Abstract
INTRODUCTION Meta-analyses and emerging randomized data indicate that second-generation ('mesh') carotid stents (SGS) may improve outcomes versus conventional (single-layer) stents but clinically-relevant differences in individual SGS-type performance have been identified. No comparisons exist for SGS versus carotid endarterectomy (CEA). EVIDENCE ACQUISITION Thirty-day death (D), stroke (S), myocardial infarction (M), and 12-month ipsilateral stroke and restenosis in SGS studies were meta-analyzed (random effect model) against CEA outcomes. Eligible studies were identified through PubMed/EMBASE/COCHRANE. Forest plots were formed for absolute adverse evet risk in individual studies and for relative outcomes with each SGS deign versus contemporary CEA outcomes as reference. Meta-regression was performed to identify potential modifiers of treatment modality effect. EVIDENCE SYNTHESIS Data were extracted from 103,642 patients in 25 studies (14 SGS-treated, 41% symptomatic; nine randomized controlled trial (RCT)-CEA-treated, 37% symptomatic; and two Vascular Quality Initiative (VQI)-CEA-treated, 23% symptomatic). Casper/Roadsaver and CGuard significantly reduced DSM versus RCT-CEA (-2.70% and -2.95%, P<0.001 for both) and versus VQI-CEA (-1.11% and -1.36%, P<0.001 for both). Gore stent 30-day DSM was similar to RCT-CEA (P=0.581) but increased against VQI-CEA (+2.38%, P=0.033). At 12 months, Casper/Roadsaver ipsilateral stroke rate was lower than RCT-CEA (-0.75%, P=0.026) and similar to VQI-CEA (P=0.584). Restenosis with Casper/Roadsaver was +4.18% vs. RCT-CEA and +4.83% vs. VQI-CEA (P=0.005, P<0.001). CGuard 12-month ipsilateral stroke rate was similar to VQI-CEA (P=0.850) and reduced versus RCT-CEA (-0.63%, P=0.030); restenosis was reduced respectively by -0.26% and -0.63% (P=0.033, P<0.001). Twelve-month Gore stent outcomes were overall inferior to surgery. CONCLUSIONS Meta-analytic integration of available clinical data indicates: 1) reduction in stroke but increased restenosis rate with Casper/Roadsaver, and 2) reduction in both stroke and restenosis with CGuard MicroNET-covered stent against contemporary CEA outcomes at 30 days and 12 months used as a reference. This may inform clinical practice in anticipation of large-scale randomized trials powered for low clinical event rates (PROSPERO-CRD42022339789).

Abstract
Chronic venous disorders (CVD) of the lower limbs can be treated with different strategies. Typically, conservative management is based on compression therapy, anticoagulants and venoactive drugs. Endovenous treatments remain the gold standard to treat saphenous insufficiency, with sclerotherapy and surgery maintaining a role in selected cases. In addition, several 'unconventional' approaches have been proposed to prevent CVD progression and complications, minimize symptoms and improve the quality of life and postoperative outcomes. Among these, balneotherapy and aquatic exercises are proving as valid and effective supporting treatments, as mentioned in a growing number of scientific publications. Moreover, aquatic protocols have been studied for both venous and lymphatic insufficiency. For these reasons, they were mentioned in the last CVD guidelines provided by the European Society for Vascular Surgery. The aim of this narrative review is to overview and summarize current literature evidences on the role and effectiveness of aquatic rehabilitative protocols in CVD, reviewing old and current literature. Furthermore, the physical basis of the effects of water immersion on lower limb venous and tissues modifications are also described.

Abstract
The sapheno-femoral junction (SFJ) and the great saphenous vein (GSV) are recognized as one of the main sources of reflux in chronic venous disease. Moreover, reflux time is considered as the main parameter to characterize GSV disease. Despite this, it is well-known in the clinical practice that not all patients with SFJ/GSV reflux are similar, in terms of disease severity and degree. Some other anatomical findings, such as SFJ and GSV diameters, as well as the absence/incompetence of suprasaphenic femoral valve (SFV) might be of interest to better "quantify" the disease severity. The aim of this paper is to describe, through a duplex scan analysis, the relationship between SFJ incompetence, GSV/SFJ diameter and SFV absence/incompetence, to identify if there are patients with "severe" GSV disease and a potential higher recurrence rate after invasive treatments.

