% CI 0.08-0.32, P < 0.001) were less frequent after CEA. Subgroup analysis based on the study design and the use of embolic protection device during CAS showed consistently lower rates of new lesions after CEA. CONCLUSIONS CEA demonstrates significant lower rates of new silent cerebral microembolization, as detected by MRI in postoperative period compared with CAS.

Abstract
BACKGROUND This study aims to assess the role and safety of post-dilatation in protected carotid artery stenting (PCAS) using the new MicroNet-covered 2nd-generation stent assessed by cone beam CT scans. METHODS From March 2020 to March 2022, patients were enrolled in the study according to CT angiography results based on the following criteria: Evidence of 70% to 99% carotid stenosis in asymptomatic patients and 50% to 99% in symptomatic patients, per the NASCET index. Using a FilterWire EZ™ (Boston Scientific, Natick, MA, USA) embolic protection system (EPS), MicroNet-covered stent PCAS was performed by two interventional radiologists with at least 8 years of experience in endovascular intervention. Each patient underwent post-dilatation following stent placement. Finally, a third radiologist (not participating in the interventional procedures) evaluated the cone beam CT scans and calculated residual stenosis. Major and minor complications were recorded in the 30 days following the procedure. RESULTS A total of 192 patients (121 male, mean age 73±10 years) were included in the study, and all patients received post-dilatation following stent implantation. Technical successes were achieved in all procedures. Adverse events noted in this study were limited to periprocedural transient ischemic attacks that occurred in three out of 192 patients (1.6%) and showed a swift complete recovery. The post-dilatation balloon diameters used in the study were: 5.0 mm (30.3%), 5.5 mm (39.3%) and 6 mm (30.3%). Optimized postdilatation resulted in a significant increase in the final luminal area. Similar improvements were observed in all subtypes of plaque. CONCLUSIONS Post-dilatation in protected CAS is safe and induces a significant improvement in the cross-sectional area regardless of the stenotic plaque.

Abstract
BACKGROUND Transcervical carotid artery revascularization (TCAR) has demonstrated a low overall stroke rate in carotid artery stenting (CAS). Furthermore, the use of a double-layer micromesh stent is expected to reduce embolization and plaque prolapse. The combination of TCAR and the double layer stent may lead to improved results compared to previously reported outcomes. The objective of this study is to present the findings of a prospective study including patients treated with the Roadsaver stent and TCAR. METHODS Between January 2017 and May 2022, 85 patients were enrolled. Every patient underwent TCAR with the Roadsaver stent. As per our protocol, a neurological examination and an ultrasound were performed within 24 hours before and after the procedure, and again 30 days after. A diffusion-weighted magnetic resonance imaging (DW-MRI) was conducted 24 hours before the procedure and 48-72 hours after the procedure. The primary endpoint was the detection of new ischemic lesions on postoperative DW-MRI. The secondary endpoint was a composite of all strokes, death, and myocardial infarction within 30 days. RESULTS Sixty-four patients (75.29%) were symptomatic, out of which 25 were treated within 14 days of the onset of the symptoms. Pre and postprocedural DW-MRI were performed in 83 patients. Postprocedural lesions were found in nine patients (10.84%). There were no strokes or death within 30 days, but two patients experienced a myocardial infarction. CONCLUSIONS Our study suggests that the use of TCAR and the Roadsaver stent could be a safe alternative to carotid endarterectomy because it entails a low incidence of cerebral embolization, even in recently symptomatic and elderly patients.

Abstract
Dual layer mesh stents constitute a novel treatment option for patients who undergo carotid artery stenting (CAS). The aim of this prospective study is to report 12 month outcomes of patients who underwent CAS with CGuard (Inspire MD, Tel Aviv, Israel) microNET self-expanding stent with embolic protection system in a tertiary center from October 2018 to March 2022. Primary endpoints included in-stent restenosis >70% verified by ultrasound (DUS), ipsilateral transient ischemic attack (TIA), and stroke at 12 months. Secondary endpoints included cardiovascular-related mortality (stroke, myocardial infarction, heart failure) and all-cause mortality during follow-up. One hundred thirteen patients were included in the study (male 72.5%), symptomatic 47.8%. Median follow-up was 25 months (2-48). By 12 months, there was one in-stent occlusion that manifested as stroke (1/113, 0.8%) but no other forms of in-stent restenosis. Two patients experienced contralateral TIA (1.7%). CVRM was 3.5% (4 MI) and all-cause mortality was 6% at follow-up. This prospective study shows that CAS with CGuard MicroNET-covered stent is safe with minimal neurological adverse events at 12 months follow-up. Larger, and longer-term studies are necessary to define CGuard long-term safety and protection against carotid-related stroke.

