J Vasc Surg Venous Lymphat Disord 2024:101967. [PMID: 39270843 DOI: 10.1016/j.jvsv.2024.101967] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 08/19/2024] [Accepted: 08/28/2024] [Indexed: 09/15/2024]
Abstract
OBJECTIVE The short-term anatomical success rates of mechanochemical ablation (MOCA) using the Clarivein device (Merit Medical, South Jordan, Utah, United States) in the treatment of great saphenous vein (GSV) incompetence are high. However, the anatomical success rates seem to drop over time. The aim of this study was to determine the long-term outcomes of GSV treatment using the Clarivein and to assess whether specific anatomical features better correlate with clinical or QoL related outcomes. METHODS This is a single-center, prospective cohort study in follow-up of a multicenter, randomized controlled trial, using Clarivein with liquid polidocanol for the treatment of GSV incompetence. The primary outcome was anatomical success (AS), defined as compete occlusion or a recanalized segment, irrespective of reflux, of <10 cm in length. In addition, reflux-free anatomical success (RF-AS) was determined and defined as a complete occlusion or a recanalized segment with <10 cm of reflux. Clinical success was assessed using the Venous Clinical Severity Score (VCSS) and QoL was assessed using the Dutch version of the Aberdeen Varicose Vein Questionnaire (DAVVQ) and the 36-Item Short Form Health Survey (SF-36). Subgroup analyses were performed based on whether AS or RF-AS was achieved or not. RESULTS 109 patients (115 limbs) were included. The mean follow-up time was 8.4 ± 0.9 years (range 5.5-10.3 years). AS was seen in 60.5% of limbs and RF-AS was seen in 72.8% of limbs. Compared to baseline, the overall mean VCSS improved from 5.3 ± 2.4 to 4.1 ± 2.4, and the overall median DAVVQ score from 13.1 (7.3-19.4) to 10.5 (4.8-15.8) (p<0.001). Improvement in VCSS was only significant in patients with successful treatment: 5.5 ± 2.4 to 3.7 ± 2.5 (p<.001) if AS was achieved and 5.0 ± 1.7 to 4.5 ± 1.9 (p=.20) if AS was not achieved. The same results were found for DAVVQ scores: 13.5 (8.7-20.6) to 10.3 (3.0-14.5) (p<001) if AS was achieved and 12.9 (8.3-19.3) to 10.8 (6.7-18.2) (p=.35) if AS was not achieved. Regarding the overall SF-36 scores, the domains vitality, mental health and general health worsened significantly. CONCLUSION In over eight-years of follow-up, anatomical success after the treatment of GSV incompetence using the Clarivein device decreased to 60.5%. However, clinical scores and disease-specific QoL still improved significantly compared to baseline. We found no convincing evidence that the absence of reflux correlates better with clinical and quality of life related outcomes compared to recanalization irrespective of reflux.

Abstract
Background: Mechanical occlusion chemically assisted ablation (MOCA) of incompetent saphenous veins has been utilized since its FDA approval in 2008. However, only recently have longer-term three and 5 year clinical follow up data become available. This updated information necessitates a societal update to guide treatment and ensure optimal patient outcomes. Method: The American Vein and Lymphatic Society convened an expert panel to write a Position Statement with explanations and recommendations for the appropriate use of MOCA for patients with venous insufficiency. Result: This Position Statement was produced by the expert panel with recommendations for appropriate use, treatment technique, outcomes review, and potential adverse events. These recommendations were reviewed, edited, and approved by the Guidelines Committee of the Society. Conclusions: MOCA is effective in alleviating symptoms and a safe treatment option for venous insufficiency. It obviates the need for tumescent anesthesia, has less procedural discomfort and lower risk of thermal nerve or skin injury. It may be used in both the below knee distal GSV as well as the SSV. However, it is associated with significantly lower rates of vessel closure and higher recanalization rates compared to both RFA and EVLA and is less cost effective than thermal techniques. It is an available option for those in whom thermal ablation is not suitable.