Abstract
PURPOSE The aim of this retrospective single-center study is to describe and analyze short-, mid-, and long-term risk factors for great saphenous vein (GSV) recanalization after endovenous radiofrequency ablation (RFA). MATERIALS AND METHODS All consecutive patients with GSV incompetence and varicose veins underwent RFA were enrolled between 2009 and 2018. Data on demographic, pre- and postoperative color Doppler scan (CDUS) findings, perioperative complications, and follow-up were prospectively collected. Primary outcome was GSV recanalization rate at 1 week after RFA. Secondary outcomes were postoperative complication rate, as well as GSV recanalization rate at 1, 3, and 5 years after RFA. Risk factors for recanalization were also analyzed, for each follow-up assessment, identifying differences in recanalized (Rec) and non-recanalized (nRec) groups. RESULTS During the study period, 1297 patients were treated. Among these, 1265 had at least 1 week of follow-up. Mean follow-up time was 3.0 ± 1.9 years. Recanalization rate at 1 week, 1, 3, and 5 years was 2.4%, 4.3%, 9.3%, and 17.5%, respectively. After multivariate analysis for each follow-up evaluation, CEAP classes C4 and 5, as well as preoperative GSV diameter >6 mm and history of smoking were found to be independent predictors of recanalization. Furthermore, age >61 years and postoperative complications such as pigmentation, edema, and paresthesia were found to be dependent risk factors. CONCLUSION RFA remains a safe and durable technique to ablate incompetent GSV. Despite this, particular attention should be paid to patients with high CEAP classes to avoid short and long-term recanalization.

Abstract
BACKGROUND In asymptomatic carotid stenosis (ACS), different plaque types, i.e. lipidic (LP), fibrous (FP), and calcific (CP), could have different hemodynamic and structural behaviors. METHODS Different carotid plaques, reconstructed from medical imaging of ACS >70%, were analyzed by computing fluid structure interaction (FSI), modeling the spatial distribution of wall shear stresses (WSS), plaque displacements (D), von Mises stresses (VMS), and absorbed elastic energy (AEE) together with their maximum-in-space values at the systole (WSS<inf>syst</inf>, D<inf>syst</inf>, VMS<inf>syst</inf> and AEE<inf>syst</inf>). RESULTS WSS resulted significantly higher in CP, whereas D and VMS showed the highest values for LP. Regarding AEE<inf>syst</inf> stored by the plaques, LP absorbed in average 2320 J/m3, FP 408 J/m3 (470%) and CP 99 J/m3 (2240%), (P<0.01, P<0.01, and P<0.01, respectively). CONCLUSIONS Depending upon their nature, plaques store different deformations and inner distributions of forces, thus potentially influencing their vulnerability.

Abstract
The term “recurrence” in chronic venous disease remains not yet well defined, despite numerous reports describing patterns and causes of the presence of recurrent varicose veins (RVVs). Moreover, saphenous trunk recanalization (STR) has also been documented as one of the major source of RVVs and it is widely used to indicate the “failure” of endovenous ablation. Finally, reappearance of venous symptoms (VSym) should be considered to reach a complete “recurrence” evaluation. RVVs, STR, and VSym rates and mutual co-presence after endovenous treatments are still unclear. The aim of this report is to describe and analyze these three recurrence components after 6 years in patients underwent radiofrequency ablation of the great saphenous vein.

Abstract
Quality of life (QoL) in patients with chronic venous disorders has a central role to decide the correct treatment approach. In particular, in case of mini-invasive therapy, such as endovenous radiofrequency ablation (RFA), the postoperative QoL improvement remains one of the most important outcome to be reached. Despite this, very few data are published on the long-term QoL modifications after RFA. The aim of this brief report is to describe and analyze the role of QoL scales in a population of patients treated with RFA of the great saphenous vein and phlebectomies, highlighting results in short- and long-term follow-up period, and differences between recanalized and non-recanalized patients.

Abstract
OBJECTIVE The aim of this study is to compare and to test the performance of all available risk scoring systems (RSSs) designed to predict long-term survival rate in asymptomatic candidate patients for carotid endarterectomy (CEA) for significant carotid artery stenosis. METHODS Data on asymptomatic patients who underwent CEA in three high-volume centers were prospectively recorded. Through literature research using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, six RSSs were identified for the intent of the study. Primary endpoints were 3- and 5-year survival rates after CEA. All items used as variables to compose multiple RSSs were applied to every patient in the study population. The 3- and 5-year mortality prediction rates for each score were assessed by sensitivity, specificity, and predictive negative and positive value calculation, as well as univariable Cox proportional hazard models with the Harrell C index. RESULTS During the study period, 825 CEAs in 825 asymptomatic patients were analyzed. All items used in RSSs were available in the dataset, with some concerns regarding their definition and application among RSSs. The 3- and 5-year survival rates of the study cohort were 94.5% and 90.3%, respectively. Among the six RSSs analyzed, no RSS demonstrated optimal results in terms of mortality rate prediction accuracy, although some scores had good diagnostic and risk of death precision. CONCLUSIONS RSSs, when used alone, fail to optimally detect postoperative life expectancy in asymptomatic CEA patient candidates. Further prospective controlled studies are needed to compose and validate RSSs with better calibration to predict outcomes.