Abstract
Current management of patients with carotid artery stenosis is based on well-established guidelines, including surgical procedures - carotid endarterectomy (CEA) and endovascular carotid artery stenting (CAS) - and optimal medical treatment alone. Outcomes in the postprocedural period after CAS and CEA are similar, suggesting strong clinical durability for both treatments. Recent advances, which include the emergence of novel endovascular treatment tools and techniques, combined with more recent randomised trial data shed new light on optimal patient selection and treatment in contemporary practice. Improved, modern technologies including enhanced embolic protection devices and dual-layered micromesh stents yield better outcomes and should result in further improvements in CAS. In centres of excellence, nowadays, the majority of patients with severe carotid artery stenosis can be successfully treated with either CEA or CAS.

Clinical Outcomes of Second- versus First-Generation Carotid Stents: A Systematic Review and Meta-Analysis. J Clin Med 2022; 11:jcm11164819.

Abstract
Background: Single-cohort studies suggest that second-generation stents (SGS; “mesh stents”) may improve carotid artery stenting (CAS) outcomes by limiting peri- and postprocedural cerebral embolism. SGS differ in the stent frame construction, mesh material, and design, as well as in mesh-to-frame position (inside/outside). Objectives: To compare clinical outcomes of SGS in relation to first-generation stents (FGSs; single-layer) in CAS. Methods: We performed a systematic review and meta-analysis of clinical studies with FGSs and SGS (PRISMA methodology, 3302 records). Endpoints were 30-day death, stroke, myocardial infarction (DSM), and 12-month ipsilateral stroke (IS) and restenosis (ISR). A random-effect model was applied. Results: Data of 68,422 patients from 112 eligible studies (68.2% men, 44.9% symptomatic) were meta-analyzed. Thirty-day DSM was 1.30% vs. 4.11% (p < 0.01, data for SGS vs. FGS). Among SGS, both Casper/Roadsaver and CGuard reduced 30-day DSM (by 2.78 and 3.03 absolute percent, p = 0.02 and p < 0.001), whereas the Gore stent was neutral. SGSs significantly improved outcomes compared with closed-cell FGS (30-day stroke 0.6% vs. 2.32%, p = 0.014; DSM 1.3% vs. 3.15%, p < 0.01). At 12 months, in relation to FGS, Casper/Roadsaver reduced IS (−3.25%, p < 0.05) but increased ISR (+3.19%, p = 0.04), CGuard showed a reduction in both IS and ISR (−3.13%, −3.63%; p = 0.01, p < 0.01), whereas the Gore stent was neutral. Conclusions: Pooled SGS use was associated with improved short- and long-term clinical results of CAS. Individual SGS types, however, differed significantly in their outcomes, indicating a lack of a “mesh stent” class effect. Findings from this meta-analysis may provide clinically relevant information in anticipation of large-scale randomized trials.

Abstract
BACKGROUND AND PURPOSE Carotid angioplasty and stenting (CAS) could be considered for preventing stroke in patients with carotid artery stenosis. This study aimed to determine the incidence and the risk factors of the early and mid-term complications associated with CAS. METHODS This is a retrospective cohort study conducted at Shiraz University of Medical Sciences from March 2011 to March 2019. Patients at high risk and standard risk for carotid endarterectomy were included. The primary composite outcome was defined as stroke, myocardial infarction (MI), and death in the first 30 days after CAS. All-cause mortality, vascular mortality, and stroke were investigated during mid-term follow-up. RESULTS A total of 579 patients (618 CAS) were recruited (mean age: 71.52 years). Overall, 394 (68.40%), 211 (36.63%), 179 (31.07%), and 96 (16.72%) patients had hypertension, dyslipidemia, diabetes mellitus, or were cigarette smokers, respectively. Primary composite outcomes were observed in 2.59% of patients (1.55% stroke, 0.69% MI, and 1.72% death). Atrial fibrillation was a predictor of primary composite outcome in multivariate logistic regression (p = .048). The presence of total occlusion in the contralateral carotid artery was significantly associated with the risk of stroke in univariate logistic regression (p = .041). The patients were followed for a period ranging from 1 to 83 months. The overall survival rate for all-cause mortality was 93.48% at 1 year, 77.24% at 5 years, and 52.92% at 8 years. All-cause mortality was significantly higher among patients with symptomatic carotid stenosis (p = .014). CONCLUSION CAS provides acceptable short-term and mid-term outcomes in a unique population of high- and standard-surgical-risk, symptomatic and asymptomatic, octogenarian, and nonoctogenarian patients.

