Abstract
OBJECTIVE The current Instructions for Use (IFU) of cyanoacrylate closure (CAC) is to start initial injection with the catheter tip positioned 5 cm distal to the sapheno-femoral junction (SFJ) to prevent endovenous glue-induced thrombosis (EGIT). However, this defensive design is responsible for the relatively long stump length. Although clinical studies on the long-term recurrence rate are still lacking, the long stump length can predict a higher long-term recurrence rate compared to other surgical methods. The author developed a novel surgical technique that can overcome the weakness of CAC, and the initial outcomes of this technique are described in this article. METHODS This study retrospectively reviewed 25 great saphenous vein (GSV) in 20 patients who underwent CAC for incompetent GSV at our hospital. The procedure from puncturing the GSV to insertion of the catheter is the same as the conventional method. Place the catheter tip 2-3 cm below the SFJ before cyanoacrylate injection. After confirming the position of the SFJ with the longitudinal view of the ultrasound, press the GSV directly above the SFJ transversely with the second to fifth fingertips of the left hand. Then, the ultrasound probe is placed against the distal part of the fingertips, and CA injection is performed while GSV is monitored in real time. RESULTS The mean stump length immediately after surgery was 19.3 (± 7.8) mm, with a range of .0-38.4 mm. The mean stump length after 1 week was 12.3 (± 7.4) mm and the range was .1-35.4 mm. The mean stump length after 1 month was 15.4 (± 10.1) mm, and the range was .0-35.4 mm. There was no case with EGIT or recanalization. CONCLUSIONS The author confirmed the possibility of safely reducing stump length with this novel surgical technique, and expect that this method can help overcome the weakness of CAC.

Pinto P, Fukaya E, Rodriguez LE, Obi A, Ting W, Aziz F, Nguyen K, Murphy EH, Ochoa Chaar CI. Variations and inconsistencies in venous ablation coverage policies between single-state and multistate carriers in the United States. J Vasc Surg Venous Lymphat Disord 2024; 12:101685. [PMID: 37703944 DOI: 10.1016/j.jvsv.2023.07.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 07/02/2023] [Accepted: 07/05/2023] [Indexed: 09/15/2023]
Abstract
BACKGROUND Vein ablation is a common and effective treatment for patients with chronic venous insufficiency. The overuse of vein ablation despite the existence of evidence-based guidelines has resulted in insurance companies developing restrictive policies for coverage that create barriers to appropriate care. This study compares the insurance coverage by single-state carriers (SSCs) and multistate carriers (MSCs), highlighting the variations and inconsistencies in the various policies. METHODS The American Venous Forum Venous Policy Navigator was reviewed for the various policies available in the United States. The policies were divided into SSCs and MSCs. The characteristics of the policies, including the anatomic and hemodynamic criteria for specific veins, duration of conservative treatment, disease severity, symptoms, and types of procedures covered, were compared between the two groups. SAS, version 9.4 (SAS Institute Inc) was used for statistical analysis. RESULTS A total of 122 policies were analyzed and divided between SSCs (n = 85; 69.7%) and MSCs (n = 37; 30.3%). A significant variation was found in the size requirement for great saphenous vein ablation. Although 48% of the policies did not specify a size criterion, the remaining policies indicated a minimal size, ranging from 3 to 5.5 mm. However, no significant differences were found between SSCs and MSCs. Similar findings were encountered for the small and anterior accessory saphenous veins. MSCs were more likely to define a saphenous reflux time >500 ms compared with SSCs (81.1% vs 58.8%; P = .04). A significant difference was found between the SSCs and MSCs in the criteria for perforator ablation in terms of size and reflux time. MSCs were significantly more likely to provide coverage for mechanochemical ablation than were SSCs (24.3% vs 8.2%; P = .03). SSCs were more likely to require ≥12 weeks of compression stocking therapy than were MSCs (76.5% vs 48.7%; P = .01). No significant differences were found in the clinical indications between the two groups; however, MSCs were more likely to mention major hemorrhage than were SSCs. CONCLUSIONS The results of this study highlight the variations in policies for venous ablation, in particular, the striking inconsistencies in size criteria. MSCs were more likely to cover mechanochemical ablation and require a shorter duration of conservative therapy before intervention compared with SSCs. Evidence-based guidance is needed to develop more coherent policies for venous ablation coverage.

A Systematic Review and Meta-Analysis of Randomised Controlled Trials Comparing Thermal Versus Non-Thermal Endovenous Ablation in Superficial Venous Incompetence. Eur J Vasc Endovasc Surg 2023; 66:687-695. [PMID: 37295602 DOI: 10.1016/j.ejvs.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 05/07/2023] [Accepted: 06/02/2023] [Indexed: 06/12/2023]
Abstract
OBJECTIVE The objective was to compare technical success, complications, and quality of life after thermal vs. non-thermal endovenous ablation for the treatment of superficial venous incompetence. DATA SOURCES Electronic bibliographic sources (Google Scholar, Pubmed, Cochrane Database, Scopus, Web of Science, and Embase). REVIEW METHODS A systematic review and meta-analysis of randomised controlled trials was conducted using terms to identify relevant studies to be included. The primary outcome was vein occlusion rate at up to four weeks and one to two years from procedure. Secondary outcome measures included peri-procedural pain, nerve injury, endothermal heat induced thrombosis, and quality of life. RESULTS Eight randomised controlled trials met the selection criteria. These comprised a total of 1 956 patients, of whom 1 042 underwent endovenous thermal ablation and 915 underwent endovenous non-thermal ablation. There was no statistically significant difference in occlusion rate at all time points. Relative risk at four weeks and one to two years was 0.99 (95% CI 0.96 - 1.02) and 0.95 (95% CI 0.88 - 1.01), respectively. Non-thermal ablation was tolerated better and had less risk of nerve injury. There was no statistically significant difference in risk of endothermal heat induced thrombosis (EHIT). There was improvement in quality of life scores post-procedure but there was no statistically significant difference in thermal vs. non-thermal ablation. The quality of evidence assessed using GRADE methodology showed high quality for occlusion rate at four weeks and one to two years, moderate quality for nerve injury and peri-procedural pain, and low quality for EHIT. CONCLUSION Vein occlusion rates after thermal vs. non-thermal endovenous ablation are similar. In the early post-operative period, non-thermal endovenous ablation demonstrated the advantages of less pain and less risk of nerve injury. Improvement in quality of life after both thermal and non-thermal endovenous ablation is similar.

Abstract
OBJECTIVES In this study, we present the complication data of patients we treated for chronic venous insufficiency (CVI) with cyanoacrylate adhesive closure (CAC) therapy for 2 years. METHODS Complications of 382 CAC procedures performed by the same surgeon were reviewed retrospectively. RESULTS Independent of patients, depending on the payment system of the state; two hundred twenty-three (58.4%) of 382 procedures were performed using the Venex system, and the Variclose system was used in 159 (41.6%) patients. A phlebitis-like reaction occurred in 46 (12%) patients, induration in 18 (4.7%) patients, hyperpigmentation in five (1.3%) patients, abscesses in four (1%) patients, cellulitis in three (0.8%) patients, and granuloma in one (0.3%) patient. In addition, as serious complications, deep vein thrombosis (DVT) developed in three patients and pulmonary embolism in one of these patients. Interestingly, temporary blindness was also observed in one patient. CONCLUSIONS Although CAC therapy is a reliable method, its complications should not be ignored. Its use by experienced surgeons reduces the risk of complications.

Abstract
This systematic review and network meta-analysis investigated the clinical efficacy and safety of chemical agent injections in patients with varicose veins. PubMed, Embase, and Cochrane databases were searched for eligible studies where patients administered endovascular agents comprised an intervention group, and patients administered other interventions comprised the comparison group. The endovascular agents included foam and liquid form sclerotherapy or cyanoacrylate glue. The other interventions in this study included surgery, endovenous laser ablation (EVLA), radiofrequency ablation (RFA), and placebo. A network meta-analysis for treatment effectiveness was performed. In addition, we illustrated the P-score lines of success rate and complication rate sorted by the P-score. Our results showed that at all postprocedural time intervals, cyanoacrylate glue therapy exhibited a significantly higher success rate compared with foam and liquid sclerotherapy. According to the plot of P-score lines, cyanoacrylate glue had an overall tendency of higher success rate and lower complication rate compared with foam and liquid sclerotherapy. Comparing with the other invasive treatments, cyanoacrylate glue may be non-inferior and could be considered as an option for treating varicose veins. However, the clinical benefits and safety of endovascular agents for the treatment of varicose veins require further corroboration through randomized control trials.