Abstract
A 41-year-old male presented for pain treated with oxycodone. A zone-2 thoracic endovascular aortic repair with distal PETTICOAT (provisional extension to induce complete attachment) for complicated Type-IIIB aortic dissection was performed 18 months before. Repeated hospitalizations did not show any issues to justify the recurrent pain. The aortic nature of the pain was suspected considering the plug as a pain trigger. Through a left thoracoabdominal incision in the eighth intercostal space, the candy plug was removed. Pain diminished after thoracoabdominal surgery steadily.

Abstract
The acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the COVID-19 disease, a global pandemic. A strong association has been documented between COVID-19 and cardiovascular events, although the exact pathophysiological mechanism is still unclear. Carotid atherothrombosis and ischemic stroke represents one of the possible severe manifestations of COVID-19, as a leading cause of long-term disability and death. Different complex intertwined mechanisms seem to underlie the endothelitis which is the cause of multiple cardiovascular manifestations. To date, few case series describing COVID-19 and acute ischemic stroke caused by cervical carotid thrombosis have been published. All the patients shared common similar radiographic features, comorbidities, and biomarker profiles. The aim of this brief review is to analyze the impact of COVID-19 pandemic in the management of a Vascular Surgery Department, changing the daily vascular practice, as well as to provide practical suggestions for symptomatic carotid stenosis, while reviewing published literature.

Abstract
Since the advent of the 2019 coronavirus (COVID-19) outbreak, vascular specialists have faced dramatic changes in clinical and surgical practice. Although COVID-19 pulmonary signs and symptoms were the most pertinent problems initially, in the long term cardiovascular complications became the most fearsome, with poor outcomes in terms of morbidity and mortality. Algorithms and decision-making procedures have been modified, not only to treat new clinical findings in COVID-19 positive patients, but also to avoid complications related to pulmonary and systemic infections. Additionally, COVID-19 negative patients experienced challenging management, due to hospital crowding, the risk of nosocomial COVID-19 transmission, and pandemic emergencies. In this context, aortic interventions were subject to several difficulties. First, in COVID-19 positive patients, there was the onset of new pathological scenarios including thrombotic manifestations and the subsequent complications. Second, in both COVID-19 negative and positive patients, there was a need to deliver optimal treatment with acceptable perioperative risks, forcing a rethinking of decisionmaking especially in terms of indications for treatments. The aim of this systematic review is to present evidence published on COVID-19 and aortic-related issues, highlighting some challenging aspects regarding management, treatment and outcomes.

Abstract
BACKGROUND A total percutaneous approach for management of aortic pathologies with endovascular grafts requires the use of large size delivery-systems. The diameter of these delivery systems usually exceeds the recommended sizes for most of the currently available percutaneous closure devices. A safe, effective and simple vascular access site closure device is desirable for success for percutaneous procedures for aortic pathologies. Hence, we aim to study safety and effectiveness of the use of a single suture based vascular access closure device (ProGlide) using a technique involving serial up and downsizing of the sheath size to achieve access site hemostasis in patients undergoing endovascular graft placement using femoral artery approach. MATERIALS AND METHODS We studied all consecutive patients who underwent endovascular grafting from January 2018 to December 2019. It is a retrospective observational study comparing procedural and short-term outcomes between single ProGlide use and surgical cut-down for femoral access site closure. We excluded patients with femoral artery minimal luminal diameter less than 5 mm, the presence of an aneurysm of the femoral artery, ≥180 degrees of calcium present at femoral/ external iliac artery and history of any vascular closure device use in the last six months. RESULTS We included 30 patients in single ProGlide group and 30 patients in the surgical cut-down group. One-third of the procedures were urgent procedures in the single Proglide group. Single ProGlide was successful in 93.34% patients and failure (6.66%) was seen due to hematoma and pseudoaneurysm in one patient each detected before discharge. The primary end-point defined by the success of procedure did not differ between the two groups. There were higher complications in the surgical group till 30 days as evidenced by infection, hematoma and neuronal injury. The secondary end-point, defined by the composite of complication events after discharge till 30 days was significantly higher in the surgical group (P-0.005) CONCLUSION: In patients with suitable femoral artery anatomy who undergo endovascular graft placement, effective hemostasis can be achieved safely using up and downsizing of the sheath with a single suture-based technique (Proglide). The results of the study could be considered hypothesis generating and needs to be confirmed in a randomized controlled trial before being adopted in clinical practice.

