Risk factors for short and long-term great saphenous vein recanalization in patients treated with endovenous radiofrequency ablation.

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.

Rationale and current evidence of aquatic exercise therapy in venous disease: A narrative review.

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.

Role of risk scoring systems in predicting life expectancy after carotid endarterectomy in asymptomatic patients.

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.

Sheath Size Up and Down With Single Proglide - A Technique for Achieving Hemostasis With Use of Large Size Delivery System During Endovascular Graft Placement.

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.

A Computational Fluid-Structure Interaction Study for Carotids With Different Atherosclerotic Plaques.

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.

Carotid artery stenting is safe and effective for symptomatic patients with acute coronary syndrome.

BACKGROUND: Patients with symptomatic carotid stenosis recently treated with percutaneous transluminal coronary angioplasty (PTCA) for acute coronary syndrome (ACS) are always classified as at high risk for surgery, given that they are required uninterrupted dual antiplatelet therapy. In this regard, carotid artery stenting (CAS) may represent a valid alternative. OBJECTIVE: The purpose of this study is to overview CAS outcomes in symptomatic patients with and without ACS. METHODS: One hundred fifty-one consecutive symptomatic patients who underwent CAS between 2010 and 2017 in a single institution were included in this study, of which 66 (43.7%) were identified as having ACS. All patients were followed-up with carotid duplex ultrasound scan and a neurological assessment of symptoms status at 30-day postprocedure and at 3, 6, and 12 months, with annual follow-up after that for 3 years. RESULTS: Among symptomatic ACS patients, common risks factors were active smoking, metabolic syndrome, diabetes, and hypertension. In the short-term follow-up, no significant differences were observed among rates of death, stroke, myocardial infarction (MI), and restenosis, between patients with and without ACS. Mean clinical follow-up was 28.2 (12.3) months. In the long-term follow-up, higher rates of death and MI were recorded in patients with ACS (death: 11.4% vs. 5.4%, p = .04; MI: 11.4% vs. 3.6%, p = .02), owing to the complexity of these patients. CONCLUSIONS: This single-center study suggested that CAS is a safe and effective treatment for patients with symptomatic carotid artery stenosis, who recently underwent PTCA for ACS, requiring uninterrupted dual antiplatelet therapy.

Does metabolic syndrome influence short and long term durability of carotid endarterectomy and stenting?

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.

Three-year follow-up and quality of life of endovenous radiofrequency ablation of the great saphenous vein with the ClosureFast™ procedure: Influence of BMI and CEAP class.

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.

Safety and Efficacy of the New Micromesh-Covered Stent CGuard in Patients Undergoing Carotid Artery Stenting: Early Experience From a Single Centre.

OBJECTIVE/BACKGROUND: Plaque protrusion through stent struts represents one of the principal causes of cerebral embolisation during carotid artery stenting (CAS) and the stent healing period. The aim of this study was to evaluate the safety (technical success) and efficacy (clinical success) of the CGuard stent system - a new nitinol stent covered by a closed-cell polyethylene terephthalate mesh designed to prevent embolic events. METHODS: Eighty-two consecutive patients who underwent CAS with CGuard from June 2015 were included in this study. The same surgeon performed all procedures. Primary endpoints included technical and clinical success. Clinical success was considered to be absence of death, major or minor stroke. The incidence of new ischaemic brain lesions was also evaluated by diffusion weighted magnetic resonance imaging (DW-MRI) in a subgroup of patients as a secondary endpoint. RESULTS: In this study, 82 patients (73.8 ± 8.5 years, 75% male, 19% symptomatic) underwent CAS procedures. Immediate technical success was 100%, with the stenosis diameter reduced from 81.4 ± 4.9% to 11.0 ± 3.5%. There was peri-operative technical and clinical success in 100% of symptomatic patients, and in 98.5% of asymptomatic patients, because of the occurrence of one acute stent thrombosis 4 hours post-CAS followed by a minor stroke. In the post-operative period (30 days), no new events were registered. The most recent 21 patients (24%) underwent DW-MRI in the peri-operative period: new ischaemic brain lesions were recorded in 23.8% of patients and the average lesion volume per patients was 0.039 ± 0.025 cm3. CONCLUSIONS: The technical and clinical outcomes of this single centre study suggest that the CGuard may be a safe and effective device for endovascular treatment of symptomatic and asymptomatic subjects, independent of aortic arch anatomy. Further larger comparative studies are needed to confirm these benefits.

A successful experimental model for intimal hyperplasia prevention using a resveratrol-delivering balloon.

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.

Discussing on the Aortic Coverage in Type B Aortic Dissection Treatment: A Comprehensive Scoping Review.

