Abstract
Options for treatment of symptomatic carotid bifurcation disease include carotid endarterectomy (CEA) and carotid artery stenting (CAS). While over the years CEA has established itself as the gold standard for carotid artery revascularization, results from recent trials have shown CAS to be safe and effective in selected patients. This review details the evolution of carotid artery bifurcation disease by highlighting key clinical trials.

Abstract
BACKGROUND Carotid near-occlusion (CNO) represents an anatomical-functional condition characterized by severe (more than 90%) internal carotid artery stenosis which can lead to a distal lumen diameter greater or less than 2 mm. CNO can be divided into a less severe subgroup (without lumen full collapse: diameter >2 mm) and a more severe subgroup (with lumen full collapse: diameter <2 mm). The decision for revascularization is still highly debated in Literature. The aim of the present multicenter retrospective study is to analyze the incidence of perioperative (30 days) and follow-up complications in 2 groups of patients with or without distal internal carotid lumen full collapse. METHODS Between January 2011 and March 2023, in 5 Vascular Surgery Units, 67 patients (49 male, 73% and 18 females, 27%) with CNO underwent carotid endarterectomy: 28 (41.7%) with lumen diameter <2 mm and 39 (58.3%) with diameter >2 mm. 19 patients were symptomatic and 48 asymptomatic. The outcomes considered for comparative analysis were: perioperative neurological and cardiac complications, carotid restenosis or occlusion at follow-up. Both groups were homogeneous in terms of risk factors, morphological features and pharmacological treatments. RESULTS In the group with lumen <2 mm, 3 perioperative major events (10.7%) occurred (1 ischemic stroke, 1 hemorrhagic stroke, 1 myocardial infarction) and 2 (7.1%) at follow-up (average 11 ± 14.5 months; 1 asymptomatic carotid occlusion, 1 hemodynamic restenosis treated with stenting). No event was recorded in the group with lumen >2 mm. CONCLUSIONS According to our results CNO patients show different complication risk according to the presence or not of distal lumen collapse. The later seems to play a significant role in perioperative and follow-up complication rate. These results therefore support a surgical treatment only in patients with CNO without lumen full collapse.

Abstract
As the average life expectancy increases, neurosurgeons are likely to encounter patients aged 80 years and above with carotid stenosis; however, whether old age affects clinical post-treatment outcomes of carotid endarterectomy (CEA) or carotid artery stenting (CAS) remains inconclusive. Thus, this study aimed to evaluate the outcomes following CEA or CAS in patients aged 80 years and above. This study included older over 80 years (n = 34) and younger patients (<80 years; n = 222) who underwent CEA or CAS between 2012 and 2022. All of them were followed up for a mean of 55 months. All-cause mortality, the incidence of vascular events, ability to perform daily activities, and nursing home admission rates were assessed. During follow-up periods, 34 patients (13.3%) died due to coronary artery disease, malignancy, and pneumonia, and the incidence was significantly higher in the elderly group than in the younger group (P = 0.03; HR, 3.01; 95% CI, 1.53-5.56). The incidence of vascular events did not differ between the older group (29.5%) and the younger group (26.9%, P = 0.58); however, the incidence was significantly higher in patients with high-intensity plaques than in those without that (P = 0.008; HR, 2.83, 95%CI, 1.27-4.87). The decline in the ability to perform daily activities and increased nursing home admission rates were high in elderly patients (P < 0.01). Although the mortality rate was higher in the elderly group, subsequent vascular events were comparable to that in the younger group. The results suggest that CEA and CAS are safe and useful treatments for carotid stenosis in older patients, especially to prevent ipsilateral ischemic stroke.

Abstract
OBJECTIVE Little guidance exists on the conduct of randomised clinical trials (RCT) that seek to randomise patients away from standard of care. We sought to test the technique of network meta-analysis (NMA) to ascertain best available evidence for the purposes of informing the ethical evaluation of RCTs under these circumstances. We used the example of RCTs for patients with symptomatic, moderate to severe carotid stenosis that seek to compare surgical intervention plus medical therapy (standard of care) versus medical therapy (less than standard of care). STUDY DESIGN AND SETTING Network meta-analysis of RCTs of adults with symptomatic carotid artery stenosis of 50%-99% who were treated with carotid endarterectomy (CEA), carotid artery stenting (CAS), or medical therapy (MT). The primary outcome was any stroke or death until end of follow-up, and secondary outcome was 30-day risk of ipsilateral stroke/death. RESULTS We analysed eight studies, with 7187 subjects with symptomatic moderate/severe stenosis (50%-99%). CEA was more efficacious than MT (HR = 0.82, 95% credible intervals [95% CrI] = 0.73-0.92) and CAS (HR 0.73, 95% CrI = 0.62-0.85) for the prevention of any stroke/death. At 30 days, the odds of experiencing an ipsilateral stroke/death were significantly lower in the CEA group compared to both MT (OR = 0.58, 95% CrI = 0.47-0.72) and CAS (OR = 0.68, 95% CrI = 0.55-0.83). CONCLUSION Our results support the feasibility of using NMA to assess best available evidence to inform the ethical evaluation of RCTs seeking to randomise patients away from standard of care. Our results suggest that a strong argument is required to ethically justify the conduct of RCTs that seek to randomise patients away from standard of care in the setting of symptomatic moderate to severe carotid stenosis.

Abstract
OBJECTIVES To analyze the outcomes of carotid endarterectomy in individuals with carotid artery stenosis in the context of a tertiary care center. METHODS We carried out a retrospective cohort investigation between 2015-2022. Patient data includes demographics, risk factors, preoperative medications, and operative details. The primary outcomes were 30-day postoperative stroke and mortality rates, while the secondary outcome of the study was to assess the morbidity of the procedure. RESULTS The mean age of the 54 patients was 66.9±9.88 years, and 57.4% were men. The 30-day stroke rate was 3.7%, and the mortality rate was 1.9%. Most patients did not develop postoperative complications; however, surgical site hematoma was the most common complication encountered (12.9%). Long-term follow-up showed disease regression in 68.5% of patients, with a minority of patients developing ipsilateral restenosis. Admission to an intensive care monitoring unit was the only independent predictor of postoperative complications. CONCLUSION This study provided insights into the outcomes of carotid endarterectomy in patients with carotid artery stenosis, emphasizing the importance of careful patient selection and postoperative monitoring. Perioperative risks, including stroke and mortality, were within acceptable limits. Further research incorporating structured and non-structured data for predictive analyses, should explore refining patient profiling and optimizing treatment approaches for different carotid artery stenosis clinical and morphological presentations.

Abstract
Carotid endarterectomy is the main way to combat atherosclerosis of the carotid arteries, which disrupts cerebral circulation. The generally accepted marker of atherogenesis risk are hemodynamic indices associated with near-wall shear stress. The purpose of the work is to conduct a comparative analysis of hemodynamic indices in various carotid bifurcation models. The influence of a virtual change in the geometric shape of the model in order to optimize hemodynamic indices is also being studied. On the basis of computed angiography data, carotid bifurcation models are constructed, in which critical zones of hemodynamic indices are built using computational fluid dynamics. A comparative analysis of the critical zones for different classes of models is carried out. Comparison of averaged indices for critical zones between 'normal' and post-operative groups gave more than 5-x worse results for the latter. The same results for the near-bifurcation parts of the zones give a 25% better result for postoperative models. Virtual 'removal' of insignificant plaques leads to a deterioration of the indices of up to 40% in the places of the plaque's former location. The described method makes it possible to build the indices critical zones and compare them for various types of models. A technique for virtual changing the shape of a vessel (virtual surgery) is proposed. The novelty of the approach lies in the use for comparative analysis both real vessel models and hypothetical 'improved' virtual ones, as well in the proposed division of post-operative model's critical zones into subzones of different genesis.

Abstract
BACKGROUND Carotid artery stenosis causes up to 20% of ischemic strokes. Stenting is used as an alternative to endarterectomy in symptomatic patients. Each commercially available stent offers numerous stent diameters/lengths. Most centers thus carefully match each individual stenosis to a specific stent length/diameter stent size. However, this process can be time-consuming and costly while the relative benefit of a custom stent sizing versus one-size-fits-all approach has not been well evaluated yet. We hypothesized that a 'one-size-fits-all' default approach to carotid stenting results in comparable results to a customized approach. METHODS We conducted a descriptive retrospective cohort study on 154 patients who presented to our academic carotid revascularization clinic with symptomatic carotid artery stenosis who underwent carotid artery stenting for peri- and postprocedural carotid artery stenting complications. The primary outcomes were periprocedural (within 24 hours of the procedure) or postprocedural (within 30 days of the procedure) TIA, stroke, or death. The secondary outcome was the estimated degree of stenosis on follow-up ultrasound performed within 6 months of the procedure. RESULTS The complication rate within the first 24 hours was 4.5% while that during the first 30 days postprocedure was 6.5%. Age over 80 and degree of stenosis on postprocedural cerebral angiogram were associated with an increased risk of complications. Severe restenosis was reported in 16.8% of patients within 6 months postprocedure. CONCLUSION Our study suggests that using a simplified, one-size-fits-all, approach to carotid stenting results in safe and effective outcomes, suggesting an alternative to simplify a complex medical procedure.

Abstract
INTRODUCTION AND OBJECTIVES Carotid cross-clamping during carotid endarterectomy might lead to intraoperative neurologic deficits, increasing stroke/death risk. If deficits are detected, carotid shunting has been recommended to reduce the risk of stroke. However, shunting may sustain a specific chance of embolic events and subsequently incurring harm. Current evidence is still questionable regarding its clear benefit. The aim is to determine whether a policy of selective shunt impacts the complication rate following an endarterectomy. MATERIAL AND METHODS From January 2013 to May 2021, all patients undergoing carotid endarterectomy under regional anesthesia with intraoperative neurologic alteration were retrieved. Patients submitted to selective shunt were compared to a non-shunt group. A 1:1 propensity score matching (PSM) was performed. Differences between the groups and clinical outcomes were calculated, resorting to univariate analysis. RESULTS Ninety-eight patients were selected, from which 23 were operated on using a shunt. After PSM, 22 non-shunt patients were compared to 22 matched shunted patients. Concerning demographics and comorbidities, both groups were comparable to pre and post-PSM, except for chronic heart failure, which was more prevalent in shunted patients (26.1%, P=0.036) in pre-PSM analysis. Regarding 30-day stroke and score Clavien-Dindo ≥2, no significant association was found (P=0.730, P=0.635 and P=0.942, P=0.472, correspondingly, for pre and post-PSM). CONCLUSIONS In this cohort, resorting to shunting did not demonstrate an advantage regarding 30-day stroke or a Clavien-Dindo ≥ 2 rates. Nevertheless, additional more extensive studies are mandatory to achieve precise results concerning the accurate utility of carotid shunting in this subset of patients under regional anesthesia.