Abstract
BACKGROUND To describe the treatment of patients with great saphenous vein (GSV) incompetence and varicose veins (VVs), utilizing an Automated Microfoam Preparation System (AMPS, Varixio®, VB Devices, Barcelona, Spain). METHODS Adults between January and June 2021 were included. The AMPS system was used for foam preparation. Sclerotherapy treatment followed international recommendations. The primary endpoint was GSV closure rate after 36 months. RESULTS 164 patients were enrolled. During the 7-day follow-up period, all GSVs showed complete closure, which was maintained at the 1-year mark. No major complications were reported. A cumulative complete GSV recanalization rate of 6.1% and a partial recanalization rate of 26.8% after 36 months were noted. Some patients (9.7%) required additional treatment. A higher BMI was associated with complete recanalization. CONCLUSION The AMPS offers an easy-to-use and standardized procedure, potentially enhancing treatment outcomes if compared with manual preparation. Caution is advised when treating obese patients.

Abstract
BACKGROUND Mechanochemical endovenous ablation (MOCA) was introduced to treat superficial venous insufficiency of the lower leg with less pain and haematoma. Long-term outcome is still lacking. The purpose was to report long-term outcome and to analyse possible predictors for failure. METHODS The study was a retrospective pooled analysis of two prospective cohorts previously reported, but with prolonged long-term outcome up to 5-years follow-up. RESULTS 163 treated legs were analysed. Mean follow-up was 5.4±0.6 years, in which 33 total failures occurred. Four procedures were partially successful. VCSS improved significantly and remained stable after 1 and 2-years, but significantly rose again after 5-years. AVVQ dropped significantly, but increased after 1 year to 4.3 and 6.1 at 5-years follow-up. CONCLUSION MOCA was effective with minimal pain perioperative. However, anatomical success deteriorated after 1-year and showed even less results after 5-years, mainly due to partly recanalization, while clinical results were less affected. There were no clear clinical predictors for failure.

Abstract
BACKGROUND In the last decade, the microwave ablation catheter specifically for treating lower extremity varicose veins has become popular. However, imited data is available on the efficacy, analysis, and evaluation of endovenous microwave ablation (EMWA) in treating SSV insufficiency. Our objective is to evaluated the feasibility, safety, and 1-year outcomes of EMWA and concomitant foam sclerotherapy of primary small saphenous vein (SSV) insufficiency. METHODS Our team carried out a single-center, retrospective analysis of 24 patients treated with EMWAand concomitant foam sclerotherapy for primary SSV insufficiency. All operations were performed using a MWA catheter and polidocanol for the trunk and branches of the SSV, respectively. The SSV occlusion rate was assessed at the 6- and 12-month follow-up examinations using duplex ultrasound. Secondary outcomes included the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) clinical class; Venous Clinical Severity Score (VCSS); Aberdeen Varicose Vein Questionnaire (AVVQ); periprocedural pain; and complications. RESULTS 100% of the cases have been technically successful. At the 6-month follow-up, all treated SSVs were occluded. The 12-month assessment duplex doppler showed anatomical success in patients with 95.8% (95% confidence interval, 0.756-0.994). The CEAP clinical class, VCSS, and the AVVQ had decreased significantly at the 6- and 12-month follow-up, respectively. CONCLUSIONS EMWA and concomitant foam sclerotherapy is a feasible and effective technique for treating SSV insufficiency.

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
OBJECTIVE To compare the outcomes of thermal and mechanochemical endovenous ablative techniques in patients with varicose veins. MATERIAL AND METHODS We searched the PubMed, EMBASE and Cochrane Library databases for studies devoted to mechanochemical and thermal endovenous ablative techniques from inception until July 2021. The primary outcome was anatomical success. Secondary endpoints were intraoperative pain syndrome, complications, modification of disease severity and quality of life. RESULTS This meta-analysis enrolled 10 comparative studies and 1.252 participants after truncal ablations. The follow-up period ranged from 4 weeks to 36 months. With regard to overall anatomical success, 245 out of 267 (91.8%) patients after mechanochemical ablation and 249 out of 266 (93.6%) patients after thermal ablation had favorable results after a month (low-quality evidence; odds ratio [OR] 0.79; 95% CI 0.40-1.55). No statistical heterogeneity was identified (χ2=1.48; df=2; p=0.48; I2=0%). Further analysis identified different incidence of total occlusion after 12 months or later (OR 0.36; 95% CI 0.11-1.21; p=0.05; I2=68%). Mechanochemical ablation resulted less intraoperative pain. Mean difference was -1.3 (95% CI -2.53- -0.07; p=0.00001). MOCA was followed by fewer incidence of nerve injury, hematoma, deep vein thrombosis and phlebitis. There were more cases of skin pigmentation compared to thermal ablation (low-quality evidence, p>0.05). Subsequent assessment of disease severity identified significant between-group difference of means (-0.64 (95% CI -1.82-0.53; p=0.004) and -0.16 (95% CI -0.43-0.11; p=0.005) after 6 and 12 months, respectively). Further assessment of quality of life revealed no between-group differences. These data were characterized by moderate methodological quality. CONCLUSION Mechanochemical ablation is as effective as standard TA within the first postoperative month. However, this approach is associated with lesser anatomical success after 12 months. In most studies, pain syndrome was less severe in case of mechanochemical ablation. These data suggest that mechanochemical ablation is a safe alternative for varicose veins. However, further large-scale trials are required to define the role of MOCA.

