Abstract
Open surgical repair remains the gold standard for treatment for aortic arch diseases, but these operations can be associated with wide heterogeneity in outcomes and significant morbidity and mortality, particularly in elderly patients with severe comorbidities or those who had prior arch procedures via median sternotomy. Endovascular repair has been introduced as a less invasive alternative to reduce morbidity and mortality associated with open surgical repair. The technique evolved with new device designs using up to three inner branches for incorporation of the supra-aortic trunks. This manuscript summarizes technical tips and clinical experience with the triple inner arch branch stent graft for total endovascular repair of aortic arch pathologies.

Abstract
Thoracic endovascular aortic repair (TEVAR) has been widely accepted as a treatment option in patients with thoracic aortic aneurysms and dissections who have suitable anatomy. It is estimated that up to 60% of patients treated by TEVAR require extension of the repair into the distal aortic arch across Ishimaru zone 2. In these patients, coverage of the left subclavian artery (LSA) without revascularization has been associated with increased risk of arm ischemia, stroke, and spinal cord injury. The Gore Thoracic Branch Endoprosthesis (TBE, WL Gore, Flagstaff, AZ, USA) is the first off-the-shelf thoracic branch stent-graft approved by the Federal Drug Administration for treatment of distal aortic arch lesions requiring extension of the proximal seal into zone 2. This article summarizes the technical pitfalls and clinical outcomes of the TBE® device in zone 2.

Abstract
Endovascular aortic arch repair has been widely used in select patients who are considered high risk for open surgical repair and have suitable anatomy. The anatomical challenges of placement of stent-grafts in the ascending aorta are many, including the curved configuration, short landing zone, proximity to the aortic valve and coronary arteries and need to incorporate the supra-aortic trunks. Stent-graft designs with fenestrations and/or directional branches are applicable to patients who have suitable landing zones in the aorta and supra-aortic trunks, adequate access and absence of significant atheromatous debris. These devices include single and multibranch concepts, which are used in combination or not with cervical debranching procedures. This article summarizes the most commonly used anatomical criterion with currently utilized arch branch stent-grafts.

Abstract
OBJECTIVES Carbon dioxide (CO2) angiography for endovascular aortic repair (CO2-EVAR) is used to treat abdominal aortic aneurysms (AAAs), especially in patients with chronic kidney disease or allergy to iodinated contrast medium (ICM). However, some technical issues regarding the visualization of the lowest renal artery (LoRA) and the best quality image through angiographies performed from pigtail or introducer sheath are still unsolved. The aim of this study was to analyze different steps of CO2-EVAR to create an operative standardized protocol. METHODS Patients undergoing CO2-EVAR were prospectively enrolled in five European centers from 2019 to 2021. CO2-EVAR was performed using an automated injector (pressure, 600 mmHg; volume, 100 cc); a small amount of ICM was injected in case of difficulty in LoRA visualization. LoRA visualization and image quality (1 = low, 2 = sufficient, 3 = good, 4 = excellent) were analyzed at different procedure steps: preoperative CO2 angiography from pigtail and femoral introducer sheath (first step), angiographies from pigtail at 0%, 50%, and 100% of proximal main body deployment (second step), contralateral hypogastric artery (CHA) visualization with CO2 injection from femoral introducer sheath (third step), and completion angiogram from pigtail and femoral introducer sheath (fourth step). Intraoperative and postoperative CO2-related adverse events were also evaluated. χ2 and Wilcoxon tests were used for statistical analysis. RESULTS In the considered period, 65 patients undergoing CO2-EVAR were enrolled (55/65 [84.5%] male; median age, 75 years [interquartile range (IQR), 11.5 years]). The median ICM injected was 17 cc (IQR, 51 cc); 19 (29.2%) of 65 procedures were performed with 0 cc ICM. Fifty-five (84.2%) of 65 patients underwent general anesthesia. In the first step, median image quality was significantly higher with CO2 injected from femoral introducer (pigtail, 2 [IQR, 3] vs introducer, 3 [IQR, 3]; P = .008). In the second step, LoRA was more frequently detected at 50% (93% vs 73.2%; P = .002) and 100% (94.1% vs 78.4%; P = .01) of proximal main body deployment compared with first angiography from pigtail; similarly, image quality was significantly higher at 50% (3 [IQR, 3] vs 2 [IQR, 3]; P ≤ .001) and 100% (4 [IQR, 3] vs 2 [IQR, 3]; P = .001) of proximal main body deployment. CHA was detected in 93% cases (third step). The mean image quality was significantly higher when final angiogram (fourth step) was performed from introducer (pigtail, 2.6 ± 1.1 vs introducer, 3.1 ± 0.9; P ≤ .001). The intraoperative (7.7%) and postoperative (12.5%) adverse events (pain, vomiting, diarrhea) were all transient and clinically mild. CONCLUSIONS Preimplant CO2 angiography should be performed from femoral introducer sheath. Gas flow impediment created by proximal main body deployment can improve image quality and LoRA visualization with CO2. CHA can be satisfactorily visualized with CO2 alone. Completion CO2 angiogram should be performed from femoral introducer sheath. This operative protocol allows performance of CO2-EVAR with 0 cc or minimal ICM, with a low rate of mild temporary complications.