Abstract
AIM Analysis of in-hospital and long-term results of carotid endarterectomy (CEE) in patients with different severity of coronary atherosclerosis. MATERIAL AND METHODS This comparative, retrospective, open study for the period from January 2013 to April 2020 included 1719 patients operated on for occlusive-stenotic lesions of the internal carotid arteries (ICA). Classical and eversion CEA were used as revascularization strategies. The criteria for inclusion in the study were: 1. Presence of coronary angiography within six months before the present CEE; 2. A history of myocardial revascularization in patients with severe coronary lesions. Depending on the severity of coronary atherosclerosis, all patients were divided into 3 groups: Group 1-871 (50.7 %) patients - with the presence of hemodynamically significant stenosis of the coronary arteries (CA) with a history of myocardial revascularization; Group 2-496 (28.8 %) patients - with the presence of hemodynamically insignificant lesions of the coronary artery (up to 70 %, not inclusive, and the trunk of the left coronary artery, up to 50 %, not inclusive); Group 3-352 (20.5 %) patients - without signs of atherosclerotic lesions of the coronary artery. In group 1, the observation period was 56.8±23.2 months, in group 2-62.0±15.6 months, in group 3-58.1±20.4 months. RESULTS During the hospital observation period, there were no significant intergroup differences in the number of complications. All cardiovascular events were detected in isolated cases. The most common injury was damage to the cranial nerves, diagnosed in every fifth patient in the total sample. The combined endpoint (CET), including death + myocardial infarction (MI) + acute cerebrovascular accident/transient ischemic attack (stroke/TIA), was 0.75 % (n=13). In the long-term follow-up period, when comparing survival curves, group 3 revealed the largest number of ischemic strokes (p = 0.007), myocardial infarction (p = 0.03), and CCT (p = 0.005). There were no intergroup differences in the number of deaths (p=0.62). CONCLUSION The results of the study showed that there was no significant intergroup difference in the development of complications at the hospital postoperative stage. However, in the long-term follow-up period, a group of patients with isolated lesions of the ICA demonstrated a rapid increase in the number of MI, stroke/TIA, and a combined endpoint, which was apparently associated with low compliance and progression of atherosclerosis in previously unaffected arteries.

Abstract
BACKGROUND Previous literature has established an association between acute silent ischemic lesions (ASILs) and elevated susceptibility to future adverse clinical outcomes. The present study endeavors to scrutinize the prognostic significance of preprocedural ASILs, as detected through diffusion-weighted imaging and apparent diffusion coefficient metrics, in relation to subsequent adverse events-namely, stroke, myocardial infarction, and all-cause death-following carotid revascularization in a cohort of patients with symptomatic carotid stenosis. MATERIALS AND METHODS Subjects were extracted from a comprehensive retrospective dataset involving symptomatic carotid stenosis cases that underwent carotid revascularization at a tertiary healthcare institution in China, spanning January 2019 to March 2022. Of the 2663 initially screened patients (symptomatic carotid stenosis=1600; asymptomatic carotid stenosis=1063), a total of 1172 individuals with symptomatic carotid stenosis were retained for subsequent analysis. Stratification was implemented based on the presence or absence of ASILs. The primary endpoint constituted a composite measure of in-hospital stroke, myocardial infarction, or all-cause death. Both carotid endarterectomy (CEA) and carotid artery stenting (CAS) treatment modalities were individually subjected to propensity score-matched analyses. RESULTS Among the 584 subjects who underwent CEA, 91 ASIL-positive and 91 ASIL-negative (NASIL) cases were propensity score-matched. Notably, the ASIL cohort demonstrated a statistically significant augmentation in the risk of primary outcomes relative to the NASIL group [10.99 vs. 1.10%; absolute risk difference, 9.89% (95% CI: 3.12-16.66%); RR, 10.00 (95% CI: 1.31-76.52); P =0.01]. Similarly, within the 588 CAS-treated patients, 107 ASIL-positive and 107 NASIL cases were matched, revealing a correspondingly elevated risk of primary outcomes in the ASIL group [9.35 vs. 1.87%; absolute risk difference, 7.48% (95% CI: 1.39-13.56%); RR, 5.00 (95% CI: 1.12-22.28); P =0.02]. CONCLUSIONS ASILs portend an elevated risk for grave adverse events postcarotid revascularization, irrespective of the specific revascularization technique employed-be it CEA or CAS. Thus, ASILs may serve as a potent biomarker for procedural risk stratification in the context of carotid revascularization.

Abstract
OBJECTIVE Current societal guidelines recommend duplex ultrasound (DUS) surveillance beyond 30 days after carotid endarterectomy (CEA) for patients with risk factors for restenosis or who underwent primary closure. However, the appropriate duration of this surveillance has not yet been identified, and the rate at which DUS surveillance prompts intervention is unknown. Multiple calls for decreasing health care spending that does not provide value, including unnecessary testing, have been made. The purpose of this study was to examine the rate of intervention prompted by surveillance DUS on the ipsilateral or contralateral carotid artery after CEA and determine the value of continued surveillance by determining the rate of DUS-prompted intervention. METHODS A single-center, retrospective chart review of all patients older than 18 years who had undergone CEA from August 2009 to July 2022 was performed. Patients with at least one postoperative duplex in our Intersocietal Accreditation Council-accredited ultrasound lab were included. Exclusion criteria were patients with incomplete medical charts or patients who underwent a concomitant procedure. The primary end point was return to the operating room for subsequent intervention based on abnormal surveillance DUS findings. Secondary end points were the number of postoperative surveillance duplexes, duration of surveillance, and incidence of perioperative stroke. The study participant data were queried for patients who had a diagnosis of stroke that occurred following their procedure. RESULTS A total 767 patients, accounting for 771 procedures, were included in this study, which resulted in 2145 ultrasound scans. A total of 40 (5.2%) patients required 44 subsequent interventions that were prompted by DUS surveillance scans. The average number of ultrasound scans per patient was 2.8 (range: 0-14), and the average duration of surveillance was 26.4 months (range: 0-155 months). Of the 767 patients, 669 (87.2%) had a unilateral CEA. A total of 62 of 767 (8.1%) patients had planned endarterectomies on the contralateral side based on initial imaging, not prompted by interval DUS surveillance scans. Of 767 patients, 28 (3.7%) patients who underwent CEA had a subsequent procedure for progression of contralateral disease, which was prompted by duplex surveillance scans. The average duration between index CEA and intervention on contralateral carotid was 29.57 months (range: 3-81 months). A total of 11 patients, accounting for 12 procedures, underwent a subsequent procedure for restenosis of their ipsilateral carotid, prompted by duplex surveillance scans. The average duration between index CEA and reintervention on the ipsilateral carotid was 17.9 months (range: 4-70 months). Three of 767 (0.4%) patients in total were identified as having a perioperative stroke. CONCLUSIONS The overall rate of ipsilateral reintervention after CEA is low. A small percentage of patients will progress their contralateral disease, ultimately requiring surgical intervention. These data suggest that regular duplex surveillance after CEA is warranted for patients with at least moderate contralateral disease; however, the yield is low for ipsilateral restenosis after 36 months based on this single institution study. Further study is needed to better delineate which patients need follow-up to decrease unnecessary testing while still targeting patients most at risk of restenosis or contralateral progression of disease.

Abstract
OBJECTIVE The aim of this study was to conclude the safety and effectiveness of hybrid surgery for revascularization of chronic occlusion of internal carotid artery (COICA). METHODS A total of 56 COCIA patients underwent hybrid surgery (carotid endarterectomy+carotid artery stenting) from September 2017 to September 2021 in our department. The clinical material and radiology data (preoperation and postoperation) were retrospectively analyzed to conclude the safety and effectiveness of hybrid surgery for revascularization of COICA. RESULTS All 56 patients underwent hybrid surgery got revascularization successfully (with a successful rate of 100%) and improved intracranial blood flow. The computed tomography perfusion results indicate that the postoperative cerebral blood flow perfusion of the patient is significantly improved compared with before surgery. In 1 patient, postoperative brain magnetic resonance imaging within 24 hours showed spotted fresh infarction with head magnetic resonance imaging, without any clinical symptoms; 3 patients developing symptoms of ipsilateral neural-functional defect (hypoglossal nerve, superior laryngeal nerve, and mandibular branch of facial nerve, respectively), 2 weeks later the symptoms were disappeared. Imaging study at 3 and 6 months during the follow-up showed no abnormalities. CONCLUSION Hybrid surgery is safe and effective for revascularization of COICA.

Abstract
Carotid endarterectomy is preferable for prevention of acute cerebrovascular accident associated with atherosclerotic lesions of internal carotid artery. Modern interest in minimizing local complications and small excisions is also actual in carotid surgery. The authors review the modern literature data on evolution of carotid arteries exposure. Cutaneous mini-incision, transverse skin incision and retrojugular approach are discussed. The authors consider the advantages and possible complications of each technique.

Abstract
Carotid artery stenting (CAS) represents today an accepted option for the treatment of severe carotid artery stenosis. The evolution of materials, techniques, perioperative medical management and patients' selection, has allowed to progressively reduce CAS complications. However, the main drawback of CAS is still represented by the risk of cerebral embolization, that may occur during several steps of the procedure and also in the early postoperative period. Preoperative carotid plaque morphological characteristics may have a great role in determining the risk of embolization during CAS. This review summarizes the current knowledge on carotid plaque characteristics that may influence the risk of complication during CAS. This information may be important for the optimization of CAS patients' selection and adaptation of the materials and techniques.

Abstract
In revascularization of internal carotid stenosis with carotid vertebrobasilar anastomoses, attention should be paid not only to the anterior circulation but also to the posterior circulation cerebral infarction. A 74-year-old man was referred for treatment of carotid artery stenosis; NASCET 75% stenosis in the right internal carotid artery and acute cerebral infarction were confirmed. Occlusion of the left subclavian artery and vascular anastomosis between the right external carotid artery and the vertebral artery were indicated, such that the right external carotid artery may maintain blood flow to the vertebrobasilar artery. Therefore, dual shunts were used for the common and internal carotid arteries and the common and external carotid arteries to maintain blood flow during carotid endarterectomy. Management of the dual shunts is difficult due to the instable parallel placement of the common carotid artery shunt balloons. To solve this problem, the "dual internal shunts technique" was performed. The first shunt was inserted into the external and common carotid arteries, and the second into the internal and common carotid arteries. The shunt balloon on the common carotid artery side was placed distal to the first shunt balloon so that the dual balloons were placed in a tandem position. The proximal balloon was subsequently deflated gradually to improve flow in both shunts. The procedure is technically easy and safe.