Abstract
Background: The mainstream of incompetent saphenous veins treatment has dramatically changed from the first-generation conventional high ligation and stripping surgery to the second-generation endovenous thermal ablation as a minimally invasive technique using laser or radiofrequency. The third-generation treatment of nonthermal non-tumescent techniques is already available, including cyanoacrylate adhesive closure (CAC) and mechanochemical ablation (MOCA).Current Concepts: The non-thermal non-tumescent techniques are developed to overcome the complications of thermal ablation, including nerve injury and vein perforation. The technique also reduces the need for painful tumescent anesthesia and postoperative compression. MOCA employs a dual injury using a single-catheter-based delivery system consisting of a mechanical abrasion with a rotating wire and chemical ablation with a sclerosant. CAC is executed by injecting a glue that produces a polymer with the blood and obliterates the lumen. CAC does not need tumescent anesthesia and postoperative compression. Therefore, patient recovery is fast and satisfaction is excellent. However, the new devices are expensive and not included in the medical insurance in Korea, and long-term effects of the new treatments are unproven; therefore, the cost-effectiveness is unconfirmed.Discussion and Conclusion: MOCA and CAC are newly developed minimal invasive treatments for varicose veins. They are reported to be safe and effective techniques. However, further studies are needed to evaluate the long-term outcomes and cost-effectiveness.

Abstract
BACKGROUND The purpose of the present study was to identify the ideal polidocanol (POL) concentration for mechanochemical ablation (MOCA) of the great saphenous vein (GSV) using the ClariVein system (Merit Medical, South Jordan, Utah). METHODS We performed a multicenter, randomized, controlled, single-blind trial with a follow-up period of 6 months. Patients with symptomatic primary truncal GSV incompetence were randomized to MOCA + 2% POL liquid (2% group) or MOCA + 3% POL liquid (3% group). The primary outcome was technical success (TS), defined as an open part of the treated vein segment of ≤10 cm in length. The secondary outcomes were alternative TS, defined as ≥85% occlusion of the treated vein segment, postoperative pain, venous clinical severity scores, Aberdeen varicose vein questionnaire scores, and short-form 36-item health survey questionnaire scores, and complications. RESULTS From 2012 to 2018, 364 patients (375 limbs) were included, of which, 189 limbs were randomly allocated to the 2% group and 186 to the 3% group. The TS rate at 6 months was 69.8% in the 2% group vs 78.0% in the 3% group (P = .027). A higher overall TS rate was seen in GSVs of ≤5.9 mm compared with GSVs >5.9 mm (84.3% vs 59.5%, respectively; P < .001). The alternative TS rate at 6 months was 61.4% in the 2% group and 67.7% in the 3% group (P = .028). The venous clinical severity scores, Aberdeen varicose vein questionnaire scores, and most short-form 36-item health survey questionnaire domains had improved in both groups (P < .002). Postprocedural pain was low. Two pulmonary embolisms and two deep vein thromboses were seen. Superficial venous thrombosis had occurred more often in the 3% group (18 vs 8 in the 2% group; P = .033). CONCLUSIONS The results from the present study showed a higher success rate for MOCA with 3% POL liquid than for MOCA with 2% POL liquid at 6 months of follow-up. However, the difference in quality of life was not significant. Long-term follow-up studies are required to investigate whether these results will be sustained in the future.