Abstract
Intramural hematoma (IMH) is one of the acute aortic syndromes along with acute aortic dissection and penetrating aortic ulcer. The three conditions can occur alone or in combination with overlapping presentation. Medical, open surgical, and endovascular treatment is tailored depending on clinical presentation, timing, and location within the aorta. Among patients who present with acute IMH affecting the ascending aorta (Type A), urgent open surgical repair is considered the primary line of treatment in patients who are suitable candidates and unstable. The management of IMH in the descending aorta and aortic arch (Type B) is similar to that applied to treat acute dissections in the same segment. Medical treatment with sequential imaging is recommended in patients with uncomplicated course, and endovascular repair is indicated in patients with rupture, persistent pain, end-organ ischemia, or rapid aortic enlargement. This review discusses the ideal timing for treatment of IMH.

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 To report the characteristics of the prospective observational cohort study "Carotid Asymptomatic Stenosis (CARAS)", including patients with asymptomatic carotid stenosis under medical treatment and their first year of follow-up, in order to estimate the risk of cerebral ischemic events. METHODS This is a prospective observational cohort study of CARAS>60% (Nascet criteria) patients, identified in a single duplex-ultrasonography (DUS) vascular laboratory (trail registration N: NCT04825080). Patient's enrollment started in January 2019 and ended in March 2020 with the follow-up conclusion scheduled in December 2025. The aimed sample size was calculated at 300 patients for a 5-year follow-up. The primary outcome were the incidence of ipsilateral neurologic ischemic events (stokes and transient ischemic attacks [TIA]), plaque progression rate, and survival. The follow-up was scheduled at six-month intervals for clinical visit and annually for DUS examination. RESULTS a total of 307 patients completed the first follow-up year. The mean age was 81±4 years, 55% were male. Contralateral stenosis >60% was present in 90 (29%) patients. Antiplatelet therapy and statins adherence was 80% and 88%, respectively. During the first year, 3 ispilateral strokes (1%) and 4 TIAs (1.3%) occurred, for a total of 2.3% ipsilateral ischemic events. During the first year, 43 (14%) plaques had a stenosis progression, which was correlated with the occurrence of neurological events (9.3% vs. 1.1%, P=.001, OR: 8.9; 95%CI: 1.9-41); 6 deaths (2%) occurred in the same period. CONCLUSION the preliminary one-year results of this prospective study suggest that the overall rate of any ipsilateral ischemic event, and specifically ipsilateral strokes, correlates with plaque progression.