Abstract
OBJECTIVES Patients sometimes present with high cervical internal carotid artery (ICA) stenosis. This study demonstrates the usefulness of the transstyloid approach to expose the distal ICA by dissection of the styloid diaphragm covering the distal cervical ICA for carotid endarterectomy (CEA). In particular, the possible exposure length achieved by this approach was investigated using cadaveric heads. METHODS The procedure of the transstyloid diaphragm approach was confirmed in 10 cadaveric heads (20 sides). After the carotid triangle was opened, both the posterior belly of the digastric muscle (PBDM) and the stylohyoid muscle could be divided. Then, the carotid sheath was dissected, and the glossopharyngeal nerve was identified crossing over the distal ICA. The revealed length of the ICA was measured with or without dissection of both the PBDM and the stylohyoid muscle. The specimens were dissected under the surgical microscope. RESULTS The transstyloid diaphragm approach was achieved successfully in all specimens. The revealed lengths of the ICA with and without dissection of the styloid diaphragm were 53.7 ± 5.9 mm and 38.8 ± 2.9 mm (mean ± standard deviation), respectively. Therefore, the revealed length of the distal ICA was 14.9 ± 4.5 mm greater using the transstyloid diaphragm approach compared to the regular CEA approach. CONCLUSIONS More of the ICA can be revealed by dissection of both the PBDM and the stylohyoid muscle. The transstyloid diaphragm approach might be helpful to reveal the distal ICA in cases of high cervical ICA stenosis.

Abstract
OBJECTIVE Stroke following a coronary artery bypass surgery is a well-known complication often predisposed by carotid artery disease. Perioperative risk of stroke after on-pump cardiac surgery can overall affect 2% of patients. Patients with 80-99% unilateral carotid artery stenosis carry a 4% risk of stroke. Significant carotid artery stenosis is present in 3-10% of patients who are candidates for coronary artery bypass grafting (CABG). Those patients might be considered for either simultaneous or staged carotid endarterectomy and CABG to reduce the risk of stroke and death. The purpose of this study was to evaluate preoperative and intraoperative risk factors for myocardial infarction (MI), stroke and death and assess complications occurring during the early postoperative period after simultaneous CABG/CAE procedure. METHODS A single centre retrospective analysis of 134 patients from 2015 to 2019 who underwent simultaneous CABG/CEA was performed. At the same period, a total of 2827 CABG were performed, of which 4.7% were simultaneous interventions. We excluded staged CEA/CABG procedures, off-pump CABG and urgent CABG patients. All patients included in the study met the criteria for elective CABG for triple-vessel or left main trunk symptomatic coronary artery disease (CAD) with asymptomatic >70% carotid stenosis or symptomatic ipsilateral >50% carotid stenosis regardless of the degree of contralateral carotid artery stenosis. Patient demographics, comorbidities and operative details were reviewed. The primary endpoint was to assess the intraoperative and 30-day risk of stroke and death after simultaneous CEA/CABG procedure. RESULTS Simultaneous CEA/CABG is effective procedure that can be performed in high-risk symptomatic patients with acceptable results. Predictors of postoperative stroke were smoking (P = 0.011), history of MI (P = 0.046), history of CABG (P = 0.013), and history of stroke/TIA (P = 0.005). Significant risk factors for adverse major postoperative complications after simultaneous CEA/CABG procedure were cardiac arrhythmia (AF or AFL) (P = 0.045), previous MI (P < 0.001), and smoking (P = 0.001). CONCLUSIONS Synchronous CEA/CABG procedure can be performed with acceptable results in patients having a high risk of stroke, septuagenarians and older.

Abstract
AIM To compare the long-term results of eversion (ECEA) and conventional carotid endarterectomy (CCEA). METHODS We designed a retrospective, multicenter study which included 25,106 patients who underwent ECEA (n = 18,362) or CCEA (n = 6744). The duration of follow-up was 124.7 ± 53.8 months. RESULTS In the postoperative period, none of the interventions showed clear benefits reducing the frequency of complications: fatal outcome (ECEA: 0.19%, n = 36; CCEA: 0.17%, n = 12; OR = 1.1, 95% CI = 0.57-2.11, p = 0.89), myocardial infarction (ECEA: 0.15%, n = 28; CCEA: 0.13%, n = 9; p = 0.87; OR = 1.14; 95% CI = 0.53-2.42); acute cerebrovascular accident (CVA) (Group I: 0.33%, n = 62; Group II: 0.4%, n = 27; p = 0.53; OR = 0.84; 95% CI = 0, 53-1.32); bleeding with acute haematoma appearance in the area of intervention (Group I: 0.39%, n = 73; Group II: 0.41%, n = 28; p = 0.93; OR = 0.95; 95% CI = 0, 61-1.48); internal carotid artery (ICA) thrombosis (Group I: 0.05%, n = 11; Group II: 0.07%, n = 5; OR = 0.80, 95% CI = 0.28-2.32, p = 0.90). During the long-term follow-up, ECEA was associated with lower frequency of fatal outcome (ECEA: 2.7%, n = 492; CCEA: 9.1%, n = 616; OR = 0.27; 95% CI = 0.24-0.3, p < 0.0001), cerebrovascular death (ECEA: 1.0%, n = 180; CCEA: 5.5%, n = 371; OR = 0.17, 95% CI = 0.14-0.21, p < 0.0001), non-fatal ischaemic stroke (ECEA: 0.62%, n = 114; CCEA: 7.0%, n = 472; OR = 0.08; 95% CI = 0.06-0.1, p < 0.0001); repeated revascularization because of >60% restenosis (ECEA: 1.6%, n = 296; CCEA: 12.6%, n = 851; OR = 0.11, 95% CI = 0.09-0.12, p < 0.0001), and combined endpoint (ECEA: 2.2%, n = 397; CCEA: 13.2%, n = 888; OR = 0.14; 95% CI = 0.12-1.16, p < 0.0001). CONCLUSION ECEA is beneficial over CCEA in a long term.

Abstract
BACKGROUND The aim of this study was to establish the relationship between arterial hypertension (AH) and hemodynamically significant atherosclerotic stenosis of carotid bifurcation and study the effect of carotid endarterectomy (CEA) on the course of AH. METHODS In our investigation we included 320 patients: 243 (75.9%) men and 77 (24.1%), the mean age - 59.6±8.2. All patients underwent CEA operation. Patients were divided into groups: I (320) - before CEA surgery and AH; II (320) - the same patients after CEA operation. All patients underwent laboratory tests, ECG, chest X-ray, ultrasound of the kidneys, thyroid gland, computer tomography (CT) of adrenal glands, of the brain, echocardiography, ultrasound or angiography of the renal arteries. Before and after the CEA, there were made Doppler ultrasound of brachiocephalic arteries, 24 hours blood pressure (BP) monitoring. Additional visits were made by 73 patients in 3, 6 and 12 months after the CEA. RESULTS Most of the patients had significant decrease of BP in the postoperative period, which was observed in 257 (80.3%) patients on days 2-7, in 58 (18.1%) - did not change significantly, and only 5 (1.6%) had the increasing of BP. In 29 (39.7%) patients 1 year after CEA, there was no need to use antihypertensive therapy due for the normalization of BP after the surgery. CONCLUSIONS It is necessary to highlight the cerebrovascular AH into a separate form of the secondary AH. The CEA has prominent, stable antihypertensive effect on these patients.

Abstract
BACKGROUND Several studies have shown the superiority of carotid endarterectomy (CEA) with patch closure over primary closure. However, no definite study has shown any significant differences in clinical outcome between various types of patches. Because more vascular surgeons have used pericardial patching recently, this study will analyze the late clinical outcome (≥10 years) of our previously reported prospective randomized trial comparing CEA with ACUSEAL (polytetrafluoroethylene) vs pericardial patching. METHODS A total of 200 CEAs were randomized (1:1) to either Vascu-Guard pericardial patching or ACUSEAL patching. All patients had immediate duplex ultrasound imaging, which was repeated at 6 months and annually thereafter. Kaplan-Meier analysis was used to estimate rates of freedom from stroke, stroke-free survival, and rates of freedom from ≥50% and ≥80% restenosis. RESULTS Overall demographic and clinical characteristics were somewhat similar with a mean follow-up of 80 months (range: 0-149 months). The rates of freedom from stroke were 97, 97, 97, 96, 93 for ACUSEAL vs 99, 98, 97, 97, 92 for pericardial patching (P = .1112) at 1, 2, 3, 5, and 10 years, respectively. Similarly, the rates of freedom from stroke/death were 94, 93, 90, 76, 50 for ACUSEAL vs 99, 96, 91, 78, 47 for pericardial patching (P = .8591). The rates of freedom from ≥50% restenosis were 98, 98, 96, 89, 79 for ACUSEAL vs 87, 83, 83, 81, 71 for pericardial patching (P = .0489). The rates of freedom from ≥80% restenosis were 99, 99, 99, 96, 85 for ACUSEAL vs 96, 96, 96, 93, 93 for pericardial patching (P = .9407). The overall survival rates were 95, 94, 91, 77, 51 for ACUSEAL vs 100, 98, 93, 79, 50 for pericardial patching (P = .9123). Other patch complications (eg, rupture, aneurysmal dilation, infection, etc) were similar. CONCLUSIONS Both CEA with ACUSEAL (polytetrafluoroethylene) and pericardial patching are durable and have similar clinical outcomes at 10 years except that ACUSEAL patching has significantly better rates of freedom from ≥50% restenosis.

Abstract
Here, we describe a case of a 67-year-old man who was transferred to our hospital with complaints of sudden upper right limb weakness and ataxia. Scattered acute cerebral infarction was found in the watershed zone between the left anterior cerebral artery and the middle cerebral artery territories. A shelf-like structure at the origin of the left carotid artery and a vulnerable plaque distal to the lesion was found. Symptomatic atherosclerotic plaque with concomitant carotid web was diagnosed. Carotid endarterectomy resulted in good revascularization. Hemodynamic changes associated with vascular stenosis are involved in atherosclerosis. The current case is valuable and shows that carotid web can cause not only embolic infarction but also cerebral thrombosis due to atheroma formation in the carotid artery.