Abstract
OBJECTIVE Cyanoacrylate glue closure was first used in humans 10 years ago to treat venous reflux of the axial veins. Studies have since shown its clinical efficacy in vein closure. However, great need exists to elucidate further the types of specific adverse reactions that cyanoacrylate glue can cause for better patient selection and to minimize these events. In the present study, we systematically reviewed the literature to identify the types of reported reactions. In addition, we explored the pathophysiology contributing to these reactions and proposed the mechanistic pathway with inclusion of actual cases. METHODS We searched the literature for reports of reactions following cyanoacrylate glue use in patients with venous diseases between 2012 and 2022. The search was performed using MeSH (medical subject headings) terms. The terms included cyanoacrylate, venous insufficiency, chronic venous disorder, varicose veins, vein varicosities, venous ulcer, venous wound, CEAP (clinical, etiologic, anatomic, pathophysiologic), vein, adverse events, phlebitis, hypersensitivity, foreign body granuloma, giant cell, endovenous glue-induced thrombosis, and allergy. The search was limited to the literature reported in English. These studies were evaluated for the type of product used and the reactions noted. A systematic review, in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) method, was performed. Covidence software (Melbourne, VC, Australia) was used for full-text screening and data extraction. Two reviewers reviewed the data, and the content expert served as the tiebreaker. RESULTS We identified 102, of which, 37 reported on cyanoacrylate use other than in the context of chronic venous diseases and were excluded. Fifty-five reports were determined appropriate for data extraction. The adverse reactions to cyanoacrylate glue were phlebitis, hypersensitivity, foreign body granuloma, and endovenous glue-induced thrombosis. CONCLUSIONS Although cyanoacrylate glue closure for venous reflux is generally a safe and clinically effective treatment choice for patients with symptomatic chronic venous disease and axial reflux, some adverse events could be specific to the properties of the cyanoacrylate product. We propose mechanisms for how such reactions can occur based on histologic changes, published reports, and case examples; however, further exploration is necessary to confirm these theories.

Abstract
The Society for Vascular Surgery, American Venous Forum, and American Vein and Lymphatic Society collaborated to update the 2011 Society for Vascular Surgery/American Venous Forum clinical practice guidelines and provide new evidence-based recommendations on critical issues affecting the care of patients with varicose veins. Each recommendation is based on a recent, independent systematic review and meta-analysis of the diagnostic tests and treatments options for patients with lower extremity varicose veins. Part I of the guidelines includes evidence-based recommendations for the evaluation of patients with CEAP (Clinical Class, Etiology, Anatomy, Pathology) class 2 varicose vein using duplex ultrasound scanning and other diagnostic tests, open surgical treatment (ligation and stripping) vs endovenous ablation techniques, thermal vs nonthermal ablation of the superficial truncal veins, and management of incompetent perforating veins in CEAP class 2 disease. We have also made recommendations on the concomitant vs staged treatment of varicose tributaries using phlebectomy or liquid or foam sclerotherapy (with physician-compounded foam or commercially prepared polidocanol endovenous microfoam) for patients undergoing ablation of incompetent superficial truncal veins.

Abstract
Introduction Great saphenous vein diameter (GSV) of >8 mm was predictor of recanalization following Venaseal cyanoacrylate treatment. The aim of this study was to report our modified protocol with a single extra-drop for treatment for GSV>8 mm, and comparative duplex results in closure rates. Methods Patients in our single-centre registry treated with Venaseal were followed up by serial duplex examinations at week 1 and month(s)- 1, 6, 12, 18, 24, and then annually. The primary endpoint was successful obliteration of the GSV, secondary endpoints were closure distance from Saphenofemoral junction (SFJ), presence of endovenous glue-induced thrombosis (EGIT) or deep vein thrombosis. Results A total of 243 legs in 123 consecutive patients with duplex-proven SFJ/GSV incompetence were included in this study between September 2014 and October 2020. The median duplex follow-up period of this cohort of patients was 24 (range 0.2–58) months. Comparing closure rates in GSV diameter ≥8 mm treated with normal protocol, the ‘extra-drop protocol’ significantly improved closure rates ( p = .034). However, the closure rates of ≥8 mm GSV treated with ‘extra-drop protocol’ was still not as good as GSV <8 mm ( p < .001). There were no statistically significant differences in the stump distance between the three groups and no difference in the occurrence of EGIT. There were no deep vein thrombosis. Conclusion Our experience showed that VenaSeal cyanoacrylate worked best in GSV<8 mm diameter. Even in GSV diameter of ≥8 mm which has a higher recanalization rate on follow-up duplex, our modified extra-drop protocol significantly improved the closure rates, and did not predispose to development of EGIT.

Abstract
INTRODUCTION This study aims to evaluate the long-term results regarding the effectiveness and reliability of endovenous laser ablation (EVLA), endovenous n-butyl cyanoacrylate (NBCA) application and radiofrequency ablation (RFA) methods in the management of Chronic venous insufficiency (CVI). METHODS Charts of patients treated with EVLA, NBCA and RFA methods for CVI between January 1st, 2014 and January 1st, 2017, were reviewed. Records were made of personal information including sex, age, body mass index (BMI), American Society of Anesthesiologists score (ASA) and admission symptoms. Great saphenous vein (GSV) diameter, score of CEAP (Clinical, Etiology, Anatomy and Pathophysiology) classification, and Venous Clinical Severity Score (VCSS) were also noted. All patients were followed up with physical examination and CDUS at the first week, and 6th and 12th months after the procedures. After 12th month, follow-ups were annual. RESULTS Enrolled in the study were a total of 232 patients who underwent lower limb CVI procedures (77 patients with EVLA, 73 patients with NBCA and 82 patients with RFA). The mean follow-up time was 67.5±4.7 months. Time of procedure was significantly shorter in patients treated with NBCA (13.5 minutes) in comparison of patients treated with EVLA (31.7 minutes) and RFA (27.9 minutes) (p= 0.001). Pain score was highest in EVLA group (p= 0.001). Significantly higher complication rates and longer time to return daily activity was recorded in those undergoing EVLA procedure (p= 0.001). Post hoc analysis revealed comparable occlusion success among groups on post-operative first day, and at 6th month, first year and second year. However, significantly better success of occlusion rates were found for RFA in comparison of EVLA in third and fifth-years follow-ups (p= 0.024 and p= 0.011). The success of NBCA and RFA was similar in third and fifth-years follow-ups (p= 0.123 vs p= 0.330) CONCLUSION: Outcomes showed similar levels of early postoperative occlusion success among all three CVI treatment techniques, but RFA has a significantly higher success rate over EVLA in the third and fifth-year follow-ups. Additionally, NBCA and RFA procedures achieved comparable long-term success. EVLA was associated with significantly higher complication rates and pain scores, and longer time to return daily activities, while NBCA procedure had a significantly shorter operation time than the other procedures.

Abstract
OBJECTIVES The aim of this study was to assess occlusion rates of saphenous veins treated with the VariClose vein sealing system. METHODS A retrospective analysis including a total of 64 patients from four centres from the Czech Republic. Occlusion was defined as a non-compressible vein with absence of flow with exception to the first 3 cm from the saphenofemoral or saphenopopliteal junction on duplex ultrasound. RESULTS In 64 patients a total of 79 veins were treated. Technical success of the procedure was achieved in 74 (94%) of cases. The mean follow-up was 5.5 months. The closure rates calculated by the Kaplan-Meier method at 1, 3, 6 and 12 months were 94%, 85%, 69% and 36%, respectively, and there were no significant differences between centers. The average difference in VCSS score before and after the procedure was 1.8. CONCLUSIONS The present study demonstrated surprisingly worse occlusion rates than the current literature.