Abstract
BACKGROUND AND AIMS In order to systematically review the latest evidence on anesthesia, intraoperative neurologic monitoring, postoperative heparin reversal, and postoperative blood pressure management for carotid endarterectomy. The present review is based on a single chapter of the Italian Health Institute Guidelines for diagnosis and treatment of extracranial carotid stenosis and stroke prevention. METHODS AND RESULTS A systematic article review focused on the previously cited topics published between January 2016 and October 2020 has been performed; we looked for both primary and secondary studies in the extensive archive of Medline/PubMed and Cochrane library databases. We selected 14 systematic reviews and meta-analyses, 13 randomized controlled trials, 8 observational studies, and 1 narrative review. Based on this analysis, syntheses of the available evidence were shared and recommendations were indicated complying with the GRADE-SIGN version methodology. CONCLUSIONS From this up-to-date analysis, it has emerged that any type of anesthesia and neurological monitoring method is related to a better outcome after carotid endarterectomy. In addition, insufficient evidence was found to justify reversal or no-reversal of heparin at the end of surgery. Furthermore, despite a low evidence level, a suggestion for blood pressure monitoring in the postoperative period was formulated.

Abstract
INTRODUCTION The aim of the study is to report a single-center experience with the Gore Excluder conformable endograft with active control system (CEXC Device, W.L. Gore and Associates, Flagstaff, AZ, USA) in abdominal aortic aneurysms (AAAs) with severe infrarenal neck angulation. METHODS All patients underwent EVAR with CEXC Device between September 2018 and 2020, were prospectively enrolled, and retrospectively analyzed. Anatomical details of the proximal aortic neck were evaluated. Early endpoints were the use of repositionability and angulation system, intraoperative unplanned cuff, technical success (TS), 30-day morbidity/mortality, and reintervention. Follow-up endpoints were type-I endoleaks, endograft migration, aortic neck dilatation, aneurismal sac shrinkage, survival (S), and freedom from reintervention (FFR). RESULTS Twenty-five patients were enrolled (median age: 80 [range = 60-90] years, median AAA diameter: 60 [range = 52-90] mm). All patients had severe infrarenal neck angulation (beta angle ≧ 60°), and 11 (44%) of those had neck beta angle ≧ 90°. Median infrarenal neck angle, length, and diameter were 70° (range = 60°-90°), 22 (range = 13-42) mm and 22 (range = 18-31) mm, respectively. Endograft repositioning system was employed in 15 (60%) cases and the median number of repositioning maneuvers was 1 (range:0-4). Active angulation system was used in 17 (68%) patients. The median proximal diameter of the main-body and oversize were 28 (range = 23-36) mm and 28% (range = 21%-38%), respectively. Proximal cuff was positioned in 1 (4%) patient. Technical success was achieved in all cases. Intraoperative and perioperative morbidity and mortality were 12% and 0%, respectively. Perioperative type-I/III and II endoleaks were observed in 0 and 4 (16%) patients, respectively. The median follow-up was 12 months (range: 3-30). One patient died at 12-month for AAA-unrelated causes. Abdominal aortic aneurysm-sac shrinkage and stability were observed in 9 (36%) and 15 (60%) cases, respectively. No type-I/III endoleak and reintervention occurred during the follow-up. One persistent type-II endoleak was observed. Estimated survival at 24 months was 92%. CONCLUSION According to the present data, the CEXC Device allows an excellent rate of TS in severe angulated aortic neck. This preliminary data, could increase the rate of patients eligible for EVAR.

Abstract
INTRODUCTION Different models have been proposed for the prediction of the risk/benefit ratio of surgery in patients with carotid atheromasic disease, mainly based on clinical patients' characteristics and risk factors, but no definite biological markers predictive of plaque instability and disease evolution have emerged so far, able to help the surgeon in the choice and timing of treatment. The main purpose of the present study was to assess the role of the polymorphism for genes commonly implicated in cell proliferation and neoangiogenesis in the clinical and histopathological carotid plaque vulnerability. MATERIALS AND METHODS We retrospectively studied 29 consecutive patients who underwent carotid endarterectomy in 6 months. All histological variables were collected, as well as patients' cardiovascular risk factors, clinical presentation, and brain computed tomography (CT) for the presence of ischemic lesions. Next-Generation Sequencing (NGS) was performed on 10-µm FFPE sections by means of a multi-gene panel used for sequencing 343 amplicons in 28 genes. RESULTS Among the gene variants observed, the polymorphism p.(Gln787=) in the EGFR gene was inversely correlated with intraplaque hemorrhage (p = 0.014), but also with the presence of ischemic brain lesions at CT (p = 0.001). Also p.(Gly105=) polymorphism in the IDH1 gene was inversely correlated with the presence of ischemic brain lesions (p = 0.038). CONCLUSIONS The variant p.(Gln787=) in the EGFR gene seems to play a role in plaque stability in patients with carotid atheromasic disease, on both histopathological and clinical grounds, probably acting on plaque matrix remodeling. This can open new scenarios on the pre-surgical management of these patients.