Abstract
INTRODUCTION Carotid endarterectomy (CEA) is usually performed using the anterior cervical triangle as a surgical corridor but, when needed, the retromandibular space makes dissection of higher structures difficult in some cases. The posterior cervical triangle (PCT) can be useful in these demanding cases. METHODS We retrospectively reviewed cases from July 2013 to November 2019 in which PCT was used as an approach for CEA. The surgical technique used was explained, and the complications and evolution of the patients were analysed. RESULTS We found 7 CEAs performed through this approach, of which 2 presented transient trapezius paresis. There were no cases of severe complications in this series. CONCLUSION The PCT approach for performing CEA represents a useful and easy technique that avoids the need for mandibular mobilisation or osteotomies for lesions located in anatomically high carotid bifurcations.

Abstract
OBJECTIVE Bovine pericardial patch (BPP) is currently used in femoral angioplasty as an alternative for autologous vein patch (AVP), but studies comparing the results of the two methods are scarce. In this retrospective study, we aimed to discover the differences between BPP and AVP closure in long-term durability. METHODS This study consisted of all femoral endarterectomies with BPP closure performed in Helsinki University Hospital from January 1, 2014, to December 31, 2017. For comparison, the same number of consecutive patients who underwent femoral endarterectomy with AVP closure from January 1, 2014, to October 16, 2016, were reviewed. Follow-up ended December 31, 2020. The mean follow-up was 19 months (range, 0-74 months) in the BPP group and 22 months (range, 0-79 months) in the AVP group. The primary endpoint was primary patency. Secondary endpoints were restenosis at patch site detected by imaging or perioperatively, patch rupture, and deep surgical wound infection. Propensity score analysis was performed for adjustment of differences between the AVP and BPP groups. RESULTS Overall primary patency was superior in the AVP group compared with the BPP group: at 1 year, 96.5% vs 85.0% and at 5 years, 83.0% vs 72.3% (P = .04). In propensity score-matched pairs (n = 92), no difference was found between the groups in primary patency: 95.7% and 95.7% at 1 year and 92.5% and 78.6% at 5 years (P = .861) or in freedom from restenosis: 100% and 100% at 1 year and 89.1% and 84.0% at 5 years (P = .057). Deep wound infections occurred slightly more often after BPP closure (8%) than after AVP closure (4%), but the difference was not statistically significant (P = .144). There were no patch ruptures in the BPP group, but in the AVP group, there were five ruptures (3.5%) (P = .024). CONCLUSIONS BPP is compatible to AVP in femoral endarterectomy in patency and can be regarded as the safer choice considering the risk of patch rupture.

Abstract
OBJECTIVE Common carotid artery occlusion (CCAO) is a rare cause of cerebrovascular events. Symptomatic lesions are resistant to medical treatment and revascularization is often required, but there is no consensus on the treatment of CCAO at present. Riles type 1A CCAO is most likely to benefit from revascularization because it has patent outflow tract (internal carotid artery) which was supplied by patent external carotid artery (ECA) from collateral circulation. We described a novel surgical technique improved on the basis of the carotid endarterectomy (CEA) for treatment of Riles type 1A CCAO. METHODS We rigorously screened ten patients with symptomatic Riles type1A CCAO for surgery from January 2017 to May 2019 and performed a full preoperative assessment of the inadequate collateral circulation compensation. Moreover, we retrospectively reviewed our experience of the segmented CEA in the treatment of them in our single center. RESULTS Segmented CEA was performed on the left side in four cases and on the right side in six cases. The technical success rate of the procedure was 100%. Primary suture was used in nine cases. Only one patient (right CCAO) who had a history of neck radiotherapy was treated by the patch CEA. The mean temporary blocking time during surgery was 52.8 ± 9.15 min. The mean temporary blocking time for treating the upper segment of the common carotid artery (CCA) was 11.1 ± 2.64 min. In the postoperative period, cerebral perfusion on the ipsilateral site improved in all patients, myocardial infarction occurred in one patient, and recurrent laryngeal nerve damage occurred in another. No ischemic events or re-occlusion or restenosis (> 50%) of the treated CCA occurred during the mean follow-up of 32.6 ± 9.3 months. The preoperative mean modified Rankin Scale (mRS) score was 1.9 (range, 1-3; median, 2). At last follow-up for all patients, the mRS score was 1 (range, 0-3; median, 1). CONCLUSION Segmented CEA, which utilizes the compensatory effect of collateral circulation, is an effective and safe technique to treat patients suffering from Riles type 1A CCAO with hemodynamic cerebrovascular compromise.

Abstract
Carotid revascularization is performed to prevent cerebrovascular events in patients with symptomatic (>50%) and asymptomatic high degree (>70%) carotid stenosis. As this operation carries significant risks for perioperative stroke, careful selection of patients who will benefit from the procedure is essential. Certain plaque characteristics, including texture, are associated with increased tendency for rupture and can be used to identify high-risk patients. Medical therapy, carotid endarterectomy, and carotid stenting are the mainstays for patient management. With careful selection of patients, all anesthesia techniques (general anesthesia, monitored anesthesia care, and regional anesthesia) can be used safely for these revascularization procedures.

Abstract
Patients undergoing vascular surgery tend to have significant systemic comorbidities. Vascular surgery itself is also associated with greater cardiac morbidity and overall mortality than other types of noncardiac surgery. Regional anesthesia is amenable as the primary anesthetic technique for vascular surgery or as an adjunct to general anesthesia. When used as the primary anesthetic, regional anesthesia techniques avoid complications associated with general anesthesia in this challenging patient population. In this article, the authors describe regional anesthetic techniques for carotid endarterectomy, arteriovenous fistula creation, lower extremity bypass surgery, and amputation.

Abstract
BACKGROUND Carotid endarterectomy (CEA) is the first-line surgical intervention for cases of severe carotid stenoses. Unfortunately, the restenosis rate is high after CEA. This study aims to demonstrate the predictive role of carotid plaque features and inflammatory biomarkers (monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic inflammatory index (SII), Systemic Inflammation Response Index (SIRI), and Aggregate Index of Systemic Inflammation (AISI)) in carotid restenosis and mortality at 12 months following CEA. METHODS The present study was designed as an observational, analytical, retrospective cohort study and included all patients over 18 years of age with a minimum of 70% carotid stenosis and surgical indications for CEA admitted to the Vascular Surgery Clinic, Emergency County Hospital of Targu Mures, Romania between 2018 and 2021. RESULTS According to our results, the high pre-operative values of inflammatory biomarkers-MLR (OR: 10.37 and OR: 6.11; p < 0.001), NLR (OR: 34.22 and OR: 37.62; p < 0.001), PLR (OR: 12.02 and OR: 16.06; p < 0.001), SII (OR: 18.11 and OR: 31.70; p < 0.001), SIRI (OR: 16.64 and OR: 9.89; p < 0.001), and AISI (OR: 16.80 and OR: 8.24; p < 0.001)-are strong independent factors predicting the risk of 12-month restenosis and mortality following CEA. Moreover, unstable plaque (OR: 2.83, p < 0.001 and OR: 2.40, p = 0.04) and MI (OR: 3.16, p < 0.001 and OR: 2.83, p = 0.005) were independent predictors of all outcomes. Furthermore, AH (OR: 2.30; p = 0.006), AF (OR: 1.74; p = 0.02), tobacco (OR: 2.25; p < 0.001), obesity (OR: 1.90; p = 0.02), and thrombotic plaques (OR: 2.77; p < 0.001) were all independent predictors of restenosis, but not for mortality in all patients. In contrast, antiplatelet (OR: 0.46; p = 0.004), statin (OR: 0.59; p = 0.04), and ezetimibe (OR:0.45; p = 0.03) therapy were protective factors against restenosis, but not for mortality. CONCLUSIONS Our data revealed that higher preoperative inflammatory biomarker values highly predict 12-month restenosis and mortality following CEA. Furthermore, age above 70, unstable plaque, cardiovascular disease, and dyslipidemia were risk factors for all outcomes. Additionally, AH, AF, smoking, and obesity were all independent predictors of restenosis but not of mortality in all patients. Antiplatelet and statin medication, on the other hand, were protective against restenosis but not against mortality.

Abstract
BACKGROUND The optimal treatment for patients with asymptomatic carotid artery stenosis is under debate. Since best medical treatment (BMT) has improved over time, the benefit of carotid endarterectomy (CEA) or carotid artery stenting (CAS) is unclear. Randomised data comparing the effect of CEA and CAS versus BMT alone are absent. We aimed to directly compare CEA plus BMT with CAS plus BMT and both with BMT only. METHODS SPACE-2 was a multicentre, randomised, controlled trial at 36 study centres in Austria, Germany, and Switzerland. We enrolled participants aged 50-85 years with asymptomatic carotid artery stenosis at the distal common carotid artery or the extracranial internal carotid artery of at least 70%, according to European Carotid Surgery Trial criteria. Initially designed as a three-arm trial including one group for BMT alone (with a randomised allocation ratio of 2·9:2·9:1), the SPACE-2 study design was amended (due to slow recruitment) to become two substudies with two arms each comparing CEA plus BMT with BMT alone (SPACE-2a) and CAS plus BMT with BMT alone (SPACE-2b); in each case in a 1:1 randomisation. Participants and clinicians were not masked to allocation. The primary efficacy endpoint was the cumulative incidence of any stroke or death from any cause within 30 days or any ipsilateral ischaemic stroke within 5 years. The primary safety endpoint was any stroke or death from any cause within 30 days after CEA or CAS. The primary analysis was by intention-to treat, which included all randomly assigned patients in SPACE-2, SPACE-2a, and SPACE-2b, analysed using meta-analysis of individual patient data. We did two-step hierarchical testing to first show superiority of CEA and CAS to BMT alone then to assess non-inferiority of CAS to CEA. Originally, we planned to recruit 3640 patients; however, the study had to be stopped prematurely due to insufficient recruitment. This report presents the primary analysis at 5-year follow-up. This trial is registered with ISRCTN, number ISRCTN78592017. FINDINGS 513 patients across SPACE-2, SPACE-2a, and SPACE-2b were recruited and surveyed between July 9, 2009, and Dec 12, 2019, of whom 203 (40%) were allocated to CEA plus BMT, 197 (38%) to CAS plus BMT, and 113 (22%) to BMT alone. Median follow-up was 59·9 months (IQR 46·6-60·0). The cumulative incidence of any stroke or death from any cause within 30 days or any ipsilateral ischaemic stroke within 5 years (primary efficacy endpoint) was 2·5% (95% CI 1·0-5·8) with CEA plus BMT, 4·4% (2·2-8·6) with CAS plus BMT, and 3·1% (1·0-9·4) with BMT alone. Cox proportional-hazard testing showed no difference in risk for the primary efficacy endpoint for CEA plus BMT versus BMT alone (hazard ratio [HR] 0·93, 95% CI 0·22-3·91; p=0·93) or for CAS plus BMT versus BMT alone (1·55, 0·41-5·85; p=0·52). Superiority of CEA or CAS to BMT was not shown, therefore non-inferiority testing was not done. In both the CEA group and the CAS group, five strokes and no deaths occurred in the 30-day period after the procedure. During the 5-year follow-up period, three ipsilateral strokes occurred in both the CAS plus BMT and BMT alone group, with none in the CEA plus BMT group. INTERPRETATION CEA plus BMT or CAS plus BMT were not found to be superior to BMT alone regarding risk of any stroke or death within 30 days or ipsilateral stroke during the 5-year observation period. Because of the small sample size, results should be interpreted with caution. FUNDING German Federal Ministry of Education and Research (BMBF) and German Research Foundation (DFG).