Abstract
PURPOSE OF REVIEW Chronic venous insufficiency is found to some extent in a large proportion of the world's population, especially in the elderly and obese. Despite its prevalence, little research has been pursued into this pathology when compared to similarly common conditions. Pain is often the presenting symptom of chronic venous insufficiency and has significant deleterious effects on quality of life. This manuscript will describe the development of pain in chronic venous insufficiency, and will also review both traditional methods of pain management and novel advances in both medical and surgical therapy for this disease. RECENT FINDINGS Pain in chronic venous insufficiency is a common complication which remains poorly correlated in recent studies with the clinically observable extent of disease. Although lifestyle modification remains the foundation of treatment for pain associated with chronic venous sufficiency, compression devices and various pharmacologic agents have emerged as safe and effective treatments for pain in these patients. In patients for whom these measures are insufficient, recently developed minimally invasive vascular surgical techniques have been shown to reduce postsurgical complications and recovery time, although additional research is necessary to characterize long-term outcomes of these procedures. This review discusses the latest findings concerning the pathophysiology of pain in chronic venous insufficiency, conservative and medical management, and surgical strategies for pain relief, including minimally invasive treatment strategies.

Abstract
BACKGROUND The endovascular technique of mechanochemical ablation (MOCA) has become popular in treating patients with saphenous reflux. We reported the histopathological findings in human ex-vivo incompetent great saphenous veins following treatment with saline, polidocanol, mechanical ablation and MOCA using ClariVein device. METHODS Twenty-four vein GSV specimens were obtained via traditional surgery and treated with four methods: Group A: 0.9% normal saline (NS); Group B: 3% polidocanol; Group C: mechanical ablation + 0.9% NS; Group D: mechanical ablation + 3% polidocanol (MOCA). Hematoxylin and eosin (HE), Masson's trichrome and immunohistochemical staining were performed on each specimen and integrated optical densities were measured with vWF and a-SMA stains and statistically evaluated. vWF staining was used to assess endothelial damage and a a-SMA staining was used to assess media injury. RESULTS HE and Masson's trichrome staining of Groups C and D revealed severe damage to the endothelium and media compared to Groups A and B. The statistical result of vWF staining showed the damage of endothelium was significantly increased by Group D compared to Groups A, B and C. The statistical result of a-SMA staining showed the damage of media was significantly increased by Groups C and D compared to Groups A and B. CONCLUSIONS The mechanism of MOCA was caused by both endothelium damage and media tearing. The damage of endothelium was significantly increased by MOCA when compared with mechanical ablation alone.

Abstract
This study aimed to review the pathophysiology of varicose veins and chronic venous insufficiency and the recent surgical treatment trend. Varicose veins are tortuous, twisted, or lengthened veins in the lower extremities. It is part of the spectrum of chronic venous disease. Primary pathogenesis is increased chronic venous hypertension caused by valvular insufficiency, venous outflow obstruction, and calf muscle pump failure. Some patients complain of no symptoms, except report cosmetic concerns. If the varicose vein progresses to chronic venous insufficiency, it may cause edema of the lower limb. The skin lesion can present as hyperpigmentation of the median part of the ankle, congestive dermatitis, and even a skin ulcer. The varicose vein can be diagnosed easily by visual inspection after identifying the skin lesions. For non-surgical treatment, elastic stocking, Unna boots, and pneumatic compression devices are recommended to reduce venous pressure. High ligation with stripping has been the standard treatment for varicose veins to achieve symptom relief and improve cosmetic effects. Endovenous laser ablation, radiofrequency ablation, mechanochemical ablation, and the VenaSeal closure system have been introduced as surgical treatment methods. Recently, endovenous thermal/non-thermal ablations are recommended for treatment because both are less invasive techniques. The appropriate therapy should be selected after considering the patients’ symptoms and signs, anatomical structure, and economic burden of the treatment.