Daylan A, İslamoğlu F. Comparative analysis of the results of cyanoacrylate ablation and radiofrequency ablation in the treatment of venous insufficiency. J Vasc Surg Venous Lymphat Disord 2021; 10:661-668.e2. [PMID: 34536569 DOI: 10.1016/j.jvsv.2021.09.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 09/01/2021] [Indexed: 12/16/2022]
Abstract
BACKGROUND Varicose vein treatment has shifted to less invasive techniques owing to the complications associated with traditional treatment. The present study was designed to compare the effectiveness of cyanoacrylate ablation (CAA) with radiofrequency ablation (RFA). METHODS Patients who had undergone RFA vs CAA (634 vs 246 patients) to treat great saphenous vein (GSV) insufficiency during a 5-year period were included in the present study. The preoperative and postoperative CEAP (clinical, etiologic, anatomic, pathophysiologic) class, symptoms, recurrence, and Doppler ultrasound findings were compared. RESULTS All the veins in both groups were occluded at day 5. The 1-month closure rates were 97.3% and 98.7% for RFA and CAA, respectively. The overall postoperative closure rates at 5 years were 93.1% and 91.1% for RFA and CAA, respectively. The postoperative symptoms, CEAP class, and Doppler ultrasound findings were similar in both groups. The 5-year symptom-free survival rates were 73.5% and 72.0% in the RFA and CAA groups, respectively. The venous clinical severity scores had decreased from 5.9 ± 1.2 to 0.9 ± 0.8 and 5.8 ± 0.9 to 0.8 ± 0.6 in the RFA and CAA groups, respectively. The Aberdeen varicose vein questionnaire scores had decreased from 19.7 ± 5.5 to 4.8 ± 1.5 in the RFA group and from 18.9 ± 5.8 to 4.9 ± 1.4 in the CAA group. CONCLUSIONS CAA seems to be the ideal treatment for GSV insufficiency because it is suitable for most patients and is nonthermal and nontumescent, with satisfactory results comparable to those with RFA. Long-term outcomes and cost analyses from larger series are required to confirm our findings.

Abstract
The use of cyanoacrylate embolization has increased in interest as a safe, effective, and minimally invasive method to treat symptomatic saphenous reflux. The procedure is generally well tolerated by patients, and complications such as phlebitis are minor and usually self-limiting. Postprocedural infections have been described but occur infrequently and usually in the early postoperative course. In the present case report, we have described a late-onset infective thrombophlebitis of the great saphenous vein after cyanoacrylate embolization, requiring surgical excision of the treated vein.

Abstract
BACKGROUND Several diagnostic tests and treatment options for patients with lower extremity varicose veins have existed for decades. The purpose of this systematic review was to summarize the latest evidence to support the forthcoming updates of the clinical practice guidelines on the management of varicose veins for the Society for Vascular Surgery (SVS), the American Venous Forum (AVF) and the American Vein and Lymphatic Society. METHODS We searched multiple databases for studies that addressed four clinical questions identified by the AVF and the SVS guideline committee about evaluating and treating patients with varicose veins. Studies were selected and appraised by pairs of independent reviewers. A meta-analysis was conducted when feasible. RESULTS We included 73 original studies (45 were randomized controlled trials) and 1 systematic review from 12,915 candidate references. Moderate certainty of evidence supported the usefulness of duplex ultrasound (DUS) examination as the gold standard test for diagnosing saphenous vein incompetence in patients with varicose veins and chronic venous insufficiency (clinical, etiological, anatomic, pathophysiological classification [CEAP] class C2-C6). High ligation and stripping (HL/S) was associated with higher anatomic closure rates at 30 days and 5 years when compared with radiofrequency ablation and ultrasound-guided foam sclerotherapy (UGFS) (moderate certainty), while no significant difference was seen when compared with endovenous laser ablation (EVLA) at 5 years. UGFS was associated with an increased risk of recurrence compared with HL/S. EVLA was associated with lower anatomic closure rates at 30 days than cyanoacrylate closure (CAC) and higher rates at one and 5 years when compared with UGFS. Thermal interventions were associated with lower generic quality of life scores and an increased risk of adverse events when compared with CAC or n-butyl cyanoacrylate (low certainty). Thermal interventions were associated with a lower risk of recurrent incompetence when compared with UGFS and an increased risk of recurrent incompetence than CAC. The evidence for great saphenous vein ablation alone to manage perforator disease was inconclusive. CONCLUSIONS The current systematic review summarizes the evidence to develop and support forthcoming updated SVS/AVF/American Vein and Lymphatic Society clinical practice guideline recommendations. The evidence supports duplex scanning for evaluating patients with varicose veins and confirms that HL/S resulted in similar long-term saphenous vein closure rates as EVLA and in better rates than radiofrequency ablation and UGFS. Thermal interventions were associated with inferior generic quality of life scores than nonthermal interventions, but had a lower risk of recurrent incompetence than UGFS. The recommendations in the guidelines should consider this information as well as other factors such as patients' values and preferences, anatomic considerations of individual patients, and surgical expertise.

Cost-effectiveness Analysis of Current Varicose Veins Treatments. J Vasc Surg Venous Lymphat Disord 2021; 10:504-513.e7. [PMID: 34450353 DOI: 10.1016/j.jvsv.2021.05.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 05/02/2021] [Indexed: 02/06/2023]
Abstract
OBJECTIVE To analyze the effectiveness and cost-effectiveness of technologies for treatment of varicose veins over 5 years - conservative care (CONS), surgery (HL/S), ultrasound guided foam sclerotherapy (UGFS), endovenous laser ablation (EVLA), and radiofrequency ablation (RFA), mechanochemical ablation (MOCA) and cyanoacrylate glue occlusion (CAE). METHODS A systematic review was updated and used to construct a Markov decision model. Outcomes were re-intervention on the truncal vein, re-treatment of residual varicosities and quality-adjusted life years (QALY) and costs over five years. RESULTS UGFS has a significantly greater re-intervention rate than other procedures, while there is no significant difference between the other procedures. The cost per QALY of EVLA versus UGFS in our base-case model is £16966 ($23700) per QALY, which is considered cost-effective in the UK. RFA, MOCA and CAE have greater procedure costs than EVLA with no evidence of greater benefit for patients. CONCLUSIONS EVLA is the most cost-effective therapeutic option, with RFA a close second, in adult patients requiring treatment in the upper leg for incompetence of the GSV. MOCA, UGFS, CAE, CONS and HL/S are not cost-effective at current prices in the UK National Health Service. MOCA and CAE appear promising but further evidence on effectiveness, re-interventions and health-related quality of life is needed, as well as how cost-effectiveness may vary across settings and reimbursement systems.

Abstract
OBJECTIVE The treatment of varicose veins has shifted from conventional surgical stripping (SS) to minimally invasive endovenous modalities. Cyanoacrylate closure (CAC) with the VenaSeal system (Medtronic, Dublin, Ireland) has increased in popularity owing to its nonthermal and nontumescent technique. The purpose of the present study was to compare the clinical outcomes of CAC and SS for the treatment of incompetent great saphenous veins. METHODS An open-label, multicenter, prospective, randomized controlled trial was conducted. The subjects were randomized to either the CAC or SS procedure. The primary endpoint of the present study was to evaluate complete closure of the target vein at 3 months. Target vein occlusion was assessed on the third day and 1, 3, 6, and 12 months postoperatively using duplex ultrasound. The pain and ecchymosis grades were also assessed. Additionally, the clinical outcomes, such as the venous clinical severity score and Aberdeen Varicose Vein Questionnaire score, were assessed. RESULTS Three-month follow-up data were obtained for all 126 enrolled and randomized subjects (63 with CAC and 63 with SS). At 3 months, complete target vein closure was observed in both groups. The postoperative pain score was significantly better in the CAC group than in the SS group (0.3 ± 0.6 in the CAC group and 1.1 ± 1.5 in the SS group; P < .001). In addition, the mean ecchymosis grade was 0.3 ± 0.5 in the CAC group and 1.1 ± 1.1 in the SS group (P < .001). The venous clinical severity score and quality of life had improved equally in both groups. The adverse events after both procedures were mostly minor complications (9 events in CAC group and 20 events in SS group). Major complications occurred in one patient who had undergone the SS procedure. CONCLUSIONS The CAC and SS procedures were both associated with complete occlusion of the target vein at 3 months. The postoperative pain and ecchymosis grades were significantly lower in the CAC group. Other differences between the two groups included the frequency and nature of the complications. The results showed that CAC has high success with few complications.