Abstract
The coronavirus disease 2019 (COVID-19) outbreak has profoundly affected all aspects of medicine and surgery. Vascular surgery practice and interventions were also forced to change in order to deal with new COVID-19–related priorities and emergencies. In this setting, difficulties in aortic disease management were two-fold: new vascular complications related to COVID-19 infection and the need to guarantee prompt and correct treatment for the general “non-COVID-19” population. Furthermore, discomfort deriving from precautions to minimize the risk of virus transmission among patients and among health care professionals, the need to separate COVID-19–positive from COVID-19–negative patients, and the high incidence of postoperative complications in COVID-19 cases created a challenging scenario for cardiac operations. The aim of this review was to provide evidence derived from the published literature (case reports, case series, multicenter experience, and expert opinion) on the impact of the COVID-19 outbreak on aortic vascular surgery services and interventions, describing COVID-19–related findings, intraoperative and postoperative outcomes, as well as the impact of the COVID-19 outbreak on noninfectious aortic patients.

Abstract
Atherosclerosis is a systemic disease that leads to accumulation of deposits, known as atherosclerotic plaques, within the walls of the carotids. In particular, three types of plaque can be distinguished: soft, fibrous, and calcific. Most of the computational studies who investigated the interplay between the plaque and the blood flow on patient-specific geometries used nonstandard medical images to directly delineate and segment the plaque and its components. However, these techniques are not so widely available in the clinical practice. In this context, the aim of our work was twofold: (i) to propose a new geometric tool that allowed to reconstruct a plausible plaque in the carotids from standard images and (ii) to perform three-dimensional (3D) fluid-structure interaction (FSI) simulations where we compared some fluid-dynamic and structural quantities among 15 patients characterized by different typologies of plaque. Our results highlighted that both the morphology and the mechanical properties of different plaque components play a crucial role in determining the vulnerability of the plaque.

Abstract
BACKGROUND In the current literature, correlations between a contralateral carotid artery occlusion (CCO) with mortality and major adverse cardiac or cerebrovascular events (MACCE) rates after carotid artery stenting (CAS) are often described with controversial conclusions. Moreover, long-term results of mortality, MACCE and restenosis rate are scarcely reported. This study examined the association between a CCO and the short- and long-term outcomes after CAS. METHODS One hundred and forty-six patients with CCO and without (No-CCO) who underwent between 2010 and 2017 to a CAS procedure in a single institution were retrospectively evaluated. The primary aim of the study was to evaluate mortality and MACCE rates in the short-term (defined as the occurrence during hospitalization and within 30-day) and after 3-year follow-up. The secondary aim of the study was to examine the restenosis rates in the short- and long-term period. RESULTS The overall success of CAS was 99.3% and the 30-day all-cause mortality rate was 0.7% (one death). About MACCE, there were no major strokes in the CCO groups and 1 (1.4%) in the No-CCO group (P=1.00). The rate of 30-day minor strokes was 1.4% (1 patient) in the CCO group and 2.7% (2 patients) in the No-CCO group (P=1.00). In the 3-year follow-up, death occurred in 11 CCO vs. 6 No-CCO patients, respectively (15.1% vs. 8.2%, P=0.30). Regarding MACCE, major stroke occurred in 6 CCO vs. 2 No-CCO patients (8.2% vs. 2.7%, P=0.27), minor stroke in 6 CCO vs. 6 No-CCO (8.2% vs. 8.2%, P=1.0) and myocardial infarction in 6 CCO (8.2%) vs. 3 No-CCO patients (8.2 vs. 4.1%, P=0.49), respectively. Regarding the 30-day restenosis rate, it was observed in one patient (1.4%) in the CCO group while no cases were recorded in the No-CCO group, respectively (P=1.00). In the 3-year follow-up, greater than >50% restenosis was observed in 7 patients (9.6%) in the CCO group and in one patient (1.4%) in the No-CCO group (P=0.06), respectively. Kaplan-Meier survival analysis revealed that CCO patients had a lower 3-year freedom from restenosis rate with respect to the No-CCO group (87.6% vs. 98.6%, P=0.024). A Cox regression model on 3-year restenosis highlighted female gender and hypertension to be statistically significant predictors of restenosis. CONCLUSIONS Patients with a preexisting CCO did not show a significative increased risk of procedural adverse events after CAS both in the immediate and long-term follow-up, but on the long term they are more likely to experience restenosis. CCO condition should be considered always as a clinical manifestation of a more aggressive carotid atherosclerosis.