Abstract
BACKGROUND Carotid patch angioplasty may reduce the risk of acute occlusion or long-term restenosis of the carotid artery and subsequent ischaemic stroke in people undergoing carotid endarterectomy (CEA). This is an update of a Cochrane Review originally published in 1995 and updated in 2008. OBJECTIVES To assess the safety and efficacy of routine or selective carotid patch angioplasty with either a venous patch or a synthetic patch compared with primary closure in people undergoing CEA. We wished to test the primary hypothesis that carotid patch angioplasty results in a lower rate of severe arterial restenosis and therefore fewer recurrent strokes and stroke-related deaths, without a considerable increase in perioperative complications. SEARCH METHODS We searched the Cochrane Stroke Group trials register, CENTRAL, MEDLINE, Embase, two other databases, and two trial registries in September 2021. SELECTION CRITERIA Randomised controlled trials and quasi-randomised trials comparing carotid patch angioplasty with primary closure in people undergoing CEA. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility and risk of bias; extracted data; and determined the certainty of evidence using the GRADE approach. Outcomes of interest included stroke, death, significant complications related to surgery, and artery restenosis or occlusion during the perioperative period (within 30 days of the operation) or during long-term follow-up. MAIN RESULTS We included 11 trials involving 2100 participants undergoing 2304 CEA operations. The quality of trials was generally poor. Follow-up varied from hospital discharge to five years. Compared with primary closure, carotid patch angioplasty may make little or no difference to reduction in risk of any stroke during the perioperative period (odds ratio (OR) 0.57, 95% confidence interval (CI) 0.31 to 1.03; P = 0.063; 8 studies, 1769 participants; very low-certainty evidence), but may lower the risk of any stroke during long-term follow-up (OR 0.49, 95% CI 0.27 to 0.90; P = 0.022; 7 studies, 1332 participants; very low-certainty evidence). In the included studies, carotid patch angioplasty resulted in a lower risk of ipsilateral stroke during the perioperative period (OR 0.31, 95% CI 0.15 to 0.63; P = 0.001; 7 studies, 1201 participants; very low-certainty evidence), and during long-term follow-up (OR 0.32, 95% CI 0.16 to 0.63; P = 0.001; 6 studies, 1141 participants; very low-certainty evidence). The intervention was associated with a reduction in the risk of any stroke or death during long-term follow-up (OR 0.59, 95% CI 0.42 to 0.84; P = 0.003; 6 studies, 1019 participants; very low-certainty evidence). In addition, the included studies suggest that carotid patch angioplasty may reduce the risk of perioperative arterial occlusion (OR 0.18, 95% CI 0.08 to 0.41; P < 0.0001; 7 studies, 1435 participants; low-certainty evidence), and may reduce the risk of restenosis during long-term follow-up (OR 0.24, 95% CI 0.17 to 0.34; P < 0.00001; 8 studies, 1719 participants; low-certainty evidence). The studies recorded very few arterial complications, including haemorrhage, infection, cranial nerve palsies and pseudo-aneurysm formation, with either patch or primary closure. We found no correlation between the use of patch angioplasty and the risk of either perioperative or long-term stroke-related death or all-cause death rates. AUTHORS' CONCLUSIONS Compared with primary closure, carotid patch angioplasty may reduce the risk of perioperative arterial occlusion and long-term restenosis of the operated artery. It would appear to reduce the risk of ipsilateral stroke during the perioperative and long-term period and reduce the risk of any stroke in the long-term when compared with primary closure. However, the evidence is uncertain due to the limited quality of included trials.

Abstract
BACKGROUND This guideline (GL) on carotid surgery as updating of "Stroke: Italian guidelines for Prevention and Treatment" of the ISO-SPREAD Italian Stroke Organization-Group, has recently been published in the National Guideline System and shared with the Italian Society of Vascular and Endovascular Surgery (SICVE) and other Scientific Societies and Patient's Association. METHODS GRADE-SIGN version, AGREE quality of reporting checklist. Clinical questions formulated according to the PICO model. Recommendations developed based on clinical questions by a multidisciplinary experts' panel and patients' representatives. Systematic reviews performed for each PICO question. Considered judgements filled by assessing the evidence level, direction, and strength of the recommendations. RESULTS The panel provided indications and recommendations for appropriate, comprehensive, and individualized management of patients with carotid stenosis. Diagnostic and therapeutic processes of the best medical therapy, carotid endarterectomy (CEA), carotid stenting (CAS) according to the evidences and the judged opinions were included. Symptomatic carotid stenosis in elective and emergency, asymptomatic carotid stenosis, association with ischemic heart disease, preoperative diagnostics, types of anesthesia, monitoring in case of CEA, CEA techniques, comparison between CEA and CAS, post-surgical carotid restenosis, and medical therapy are the main topics, even with analysis of uncertainty areas for risk-benefit assessments in the individual patient (personalized medicine [PM]). CONCLUSIONS This GL updates on the main recommendations for the most appropriate diagnostic and medical-surgical management of patients with atherosclerotic carotid artery stenosis to prevent ischemic stroke. This GL also provides useful elements for the application of PM in good clinical practice.

Abstract
OBJECTIVE Shunt placement during carotid endarterectomy (CEA) is often advocated to protect the ischemic penumbra in patients with symptomatic carotid stenosis. This study assesses the effect of shunt placement on postoperative stroke risk in symptomatic patients undergoing CEA. METHODS We queried the American College of Surgeons National Surgical Quality Improvement Program database (2016-2019) for CEA cases with complete CEA procedure-targeted data. Symptomatic patients were identified as having a preoperative diagnosis of stroke on presentation (DS), transient ischemic attack (TIA), amaurosis fugax (AF), or temporary monocular blindness (TMB). DS patients were further analyzed according to the severity of their stroke based on their modified Rankin Scale (mRS). To better assess the effect of shunt placement on stroke rate, we compared cases of CEA with patch angioplasty technique, with and without the use of intraoperative shunt. Patients who underwent carotid eversion or primary closure were excluded. Baseline demographics and perioperative outcomes were compared using Chi-square and Mann-Whitney U test. Multivariate analysis was performed to identify independent risk factors for postoperative stroke and cranial nerve injury. RESULTS We identified 4,652 cases of CEA with patch angioplasty in symptomatic patients, including 1,889 (40.6%) with shunt placement and 2,763 (59.4%) without. Age, race, and sex distributions were similar for both procedures. Compared to patients without shunt, those with shunt had significantly higher rates of emergency (9.1% vs 7.0%, P = .010) and non-elective surgery (40.3% vs 37.2%, P = .035), general anesthesia (97.0% vs 86.3%, P < .001), and bleeding disorders (27.2% vs 22.7%, P < .001). Thirty-day incidence of postoperative stroke was similar between patients who had shunt placement (3.2%) and those who did not (2.6%) (P = .219). Additionally, subgroup analysis failed to show any benefit of shunting on postoperative stroke regardless of preoperative symptoms or neurologic disability. In contrast, shunt placement was associated with increased rate of cranial nerve injury (4.1% vs 2.4%, P = .001). Multivariate analysis revealed that non-elective surgery (OR 1.99, 95% CI 1.36-2.91, P < .001) and DS (vs TIA/AF/TMB) (OR 1.64, 95% CI 1.12-2.41, P = .012) were predictive of 30-day postoperative stroke. After adjusting for confounders, shunt placement had no effect on stroke risk at 30 days but remained an independent risk factor for cranial nerve injury (aOR 1.87, 95% CI 1.32-2.64, P < .001). CONCLUSIONS In symptomatic patients undergoing CEA with patch angioplasty, shunting is associated with increased risk of cranial nerve injury without reduction in postoperative stroke risk.

Abstract
BACKGROUND Temporary interruption of cerebral blood flow during carotid endarterectomy can be avoided by using a shunt across the clamped section of the carotid artery. The shunt may improve the outcome. This is an update of a Cochrane review originally published in 1996 and previously updated in 2002, 2009, and 2014. OBJECTIVES To assess the effect of routine versus selective or no shunting, and to assess the best method for selective shunting on death, stroke, and other complications in people undergoing carotid endarterectomy under general anaesthesia. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched April 2021), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2021, Issue 4), MEDLINE (1966 to April 2021), Embase (1980 to April 2021), and the Science Citation Index Expanded (SCI-EXPANDED) (1980 to April 2021). We also searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform, and handsearched relevant journals, conference proceedings, and reference lists. SELECTION CRITERIA Randomised and quasi-randomised trials of routine shunting compared with no shunting or selective shunting, and trials that compared different shunting policies in people undergoing carotid endarterectomy. DATA COLLECTION AND ANALYSIS Three independent review authors performed data extraction, selection, and analysis. A pooled Peto odds ratio (OR) and 95% confidence interval (CI) were computed for all outcomes of interest. Best and worse case scenarios were also calculated in case of unavailable data. Two authors independently assessed risk of bias, and quality of evidence using GRADE. MAIN RESULTS No new trials were found for this updated review. Thus, six trials involving 1270 participants are included in this latest review: three trials involving 686 participants compared routine shunting with no shunting, one trial involving 200 participants compared routine shunting with selective shunting, one trial involving 253 participants compared selective shunting with and without near-infrared refractory spectroscopy monitoring, and the other trial involving 131 participants compared shunting with a combination of electroencephalographic and carotid pressure measurement with shunting by carotid pressure measurement alone. Only three trials comparing routine shunting and no shunting were eligible for meta-analysis. Major findings of this comparison found that the routine shunting had less risk of stroke-related death within 30 days of surgery (best case) than no shunting (Peto odds ratio (OR) 0.13, 95% confidence interval (CI) 0.02 to 0.96, I2 not applicable, P = 0.05, low-quality evidence), the routine shunting group had a lower stroke rate within 24 hours of surgery (Peto odds ratio (OR) 0.15, 95% CI 0.03 to 0.78, I2 = not applicable, P = 0.02, low-quality evidence), and ipsilateral stroke within 30 days of surgery (best case) (Peto OR 0.41, 95% CI 0.18 to 0.97, I2 = 52%, P = 0.04, low-quality evidence) than the no shunting group. No difference was found between the groups in terms of postoperative neurological deficit between selective shunting with and without near-infrared refractory spectroscopy monitoring. However, this analysis was inadequately powered to reliably detect the effect. There was no difference between the risk of ipsilateral stroke in participants selected for shunting with the combination of electroencephalographic and carotid pressure assessment compared with pressure assessment alone, although again the data were limited. AUTHORS' CONCLUSIONS This review concluded that the data available were too limited to either support or refute the use of routine or selective shunting in carotid endarterectomy when performed under general anaesthesia. Large-scale randomised trials of routine shunting versus selective shunting are required. No method of monitoring in selective shunting has been shown to produce better outcomes.