Abstract
BACKGROUND Great saphenous vein (GSV) incompetence, causing varicose veins and venous insufficiency, makes up the majority of lower-limb superficial venous diseases. Treatment options for GSV incompetence include surgery (also known as high ligation and stripping), laser and radiofrequency ablation, and ultrasound-guided foam sclerotherapy. Newer treatments include cyanoacrylate glue, mechanochemical ablation, and endovenous steam ablation. These techniques avoid the need for a general anaesthetic, and may result in fewer complications and improved quality of life (QoL). These treatments should be compared to inform decisions on treatment for varicosities in the GSV. This is an update of a Cochrane Review first published in 2011. OBJECTIVES To assess the effects of endovenous laser ablation (EVLA), radiofrequency ablation (RFA), endovenous steam ablation (EVSA), ultrasound-guided foam sclerotherapy (UGFS), cyanoacrylate glue, mechanochemical ablation (MOCA) and high ligation and stripping (HL/S) for the treatment of varicosities of the great saphenous vein (GSV). SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and AMED databases, and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 2 November 2020. We undertook reference checking to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) treating participants for varicosities of the GSV using EVLA, RFA, EVSA, UGFS, cyanoacrylate glue, MOCA or HL/S. Key outcomes of interest are technical success, recurrence, complications and QoL. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, applied Cochrane's risk of bias tool, and extracted data. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) and assessed the certainty of evidence using GRADE. MAIN RESULTS We identified 11 new RCTs for this update. Therefore, we included 24 RCTs with 5135 participants. Duration of follow-up ranged from five weeks to eight years. Five comparisons included single trials. For comparisons with more than one trial, we could only pool data for 'technical success' and 'recurrence' due to heterogeneity in outcome definitions and time points reported. All trials had some risk of bias concerns. Here we report the clinically most relevant comparisons. EVLA versus RFA Technical success was comparable up to five years (OR 0.98, 95% CI 0.41 to 2.38; 5 studies, 780 participants; moderate-certainty evidence); over five years, there was no evidence of a difference (OR 0.85, 95% CI 0.30 to 2.41; 1 study, 291 participants; low-certainty evidence). One study reported recurrence, showing no clear difference at three years (OR 1.53, 95% CI 0.78 to 2.99; 291 participants; low-certainty evidence), but a benefit for RFA may be seen at five years (OR 2.77, 95% CI 1.52 to 5.06; 291 participants; low-certainty evidence). EVLA versus UGFS Technical success may be better in EVLA participants up to five years (OR 6.13, 95% CI 0.98 to 38.27; 3 studies, 588 participants; low-certainty evidence), and over five years (OR 6.47, 95% CI 2.60 to 16.10; 3 studies, 534 participants; low-certainty evidence). There was no clear difference in recurrence up to three years and at five years (OR 0.68, 95% CI 0.20 to 2.36; 2 studies, 443 participants; and OR 1.08, 95% CI 0.40 to 2.87; 2 studies, 418 participants; very low-certainty evidence, respectively). EVLA versus HL/S Technical success may be better in EVLA participants up to five years (OR 2.31, 95% CI 1.27 to 4.23; 6 studies, 1051 participants; low-certainty evidence). No clear difference in technical success was seen at five years and beyond (OR 0.93, 95% CI 0.57 to 1.50; 5 studies, 874 participants; low-certainty evidence). Recurrence was comparable within three years and at 5 years (OR 0.78, 95% CI 0.47 to 1.29; 7 studies, 1459 participants; and OR 1.09, 95% CI 0.68 to 1.76; 7 studies, 1267 participants; moderate-certainty evidence, respectively). RFA versus MOCA There was no clear difference in technical success (OR 1.76, 95% CI 0.06 to 54.15; 3 studies, 435 participants; low-certainty evidence), or recurrence (OR 1.00, 95% CI 0.21 to 4.81; 3 studies, 389 participants; low-certainty evidence). Long-term data are not available. RFA versus HL/S No clear difference in technical success was detected up to five years (OR 5.71, 95% CI 0.64 to 50.81; 2 studies, 318 participants; low-certainty evidence); over five years, there was no evidence of a difference (OR 0.88, 95% CI 0.29 to 2.69; 1 study, 289 participants; low-certainty evidence). No clear difference in recurrence was detected up to three years (OR 0.93, 95% CI 0.58 to 1.51; 4 studies, 546 participants; moderate-certainty evidence); but a possible long-term benefit for RFA was seen (OR 0.41, 95% CI 0.22 to 0.75; 1 study, 289 participants; low-certainty evidence). UGFS versus HL/S Meta-analysis showed a possible benefit for HL/S compared with UGFS in technical success up to five years (OR 0.32, 95% CI 0.11 to 0.94; 4 studies, 954 participants; low-certainty evidence), and over five years (OR 0.09, 95% CI 0.03 to 0.30; 3 studies, 525 participants; moderate-certainty evidence). No clear difference was detected in recurrence up to three years (OR 1.81, 95% CI 0.87 to 3.77; 3 studies, 822 participants; low-certainty evidence), and after five years (OR 1.24, 95% CI 0.57 to 2.71; 3 studies, 639 participants; low-certainty evidence). Complications were generally low for all interventions, but due to different definitions and time points, we were unable to draw conclusions (very-low certainty evidence). Similarly, most studies evaluated QoL but used different questionnaires at variable time points. Rates of QoL improvement were comparable between interventions at follow-up (moderate-certainty evidence). AUTHORS' CONCLUSIONS Our conclusions are limited due to the relatively small number of studies for each comparison and differences in outcome definitions and time points reported. Technical success was comparable between most modalities. EVLA may offer improved technical success compared to UGFS or HL/S. HL/S may have improved technical success compared to UGFS. No evidence of a difference was detected in recurrence, except for a possible long-term benefit for RFA compared to EVLA or HL/S. Studies which provide more evidence on the breadth of treatments are needed. Future trials should seek to standardise clinical terminology of outcome measures and the time points at which they are measured.

Abstract
BACKGROUND A variety of endovascular and open surgical interventions exist to treat great saphenous vein reflux. However, comparisons of treatment outcomes have been inconsistent. METHODS A systematic review and network meta-analysis of RCTs was performed to compare rates of incomplete stripping or non-occlusion of the great saphenous vein with or without reflux (anatomical failure) at early, mid- and long-term follow-up; and secondary outcomes (reintervention and clinical recurrence) among intervention groups. The surface under the cumulative ranking curve (SUCRA) method was used to estimate the probability of the intervention with the lowest anatomical failure rates. RESULTS Some 72 RCTs were included. Comparisons of endothermal techniques with open surgery were mostly not significantly different, except for endovenous laser ablation (EVLA), which had higher long-term anatomical failure rates (pooled risk ratio (RR) 1.87, 95 per cent c.i. 1.14 to 3.07). Mechanochemical ablation had higher anatomical failure rates than radiofrequency ablation (RFA) (pooled RR 2.77, 1.38 to 5.53), and cyanoacrylate closure (CAC) had a RR 0.56 (0.34 to 0.93) times lower than either RFA or EVLA at the early term. Ultrasound-guided foam sclerotherapy had a higher risk of anatomical failure and reintervention than open surgery, with the lowest SUCRA value, and CAC was ranked first, third and first for best intervention for anatomical failure at early, mid and long term respectively. However, clinical recurrence rates were not significantly different between all comparisons. CONCLUSION Mechanochemical ablation and ultrasound-guided foam sclerotherapy performed poorly, with higher anatomical failure rates in the long term. The other treatment modalities had similar rates of anatomical failure in the short and mid term.