Abstract
PURPOSE To evaluate feasibility, safety, and results of endovenous mechanochemical ablation (MOCA) for treatment of persistent embryonic and dysplastic veins in pediatric patients with Klippel-Trénaunay syndrome (KTS). MATERIALS AND METHODS Thirteen MOCA procedures were performed in 11 patients (age range, 4-16 years) with KTS and symptomatic persistent embryonic or dysplastic veins during a 24-month period. All patients were evaluated with color Doppler (CD) ultrasound (US), contrast-enhanced MR imaging, and venography to assess the anatomy of the target vessels and patency of the deep venous system. All procedures were performed under general anesthesia with a ClariVein catheter and liquid sodium tetradecyl sulfate as the sclerosing agent. US and fluoroscopic guidance were used in all cases. Technical success rate, primary occlusion rate, adverse effects, and recanalization rates were evaluated. Clinical and radiological (CD US) controls were performed 1 day, 7 days, 1 month, and 6 months after the procedure and once a year thereafter, with a mean follow-up of 16 months (range, 6-25 months). RESULTS Technical success and primary occlusion were achieved in all patients with no adverse events. During the follow-up period, CD US demonstrated partial recanalization and symptom recurrence in 2 patients (18%), 14 and 18 months after the initial procedure. These 2 patients had a second ablation procedure with no recanalization or symptom recurrence during the subsequent follow-up period. CONCLUSIONS MOCA is feasible and appears to be a safe and effective technique for treatment of varicose veins in pediatric patients with KTS.

Abstract
Although ultrasound-guided interventional procedures have resulted in great advances in many fields of medicine, this approach has revolutionized endovascular procedures. This paper aims to review the basic principles to develop a strategy to follow in ultrasound-guided treatments of varices in the lower limbs, as well as to provide a brief overview of the main endovenous techniques available nowadays. We divide these techniques into those that use catheters to occlude straight saphenous axes (thermal / non-thermal ablation) and other options, such as foam sclerotherapy, which can be used in all types of varices, even in those originating in the pelvis.

Abstract
Presented herein is a clinical case report regarding successful treatment of a trophic ulcer of the right tibia by means of endovenous mechanochemical ablation of the great saphenous vein using the FlebogrifTM device. According to ultrasonography findings, the patient was found to have insufficiency of the saphenofemoral junction, axial truncal reflux, and the absence of incompetent perforator veins in the area of trophic disorders. Taking into account the clinical and ultrasound picture of the disease, the decision was made on the feasibility of performing crossectomy and retrograde mechanochemical ablation of the great saphenous vein. The chosen modality of the invasive intervention did not require tumescent anesthesia, allowed a catheter to be placed under the ulcer bed and, unlike thermal methods, excluded the risk of damage to the subcutaneous nerves and soft tissues. The operation made it possible to eliminate pathological truncal reflux along the entire length, which contributed to rapid healing of the trophic ulcer, relief of varicose disease symptoms, and significant improvement of the patient's quality of life. This clinical case report indicates the possibility of application of retrograde endovenous mechanochemical ablation in a patient with varicose disease, axial reflux and open venous ulcer (C6) and warrants further research in this direction.

Abstract
OBJECTIVE the aim of this study was to assess the results of mechanochemical endovenous ablation either in the primary or recurrent saphenous vein insufficiency, including only patients with veno-venous shunt type III. METHODS retrospective analysis of a prospective study of patients with symptomatic chronic venous insufficiency who underwent ClariVein® technique. A total of 134 saphenous veins were included between August 2017 and August 2018. Follow-up was performed by Duplex ultrasound at 1, 6 and 12 months. Primary endpoints were technical and anatomical success. Secondary endpoints were the need for further treatment of varicose collateral veins by sclerotherapy, outcomes regarding recurrent insufficiency and clinical success. RESULTS A total of 111 great saphenous veins and 23 small saphenous veins were treated with a technical success of 95.6%. The overall anatomical success rates at 1, 6 and 12 month were 96.2%, 88.8% and 84.4%, respectively, without differences between primary and recurrent insufficiency. Deferred sclerotherapy over varicose collaterals was carried out in 28% of the patients with anatomical success. Clinical improvement was achieved in 87.3%. CONCLUSIONS MOCA technique has proven to be an effective technique, although additional treatment over varicose collaterals could be necessary in up to one-third. Atrophy of the saphenous vein and the lack of persistent varicose collateral veins during follow-up seem to be indicators of successful therapy.