Abstract
INTRODUCTION Carotid artery stenting (CAS) using conventional (single-layer) stents is associated with worse clinical outcomes in diabetes mellitus (DM) vs. non-DM patients: an effect driven largely by lesion-related adverse events. CAS outcomes with MicroNet-covered stents (MCS) in diabetic patients have not been evaluated. AIM To compare short- and long-term clinical outcomes and restenosis rate in DM vs. non-DM patients with carotid stenosis treated using MCS. MATERIALS AND METHODS In a prospective study in all-comer symptomatic and increased-stroke-risk asymptomatic carotid stenosis, 101 consecutive patients (age 51-86 years, 41% diabetics) underwent 106 MCS-CAS. Clinical outcomes and duplex ultrasound velocities were assessed periprocedurally and at 30 days/12 months. RESULTS Baseline characteristics of DM vs. non-DM patients were similar except for a higher prevalence of recent cerebral symptoms in DM. Type 1 and type 1+2 plaques were more prevalent in DM patients (26.7% vs. 9.8%, p = 0.02; 62.2% vs. 37.7%, p = 0.01). Proximal embolic protection was more prevalent in DM (60% vs. 36%; p = 0.015). 30-day clinical complications were limited to a single periprocedural minor stroke in DM (2.4% vs. 0%, p = 0.22). 12-month in-stent velocities and clinical outcomes were not different (death rate 4.8% vs. 3.3%; p = 0.69; no new strokes). Restenosis rate was not different (0% vs. 1.7%, p = 0.22). CONCLUSIONS MCS may offset the adverse impact of DM on periprocedural, 30-day, and 12-month clinical complications of CAS and minimize the risk of in-stent restenosis. In this increased-stroke-risk cohort, adverse event rate was low both in DM and non-DM. Further larger-scale clinical datasets including extended follow-ups are warranted.

JACC Cardiovasc Interv 2021; 14:2377-2387. [PMID: 34736737 DOI: 10.1016/j.jcin.2021.08.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 07/27/2021] [Accepted: 08/03/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES The aim of this study was to compare procedure-related ipsilateral cerebral embolism with a conventional (Acculink, Abbott Vascular) versus a MicroNet-covered (CGuard, InspireMD) stent in carotid artery stenting (CAS). BACKGROUND The MicroNet-covered stent may reduce periprocedural cerebral embolism in CAS, but level 1 evidence is lacking. METHODS A total of 100 consecutive patients were randomized 1:1 to filter-protected CAS using the Acculink or the CGuard device. The study was powered for its primary endpoint of at least 50% reduction in ipsilateral diffusion-weighted magnetic resonance imaging lesion average volume 48 hours postprocedure (blinded external core laboratory analysis). RESULTS The baseline characteristics of the study groups were similar. Eighty-two (total volume = 18,212 mm3) diffusion-weighted magnetic resonance imaging postprocedural cerebral lesions occurred in 26 Acculink-treated patients and 45 lesions (total volume = 3,930 mm3; 78.4% reduction) in 25 CGuard-treated patients. New cerebral lesion average volume was 171 mm3 vs 73 mm3 (P = 0.017) per affected patient and 222 mm3 vs 84 mm3 (P = 0.038) per lesion (Acculink vs CGuard). In lesion-affected patients, the average sum of lesion volumes was 701 mm3 vs 157 mm3 (P = 0.007). The Acculink significantly increased the risk for multiple (≥5) cerebral lesions (relative risk: 7.8; 95% CI: 1.3-14.9; P = 0.021). At 30 days, new permanent (fluid-attenuated inversion recovery) lesion prevalence was 3:1 (P < 0.001), with total permanent lesion volume 7,474 mm3 vs 574 mm3 (92.3% reduction with the CGuard). There were 6 vs 0 new ipsilateral lesions (P = 0.030) and 2 versus 0 strokes. CONCLUSIONS The MicroNet-covered stent significantly reduced periprocedural and abolished postprocedural cerebral embolism in relation to a conventional carotid stent. This is consistent with the MicroNet-covered stent's sustained embolism prevention, translating into cerebral protection not only during but also after CAS. The present findings may influence decision making in carotid revascularization. (The SIBERIA Trial [Acculink™ Versus CGuard™]; NCT03488199).