Abstract
BACKGROUND Chronic venous disease is a debilitating condition involving great saphenous vein (GSV) incompetence. OBJECTIVE To investigate the efficacy and effectiveness of cyanoacrylate embolization (CAE) versus radiofrequency ablation (RFA) in patients with incompetent GSVs. MATERIALS AND METHODS PubMed, Embase, and the Cochrane library were searched. The primary outcomes were the Venous Clinical Severity Score (VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), closure rate, and visual analog scale (VAS) for pain. RESULTS This meta-analysis included 378 and 590 patients who underwent CAE and RFA, respectively. Cyanoacrylate embolization was comparable with RFA in VCSS (weighted mean difference [WMD] = -0.03, 95% confidence interval [CI]: -0.18 to 0.12, p = .686), AVVQ (WMD = -0.08, 95% CI: -0.38 to 0.21, p = .570), closure rate (odds ratio [OR] = 0.61, 95% CI: 0.18-2.01, p = .414), and VAS (standardized mean difference [SMD] = 0.24, 95% CI: -0.59 to 1.06, p = .523). There were no significant differences between CAE and RFA regarding the occurrence of phlebitis (OR = 1.22, 95% CI: 0.70-2.13, p = .479) and pigmentation (OR = 0.48, 95% CI: 0.18-1.31, p = .153), but CAE had a lower risk of ecchymosis (OR = 0.45, 95% CI: 0.25-0.81, p = .007) and paresthesia (OR = 0.16, 95% CI: 0.03-0.99, p = .049). CONCLUSION Cyanoacrylate embolization and RFA demonstrated no significant differences in VCSS, AVVQ, closure rate, and pain score for patients with incompetent GSVs. Patients in the CAE group had a lower risk of ecchymosis and paresthesia compared with the RFA group.

Abstract
BACKGROUND Varicose veins are part of the spectrum of chronic venous disease and are a sign of underlying chronic venous insufficiency. Treatments to address varicose veins include surgical vein removal under general anesthesia, or endovenous laser (EVLA) or radiofrequency ablation (RFA) under tumescent anesthesia. Two newer nonthermal endovenous procedures can close veins without any tumescent anesthesia, using either mechanochemical ablation (MOCA, a combination of mechanical and chemical techniques) or cyanoacrylate adhesive closure (CAC). We conducted a health technology assessment of these nonthermal endovenous procedures for people with symptomatic varicose veins, which included an evaluation of effectiveness, safety, cost-effectiveness, the budget impact of publicly funding MOCA and CAC, and patient preferences and values. METHODS We performed a systematic literature search of the clinical evidence. We assessed the risk of bias of each included study using the Cochrane Risk of Bias or RoBANS tool, and the quality of the body of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. Meta-analysis was conducted using Review Manager 5.2, where appropriate.We performed a systematic economic literature search and conducted a cost-utility analysis with a 5-year time horizon from the perspective of Ontario Ministry of Health. In our primary economic evaluation, we assessed the cost-effectiveness of nonthermal endovenous procedures (CAC and MOCA) compared with surgical vein stripping and thermal endovenous therapies (EVLA and RFA). We also analyzed the budget impact of publicly funding nonthermal and thermal endovenous therapies for adults with symptomatic varicose veins in Ontario over the next 5 years. Costs are expressed in 2020 Canadian dollars.To contextualize the potential value of nonthermal endovenous treatments, we spoke with 13 people with varicose veins who had sought various treatment options. We conducted phone interviews and qualitatively analyzed their responses regarding their care journey and the impact of different treatment options; the only nonthermal treatment that participants had experience with was CAC. RESULTS We included 19 primary studies reported in 25 publications comparing either MOCA or CAC with at least one other invasive treatment for symptomatic varicose veins. No studies compared MOCA with CAC. Based on evidence of low to moderate quality, MOCA resulted in slightly poorer technical outcomes (vein closure and recanalization) than thermal endovenous ablation procedures. However, clinical outcomes, quality of life improvement, and patient satisfaction were similar compared with RFA (GRADE: Very low to Moderate) and EVLA (GRADE: High). Cyanoacrylate adhesive closure resulted in little to no difference in technical outcomes, clinical outcomes, and quality of life improvement compared with RFA and EVLA (GRADE: Moderate). Patient satisfaction may also be similar (GRADE: Low). Recovery time was slightly reduced with nonthermal endovenous procedures compared with thermal ablation (GRADE: Moderate). The effect of CAC compared with surgical vein stripping is very uncertain (GRADE: Very low). Major complications of any procedure were rare, with minor complications occurring as expected and resolving.We included two European studies in the economic evidence review that were partially applicable to the Ontario context. Both studies found that thermal ablation procedures (RFA, EVLA, or steam vein sclerosis) were the most cost-effective treatments, compared with surgical vein stripping and nonthermal therapies. Our cost-utility analysis showed that surgical vein stripping is the least effective and most costly treatment among five treatments for varicose veins. Differences in quality-adjusted life-years (QALYs) between endovenous treatments (CAC, MOCA, RFA, and EVLA) were small. When the willingness-to-pay (WTP) value was $50,000 per QALY gained, the probabilities of being cost-effective were 55.6%, 18.8%, 15.6%, 10.0%, and 0%, for EVLA, CAC, MOCA, RFA, and surgical vein stripping, respectively. When the WTP was $100,000 per QALY gained, the probabilities of being cost-effective were 40.2%, 30.0%, 17.7%, 12.1%, and 0%, for EVLA, CAC, RFA, MOCA, and surgical vein stripping, respectively. Publicly funding endovenous procedures (both nonthermal and thermal) would increase the total volume of treatments, resulting in a total 5-year budget impact of around $17 million.People with varicose veins with whom we spoke reported positively on their experiences with the CAC procedure and its outcomes. They also described geographic and financial barriers to accessing the range of available treatment options. CONCLUSIONS Cyanoacrylate adhesive closure and MOCA produced similar patient-important outcomes, and slightly shorter recovery compared with thermal ablation. Cyanoacrylate adhesive closure yielded similar anatomical outcomes as thermal endovenous ablation, but the technical outcomes of MOCA were slightly poorer.Compared with surgical vein stripping, all endovenous treatments were more effective and less expensive. If we were to look at the most cost-effective strategy (at WTP less than $100,000 per QALY), EVLA is most likely to be cost-effective. Assuming an 80% increase in the number of eligible people over the next 5 years, we estimate that publicly funding nonthermal and thermal endovenous treatments for varicose veins in Ontario would range from $2.59 million in year 1 to $4.35 million in year 5, and that the total 5-year budget impact would be around $17 million.For people with varicose veins, the CAC procedure was seen as a positive treatment method that reduced their symptoms and improved their quality of life.

Abstract
BACKGROUND One of the three commercially available cyanoacrylate venous glues used for the treatment of saphenous vein insufficiency is the VariClose® vein sealing system. Previous studies have documented a high rate of occlusion and minimal postoperative complications. The aim of this study was to compare occlusion rates and clinical outcomes of endovenous laser treatment with the VariClose® vein sealing system in the treatment of truncal vein insufficiency. PATIENTS AND METHODS Retrospective non-randomized single center study with prospectively collected data comparing endovenous laser treatment and VariClose® procedures between April 2018 and November 2019. RESULTS VariClose® was used in 27 patients (30 veins) and endovenous laser treatment in 42 patients (51 veins). The occlusion rate at one, three, and six months were 96%, 85%, and 65% for VariClose® procedures and 100%, 100%, and 97% for endovenous laser treatment procedures (p = 0.01), respectively. Reduction of VCSS scores before treatment and at the last postoperative follow-up visit in the VariClose® group dropped by an average of 1.8 ± 1.6 and in the endovenous laser treatment by an average of 3.3 ± 2.9 (p = 0.01). CONCLUSION VariClose® vein sealing system is inferior to endovenous laser treatment as a treatment option for varicose veins as it has a higher recanalization rate.