Abstract
OBJECTIVE Mechanochemical ablation (MOCA) is a nonthermal nontumescent method of treating saphenous vein insufficiency. The feasibility and short-term results of MOCA are good, but its long-term results are unknown. A randomized study was performed to compare MOCA with endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) in the setting of unilateral great saphenous vein (GSV) insufficiency. METHODS Venous outpatient clinic patients with varicose veins (CEAP class C2-C4) caused by GSV insufficiency were invited to participate in the study; in total, 132 patients met the inclusion criteria and were willing to participate. Patients were randomized to treatment (2:1:1 for MOCA, EVLA, and RFA, respectively). The state of the GSV with duplex Doppler ultrasound examination and the disease-specific quality of life were assessed at 1 month, 1 year, and 3 years after the treatment. RESULTS Some patients declined to continue in the study after randomization; in total, 117 patients underwent treatment. At 3 years, the occlusion rate was significantly lower with MOCA than with either EVLA or RFA (82% vs 100%; P = .005). Quality of life was similar between the groups. In the MOCA group, GSVs that were larger than 7 mm in diameter preoperatively were more likely to recanalize during the follow-up period. The partial recanalizations of proximal GSV observed at 1 year progressed during the follow-up. CONCLUSIONS MOCA is a feasible treatment option in an outpatient setting, but its technical success rates are inferior compared with endovenous thermal ablation. Its use in large-caliber veins should be considered carefully.

Abstract
BACKGROUND Initial phase III clinical studies with polidocanol endovenous microfoam (PEM) demonstrated its safety and efficacy in the treatment of superficial venous reflux. In those studies, the primary outcome requirement was to assess the improvement in symptoms related to superficial venous disease. The goal of the present study was to evaluate the efficacy of PEM technology in routine clinical practice-specifically, the closure rates after treatment. METHODS We performed an observational study during which data were prospectively collected from 2 vein centers using an electronic database. Patients with CEAP (clinical, etiologic, anatomic, pathophysiologic) class ≥2 and symptomatic superficial axial reflux (great saphenous vein, anterior accessory saphenous vein, and small saphenous vein) were included and followed up prospectively. PEM was used to treat the saphenous vein and varicosities. The CEAP classification was used to classify chronic venous disease, and the venous clinical severity score (VCSS) was applied to measure the disease severity. Pain and discomfort were assessed using a visual analog scale, and the residual veins were assessed by physical examination. RESULTS PEM was used to treat superficial reflux in 60 patients. The CEAP classification was C2 for 32 patients, C3 for 14, C4 for 10, and C5 for 4 patients. The average pretreatment VCSS was 7.3. The saphenous vein diameter was 6.5 mm, and the average length was 31 cm. The average volume of PEM used to treat the saphenous veins was 9.3 mL. The closure rate at 3 and 6 months was 93% (54 of 58) and 93% (51 of 55), respectively. The VCSS had improved from 7.3 to 1.4. Complications included 1 case of deep vein thrombosis (1.7%), 5 patients (8.3%) with thrombophlebitis, and 4 patients (6.6%) with skin pigmentation. CONCLUSIONS PEM is safe and effective for the treatment of saphenous reflux and varicosities. The early closure rates using PEM were maintained at 6 months and are comparable to the results reported with nonthermal, nontumescent technologies and thermal tumescent technologies.