Abstract
BACKGROUND The aim of this study was to investigate the influence of the aortic arch type on technical and clinical success of carotid artery stenting (CAS) procedure. METHODS Clinical and anatomical data of consecutive patients who underwent CAS from 2010 to 2018 were prospectively collected and retrospectively analyzed. Primary outcome was technical success, define as successful stent delivery and deployment and <30% residual carotid stenosis. Secondary outcomes were death, stroke, myocardial infarction (MI) and transient ischemic attack (TIA) rates at 30 days after CAS. Subgroups analysis with asymptomatic and symptomatic patients were also performed. RESULTS During the study period, 523 patients were enrolled and analyzed. Among these, 176 (33.6%) had Type I, 227 (43.4%) had Type II and 120 (23.0%) had Type III or bovine aortic arch (BAA) type. Technical success rate was achieved in 96.0% of cases. At 30 days, if compared with Type I or II, patient with Type III or BAA experienced a higher death rate (0 vs. 0 vs. 1.8%, respectively; P=0.056) and combined postoperative stroke/TIA rate (3% vs. 2.8% vs. 9.9%, respectively; P=0.012). No differences for same outcomes between asymptomatic and symptomatic patients were described, although the latter group experienced more postoperative MI. A multivariate analysis revealed Type III or BAA as an independent risk factor for postoperative stroke/TIA (HR 3.23, IC95% 1.40-7.45; P=0.006). CONCLUSIONS In this cohort of patients, death and postoperative neurological complications rates were associated with Type III or BAA, irrespective of symptomatic patients' status. Extremely attention is required during perioperative period in patients who were candidate to CAS and with challenging aortic arch anatomy.

Abstract
AIMS The aim of the present study was to evaluate periprocedural and 30-day outcomes in a prospective series of patients treated with the CGuard Embolic Prevention System (EPS). METHODS AND RESULTS From April 2015 to June 2016, a physician-initiated prospective multicentre study was performed in 200 consecutive patients admitted for protected carotid artery stenting (CAS) and treated using the CGuard EPS in twelve vascular centres. Outcome measures were: technical success, periprocedural (0-24 hours) and post-procedural (24 hours-30 days) major and minor strokes, death, acute myocardial infarction (AMI), transient ischaemic attack (TIA), and external carotid occlusion. In three centres, consecutive diffusion-weighted magnetic resonance cerebral imaging (DW-MRI) was performed ≤72 hours prior to and within 72 hours after the intervention. A distal embolic protection device was employed in 182 patients (91%). Technical success was 100%. No death, AMI or major stroke occurred periprocedurally. There were two TIAs and five periprocedural minor strokes (2.5%), including one thrombosis solved by surgery. In the remaining patients (199/200; 99.5%) one-month follow-up duplex ultrasound revealed optimal technical results. Post-procedural clinical follow-up was uneventful. No external carotid artery occlusion occurred. New post-procedural DW-MRI lesions were detected in 12 patients out of 61 (19.6%), including bilateral in five (8.2%) and isolated ipsilateral in six (9.8%), whereas one patient (1.6%) had contralateral only lesions. CONCLUSIONS Multicentre multi-specialty use of the CGuard EPS in routine clinical practice was associated with no major periprocedural neurologic complications and a total elimination of post-procedural neurologic complications by 30 days.

Abstract
Objectives Carotid artery stenosis is thought to cause up to 10% of ischemic strokes. Historically, carotid artery endarterectomy has shown a higher risk of perioperative adverse events for women. More recent trials reported conflicting results regarding the benefit of carotid artery endarterectomy and carotid artery stenting for men and women. The aim of the present retrospective study was to investigate the influence of gender on the short- (30 days) and long-term (3 years) outcomes of carotid artery endarterectomy and carotid artery stenting in a single centre. Methods From 2010 to 2017, 912 consecutive symptomatic and asymptomatic patients who underwent carotid artery endarterectomy (389, 42.7%) or carotid artery stenting (523, 57.3%) in a single institution had been evaluated to determine the influence of sex (540 men, 59.2%, vs. 372 women, 40.8%) on the outcomes after both revascularization procedures during three years of follow-up. The primary endpoint was the incidence of death, stroke, myocardial infarction, and restenosis in the short-term follow-up. The secondary endpoint was the incidence of death, stroke, myocardial infarction, and restenosis in the long-term follow-up. Results Mean clinical follow-up was 21.1 (16.1) months. Women had internal and common carotid artery diameters significantly smaller with respect to men. For peri-procedural outcomes, women undergoing carotid artery stenting had a higher risk of moderate (50–70%) restenosis (6 women, 2.9%, vs. 3 men, 1.0%). For long-term outcomes, women undergoing carotid artery endarterectomy had a higher rate of moderate restenosis (16 women, 16.3%, vs. 11 men, 7.6%). No significant differences in long-term outcomes were observed between men and women undergoing carotid artery stenting, even after stratification for baseline risk factors. Conclusions Contrary to previous reports, from this single-centre study, long-term risk of events seems to be higher in women who underwent carotid artery endarterectomy than in those who underwent carotid artery stenting, while fewer differences were observed in men.