Abstract
OBJECTIVES The aim of this study was to systemically review and analyze the efficacy of cyanoacrylate ablation (CA) in comparison with endovenous thermal ablation (ETA) for the treatment of incompetent saphenous veins. METHODS A systematic literature search was conducted using databases of Pubmed, Embase, and Cochrane Library from the times of their inception to April 2020. Studies were selected based on inclusion and exclusion criteria after assessing the risk of bias in comparative studies with Cochrane and rating quality of evidence with the GRADE methodology. The meta-analysis was carried out using the Review Manager 5.4 program to conduct homogeneity tests. RESULTS One cohort study and three randomized controlled trials (RCT), including a total of 1457 participants were included in the meta-analysis. ETA included endovenous laser ablation (ELVA) and radiofrequency ablation (RFA) in the selected studies. Comparison between CA and a combination of EVLA and RFA or RFA alone were carried out in two of RCTs, while comparison between CA with EVLA was conducted in one RCT and the cohort study. There was no statistical difference in closure rates between CA and ETA after pooled analysis. Similar symptom alleviation observed between different groups. However, the CA group showed a lower ecchymosis rate than RFA and a significantly lower incidence of adverse events, such as ecchymosis, phlebitis and paresthesia, than EVLA. Compared with ETA, the patients received CA treatment exhibited lower pain scores in a shorter procedure duration without needing compression stocking, returned to normal life sooner, and had significantly better quality of care. There was no significant difference in the number needed to treat for additional therapy after three months of follow-up between groups. CONCLUSIONS This meta-analysis indicates that CA has better overall outcomes than ETA and offers superior clinical benefits in the treatment of incompetent saphenous veins.

Abstract
OBJECTIVE To determine the most effective modality of intervention to treat saphenous vein insufficiency. SUMMARY BACKGROUND DATA Endovenous therapies have instigated a paradigm shift in the management of superficial venous incompetence (SVI). When compared with open surgery, endovenous interventions (foam sclerotherapy (FS), radiofrequency ablation (RFA), endovenous laser ablation (EVLA), mechanochemical ablation (MOCA), and cyanoacrylate glue (CAE) closure) potentially offer reduced morbidity with similar procedural efficacy. METHODS A systematic review and series of network meta-analyses of randomized controlled trials (RCTs) were performed assessing risks of procedural failure (within 6-weeks) and recurrence (6-weeks to 5-years), defined by ultrasound, between the different SVI modalities. Treatment comparisons addressing risks of common adverse events, Venous Clinical Severity Score (VCSS) and pain were also performed. RESULTS A systematic search identified 51 articles, describing 36 RCTs, incorporating 7,576 limbs. Outcome data on ten modalities of intervention were analyzed up to five-year follow-up. CAE resulted in the lowest risk of procedural failure within six-weeks. Foam sclerotherapy had the highest risk of recurrence while high ligation with stripping (HLS) and CHIVA were ranked best to reduce long-term recurrence. No intervention increased risks of venous thromboembolism and there was minimal difference in morbidity between treatments. All interventions improved VCSS (Range -1.02 to -4.95), however RFA demonstrated the greatest improvement, followed by EVLA and HLS between two to five-years. EVLA was associated with the highest risk of pain, while MOCA offered the least. CONCLUSION While CAE offered the lowest risk of initial procedural failure, HLS resulted in lower rates of long-term recurrence without considerably increasing morbidity when compared with other endovenous options.

Abstract
Purpose The aim of this study was to analyze changes in stump length over time in patients with saphenous vein incompetence treated with cyanoacrylate closure (CAC) or radiofrequency ablation (RFA). Methods Materials and We retrospectively analyzed data collected from patients with saphenous vein incompetence who underwent either CAC or RFA at Seoul National University Hospital between November 2015 and December 2018. The stump lengths were measured using duplex ultrasonography (DUS) within 1 month and 6 months after treatment. The Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Questionnaire (AVVQ) score were used to assess clinical outcomes. Results A total of 97 veins (64 great saphenous veins and 33 small saphenous veins) were analyzed. The stump length was not significantly different between the two groups at <1 month (P=0.311). However, the stump length in the CAC group was significantly longer than that in the RFA group at 6 months (P=0.004). At 6 months, the mean change in stump length was 1.41±2.28 cm in the CAC group and 0.51±0.54 cm in the RFA group (P=0.006). The VCSSs and AVVQ scores significantly improved after both procedures but were not significantly different between the two groups. Conclusion DUS at 6 months after treatment showed that the stump length in the CAC group increased more than that in the RFA group. No other factors affected the changes in stump length.

Abstract
Introduction: Endovenous cyanoacrylate glue (CAG) ablation for the treatment of chronic venous
insufficiency (CVI) and varicose veins has shown non-inferior outcomes with an excellent safety profile,
high patient satisfaction rate, and excellent efficacy when compared to the gold standard of endothermal
ablation. A review of the current literature for CAG use in CVI showed that most studies and longer-term
data are from Caucasian-based populations, which are subject to different anatomical venous variations
and socio-economical contexts. This review aimed to gather the current evidence for CAG use in Asian
CVI patients.
Methods: Asian studies for the use of CAG in CVI were included in this review. Successful ablation
rates, quality of life improvement and novel complications such as glue hypersensitivity reactions are
described, along with anatomical descriptions of superficial venous anatomy in study patients. Use of
CAG in Singapore and Asia was addressed.
Results: CAG has been gaining traction as an option for CVI treatment in Asians. In Singapore, it has
been adopted with comparable low complication rates and significant improvement of quality of life
after treatment. As we increase our understanding of the variations in venous anatomy in the Asian
population, new techniques such as retrograde deployment of the device and use of CAG ablation for
venous leg ulcers have been developed.
Conclusion: Further robust evidence in terms of large randomised control trials along with costeffectiveness
studies are needed to determine the true value of CAG ablation in the Asian setting.

Abstract
Background: The current treatment of venous disease is focused on the minimally invasive exclusion of the affected vein. Besides widely used thermal ablation, chemical ablation with cyanoacrylate, reported as safe and highly effective, has been gaining increasing interest. Patients and methods: In the current report, we present data from a two-year observation in 89 patients (61 female/28 male, mean age 44.3 ± 13.5) suffering from venous insufficiency (C2–C4), treated either using short-chain cyanoacrylate, the VenaBlock system (n = 43) or laser thermoablation with ELVeS 1470 (n = 46). The assessment comprised the occurrence of venous disease-related symptoms and the ultrasound examination of the leg venous system. Results: The frequency of recanalization after 2 years from the VenaBlock procedure was significantly higher than after laser treatment (37.2 vs. 8.7%). Apart from recanalization, in some individuals from both groups, the symptoms of recurrence and/or disease progression, including the development of insufficiency in other veins of treated or contralateral legs (9.3 vs. 15.2% and 9.3 vs. 17.4%, respectively), were observed. Unexpectedly, the general prevalence of the disease progression did not differ significantly between the VenaBlock and ELVeS groups (44.2 vs. 34.8%, respectively). Conclusions: Despite the higher recanalization rate of VenaBlock compared to ELVeS, the overall effectiveness of cyanoacrylate and laser thermoablation after two years was similar. Therefore, both methods similarly failed to prevent recurrence and disease progression, which seem to be method-independent.

Abstract
INTRODUCTION The current treatment of venous disease is focused on reflux elimination in main venous trunks, especially in the saphenous vein. However, a high recurrence rate, independent of the method of treatment, suggests that the reason of low effectiveness may be due to a strategy focused on symptoms, without considering their origin. METHOD The aim of study was the comparison of retrospective data from 535 women with venous disease, either after treatment (n = 183) or not treated before (n = 352). The analysis concerned clinical symptoms and the results of the extended diagnostics, including the examination of the lower limb, pelvic and abdominal veins either using duplex-doppler ultrasound as well as venography with computed tomography or magnetic resonance. RESULTS The comparison of selected venous system parameters revealed more advanced disease progression in previously treated patients, compared to non-treated individuals (e.g., ipsi- or bilateral incompetence of sapheno-phemoral junction-29.5% vs. 20.4%, at P < 0.05 and 13.6% vs. 7.7% at P < 0.05, respectively). This difference could be explained by post-treatment alterations in the venous system, an older age and the higher number of pregnancies in the recurrence group. However, both groups did not differ in regards to the symptoms of pelvic venous insufficiency or the frequency of relevant variants/abnormalities in venous system. CONCLUSIONS Based on the aforementioned findings, we postulate the revision of treatment strategy, which should consider abdominal and pelvic veins as the source of reflux in many female subjects.