Abstract
OBJECTIVE Endothermal techniques have proved to be effective for treatment of incompetent truncal veins. The tumescentless mechanochemical ablation (MOCA) technique has become an alternative treatment modality, but its outcome with regard to endothermal techniques is still unclear. METHODS A multicenter prospective randomized controlled trial was designed comparing MOCA with radiofrequency ablation (RFA) to treat great saphenous vein incompetence with the hypothesis that MOCA is associated with less postprocedural pain and a comparable anatomic and clinical success rate at 1-year follow-up. Disease-specific quality of life and general health-related quality of life (HRQoL) were measured using questionnaires. Inclusion was terminated prematurely because reimbursement was suspended. RESULTS A total of 213 patients (46.3% of intended number of patients) were randomized, of whom 209 were treated (105 in the MOCA group and 104 in the RFA group). Overall median pain scores during the first 14 days were lower after MOCA (0.2 vs 0.5 after RFA; P = .010), although the absolute difference was small. At 30 days, similar complication numbers (MOCA, n = 62; RFA, n = 63) and HRQoL scores (Aberdeen Varicose Vein Questionnaire: MOCA, 8.9; RFA, 7.6; P = .233) were observed. Hyperpigmentation was reported in seven patients in the MOCA group and two patients in the RFA group (P = .038). In the MOCA group, there were four complete failures (3.8%) compared with none in the RFA group (P = .045), although in one patient at 1 year, the vein showed occlusion. Median 30-day Venous Clinical Severity Score (VCSS) was significantly lower at 30 days after MOCA (1.0 vs 2.0 in the RFA group; P = .001), whereas VCSS was comparable at baseline (MOCA, 4.0; RFA, 5.0; P = .155). The 1- and 2-year anatomic success rate was lower after MOCA (83.5% and 80.0%) compared with RFA (94.2% and 88.3%; P = .025 and .066), mainly driven by partial recanalizations. After 2 years of follow-up, no differences were observed in the number of complete failures. Similar clinical success rates at 1 year (MOCA, 88.7%; RFA, 93.2%; P = .315) and 2 years (MOCA, 93.0%; RFA, 90.4%; P = .699) and no differences in HRQoL scores on the Aberdeen Varicose Vein Questionnaire at 1 year (MOCA, 7.5; RFA, 7.0; P = .753) and 2 years (MOCA, 5.0%; RFA, 4.8%; P = .573) were observed. There were two cardiac serious adverse events, a ventricular fibrillation in the MOCA group (1 year) and an unstable angina in the RFA group (2 years). One deep venous thrombosis occurred in the RFA group on 1-year duplex ultrasound, without clinical sequelae. CONCLUSIONS Unilateral treatment with MOCA in the short term resulted in less postoperative pain but more hyperpigmentation compared with RFA and a faster improvement in VCSS. More anatomic failures were reported after MOCA, mostly driven by partial recanalizations, but both techniques were associated with similar clinical outcomes at 1 year and 2 years.

Abstract
PURPOSE A previous meta-analysis has conducted nonrandomized trials for mechanochemical ablation (MOCA). Since medium-term follow-up data from randomized clinical trials (RCTs) are becoming available, we chose to perform a meta-analysis of RCTs to assess the efficacy and safety of MOCA for saphenous vein insufficiency. METHODS A systematic search of all RCTs comparing the anatomical success of MOCA for saphenous vein insufficiency to thermal ablation was performed using the PubMed and Cochrane Library databases. We employed the Mantel-Haenszel random-effects meta-analysis of outcomes using RevMan 5.3. RESULTS Four studies (615 patients) were included in this meta-analysis. The MOCA group had 93.4% and 84.5%, whereas the thermal ablation group had 95.8% and 94.8% of anatomical success rate at 1 month (short-term) and a period of more than 6 months but less than 1-year follow-up (mid-term), respectively. According to intention-to-treat analysis, there were similar anatomical successes in MOCA and thermal ablation groups at the short-term follow-up (low-quality evidence; relative risk (RR) = 0.98 (95% CI, 0.94-1.03); P = 0.44; I 2 = 53%). The estimated effect of MOCA on anatomical success showed a statistically significant reduction at the mid-term follow-up (moderate-quality evidence; RR = 0.89 (95% CI, 0.84-0.95); P = 0.0002; I 2 = 0%). MOCA had fewer incidence of nerve injury, deep vein thrombosis, and skin burns compared to the thermal ablation procedure (low-quality evidence; RR = 0.33 (95% CI, 0.09-1.28); P = 0.11; I 2 = 0%). CONCLUSION MOCA offered fewer major complications but lesser anatomical success at the period of more than 6 months but less than 1-year follow-up than thermal ablation. Trial Registration. This trial is registered with UMIN Clinical Trial Registry (UMIN ID 000036727).

Abstract
Guidelines are fundamental in addressing everyday clinical indications and in reporting the current evidence-based data of related scientific investigations. At the same time, a spatial and temporal issue can limit their value. Indeed, variability in the recommendations can be found both among the same nation different scientific societies and among different nations/continents. On the other side, Garcia already published in 2014 data showing how, after three years in average, one out of five recommendations gets outdated (Martinez Garcia LM, Sanabria AJ, Garcia Alvarez E, et al. The validity of recommendations from clinical guidelines: a survival analysis. CMAJ 2014;186(16):1211–1219). The present document reports a narrative literature revision on the major international recommendations in lower limb venous and lymphatic disease management, focusing on the different countries’ guidelines, trends and controversies from all the continents, while identifying new evidence-based data potentially influencing future guidelines. World renowned experts’ opinions are also provided. The document has been written following the recorded round tables scientific discussions held at the vWINter international meeting (22–26 January 2019; Cortina d’Ampezzo, Italy) and the pre- and post-meeting literature search performed by the leading experts.