Abstract
Atherosclerotic stenosis of the internal carotid artery is an important cause of stroke. The aim of this guideline is to analyse the evidence pertaining to medical, surgical and endovascular treatment of patients with carotid stenosis. These guidelines were developed based on the ESO standard operating procedure and followed the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. The working group identified relevant questions, performed systematic reviews and meta-analyses of the literature, assessed the quality of the available evidence, and wrote recommendations. Based on moderate quality evidence, we recommend carotid endarterectomy (CEA) in patients with ≥60-99% asymptomatic carotid stenosis considered to be at increased risk of stroke on best medical treatment (BMT) alone. We also recommend CEA for patients with ≥70-99% symptomatic stenosis, and we suggest CEA for patients with 50-69% symptomatic stenosis. Based on high quality evidence, we recommend CEA should be performed early, ideally within two weeks of the last retinal or cerebral ischaemic event in patients with ≥50-99% symptomatic stenosis. Based on low quality evidence, carotid artery stenting (CAS) may be considered in patients < 70 years old with symptomatic ≥50-99% carotid stenosis. Several randomised trials supporting these recommendations were started decades ago, and BMT, CEA and CAS have evolved since. The results of another large trial comparing outcomes after CAS versus CEA in patients with asymptomatic stenosis are anticipated in the near future. Further trials are needed to reassess the benefits of carotid revascularisation in combination with modern BMT in subgroups of patients with carotid stenosis.

Abstract
OBJECTIVE The aim of this study was to provide early-term evaluation, safety, and efficacy of the novel CGuard (Inspire MD, Tel Aviv, Israel) micromesh self-expanding stent with embolic protection system (EPS) during carotid artery stenting (CAS) procedure. MATERIALS AND METHODS All patients who underwent CAS with CGuard carotid stent system from January 2018 to September 2020 in a tertiary center were prospectively evaluated. Primary endpoints included technical success and perioperative neurological events (0-48 hours). Secondary endpoint was the rate of neurologic, cardiac events, and death (major adverse event or MAE) at 30 days. Patency of CGuard, peak systolic velocity (PSV), and end diastolic velocity (EDV) were evaluated at 30 days with duplex ultrasound. RESULTS A total of 103 patients underwent CAS procedure. Forty patients were symptomatic, and 63 patients were asymptomatic with stenosis greater than 70%. Technical success was 100%. Local anesthesia was applied in 94 patients (93%). Embolic protection devices were used in 6 patients (5.8%). Access site complications were 1.9%. Mean internal carotid artery stenosis diameter reduced from 79.47% to 14.68%. Two patients had transient ischemic attack (1.9%) and 1 patient experienced a cerebral hyperperfusion syndrome (CHS) perioperatively. External carotid artery (ECA) occlusion occurred in 1.9%. Four patients experienced jaw claudication (3.8%) postoperatively. Mean time of operation was 41 minutes. Mean duration of hospitalization was 3.1 days. The 30-day rate of MAE was 0%. CGuard patency was 100%, mean internal carotid PSV was reduced from 251.57 to 77.29 cm/s, and mean internal carotid EDV was reduced from 154.62 to 24.63 cm/s at 30 days. CONCLUSION Our study shows that CGuard stent with EPS is an effective and safe device for treatment of carotid artery stenosis with acceptable low perioperative neurologic events, even with low embolic protection device usage. Larger multicenter and randomized studies are necessary to confirm its long-term efficacy.