Abstract
PURPOSE The objective of this study was to evaluate the incidence of, the risk factors for, the nature of the disease, and the management of hypersensitivity reaction (HSR) after cyanoacrylate closure (CAC) of incompetent saphenous veins in patients with chronic venous disease. METHODS Data consisting of all incompetent saphenous veins, including great saphenous veins, anterior accessory saphenous veins, and small saphenous veins, treated with CAC at Siriraj Hospital (Bangkok, Thailand) from January 2017 to December 2018 were retrospectively evaluated. RESULTS A total of 126 saphenous veins, including 106 great saphenous veins (84.1%), 7 anterior accessory saphenous veins (5.6%), and 13 small saphenous veins (10.3%) of 126 limbs from 101 patients were included. A HSR occurred in 16 of 101 patients (15.8%), in 19 of 126 limbs (15.0%), and in 19 of 126 treated saphenous veins (15.0%). HSR-related erythema, itching, swelling, and pain occurred in 100.0%, 95.0%, 68.4%, and 52.6%, of HSR patients, respectively. HSR occurred 1 week after CAC. All HSR symptoms were mild, could be treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and antihistamine, and were resolved within 1 week. The risk factors for HSR were suprafascial saphenous vein with a depth <1 cm from the skin, and saphenous vein diameter of ≥8 mm. CONCLUSIONS A HSR occurred in 15.8% of patients and in 15.0% of limbs after CAC. Risk factors for HSR were a suprafascial saphenous vein located close to the skin and a large saphenous vein. All HSR symptoms were mild in severity, occurred at 1 week after CAC, and were resolved within 1 week after treatment with nonsteroidal anti-inflammatory drugs and antihistamines. To prevent HSR, CAC should be avoided in suprafascial saphenous veins that are located close to the skin, and CAC in saphenous veins with a size of ≥8 mm should be performed with caution.

Abstract
Chronic venous diseases belong to the most frequent diseases. They can be asymptomatic, cause subjective symptoms or lead to objectif alterations, such as edema, cutaneous alterations and venous leg ulcers. This ultimately results in chronic venous insufficiency (CVI). Varicose veins are a progressive degenerative disease of the venous walls in the superficial venous system of the legs, which can decisively impair the quality of life of those affected. The classification of chronic venous diseases is carried out with the CEAP classification according to clinical, etiological, anatomical and pathophysiological criteria. Instruments, such as the venous clinical severity score, are used for assessment of the severity. The treatment of chronic venous diseases targets the improvement of the subjective complaints and objectifiable alterations. In addition, complications, such as phlebitis and formation of ulcers should be avoided. Invasive procedures, compression treatment and pharmaceutical treatment are complementary and a combination of these procedures can be meaningful. General physical measures, such as propping up the legs and frequent walking, are part of the basic measures for every patient with venous diseases. Compression therapy with medical compression stockings is the gold standard in the noninvasive treatment of symptomatic venous diseases, possibly supplemented by anti-inflammatory drugs. A varicose vein should be eliminated whenever possible. Stripping operations and the less invasive endovenous thermal ablation show comparable results for saphenous vein varicosis. Foam sclerotherapy and percutaneous phlebectomy are the methods of choice for elimination of side branch varicosis; however, recurrences of varicose veins are frequent.

Abstract
There are few long-term histological studies of changes that occur after the treatment of chronic venous disease with cyanoacrylate. In the present study, a histological examination was performed in a 71-year-old man 2 years after he was treated with a VenaSeal™ system. After 2 years, most endothelial cells were destroyed; however, most of the media layer was viable. Moreover, we identified multinucleated giant cells distributed throughout the media layer but found no adventitial infiltration.

Abstract
OBJECTIVE To measure patient preferences for attributes associated with thermal ablation and nonthermal, nontumescent varicose vein treatments. METHODS Data were collected from an electronic patient preference survey taken by 70 adult participants (aged 20 years or older) at three Center for Vein Restoration clinics in New Jersey from July 19, 2019, through August 13, 2019. Survey participation was voluntary and anonymous (participation rate of 80.5% [70/87]). Patients were shown 10 consecutive screens that displayed three hypothetical treatment scenarios with different combinations of six attributes of interest and a none option. Choice-based conjoint analysis estimated the relative importance of different aspects of care, trade-offs between these aspects, and total satisfaction that respondents derived from different healthcare procedures. Market simulation analysis compared clusters of attributes mimicking thermal ablation and nonthermal, nontumescent treatments. RESULTS Of the six attributes studied, out-of-pocket (OOP) expenditures were the most important to patients (37.2%), followed by postoperative discomfort (17.1%), risk of adverse events (16.3%), time to return to normal activity (11.0%), number of injections (10.0%), and number of visits (8.4%). Patients were willing to pay the most to avoid postoperative discomfort ($68.9) and risk of adverse events ($65.8). The market simulation analysis found that, regardless of the level of OOP spending, 60% to 80% of respondents favored attribute combinations corresponding with nonthermal, nontumescent procedures over thermal ablation, and that less than 1% of participants would forgo either treatment under no cost sharing. CONCLUSIONS Patients are highly sensitive to OOP costs for minimally invasive varicose vein treatments. Market simulation analysis favored nonthermal, nontumescent procedures over thermal ablation.

Abstract
AbstractThe management of elimination of the pathological reflux in the saphenous vein has been developed recently by introducing the endovenous thermal techniques (EVTA), which have become the first line treatment. However, thermal techniques require tumescent infiltration, what may be the cause of discomfort. Furthermore, the use of EVTA has a potential risk of thermal damage of superficial nerves and requires to wear stocking after the procedure.Non-thermal non-tumescent techniques (NTNT) were proposed as a valid, safe and effective alternative to EVTA with significant clinical improvement, high complete occlusion rate and high posttreatment patient satisfaction. The most common novel NTNT are catheter-directed cyanoacrylate adhesive closure (CAC) and mechanochemical ablation.In the paper an overview of the currently available data regarding the NTNT efficacy and safety are presented.Based on the literature, NTNT has a high efficacy, comparable with the EVTA techniques, with an acceptable risk increase. However further studies with long-term results are needed also with regard to safety aspects.

Abstract
OBJECTIVE Cyanoacrylate closure of refluxing saphenous veins has demonstrated excellent safety and effectiveness results in feasibility and pivotal studies. This article provides the 36-month follow-up results of a prospective, multicenter, nonrandomized cohort study. METHODS A total of 70 patients were enrolled in a prospective, multicenter study conducted at seven centers in four European countries and underwent treatment of a solitary refluxing great saphenous vein with endovenous cyanoacrylate embolization without the use of tumescent anesthesia or postprocedure compression stockings. The primary effectiveness end point was freedom from recanalization (closure rate) of the great saphenous vein at 6 months. Safety was assessed by occurrence of adverse events after the procedure and during the 6-month follow-up period. Quality of life and clinical improvement parameters were measured before and after the procedure and through a 12-month follow-up period. Anatomic success and clinical improvement were assessed through 36 months after the procedure. RESULTS Of 70 treated patients, 64 (91%) were available for the 3-year follow-up. The closure rates by Kaplan-Meier life table methods at 6-, 12-, 24-, and 36-month time points were 91.4%, 90.0%, 88.5%, and 88.5%, respectively. Through 36 months, the improvement in change of the mean venous clinical severity score over time was statistically significant by dropping from 4.3 at baseline to 0.9 at the 36-month follow-up (P < .001). CONCLUSIONS The 3-year follow-up results of the prospective, multicenter eSCOPE study demonstrated the continued anatomic and clinical effectiveness of cyanoacrylate embolization over an extended follow-up period.