OBJECTIVE: The objective of this study is to investigate and address the question surrounding the determination of the optimal endograft length of coverage during TEVAR for type B aortic dissection (TBAD), with a particular emphasis on the distal landing zone (DLZ). DATA SOURCES: MEDLINE, Scopus, and Web of Science databases were used. METHODS: The PRISMA-ScR statement was followed. RESULTS: Several variables can contribute to the length of coverage during TEVAR in TBAD patient. Baseline patient's characteristics, TBAD-related features, the type of endoprosthesis, and postoperative graft behaviour may contribute to the choice of coverage. CONCLUSIONS: No robust data have been published regarding the optimal length of TEVAR. Therefore, reporting the percentage of covered aorta and improving computational studies should be valorised to improve postoperative outcomes.

A study protocol for evaluating aortic stiffness modifications in patients treated with endovascular aortic repair.

BACKGROUND: Arterial stiffness, particularly aortic stiffness (AoS), is associated with an increased risk of cardiovascular disease. Endovascular repair for abdominal (EVAR) and thoracic (TEVAR) aortic disease may increase AoS. This study protocol aims to assess changes in AoS before and after interventions for aortic disease. METHODS: Patients scheduled for EVAR or TEVAR during a three-year period will be enrolled. An indirect AoS indicator, carotid-to-femoral pulse wave velocity (cf-PWV) will be measured non-invasively using applanation tonometry and reported with others perioperative data before and after the endovascular treatment. Moreover, cardiological data will be collected through echocardiography. RESULTS: Fifty EVAR and 50 TEVAR will be enrolled. We will primarily analyze changes in cf-PWV. To ensure the reliability of our findings, we will also include supplementary data such as clinical information, morphological data, and functional echocardiographic data. CONCLUSIONS: By examining AoS modifications before and after endovascular aortic repair, this study aims to enhance our understanding of how arterial stiffness changes following endoprosthesis deployment. The findings from the applied protocol are expected to be informative for innovative graft designs with minimized mechanical mismatch with the aortic wall and with improved vascular hemodynamic, aligning with the current trend in improving patient outcomes. Moreover, understanding these modifications is important for predicting and improving long-term cardiovascular outcomes in patients undergoing such interventions.

Carotid artery stenting in patients with acute coronary syndrome: a possible primary therapy for symptomatic carotid stenosis.

PURPOSE: To report the results of carotid artery stenting (CAS) in symptomatic patients (stroke/transient ischemic attack) after recent percutaneous transluminal coronary angioplasty (PTCA) for acute coronary syndrome (ACS). METHODS: Between January 2009 and July 2011, 28 consecutive patients (18 women; mean age 66 years, range 42-82) underwent protected CAS for symptomatic carotid stenosis following recent PTCA that included bare or drug-eluting stents requiring uninterrupted dual antiplatelet therapy. Primary technical success, neurological complications, major adverse cardiovascular events, and death were evaluated at 30 days and over midterm follow-up. RESULTS: Technical success was 96%; 1 patient suffered a nonfatal major stroke (3.5% 30-day stroke rate) during the procedure. During a median 21.6-month follow-up, 4 (14%) patients died of myocardial infarction (all diabetic smokers with ejection fractions <40%), but there were no new neurological events. Estimated survival was 89.3% at 2 years. Further coronary interventions were performed in 2 diabetic patients with a body mass index >34 kg/m(2). CONCLUSION: This preliminary experience demonstrated that CAS is a reasonable, safe, and effective treatment for patients with symptomatic carotid artery stenosis who were recently treated with coronary stents requiring uninterrupted dual antiplatelet therapy.

Radiofrequency ablation of the great saphenous vein with the ClosureFAST™ procedure: mid-term experience on 400 patients from a single centre.

INTRODUCTION: Endovascular obliteration of the great saphenous vein (GSV) has been proposed as an alternative to conventional extirpative treatment of varicose veins. MATERIALS AND METHODS: This report reviewed the initial experience with the ClosureFAST™ procedure in 407 legs over a one-year period. Occlusion of the GSV was seen on 98 % of completion scans and in all patients within 1 week of the procedure. Persistent occlusion was documented in all cases. One had paresthesias and one had skin pigmentation. Three patients had transient superficial thrombophlebitis in a treated segment of a superficial collateral of the GSV. One patient was found to have extension of an asymptomatic, nonocclusive thrombus into the common femoral vein 1 week after the procedure. CONCLUSION: Radiofrequency ablation of the GSV appears to be a safe alternative to conventional stripping and ligation. Randomised clinical trials and longer follow-up periods are required to establish the overall superiority of the procedure in comparison to conventional stripping.

Are all patients with sapheno-femoral junction incompetence the same? An ultrasound analysis to potentially predict recurrence after invasive treatments.

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.

Fluid structure interaction analysis to stratify the behavior of different atheromatous carotid plaques.

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 (WSSsyst, Dsyst, VMSsyst and AEEsyst). RESULTS: WSS resulted significantly higher in CP, whereas D and VMS showed the highest values for LP. Regarding AEEsyst 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.

Carotid artery revascularization using second generation stents versus surgery: a meta-analysis of clinical outcomes.

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).

Relationship between great saphenous vein recanalization, venous symptoms reappearance, and varicose veins recurrence rates after endovenous radiofrequency ablation.

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.