Abstract
This study aimed to explore the role of clusterin released by platelet aggregation in restenosis after carotid endarterectomy. 35 patients who underwent carotid endarterectomy due to carotid artery stenosis were enrolled in this study. They were admitted to the Third Affiliated Hospital of Qiqihar Medical University from January 2018 to January 2019. All the patients were divided into two groups: the restenosis group and the nonrestenosis group, according to the follow-up results within 12 months. Peripheral blood was collected on the first day, 6 months, and 12 months after operation. The expression of CLU in serum of plasma and platelet culture medium was detected by an ELISA experiment. The vascular endothelial cells were cultured in vitro with 100 ng/mL of human recombinant CLU added to the medium. Cell proliferation, migration, and invasion were detected by CCK8, scratch, and Transwell invasion tests. The expression level of TLR3 and NF-κb p65 proteins in cells was detected by western blot. TLR3 knockout plasmids in vascular endothelial cell lines were transfected. Cell proliferation and migration were detected by CCK8 and the scratch assay. The CLU content in peripheral blood plasma and supernatant of platelet culture medium was significantly higher in the restenosis group than that of the control group (p=0.003) 6 months after operation (p=0.047) and 12 months after operation (p=0.011). When CLU was added to vascular endothelial cell culture medium, the proliferation and migration were significantly enhanced. The TLR3/NF-κb p65 protein expression level in cells also significantly increased. After the transfection of TLR3 knockout plasmids into vascular endothelial cell lines, CLU cannot promote the proliferation and migration of vascular endothelial cells. Platelet-released clusterin can induce vascular endothelial cell proliferation and migration by activating the TLR3/NF-kb p65 signaling pathway, leading to carotid artery restenosis after carotid endarterectomy.

Abstract
Atherosclerotic vascular disease is a leading cause of death worldwide. Atherosclerotic stenosis of the internal carotid or intracranial arteries causes up to 15% of strokes. Peripheral artery disease affects up to one in five people in the United States who are 60 years and older and nearly one-half of those who are 85 years and older. Renal artery stenosis may affect up to 5% of people with isolated hypertension and up to 40% of people with other atherosclerotic diseases. All patients with atherosclerotic vascular disease should receive a comprehensive program of guideline-directed medical therapy, including structured physical activity and lifestyle modification, an antiplatelet agent, a statin, antihypertensive therapy, and smoking cessation counseling. The U.S. Preventive Services Task Force recommends one-time screening for abdominal aortic aneurysm with ultrasonography in men 65 to 75 years of age who have smoked at least 100 cigarettes, but screening is not recommended for carotid, peripheral, and renal disease. Surgical revascularization decreases adverse outcomes and mortality in selected patients with advanced vascular disease. Endovascular repair has become more common for patients younger than 70 years because of decreased short-term mortality. Carotid revascularization with carotid endarterectomy or carotid artery stenting is recommended for symptomatic patients with greater than 50% internal carotid artery stenosis. Carotid artery stenting is preferred in patients with multiple comorbidities, tracheostomy, or previous neck radiation or dissection. In patients older than 70 years, carotid endarterectomy is associated with a lower risk of periprocedural stroke or death than carotid artery stenting. Revascularization is a reasonable treatment option for patients with lifestyle-limiting claudication and an inadequate response to guideline-directed therapies. Revascularization is indicated for patients with critical limb ischemia and is emergently indicated for acute limb ischemia. Renal artery revascularization offers no proven clinical benefit when added to optimal medical therapy.

Abstract
OBJECTIVE To analyze in-hospital and long-term results of eversion carotid endarterectomy (CEE), carotid endarterectomy with patch repair and carotid artery stenting (CAS) in patients with high bifurcation of common carotid artery. MATERIAL AND METHODS A retrospective multiple-center open study included 1983 patients who underwent internal carotid artery (ICA) repair for severe stenosis between 2010 and 2021. Three groups of patients were distinguished depending on revascularization option: group 1 (n=638) - eversion CEE; group 2 (n=351) - CEE with patch repair; group 3 (n=994) - CAS. RESULTS In-hospital postoperative mortality and incidence of stroke and myocardial infarction were similar. All bleedings (n=39) occurred after CEE. ICA thrombosis was diagnosed in groups 1 and 2 due to intimal detachment after insertion of temporary bypass tube. Incidence of laryngeal paresis, neuropathy of hypoglossal and glossopharyngeal nerves, Horner syndrome, damage to salivary glands was comparable in groups 1 and 2. Long-term mortality was the highest (n=10; 2.8%) after CEE with patch repair due to fatal stroke. In turn, the highest incidence of ICA restenosis and restenosis-induced ischemic stroke was observed after CEE with patch repair and CAS. CONCLUSION 1. Classical and eversion CEE in patients with high CCA bifurcation is followed by high in-hospital incidence of damage to cranial nerves and salivary glands, laryngeal paresis, Horner syndrome, bleeding and risk of ICA thrombosis. 2. In patients with high CCA bifurcation, CAS and CEE with patch repair are accompanied by high incidence of ICA restenosis, restenosis-induced stroke and mortality in long-term postoperative period. 3. Eversion CEE demonstrates the lowest rates of all adverse cardiovascular events in long-term follow-up period.

Abstract
OBJECTIVE To describe geometric models of carotid artery bifurcation and computer modeling of carotid endarterectomy (CEA) with patches of various configurations. MATERIAL AND METHODS The method was demonstrated on a reconstructed model of intact vessel based on preoperative CT of the affected vessel in a certain patient. Blood flow is modeled by computational fluid dynamics using Doppler ultrasound data. Risk factors were assessed considering hemodynamic parameters of vascular wall associated with WSS. RESULTS We studied hemodynamic results of 10 virtual CEA with patches of various shapes on the example of a reconstructed intact artery in a particular patient. Patch implantation is aimed at prevention of carotid artery narrowing since simple suture without a patch can reduce circumference of the artery by 4-5 mm. This result adversely affects blood flow. On the other hand, too wide a patch creates aneurysm-like deformation of internal carotid artery bulb. It is not optimal due to a large recirculation zone. It was found that patch width approximately equal to 3 mm ensures an optimal hemodynamic result. Deviations from this median value, both upward and downward, impair hemodynamics while the absence of a patch results the worst result. CONCLUSION The proposed computer modeling technique is able to provide a personalized patch selection for CEA with low risk of restenosis in long-term follow-up period.

Abstract
Background There have been inconsistent results regarding the use of carotid artery endarterectomy (CEA) versus carotid artery stenting (CAS) for contralateral carotid occlusion (CCO). This study aimed to determine the optimal revascularization technique for patients with CCO. Methods We systematically searched the PubMed, Embase, and Cochrane Library databases to identify eligible studies published from inception to January 2, 2021. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to calculate pooled effect estimates using a random-effects model. Sensitivity, subgroup, and publication bias analyses were also performed. Results Six studies involving 6,953 patients were selected for inclusion in this meta-analysis. Our results showed that while CEA was not associated with an increased risk of stroke compared to CAS (OR: 1.07; 95% CI: 0.75–1.51; P = 0.713), CEA was associated with a reduced risk of death compared to CAS (OR: 0.45; 95% CI: 0.29–0.70; P < 0.001). Furthermore, there were no significant differences between CEA and CAS for the risks of myocardial infarction (OR: 1.38; 95% CI: 0.73–2.62; P = 0.319) or major adverse cardiovascular events (OR: 1.03; 95% CI: 0.56–1.88; P = 0.926). Finally, the risk of myocardial infarction for CEA versus CAS was affected by disease status, while the risk of major adverse cardiovascular events was affected by the proportions of patients with male gender, coronary artery disease, and current or prior smoking. Conclusion This study found that CEA and CAS resulted in similar outcomes for patients with CCO, while the risk of death was reduced in patients treated with CEA. Further high-level evidence should be collected to verify the results of this study.