Abstract
BACKGROUND Contrast induced nephropathy occurs in up to 7.5% of cases in endovascular aortic repair (EVAR). Carbon dioxide (CO2) has been proposed as an alternative agent to iodinated contrast medium (ICM); however, specific protocols are not universally adopted, and the visualization of the renal arteries may be suboptimal in some cases. The aim of this study was to analyze our CO2-EVAR experience with automatic injections, in order to identify the anatomical characteristics associated with the best visualization of all the aortic vessels, with particular attention to the lowest renal artery (LoRA). METHODS From 2016 to 2019, all EVAR performed with either CO2 or ICM were analyzed and compared. CO2-EVAR was performed using an automated injector (600 mm Hg pressure; 100 cc volume); a small amount of ICM was injected in case of difficulty in LoRA visualization or doubts at the completion angiogram. Clinical and CT-Scan preoperative characteristics were considered. The study endpoints were technical success, amount of ICM and radiation dose, postoperative renal function and possible CO2-related adverse events. Statistical analysis was by Fisher's exact, t-Student, Mann-Whitney tests and ROC curve. RESULTS In the considered period, 321 EVAR procedures, 72 (22.4%) with CO2 and 249 (77.6%) with ICM, were performed. The 2 groups were similar for clinical characteristics and preoperative renal function. ICM was injected in a significantly lower amount in the CO2-EVAR group (52.8 ± 6.1 vs. 88.1 ±9.2 cc, P < 0.001), which received a significantly higher mean radiation dose (Total DAP: 500,550.8 ± 377,394.6 mGy/cm2 CO2-EVAR vs. 332,301.8 ±230,139.3 mGy/cm2 ICM-EVAR, P = 0.001). Postoperative eGFR decreased significantly less in the CO2-EVAR (2.3 ± 1.1 mL/min) compared with the ICM-EVAR group (10.6 ±5.3 mL/min), P < 0.001. LoRA was correctly visualized in 50/72 (69.4%) cases of CO2-EVAR, which had a significantly longer proximal neck (Median [IQR]: 30 [14] vs. 18 [15] mm, P = 0.001). At ROC curve, a proximal neck length >24.5 mm was predictive of LoRA visualization (72.1% sensitivity, 73.8% specificity). Three CO2-EVAR cases had intraoperative transient hypotension with no consequences. Sixteen/72 (22.2%) CO2-EVAR procedures were performed using 0 cc of ICM. CONCLUSIONS CO2-EVAR by automated injections is safe and requires a lower amount of ICM if compared with ICM-EVAR, with a consequent significant benefit on postoperative renal function. If specific anatomical situations are present, ICM may be completely unnecessary. The radiation dose is however significantly higher, therefore procedural protocols need further refinements.