Abstract
AIMS The metabolic syndrome (MetS) is composed of a cluster of related cardiovascular risk factors. The aim of the present study was to determine how MetS contributes to short- (30-day) and long-term complications and restenosis after carotid endarterectomy (CEA) or stenting (CAS). METHODS A consecutive cohort of 752 patients undergoing CEA (n = 314) and CAS (n = 438) in a single institution was examined, of which 296 (39.4%) were identified as having MetS. All patients were followed-up with carotid duplex ultrasound scan of the supraaortic vessels and a neurological assessment of symptoms status at 30-day postprocedure and at 3, 6, and 12 months, with annual follow-up thereafter for 3 years. RESULTS Patients with MetS had a significant increased risk in their 30-day death, major adverse events (MAE), and restenosis rates, both after CEA and after CAS (death: 0.7% vs 0.0%; MAE: 5.3% vs 2.7%; and restenosis: 1.7% vs 0.2%; p < 0.05). The MAE and restenosis rates remained statistically different at 36 months, with both procedures (29.2% vs 24.2% and 9.5% vs 3.3%, p < 0.05, for patients with and without MetS, respectively). Among the components of MetS, high fasting serum glucose, low high-density lipoprotein cholesterol, and elevated body mass index were associated with increased risk of complications at 30 days and within 36 months. CONCLUSIONS The current study suggested that the presence of MetS is an important risk factor for morbidity and restenosis after CEA and CAS.

Abstract
PURPOSE This single centre study investigates the influence of diabetes mellitus on outcomes following carotid artery endarterectomy or stenting. METHODS In total, 752 carotid revascularizations (58.2% carotid artery stenting and 41.8% carotid endarterectomy) were performed in 221 (29.4%) patients with diabetes and 532 (70.6%) patients without diabetes. The study outcomes were death, disabling and non-disabling stroke, transient ischaemic attack and restenosis within 36 months after the procedure. RESULTS Patients with diabetes had higher periprocedural risk of any stroke or death (3.6% diabetes vs 0.6% no diabetes; p < 0.05), transient ischaemic attack (1.8% diabetes vs 0.2% no diabetes; p > 0.05) and restenosis (2.7% diabetes vs 0.6% no diabetes; p < 0.05). During long-term follow-up, there were no significant differences in Kaplan-Meier estimates of freedom from death, any stroke and transient ischaemic attack, between people with and without diabetes for each carotid artery stenting and carotid endarterectomy subgroup. Patients with diabetes showed higher rates of restenosis during follow-up than patients without diabetes (36-months estimate risk of restenosis: 21.2% diabetes vs 12.5% no diabetes; p < 0.05). CONCLUSION The presence of diabetes was associated with increased periprocedural risk, but no further additional risk emerged during longer term follow-up. Restenosis rates were higher among patients with diabetes.

Abstract
Purpose Endovascular ablation of the great saphenous vein has been proposed as a less invasive alternative to conventional ligation and stripping of varicose veins. Outcomes of patients treated with the radiofrequency ablation ClosureFast™ system over an eight-year period from a single-center were evaluated. Methods Three-year follow-up data included duplex ultrasound scan, complication rate, and questionnaires to assess patients' QOL, level of pain, and days off work. Results A total of 1080 consecutive patients (49.5 ± 18.6 years, 72% female, mean body mass index: 25.44 ± 4.1 kg m-2) underwent radiofrequency ablation for incompetent saphenous veins in a single institution. Occlusion of the great saphenous vein was obtained in 98.6% and 93.8% cases at the end of the procedures and within 36 months, respectively. Only three deep venous thromboses and minor complications occurred in this series throughout the first week from the procedure. A decrease of the external vein diameter, equal to 72.7% and 31.1% of the pretreatment diameter, was observed at 1 week and 36 months, respectively. The average Aberdeen Varicose Vein Questionnaire score improved from 18.06 ± 9.47 before treatment to 11.56 ± 10.23 at 12 months, with no significant differences in the subsequent follow-up. SF-36 QOL scores significantly improved after the procedure in all domains, while there were no changes over time. Patients reported a prompt return to normal daily activities (1.5 ± 0.7 days) and work (3.1 ± 1.9 days). Body mass index influenced QOL scores, while it did not affect great saphenous vein diameter reduction during the follow-up. On the contrary, Clinical Etiologic Anatomic Pathophysiologic class significantly influenced both great saphenous vein diameter reduction after the treatment and QOL scores within 36 months. Conclusion Results of this retrospective monocentric, large patients study suggest that radiofrequency ablation of the great saphenous vein may be a safe and efficient alternative to conventional surgery.