Abstract
Objective The aim of the study is to report long-term results after mechano-chemical ablation for the treatment of great saphenous vein incompetence. Methods Mechano-chemical ablation was performed using the ClariVein device with polidocanol as the sclerosant. Clinical-Etiologic-Anatomic-Pathophysiologic (CEAP) classification, Venous-Clinical-Severity-Score (VCSS), anatomical-success, RAND-SF36 and the Aberdeen-Varicose-Vein-Questionnaire (AVVQ) were obtained by clinical examination, questionnaires and duplex ultrasonography through five years’ follow-up (Clinicaltrials.gov, NCT01459263). Results Ninety-four patients (113 great saphenous veins) were included in the study. Five-year follow-up data were available for 75 limbs (66.4%). Freedom from anatomical failure was 78.7% (N = 45) with 64.6% (N = 42) having an improvement in the VCSS ≥1. A total of five reinterventions were performed through five years with a median time to reintervention of 38 months. The VCSS at five years was 2 (IQR 1; 4) and was still significantly improved compared to baseline (p < 0.001). A deterioration of the VCSS was observed in 21.5%. Conclusion Through five-year follow-up, there are a significant number of anatomical and clinical failures in this series, mainly driven by partial recanalizations.

Abstract
Background The purpose of the guideline was to achieve consensus in the care and treatment of patients with chronic venous disease, based on current evidence. Method A systematic literature search was performed in PubMed, Embase, Cinahl, and the Cochrane library up until 1 February 2019. Additional relevant literature were added through checking of references. Level of evidence was graded through the GRADE scale and recommendations were concluded. Results For the treatment of great and small saphenous vein reflux, endovenous ablation with laser or radiofrequency was recommended in preference to surgery or foam sclerotherapy. If tributaries are to be treated it should be done in the same procedure. Treatment with mecanicochemical ablation and glue can be used but we still need long term follow up results. Conclusion For the treatment of truncal varicosities, endovenous ablation with laser or radiofrequency combined with phlebectomies is recommended before surgery or foam.

Abstract
OBJECTIVES This study assessed the effectiveness and patient experience of ClariVein for varicose veins and chronic venous insufficiency (CVI) in a multi-ethnic Asian population from Singapore. METHODS A total of 121 patients underwent mechano-chemical ablation. Patients were reviewed at an interval of one week, and at 3, 6 and 12 months post procedure and underwent Duplex ultrasound with patient satisfaction assessment. RESULTS At three months of follow-up, the great saphenous vein and short saphenous vein occlusion rates were 90.8% and 96.0%, respectively. At six months of follow-up, the GSV and short saphenous vein occlusion rates were 86.9% and 90.9%, respectively. At one year, great saphenous vein and short saphenous vein occlusion rates were 84.8% and 94.3%, respectively. CONCLUSIONS Early results are similar to what is described so far in the mechano-chemical ablation literature but recurrences are more than expected at one year. This is disappointing but is tempered by the fact that the majority of patients were asymptomatic and required no reintervention.

Abstract
Finally Daily Routine: Endovenous Outpatient Treatment of Varicose Veins Abstract. During the last 20 years endovenous treatment options have replaced surgery of varicose veins in many countries or stand for an equally effective alternative treatment option. Endothermal ablation of refluxing saphenous veins by Laser or radiofrequency means outpatient treatment under local anesthesia and immediate return to routine daily activity. Prospectively randomized trials with follow-up intervals of 5 years show equal efficacy and a similar side effect profile of endothermal saphenous vein ablation compared to surgery, therefore, various guidelines of international scientific societies either recommend endothermal treatments over surgery or at least as an equally ranked treatment alternative. Currently, non-thermal-non tumescent treatment options like cyanoacrylate glue or mechanochemical ablation open a new chapter for the treatment of refluxing saphenous veins. Early results are promising, however, prospectively randomized trails comparing established treatment options are currently rare.