Abstract
Background: The outcomes of carotid endarterectomy (CEA) are constantly reported in a multitude of studies; however, the specific causes of perioperative stroke have been scarcely investigated. The aim of the present study was to analyze and categorize the causes of perioperative strokes after CEA. Methods: All CEAs performed from 2006 to 2019 in a single center were collected. CEA was routinely performed under general anesthesia, with routine shunting and patching, using cerebral near-infrared spectroscopy monitoring. Carotid exposure technique was classified as either clamped-dissection (CD) or preclamping-dissection (PCD) if the carotid bifurcation was dissected after or prior to carotid clamping. Perioperative and 30-day strokes and their possible mechanisms were evaluated according to preoperative symptoms and surgical technique adopted. Results: Among 1760 CEAs performed, 30 (1.7%) perioperative strokes occurred. 14 (47%) were identified upon emergence from general anesthesia, and 16 (53%) were noted in the first 30 days following intervention. Stroke etiology was categorized as follows: technical (acute thrombosis or intimal flap or due to intraoperative complications), embolic (no recognized technical defect), hemorrhagic, or contralateral. Symptomatic patients had a significantly higher rate of any type of stroke than asymptomatic patients (3.8% vs 0.9%, P = .0001). CD was protective for postoperative stroke (0.9% vs 3.1%, P = .001) in both symptomatic and asymptomatic patients (2.5% vs 5.9%, P = .05; 0.4% vs 1.9%, P = .005), particularly for the cohort in which symptomatic patients (0.7% vs 3.2%, P = .04) suffered postoperative embolic stroke. Conclusion: Perioperative stroke in CEA may be multifactorial in etiology, including a result of technical errors. A CD technique may help reduce the incidence of perioperative stroke.

Abstract
OBJECTIVES The ongoing literature recommends carotid endarterectomy (CEA) primarily for patients with neurological symptoms, however CEA can be precluded by the onset of a severe stroke or a total carotid occlusion. The present study aims to evaluate the effect of unheralded strokes in patients with a previously asymptomatic carotid stenosis (ACS) possibly considered for CEA. MATERIALS AND METHODS From 2009 to 2019, patients with an unheralded stroke from an ACS were considered. By neurological examination, patients were divided in unfit-for-CEA (uCEA) - either for the severity of the stroke (according to modified Rankin-Scale - mRS) or the onset of a total carotid occlusion - and patients submitted to CEA. Predictors for uCEA and stroke severity were evaluated. RESULTS Over a total of 532 patients with symptomatic carotid stenosis, 277 (52%) with unheralded stroke were included in the study. One hundred and one (36%) were considered uCEA: 64(23%) due to their neurological conditions (mRS:5) and 37 (13%) because of the onset of carotid occlusion. One hundred seventy-six (64%) patients underwent CEA. The preoperative medical therapy was similar in uCEA vs CEA patients. Age≥80 years and female sex were independently associated with uCEA (OR:5.9, 95%CI:3.1-11.4, P<.01; OR:3.9, 95%CI:2.0-7.6, P<.01. respectively). Patients submitted to CEA had mRS: 0-2 in 102(37%) cases and mRS:3-4 in 74 (27%). The contralateral carotid occlusion (CCO) was independently associated with mRS:3-4 (OR:8.4, 95%CI 1.8-79, P=.01). Postoperative stroke rate after CEA was 2.9% (4/167); patients with preoperative mRS:3-4 had a higher risk for postoperative stroke compared to those with mRS:0-2 (5.9% vs. 0%. P=.02). CONCLUSIONS An unheralded stroke in patients with ACS leads to a severe neurological damage in more than half of cases, either precluding CEA (36%) or increasing the risk of postoperative complications (27%). Female sex, age≥80 and CCO are independent predictors of these occurrences and should be considered in ACS patients.

Abstract
Patients with carotid artery stenosis (CAS) are commonly defined as asymptomatic or symptomatic according with their neurological conditions, however, emerging evidences suggest stratifying patients according also with the presence of cerebral ischemic lesions (CIL). In asymptomatic patients, the presence of CIL increases the risk of future neurologic event from 1% to 4% per year, leading to a stronger indication to carotid revascularization. In symptomatic patients, the presence of CIL does not seem to influence the outcome of the carotid revascularization if the volume of the lesion is small (<4,000 mm3); the benefit of the revascularization is also more significant if performed within 2 weeks from the index event. However, high volume (>4,000 mm3) CIL are associated in some experiences with a higher risk of carotid revascularization suggesting to delay the carotid revascularization for at least 4 weeks. As a matter of fact, the evaluation of CIL dimensions and characteristics in patients with CAS gives to the physician involved in the treatment a valuable adjunctive tool in the choice of the ideal treatment.