Abstract
RATIONALE Restenosis due to intimal hyperplasia (IH) is a major clinical issue that affects the success of lower limb endovascular surgery. After 1 year, restenosis occurs in 40% to 60% of the treated vessels. The possibility to reduce IH using local antiproliferative drugs, such as taxols, has been the rationale for the clinical applications of drug-eluting stents and drug-eluting balloons (DEBs). The purpose of this study was to evaluate the clinical and instrumental efficacy of DEBs versus simple percutaneous transluminal angioplasty (PTA) in patients affected by chronic limb ischemia (CLI) with tibial artery "de novo" lesions. METHODS A retrospective analysis was performed and included all consecutive patients who underwent endovascular treatment for CLI in our centers between January 2011 and March 2013. Inclusion criteria were (1) "de novo" tibial artery stenosis and (2) Rutherford class >4. Lesions were further divided by TransAtlantic Inter-Societal Consensus (TASC) classification into groups A, B, C, and D. RESULTS Between January 2010 and March 2013, a total of 138 patients underwent simple PTA or DEB for CLI, and the groups were clinically and demographically homogenous. We decided to use DEBs in 70 cases. An improvement in the Rutherford Scale in cumulative and single TASC lesions classification was better in the DEB group (74% vs 51%; P = .024) at 24 months than in the PTA group. In the DEB group, the increase in ankle-brachial index was significantly higher than in the PTA group (P = .039). CONCLUSIONS Our experience in addition to the existing literature supports the use of DEB in patients with CLI Rutherford class >3.

A successful experimental model for intimal hyperplasia prevention using a resveratrol-delivering balloon. J Vasc Surg 2014; 63:788-94.

Abstract
OBJECTIVE Restenosis due to intimal hyperplasia is a major clinical problem that compromises the success of angioplasty and endovascular surgery. Resveratrol (RSV) has demonstrated a beneficial effect on restenosis from angioplasty. Unfortunately, the physicochemical characteristics of RSV reduce the practicality of its immediate clinical application. This work proposes an experimental model aiming to setup an intravessel, elutable, RSV-containing compound. METHODS A 140 μg/mL RSV sterile injectable solution with a suitable viscosity for intravascular administration by drug-delivery catheter (RSV-c) was prepared. This solution was locally administered in the common iliac artery of adult male New Zealand White rabbits using a dedicated device (Genie; Acrostak, Geneva, Switzerland) after the induction of intimal hyperplasia by traumatic angioplasty. The RSV concentrations in the wall artery were determined, and the thickness of the harvested iliac arteries was measured over a 1-month period. RESULTS The Genie catheter was applied in rabbit vessels, and the local delivery resulted in an effective reduction in restenosis after plain angioplasty. Notably, RSV-c forced into the artery wall by balloon expansion might accumulate in the interstitial areas or within cells, avoiding the washout of solutions. Magnification micrographs showed intimal proliferation was significantly inhibited when RSV-c was applied. Moreover, no adverse events were documented in in vitro or in vivo studies. CONCLUSIONS RSV can be advantageously administered in the arterial walls by a drug-delivery catheter to reduce the risk of restenosis.

Abstract
RATIONALE During the past 30 years, myocardial ischemia/reperfusion injury in rodents became one of the most commonly used model in cardiovascular research. Appropriate pain-prevention appears critical since it may influence the outcome and the results obtained with this model. However, there are no proper guidelines for pain management in rats undergoing thoracic surgery. Accordingly, we evaluated three analgesic regimens in cardiac ischemia/reperfusion injury. This study was strongly focused on 3R's ethic principles, in particular the principle of Reduction. METHODS Rats undergoing surgery were treated with pre-surgical tramadol (45 mg/kg intra-peritoneal), or carprofen (5 mg/kg sub-cutaneous), or with pre-surgical administration of carprofen followed by 2 post-surgery tramadol injections (multi-modal group). We assessed behavioral signs of pain and made a subjective evaluation of stress and suffering one and two hours after surgery. RESULTS Multi-modal treatment significantly reduced the number of signs of pain compared to carprofen alone at both the first hour (61±42 vs 123±47; p<0.05) and the second hour (43±21 vs 74±24; p<0.05) post-surgery. Tramadol alone appeared as effective as multi-modal treatment during the first hour, but signs of pain significantly increased one hour later (from 66±72 to 151±86, p<0.05). Carprofen alone was more effective at the second hour post-surgery when signs of pain reduced to 74±24 from 113±40 in the first hour (p<0.05). Stress behaviors during the second hour were observed in only 20% of rats in the multimodal group compared to 75% and 86% in the carprofen and tramadol groups, respectively (p<0.05). CONCLUSIONS Multi-modal treatment with carprofen and tramadol was more effective in preventing pain during the second hour after surgery compared with both tramadol or carprofen. Our results suggest that the combination of carprofen and tramadol represent the best therapy to prevent animal pain after myocardial ischemia/reperfusion. We obtained our results accordingly with the ethical principle of Reduction.