Abstract
INTRODUCTION Prevention of peri- and postprocedural complications is still a challenge in carotid artery stenting (CAS). AIM To assess immediate and long-term safety and effectiveness of CAS using the Roadsaver double-nitinol-layer-micromesh stent. MATERIAL AND METHODS Since 2014, 298 CAS procedures in 287 non-consecutive patients (203 men, mean age 70.5 ±8.6 years, 100% symptomatic/high risk lesions) have been performed using the Roadsaver stent and proximal (40%) or distal (60%) neuroprotection system. Clinical and neurological examinations as well as duplex ultrasound were completed before CAS, before discharge, at 1, 6 and 12 months, then annually. RESULTS All CAS procedures were successful. Carotid stenosis was reduced from 84.9 ±9.9% to 11.0 ±9.4% (p < 000.1). In hospital, 1 ipsilateral periprocedural major (0.3%) and 3 minor (1.34%) ischemic strokes occurred, 2 (0.7%) patients died due to a cerebral hemorrhage on day 9 and 21. Three (1.0%) additional ipsilateral minor strokes within 30 consecutive days occurred. Thus, 30-day complications were observed in 9 (3.0%) patients. Two minor strokes were associated with in-stent thrombosis (0.7%). The 4-year follow-up showed 82% overall survival (95% CI: 69-91%) with no significant difference between asymptomatic (77%) and symptomatic patients (97%; p = 0.076). The stroke-free survival was 89% (95% CI: 77-95%), 84% asymptomatic vs. 98% symptomatic (p = 0.187). Seven (2.3%) patients developed > 50% in-stent restenosis. CONCLUSIONS Carotid artery stenting using the Roadsaver stent for symptomatic patients and high risk lesions showed to be safe and effective, with a low complication rate and acceptable in-stent restenosis risk in 4-year follow-up.

Abstract
INTRODUCTION The prevention of atherosclerotic plaque fragmentation during carotid artery stenting is a fundamental problem in decreasing the risk of disability of patients. The goal of this review is to clarify whether the stent design can have a decisive impact on the rate of intraoperative and postoperative complications. AREAS COVERED Different designs of the carotid stents are briefed and the advantages and disadvantages of different stent designs are discussed as well as the results of their clinical use. Various solutions are presented to reduce cerebral embolism during carotid artery stenting. EXPERT OPINION There is no conclusive evidence for the benefits of closed cell and hybrid stents. The stent design cannot completely resolve the problem of cerebral embolism. Most of the events of cerebral microembolism occur at the stages of stent delivery rather than protrusion of an atherosclerotic plaque in the long-term follow-up. Most likely, minimization of the risks for periprocedural and postprocedural strokes requires not only the new solutions in stent design as well as the corresponding delivery systems and brain embolic protection systems, but also the new strategies of preprocedural drug stabilization of the atherosclerotic plaque in the carotid artery.

Abstract
Carotid artery stenting (CAS) has recently emerged as a potential alternative to carotid endarterectomy (CEA) in Japan. However, one of its disadvantages is the higher incidence of ischemic complications than CEA, such as distal embolism during or after the procedure. Plaque protrusion (PP) through the stent strut after deployment of the stent has been suggested as one of the major causes of distal embolism, especially in patients with unstable plaques. The need for increased plaque coverage to reduce the risk of PP through the stent struts has led to the development of a double-layer micromesh stent (micromesh stent) system. This stent system has already been used clinically in European countries with good short- to medium-term follow-up results. Also clinical trials evaluating micromesh stents have been completed in Japan. Hence, usefulness of the micromesh stent for CAS is expected. According to the results of several clinical studies, CAS with the double-layer micromesh stent has the potential to minimize distal embolism during or after the procedure even in patients with unstable plaques. However, it may not be suitable for emergency CAS at this point. Also, since results of only short- to medium-term follow-up have been reported, longer-term follow-up will be required in the near future.