Abstract
OBJECTIVE Iliac limb occlusion (ILO) is a complication of endovascular aortic repair (EVAR) and requires re-intervention in most cases. Attention to any intra-operative defect of iliac limbs and arteries may prevent ILO. The study aimed to analyse the long term effect of an intra-operative protocol of iliac limb treatment during EVAR on ILO. METHODS Patients treated from 2012 to 2017 for abdominal aortic aneurysm (AAA) with standard EVAR were collected prospectively. Pre-operative computed tomography angiography anatomical characteristics were evaluated. The protocol for intra-operative iliac limb management was: a. pre-EVAR angioplasty of common/external iliac artery stenosis; b. precise contralateral iliac limb deployment at the same level of the flow divider; c. iliac limb kissing ballooning with high pressure non-compliant balloons; d. iliac limb stenting for residual tortuosity/kink and adjunctive external iliac stenting for residual stenosis/dissection after EVAR. ILO was evaluated at 30 days and at follow up, which was performed by duplex ultrasonography before discharge, at three, six, and 12 months and yearly thereafter. Kaplan-Meier and Cox linear regression were used. RESULTS Four hundred and forty-two patients and 884 iliac limbs were included in the study. Severe iliac tortuosity and calcification were present in 15% (132/884) and 8% (70/884), respectively. External iliac angioplasty and stenting of iliac limb were performed in 2% (18/884) and 9.5% (84/884) of limbs. The thirty day mortality was 1.6%, with no ILO. At a mean follow up of 33 ± 12 months, ILO occurred in 7/884 (0.8%) limbs of six patients. Five ILO were treated by endovascular relining, two surgically: one by femorofemoral bypass and one by surgical explant. On univariable analysis, sac shrinkage was significantly associated with ILO (HR 1, 95% CI 0.8-2.5, p = .043). CONCLUSION A protocol of aggressive iliac limb treatment in EVAR leads to a very low rate of late ILO. The role of sac shrinkage in ILO should be investigated further.

J Stroke Cerebrovasc Dis 2020; 29:105108.

Abstract
AIM Silent brain infarction (SBI) is associated with an increased risk of stroke in patients with asymptomatic carotid stenosis (ACS), and is therefore one of the criteria for performing carotid endarterectomy (CEA). Despite an extensive literature, this issue is still a matter of debate. Aim of the present work was to evaluate incidence and predictors of SBI in patients undergoing CEA for ACS, and to investigate its possible impact on CEA outcome. METHODS All patients submitted to CEA in a single academic center from 2005 to 2019 were prospectively inserted into a specific database. The presence of SBI was evaluated by preoperative computed tomography (CT), considering exclusively infarctions in the carotid territories from an athero-embolic source. Preoperative characteristics were investigated as possible risk factor for SBI at the uni- and multivariate analysis. The impact of SBI on stroke occurrence after CEA was also evaluated. RESULTS In the designated period, over a total of 1288 ACS considered and submitted to CEA, 105 (8.2%) were associated with SBI. Male sex, hypertension, dyslipidaemia, smoking, contralateral carotid occlusion and severity of carotid stenosis were associated with SBI at the univariate analysis; preoperative statin therapy showed to be a protective factor. At the multivariate analysis, contralateral carotid occlusion and severity of stenosis were independently associated with SBI (OR: 3.16, 95%CI 1.62-6.18, P=.001; OR: 1.04, 95%CI 1.01-1.07, P=.004, respectively), with statin therapy confirmed as a protective factor (OR: 0.60, 95%CI: 0.40-0.92, P=.002). Overall post-CEA stroke rate was 0.9%, with a higher post-operative risk independently predicted by the presence of SBI (OR:4.23, 95%CI: 1.40-12.73, P=.01). CONCLUSION SBI is present in 8% of patients with ACS, and is significantly associated with contralateral carotid occlusion and severity of the carotid stenosis. Statin therapy reduces the occurrence of this phenomenon. The presence of SBI should be carefully considered in indication to CEA since it significantly increases the surgical risk.