Abstract
OBJECTIVE The aim of A Singapore VenaSeal Real-World Post-Market Evaluation Study (ASVS) was to evaluate the performance of cyanoacrylate closure (CAC) for varicose veins in a prospective multiracial Singaporean Asian cohort. We report early clinical and patient satisfaction outcomes at 3 months after intervention. METHODS There were 100 patients (151 legs; 156 truncal veins) who underwent CAC between April and December 2018. Of the 151 legs, 49 (32.5%) were treated for great saphenous vein (GSV) incompetence, 96 (63.6%) for bilateral GSV incompetence, 1 (0.7%) for small saphenous vein (SSV) incompetence, and 5 (3.3%) for combined unilateral GSV and SSV reflux. At baseline, 68 legs (45.0%) had C4 to C6 disease, and 67 legs (44.4%) had concomitant multiple stab avulsions. Patients were reviewed at 2 and 12 weeks by duplex ultrasound to check for venous recanalization (defined as ≥5 cm in length), pain score, revised Venous Clinical Severity Score, EuroQol-5 Dimension questionnaire score, Aberdeen Varicose Vein Questionnaire score, 14-item Chronic Venous Insufficiency Questionnaire (CIVIQ-14) for quality of life measures, and patient satisfaction. Time to return to work and normal activities were also recorded. RESULTS There were 59 female patients, and mean age was 60.1 ± 12.7 years. There was 100% technical success. Patients tolerated the procedure well and reported low periprocedural pain (mean pain score, 2.9 [range, 0-9]). Patient surveys at the 3-month interval showed high satisfaction rates, with 72 of 91 (79.1%) being extremely or very satisfied. By day 10, of 100 patients, 93 (93%) resumed daily activities, whereas 36 (36%) had returned to work. At 2 weeks, GSV and SSV were completely occluded in 150 of 150 (100%) and 6 of 6 (100%) veins, respectively. At 3 months, GSV and SSV occlusion rates were 140 of 141 (99.3%) and 6 of 6 (100%), respectively. Transient superficial phlebitis was reported in 27 of 151 (18 %) legs, which was self-limited. At 3 months, revised Venous Clinical Severity Score improved from 5.00 (range, 1.00-18.00) to 1.00 (0.00-10.00; P < .001); EuroQol-5 Dimension score, from 0.686 (-0.382 to 1.00) to 1.00 (0.12-1.00; P < .001); Aberdeen Varicose Vein Questionnaire score, from 17.14 (1.29-61.15) to 4.83 (0.00-57.12; P < .001); and 14-item Chronic Venous Insufficiency Questionnaire, from 19.64 (1.79-73.21) to 7.14 (0.00-51.79; P < .001). CONCLUSIONS CAC has a high safety profile and is an effective way to block refluxing truncal veins in Asian patients at early follow-up. Patients are highly satisfied and report low postoperative pain. There is significant continued quality of life improvement at 3 months. Early results are encouraging, but we await further prospective long-term follow-up from the study.

Abstract
OBJECTIVE The proprietary cyanoacrylate closure (CAC) system vs radiofrequency ablation (RFA) trial (VenaSeal Sapheon Closure System Pivotal Study [VeClose]) showed that CAC, a nontumescent, nonthermal, nonsclerosant ablation technique, was effective and noninferior to RFA in vein closure with good 36-month outcomes. Conducted under a separate protocol, the aim of this extended follow-up was to assess the long-term safety and effectiveness of CAC and RFA for the treatment of incompetent great saphenous veins (GSV) at 5 years (60 months) of follow-up. METHODS This 60-month extension study was conducted for all patients who completed the randomized VeClose study and who were willing to participate. The pivotal VeClose study included patients with symptomatic moderate to severe varicosities (Clinical, Etiology, Anatomy, and Pathophysiology [CEAP] class C2-C4b) and symptomatic GSV incompetence who were randomly assigned (1:1) to either CAC or RFA. The primary outcome measure of this 60-month extension study was complete closure of the target vein, with planned exploratory analysis of noninferiority. Secondary outcomes included CEAP class; completion of the Venous Clinical Severity Score, EuroQol-Five Dimension survey, and Aberdeen Varicose Vein Questionnaire; patient satisfaction with treatment; adverse events (AEs) related to target GSV; and details of adjunctive procedures. RESULTS A total of 89 patients completed the 60-month visit, which included 47 from the CAC group, 33 from the RFA group, and 9 CAC roll-in patients. No new recanalization events have been observed in the groups between 36 and 60 months of follow-up. At 60 months, Kaplan-Meier estimates for freedom from recanalization in the randomized CAC and RFA groups were 91.4% and 85.2%, respectively, demonstrating noninferiority of CAC compared with RFA. Both groups demonstrated sustained improvements in EuroQol-Five Dimension and quality of life measures through 60 months. Whereas patients assigned to C0 or C1 clinical class were excluded from the original study, more than half of all returning patients (64% [57/89]) were now assigned to C0 or C1, suggesting an improved clinical class from baseline. Furthermore, 41.1% of returning CAC patients and 39.4% of returning RFA patients are presently at least two CEAP clinical classes lower than at baseline. No long-term device- or procedure-related serious AEs occurred in either group between 36- and 60-month follow-up. CONCLUSIONS CAC and RFA were effective in achieving complete target vein closure of the GSV at long-term follow-up, with CAC demonstrating continued noninferiority to RFA. CAC was also associated with sustained improvements in symptoms and quality of life, lower CEAP class, and high level of patient satisfaction without serious AEs between 36 and 60 months.

Abstract
Chronic venous insufficiency is a common and a highly prevalent vascular disorder, that occurs as a result of venous reflux owing to defective venous valves, which in turn causes venous hypertension with significant symptom burden that can interfere with quality of life. Therapeutic strategy involves lowering the venous pressure by lifestyle changes, compression therapy, and conventional catheter-based thermal ablation and novel nonthermal, nontumescent techniques of ablating the affected veins.

Abstract
OBJECTIVE Several randomized controlled trials (RCTs) have compared different interventions for chronic venous insufficiency (CVI) management, but mixed comparison of these interventions is lacking. The aim of this network meta-analysis was to compare VenaSeal closure system (Medtronic, Minneapolis, Minn) with endovenous laser ablation (EVLA), radiofrequency ablation (RFA), mechanochemical ablation, sclerotherapy, and surgery for management of CVI to achieve anatomic success (complete closure of treated vein within 6 months after intervention) as the primary outcome and health-related quality of life (HRQoL; EuroQol-5 Dimension, Aberdeen Varicose Vein Questionnaire), Venous Clinical Severity Score (VCSS), pain scores, and adverse events as secondary outcomes. METHODS A systematic review of journal databases was undertaken, and RCTs between January 1996 and September 2018 comparing different treatment options were included. Risk of bias and quality of publications were assessed using the Cochrane bias tool; Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for study selection and reporting. Twenty RCTs comprising 4570 patients were analyzed. Data for anatomic success, VCSS, HRQoL, pain score, and adverse events were extracted and analyzed using mixed treatment comparison in a network meta-analysis. A Bayesian fixed or random effects model was selected for analysis. Rank probability graphs were generated for various treatments and corresponding ranks obtained to estimate their probability of being best. Relative treatment effects were calculated in terms of log odds ratios for anatomic success and adverse events. Mean difference was calculated for VCSS, HRQoL, and pain score. RESULTS For the primary outcome measure (anatomic success), VenaSeal system had the highest probability of being ranked first (P = .980); RFA was ranked second (P = .365), EVLA third (P = .397), surgery fourth (P = .290), mechanochemical ablation fifth (P = .695), and sclerotherapy sixth (P = .982). For secondary outcome measures, VenaSeal system ranked third for VCSS (P = .332), fifth for EuroQol-5 Dimension (P = .420), and third for Aberdeen Varicose Vein Questionnaire (P = .300). Although, VenaSeal system was slightly inferior to some of the other interventions for HRQoL, the 95% credible interval of log odds ratio indicated insufficient evidence for any concrete conclusion to be drawn. VenaSeal system ranked first in reduction of postoperative pain score from baseline (P = .690) and was lowest in occurrence of adverse events (P = .650). Odds of occurrence of adverse events was 3.3 times in the sclerotherapy arm, 2.7 times in the EVLA arm, 1.6 times with surgery, and 1.1 times with RFA vs VenaSeal system arm. CONCLUSIONS VenaSeal system is a promising therapeutic option for anatomic success at 6 months, with fewer occurrences of adverse events (wound and groin infection, pulmonary embolism) in CVI patients compared with other interventions in this study. Additional economic analysis including cost-effectiveness analysis would provide interesting perspectives on real-world insights to patients, payers, and providers.