Abstract
BACKGROUND AND PURPOSE Carotid artery stenting is an alternative to endarterectomy for the treatment of symptomatic carotid stenosis but was associated with a higher risk of procedural stroke or death in randomized controlled trials (RCTs). Technical aspects of treatment may partly explain these results. The purpose of this analysis was to investigate the influence of technical aspects such as stent design or the use of protection devices, as well as clinical variables, on procedural risk. METHODS We pooled data of 1557 individual patients receiving stent treatment in three large RCTs comparing stenting versus endarterectomy for symptomatic carotid stenosis. The primary outcome event was any procedural stroke or death occurring within 30 days after stenting. RESULTS Procedural stroke or death occurred significantly more often with the use of open-cell stents (61/595 patients, 10.3%) than with closed-cell stents (58/962 patients, 6.0%; RR 1.76; 95% CI 1.23 to 2.52; P=0.002). Procedural stroke or death occurred in 76/950 patients (8.0%) treated with protection devices (predominantly distal filters) and in 43/607 (7.1%) treated without protection devices (RR 1.10; 95% CI 0.71 to 1.70; P=0.67). Clinical variables predicting the primary outcome event were age, severity of the qualifying event, history of prior stroke, and level of disability at baseline. The effect of stent design remained similar after adjustment for these variables. CONCLUSIONS In symptomatic carotid stenosis, the use of stents with a closed-cell design is independently associated with a lower risk of procedural stroke or death compared with open-cell stents. Filter-type protection devices do not appear to reduce procedural risk.

Abstract
Multicenter clinical trials level 1 evidence favors the application of carotid endarterectomy in symptomatic patients, especially the in the elderly cohort. Carotid artery stenting has been proposed as a possible early alternative in selected patients after onset of ipsilateral neurologic symptoms. It is well known that treatment of acute stroke is time-dependent in patients with acute ischemic stroke caused by high-grade stenosis of the internal carotid artery, but intensive medical treatment in conjunction with intervention to improve stroke severity and clinical outcomes has not been established. Two major clinical concerns exist: (1) the risk of hemorrhagic infarction after cerebral revascularization in the acute stage and (2) application of carotid stenting in the acute embolic stage, which may be associated with continued embolic risk after carotid artery stenting compared to carotid endarterectomy, which removes the symptomatic plaque. This review summarizes the indications and results of early carotid artery stenting after onset of neurologic symptoms, considering the new carotid stents and cerebral protection systems available for clinical use and enhanced stenting techniques.

ADVANCES IN INTERVENTIONAL CARDIOLOGY 2017; 13:95-106.

Abstract
Atherosclerotic carotid artery stenosis (CS) continues to be a common cause of acute ischaemic stroke. Optimised medical therapy (OMT), the first-line treatment modality in CS, may reduce or delay - but it does not abolish - CS-related strokes. As per current AHA/ASA and ESC/ESVS/ESO guidelines, carotid artery stenting (CAS) is a less-invasive alternative to carotid endarterectomy (CEA) for CS revascularisation in primary and secondary stroke prevention. Ten-year follow-up from the CREST trial in patients with symptomatic and asymptomatic CS confirmed equipoise of CAS and CEA in the primary endpoint. Nevertheless CAS - using a widely open-cell, first-generation stent and first-generation (distal/filter) neuroprotection - has been criticised for its relative excess of (mostly minor) strokes by 30 days, a significant proportion of which were post-procedural. Atherosclerotic plaque protrusion through conventional carotid stent struts, confirmed on intravascular imaging, has been implicated as a leading mechanism of the relative excess of strokes with CAS vs. CEA, including delayed strokes with CAS. Different designs of mesh-covered carotid stents have been developed to prevent plaque prolapse. Several multi-centre/multi-specialty clinical studies with CGurad MicroNet-Covered Embolic Prevention Stent System (EPS) and RoadSaver/Casper were recently published and included routine DW-MRI cerebral imaging peri-procedurally and at 30 days (CGuard EPS). Data from more than 550 patients in mesh-covered carotid stent clinical studies to-date show an overall 30-day complication rate of ~1% with near-elimination of post-procedural events. While more (and long-term) evidence is still anticipated, these results - taken together with optimised intra-procedural neuroprotection in CAS (increased use of proximal systems including trans-carotid dynamic flow reversal) and the positive 12-month mesh-covered stent data reports in 2017 - are transforming the carotid revascularisation field today. Establishing effective algorithms to identify the asymptomatic subjects at stroke risk despite OMT, and large-scale studies with mesh-covered stents including long-term clinical and duplex ultrasound outcomes, are the next major goals.