Abstract
BACKGROUND Extracranial carotid artery stenosis is the major cause of stroke, which can lead to disability and mortality. Carotid endarterectomy (CEA) with carotid patch angioplasty is the most popular technique for reducing the risk of stroke. Patch material may be made from an autologous vein, bovine pericardium, or synthetic material including polytetrafluoroethylene (PTFE), Dacron, polyurethane, and polyester. This is an update of a review that was first published in 1996 and was last updated in 2010. OBJECTIVES To assess the safety and efficacy of different types of patch materials used in carotid patch angioplasty. The primary hypothesis was that a synthetic material was associated with lower risk of patch rupture versus venous patches, but that venous patches were associated with lower risk of perioperative stroke and early or late infection, or both. SEARCH METHODS We searched the Cochrane Stroke Group trials register (last searched 25 May 2020); the Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 4), in the Cochrane Library; MEDLINE (1966 to 25 May 2020); Embase (1980 to 25 May 2020); the Index to Scientific and Technical Proceedings (1980 to 2019); the Web of Science Core Collection; ClinicalTrials.gov; and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) portal. We handsearched relevant journals and conference proceedings, checked reference lists, and contacted experts in the field. SELECTION CRITERIA Randomised and quasi-randomised trials (RCTs) comparing one type of carotid patch with another for CEA. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility, risk of bias, and trial quality; extracted data; and determined the quality of evidence using the GRADE approach. Outcomes, for example, perioperative ipsilateral stroke and long-term ipsilateral stroke (at least one year), were collected and analysed. MAIN RESULTS We included 14 trials involving a total of 2278 CEAs with patch closure operations: seven trials compared vein closure with PTFE closure, five compared Dacron grafts with other synthetic materials, and two compared bovine pericardium with other synthetic materials. In most trials, a patient could be randomised twice and could have each carotid artery randomised to different treatment groups. Synthetic patch compared with vein patch angioplasty Vein patch may have little to no difference in effect on perioperative ipsilateral stroke between synthetic versus vein materials, but the evidence is very uncertain (odds ratio (OR) 2.05, 95% confidence interval (CI) 0.66 to 6.38; 5 studies, 797 participants; very low-quality evidence). Vein patch may have little to no difference in effect on long-term ipsilateral stroke between synthetic versus vein materials, but the evidence is very uncertain (OR 1.45, 95% CI 0.69 to 3.07; P = 0.33; 4 studies, 776 participants; very low-quality evidence). Vein patch may increase pseudoaneurysm formation when compared with synthetic patch, but the evidence is very uncertain (OR 0.09, 95% CI 0.02 to 0.49; 4 studies, 776 participants; very low-quality evidence). However, the numbers involved were small. Dacron patch compared with other synthetic patch angioplasty Dacron versus PTFE patch materials PTFE patch may reduce the risk of perioperative ipsilateral stroke (OR 3.35, 95% CI 0.19 to 59.06; 2 studies, 400 participants; very low-quality evidence). PTFE patch may reduce the risk of long-term ipsilateral stroke (OR 1.52, 95% CI 0.25 to 9.27; 1 study, 200 participants; very low-quality evidence). Dacron may result in an increase in perioperative combined stroke and transient ischaemic attack (TIA) (OR 4.41 95% CI 1.20 to 16.14; 1 study, 200 participants; low-quality evidence) when compared with PTFE. Early arterial re-stenosis or occlusion (within 30 days) was also higher for Dacron patches. During follow-up for longer than one year, more 'any strokes' (OR 10.58, 95% CI 1.34 to 83.43; 2 studies, 304 participants; low-quality evidence) and stroke/death (OR 6.06, 95% CI 1.31 to 28.07; 1 study, 200 participants; low-quality evidence) were reported with Dacron patch closure, although numbers of outcome events were small. Dacron patch may increase the risk of re-stenosis when compared with other synthetic materials (especially with PTFE), but the evidence is very uncertain (OR 3.73, 95% CI 0.71 to 19.65; 3 studies, 490 participants; low-quality evidence). Bovine pericardium patch compared with other synthetic patch angioplasty Bovine pericardium versus PTFE patch materials Evidence suggests that bovine pericardium patch results in a reduction in long-term ipsilateral stroke (OR 4.17, 95% CI 0.46 to 38.02; 1 study, 195 participants; low-quality evidence). Bovine pericardial patch may reduce the risk of perioperative fatal stroke, death, and infection compared to synthetic material (OR 5.16, 95% CI 0.24 to 108.83; 2 studies, 290 participants; low-quality evidence for PTFE, and low-quality evidence for Dacron; OR 4.39, 95% CI 0.48 to 39.95; 2 studies, 290 participants; low-quality evidence for PTFE, and low-quality evidence for Dacron; OR 7.30, 95% CI 0.37 to 143.16; 1 study, 195 participants; low-quality evidence, respectively), but the numbers of outcomes were small. The evidence is very uncertain about effects of the patch on infection outcomes. AUTHORS' CONCLUSIONS The number of outcome events is too small to allow conclusions, and more trial data are required to establish whether any differences do exist. Nevertheless, there is little to no difference in effect on perioperative and long-term ipsilateral stroke between vein and any synthetic patch material. Some evidence indicates that other synthetic patches (e.g. PTFE) may be superior to Dacron grafts in terms of perioperative stroke and TIA rates, and both early and late arterial re-stenosis and occlusion. Pseudoaneurysm formation may be more common after use of a vein patch than after use of a synthetic patch. Bovine pericardial patch, which is an acellular xenograft material, may reduce the risk of perioperative fatal stroke, death, and infection compared to other synthetic patches. Further large RCTs are required before definitive conclusions can be reached.

Abstract
IMPORTANCE Transcarotid artery revascularization (TCAR) may serve as a safer alternative to carotid endarterectomy (CEA) for certain patients with carotid artery stenosis. OBJECTIVE To determine the center-level association of TCAR adoption with overall perioperative outcomes for TCAR and CEA combined at centers performing both procedures. DESIGN, SETTING, AND PARTICIPANTS This comparative-effectiveness research was conducted with a difference-in-difference analysis using retrospective data from 2015 to 2019 from the Vascular Quality Initiative registry, a consortium of more than 400 centers in North America. Included patients underwent TCAR or CEA for carotid artery stenosis. Patients who underwent transfemoral carotid stenting were excluded. Data were analyzed from December 2019 through August 2020. EXPOSURES Center-level adoption of TCAR vs not. MAIN OUTCOMES AND MEASURES The rate of major adverse cardiovascular events (MACE), a composite of in-hospital stroke, myocardial infarction, or death at 30 days, was measured. RESULTS Among 86 027 patients who underwent revascularization for carotid artery stenosis, 7664 patients (8.9%) underwent TCAR (mean [SD] age, 73.1 [9.6] years; 2788 [36.4%] women; 6938 White patients [90.6%]; and 3741 patients with symptoms [48.8%]) and 78 363 patients (91.1%) underwent CEA (mean [SD] age, 70.6 [9.2] years; 30 928 [39.5%] women; 70 663 White patients [90.2%]; and 37 883 patients with symptoms [48.3%]). The number of centers performing both TCAR and CEA increased from 15 centers in 2015 to 247 centers in 2019, a more than 16-fold increase. The proportion of all carotid procedures that were TCARs increased from 90 of 12 276 (0.7%) in 2015 to 2718 of 15 956 (17.0%) in 2019, a 24-fold increase. Overall, the crude rate of MACE was similar for TCAR and CEA (178 patients [2.3%] after TCAR vs 1842 patients [2.4%] after CEA; P = .91). However, the rate of MACE over time decreased for CEA (406 of 16 404 patients [2.5%] in 2015 vs 189 of 10 097 patients [1.9%] in 2019; P for trend < .001). The rate of MACE over time decreased for TCAR as well, but the change was not statistically significant (4 of 128 patients [3.1%] in 2016 vs 59 of 2718 patients [2.2%] in 2019; P for trend = .07). Difference-in-difference analysis demonstrated that centers that adopted TCAR had a 10% decrease in the likelihood of MACE at 12 months after TCAR adoption vs if those centers had continued to perform CEA alone (odds ratio, 0.90; 95% CI, 0.81-0.99; P = .04). CONCLUSIONS AND RELEVANCE This comparative-effectiveness study of a cohort of patients who underwent TCAR or CEA found that availability of TCAR at a hospital was associated with a decrease in the likelihood of perioperative MACE after carotid revascularization.

Abstract
DESIGN A systematic document retrieval of studies published in the past 10 years reporting periprocedural stroke/mortality/MI after carotid endarterectomy (CEA) related to the time between CEA and qualifying neurological symptoms. The application database has "PubMed, EMbase and Cochrane databases." RevMan5.3 software provided by the Cochrane collaboration was used for meta-analysis. RESULTS A systematic literature search was conducted in databases. A total of 10 articles were included in this study. They were divided into early CEA and delayed CEA with operation within 48 h, 1 w, or 2 w after onset of neurological symptoms. Incidence of the postoperative stroke in patients undergoing delayed CEA (≥48 h) was significantly higher than patients with delayed CEA (<48 h) (OR = 2.14, 95% CI: 1.43-3.21, P = 0.0002). The postoperative mortality of patients after delayed CEA (≥48 h) was significantly higher than patients after early CEA (<48 h) (OR = 1.35, 95% CI: 1.06-1.71, P = 0.02). The risk of postoperative mortality of patients treated with delayed CEA (≥7 d) was significantly higher than patients after the early CEA group (<7 d) (OR = 1.69, 95% CI: 1.21-2.32, P = 0.001). CONCLUSION Early CEA is safe and effective for a part of patients with symptomatic carotid stenosis, but a comprehensive preoperative evaluation of patients with carotid stenosis must be performed.

Abstract
BACKGROUND AND PURPOSE CREST (Carotid Revascularization Endarterectomy Versus Stenting Trial) reported a higher periprocedural risk for any stroke, death, or myocardial infarction for women randomized to carotid artery stenting (CAS) compared with women randomized to carotid endarterectomy (CEA). No difference in risk by treatment was detected for women relative to men in the 4-year primary outcome. We aimed to conduct a pooled analysis among symptomatic patients in large randomized trials to provide more precise estimates of sex differences in the CAS-to-CEA risk for any stroke or death during the 120-day periprocedural period and ipsilateral stroke thereafter. METHODS Data from the Carotid Stenosis Trialists' Collaboration included outcomes from symptomatic patients in EVA-3S (Endarterectomy Versus Angioplasty in Patients With Symptomatic Severe Carotid Stenosis), SPACE (Stent-Protected Angioplasty Versus Carotid Endarterectomy in Symptomatic Patients), ICSS (International Carotid Stenting Study), and CREST. The primary outcome was any stroke or death within 120 days after randomization and ipsilateral stroke thereafter. Event rates and relative risks were estimated using Poisson regression; effect modification by sex was assessed with a sex-by-treatment-by-trial interaction term, with significant interaction defined a priori as P≤0.10. RESULTS Over a median 2.7 years of follow-up, 433 outcomes occurred in 3317 men and 1437 women. The CAS-to-CEA relative risk of the primary outcome was significantly lower for women compared with men in 1 trial, nominally lower in another, and nominally higher in the other two. The sex-by-treatment-by-trial interaction term was significant (P=0.065), indicating heterogeneity among trials. Contributors to this heterogeneity are primarily differences in periprocedural period. When the trials are nevertheless pooled, there were no significant sex differences in risk in any follow-up period. CONCLUSIONS There were significant differences between trials in the magnitude of sex differences in treatment effect (CAS-to-CEA relative risk), indicating pooling data from these trials to estimate sex differences might not be valid. Whether sex is acting as an effect modifier of the CAS-to-CEA treatment effect in symptomatic patients remains uncertain.