Abstract
Carotid artery stenting (CAS) is a validated option in the treatment of selected extracranial carotid artery stenosis. Carotid artery dissection during CAS is a rare but potentially devastating complication. We report a case of acute dissection and thrombosis of the left internal carotid artery during filter tip wire engaging maneuvers, complicated by intraoperative complete blindness of the left eye. Immediate conversion to carotid endarterectomy was performed under general anesthesia with electroencephalographic monitoring. The patient was discharged home symptomless and remains asymptomatic eight months after the operation, with normal left internal carotid patency and fully recovered eyesight. In conclusion, the management of acute carotid occlusion during CAS requires emergent evaluation and definitive endovascular or open surgical repair to minimize neurologic morbidity. We advocate that all endovascular procedures are carried out in a well-established surgical environment.

Abstract
A 58-year-old Caucasian lady presented for severe left internal carotid artery (ICA) stenosis. Two months before she was operated for right carotid endarterectomy (CEA) in another Institution, complicated with internal carotid artery thrombosis and development of transient hemiplegia and aphasia. Postoperative selective DSA showed the development of an abnormal basal meshwork of collateral vessels with typical evidence for moyamoya disease. Preoperative workup in our Institution included cerebral MRI witch showed two ischemic right frontal and parietal lesions. The patient underwent successful stenting of the left ICA. This is the first report of extracranial ICA stenting in a patient with moyamoya syndrome.

Abstract
AIM To evaluate the benefit of endovascular peripheral revascularization on glucose control in patients with chronic limb ischemia. METHODS AND RESULTS Over a 12 month period, 61 patients (41 male, range 49-88 years of age) presenting with critical limb ischemia (CLI) were treated according to the Trans Atlantic Inter Society Consensus (TASC II) guidelines. After discharge, all patients were asked to measure their glucose level three times daily, and glycated hemoglobin was checked monthly up to 12 months, as well as to fill a questionnaire to assess their Quality of Life (QoL). The revascularization procedure was successful in 90% of cases. Glycemic control and glycated hemoglobin in 22 diabetic patients subgroup were significantly improved after the treatment and remained stable over the follow-up period. There was a significant improvement in QoL that increased steadily from the operation and to reach a plateau after six months. CONCLUSIONS Peripheral percutaneous angioplasty in subjects with CLI significantly improves glycemic control and ameliorates QoL. Revascularization positively effects also long-term diabetes control as well as QoL.

Abstract
AIM The aim of this preliminary study is to evaluate the feasibility and efficacy of CAS as treatment option to endarterectomy when carotid shunt cannot be used safely. METHODS The medical records concerning 469 carotid stenosis treated between January 2006 and December 2009 were retrospectively reviewed, focusing on cross-clamp intolerance during CEA. Patients with cross-clamping intolerance were divided in two groups. Group 1: those that concluded the open procedure with the use of a shunt, and Group 2: those who experience immediate brain intolerance and coma and were immediately converted to an endovascular procedure. Mortality and neurological adverse event rate were compared between shunted CEA and cross-clamping intolerant cases converted into CAS. The secondary end-point was long-term survival. RESULTS Carotid cross-clamp intolerance occurred in 30 cases (8.7%). CEA with Pruitt-Inahara's shunt was performed in 17 cases with a perioperative neurological adverse event rate of 23.5%. In 13 cases limitations to shunting due to quick onset of coma and/or an unfavorable anatomy were encountered. In these 13 cases the open intervention was immediately converted into endovascular procedure. Technical success was achieved in all the converted to CAS cases (100%), with a perioperative neurological adverse event rate of 7.7% (P=0.35 between the two groups). No significant difference emerges comparing patient's survival between the cases CONCLUSION Nevertheless, the small dimension of this survey, immediate conversion to CAS resulted feasible with a lower risk of neurological adverse events if compared to CEA with shunt, and could be considered as an alternative to CEA when carotid shunt cannot be used safely.

Abstract
Purpose: Type A acute aortic dissection is a surgical emergency, and supra-aortic trunk involvement may be complicated by stroke in 6% to 20% of cases. A 66-year-old Caucasian female patient underwent a composite repair of the ascending aorta for type A aortic dissection. Postoperative period was complicated by episodes of “drop attack.” Doppler ultrasound of supra-aortic trunks revealed an intimal flap occluding right internal carotid artery. Technique: Multiple stenting was performed from carotid bifurcation to internal carotid artery in order to exclude the dissection intimal flap. After endovascular procedure physiatrist considered that motor functional improvement was better than expected, and we support that endovascular resolution of carotid malperfusion led to a better outcome. Conclusion: According to other experience, endovascular procedure resulted as a safe and effective way. Moreover, ultrasound monitoring of supra-aortic trunks in postoperative period is recommended.