Abstract
BACKGROUND Carotid artery stenosis is closely related to cognitive dysfunction, in which decreased cerebral perfusion is one of the important factors. Both carotid artery stent implantation and carotid endarterectomy can relieve stenosis and increase cerebral perfusion. In this study, we aimed to compare the effects of carotid artery stent implantation and endarterectomy on cognitive function. METHODS A total of 98 patients with carotid artery stenosis hospitalized in our hospital from July 2015 to January 2017 were included. Among them, 50 cases underwent carotid artery stent implantation treatment as stent implantation group (CAS group), and 48 cases underwent carotid artery endarterectomy treatment as carotid endarterectomy group (CEA group). Using the Mini-Mental State Examination Scale (MMSE Scale) and the Montreal Cognitive Assessment Scale (MoCA Scale), the cognitive function scores of the two groups of patients before and after 3 and 6 months of operation were measured, and the patients were also measured before and after surgery, after the serum NSE, hs-CRP content. RESULTS The serum NSE, hs-CRP content, MMSE score, and MoCA score of the two groups before treatment were not statistically significant (P > 0.05). The MMSE score and MoCA score of the two groups of patients before treatment were lower than the normal value, suggesting carotid artery stenosis combined with different degrees of cognitive dysfunction. Carotid artery stenosis is different, and patients' cognitive function is also different. The MMSE score and MoCA score of the two groups at 3 and 6 months after operation were higher than before treatment, and there was a statistically significant difference between 6 and 3 months after operation (P < 0.05), but at each time There was no statistically significant difference between the two groups (P > 0.05). The NSE content of the two groups of patients after operation decreased compared with that before treatment, and the decrease in 6 months after operation was more obvious than that in March (P < 0.05). However, the difference between the two groups at each time point was not statistically significant (P > 0.05). The content of hs-CRP in the two groups of patients was higher than that before the operation, and the CAS group was significantly higher than the CEA group; the difference was statistically significant (P < 0.05). CONCLUSION Carotid artery stent and carotid endarterectomy are effective in improving the cognitive function of patients with carotid stenosis, but there is no significant difference between the two.

Abstract
Stroke is a major cause of death and disability globally. Diagnosis depends on clinical features and brain imaging to differentiate between ischaemic stroke and intracerebral haemorrhage. Non-contrast CT can exclude haemorrhage, but the addition of CT perfusion imaging and angiography allows a positive diagnosis of ischaemic stroke versus mimics and can identify a large vessel occlusion target for endovascular thrombectomy. Management of ischaemic stroke has greatly advanced, with rapid reperfusion by use of intravenous thrombolysis and endovascular thrombectomy shown to reduce disability. These therapies can now be applied in selected patients who present late to medical care if there is imaging evidence of salvageable brain tissue. Both haemostatic agents and surgical interventions are investigational for intracerebral haemorrhage. Prevention of recurrent stroke requires an understanding of the mechanism of stroke to target interventions, such as carotid endarterectomy, anticoagulation for atrial fibrillation, and patent foramen ovale closure. However, interventions such as lowering blood pressure, smoking cessation, and lifestyle optimisation are common to all stroke subtypes.

Abstract
INTRODUCTION Traditional carotid endarterectomy is considered to be the standard technique for prevention of a new stroke in patients with a symptomatic carotid stenosis. Use of patch angioplasty to restore the arterial wall after longitudinal endarterectomy is, to date, not unequivocally proven to be superior to eversion technique. A systematic review is needed for evaluation of benefits and harms of the eversion technique versus the traditional endarterectomy with patch angioplasty in patients with symptomatic carotid stenosis. METHODS AND OUTCOMES The review will be conducted according to this protocol following the recommendations of the 'Cochrane Handbook for Systematic Reviews' and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Randomised clinical trials comparing eversion technique versus endarterectomy with patch angioplasty in patients with a symptomatic stenosis of the internal carotid artery will be included. Primary outcomes are all-cause mortality rate, health-related quality of life and serious adverse events. Secondary outcomes are 30-day stroke and mortality rate, symptomatic arterial restenosis or occlusion and non-serious adverse events. The databases Cochrane Central Register of Controlled Trials, PubMed/MEDLINE and EMBASE will be searched (November 2019). We will primarily base our conclusions on meta-analyses of trials with overall low-risk of bias. We will use trial sequential analysis to assist the evaluation of imprecision in Grading of Recommendations, Assessment, Development and Evaluation. However, if pooled point estimates of all trials are similar to pooled point estimates of trials with overall low risk of bias and there is lack of a statistical significant interaction between estimates from trials with overall high risk of bias and trials with overall low risk of bias we will consider the trial sequential analysis adjusted precision of the estimate achieved in all trials as the result of our meta-analyses. ETHICS AND DISSEMINATION The proposed systematic review will collect and analyse data from published studies, therefore, ethical approval is not required. The results of the review will be disseminated by publication in a peer-review journal and submitted for presentation at conferences. PROSPERO REGISTRATION NUMBER CRD42019119361.

Abstract
OBJECTIVE To identify the advantages and disadvantages of different approaches for carotid endarterectomy (conventional, longitudinal and transverse incision). MATERIAL AND METHODS There were 58 patients who underwent carotid endarterectomy. Patients were divided into 2 groups depending on surgical approach. Group 1 (n=37) - minimal skin incision (less than 5 cm). There were subgroup 1A (transverse minimal skin incision along the natural skin wrinkle, n=17) and subgroup 1B (longitudinal minimal skin incision, n=20). Group 2 (n=21) - conventional longitudinal incision. Surgical outcomes were analyzed after 1 month and 1 year. End-points were mortality, stroke, TIA, cranial nerve neuropathy. Cosmetic effect was evaluated using POSAS scale (Patient and Observer Scar Assessment Scale, Draaijers, 2004). RESULTS Mortality, stroke and TIA were absent after 1 month. Cranial nerve neuropathy was not observed in subgroup 1A and diagnosed in 2 (10%) patients of subgroup 1B and 6 (28.5%) patients of group 2. Cosmetic effect: subgroup 1A - 48.4±9.5 scores, subgroup 1B - 52.4±9.2, group 2 - 63.1±11.1 (p<0.05). The outcomes after 12 months: mortality was absent in subgroups 1A and 1B, 2 patients died in group 2 from AMI. Stroke was absent in subgroups 1A and 1B, group 2 - 1 patient. Cranial nerve neuropathy was absent in 1A and 1B subgroups and diagnosed in 4 (21%) patients of group 2. Cosmetic effect: subgroup 1A - 37.2 scores, subgroup 1B - 40.0 scores, group 2 - 55.1 scores. Physical component of QOL: subgroup 1A - 51.63±6.31 scores, subgroup 1B - 46.01±7.53 scores, group 2 - 38.85±5.33 scores. Psychological component of QOL: subgroup 1A - 49.64±6.72 scores, subgroup 1B - 45.68±5.63 scores, group 2 - 48.6±7.36 scores (p<0.05). CONCLUSION Transverse minimal skin incision for carotid endarterectomy is a safe alternative to classic longitudinal incision and reduces the risk of postoperative complications with significant cosmetic effect.

Abstract
Background and Purpose- This analysis was performed to assess the association between perioperative and clinical variables and the 30-day risk of stroke or death after carotid endarterectomy for symptomatic carotid stenosis. Methods- Individual patient-level data from the 5 largest randomized controlled carotid trials were pooled in the Carotid Stenosis Trialists' Collaboration database. A total of 4181 patients who received carotid endarterectomy for symptomatic stenosis per protocol were included. Determinants of outcome included carotid endarterectomy technique, type of anesthesia, intraoperative neurophysiological monitoring, shunting, antiplatelet medication, and clinical variables. Stroke or death within 30 days after carotid endarterectomy was the primary outcome. Adjusted risk ratios (aRRs) were estimated in multilevel multivariable analyses using a Poisson regression model. Results- Mean age was 69.5±9.2 years (70.7% men). The 30-day stroke or death rate was 4.3%. In the multivariable regression analysis, local anesthesia was associated with a lower primary outcome rate (versus general anesthesia; aRR, 0.70 [95% CI, 0.50-0.99]). Shunting (aRR, 1.43 [95% CI, 1.05-1.95]), a contralateral high-grade carotid stenosis or occlusion (aRR, 1.58 [95% CI, 1.02-2.47]), and a more severe neurological deficit (mRS, 3-5 versus 0-2: aRR, 2.51 [95% CI, 1.30-4.83]) were associated with higher primary outcome rates. None of the other characteristics were significantly associated with the perioperative stroke or death risk. Conclusions- The current results indicate lower perioperative stroke or death rates in patients operated upon under local anesthesia, whereas a more severe neurological deficit and a contralateral high-grade carotid stenosis or occlusion were identified as potential risk factors. Despite a possible selection bias and patients not having been randomized, these findings might be useful to guide surgeons and anesthetists when treating patients with symptomatic carotid disease.

Abstract
INTRODUCTION Carotid intervention in the form of endarterectomy or stenting is the current standard of care for the majority of patients with symptomatic high-grade carotid stenosis. However, some randomised controlled trials (RCT) have demonstrated that women benefited significantly less from intervention than men. It is unclear if this is a true phenomenon or a study sampling artefact, as women were severely under-represented in all RCTs of carotid revascularisation. A systematic review is needed to summarise the existing data and to answer the question of whether a women-only trial for symptomatic patients with ipsilateral carotid stenosis is scientifically necessary and ethically permissible. METHODS AND ANALYSIS We will systematically search Medline, Embase, PubMed and the Cochrane libraries for all studies with data from RCTs that included women and compared either endarterectomy with stenting or revascularisation (by means of endarterectomy or stenting) with medical therapy in patients with symptomatic carotid stenosis. Search dates will be restricted to 1991-2018. Two reviewers will conduct screening search results, study selection, data extraction and quality assessment. We will include all studies reporting outcomes of interest. Planned subgroup analysis based on revascularisation technique, degree of stenosis and timing of intervention from the index event will be conducted with enough data. ETHICS AND DISSEMINATION This research is exempt of ethics approval as no primary data will be collected. The results will be published in peer-reviewed journals and disseminated through national and international-level conferences and scientific meetings. The result of this comprehensive review will provide useful information on whether further RCTs are required to study a women-only population with symptomatic carotid disease. PROSPERO REGISTRATION NUMBER CRD42019134967.
