Abstract
Endovenous thermal ablation is a first-line treatment for symptomatic varicose veins due to truncal vein reflux. Ablation of an incompetent great saphenous vein is usually performed from distally, with the vein access at the lowest point of reflux, or just below the knee. Occasionally there are patients in whom the great saphenous vein is difficult to access distally for reasons such as small vein diameter, scar tissue, vasospasm, difficult anatomy or multiple attempts with haematoma formation. In such cases, we access the great saphenous vein in a retrograde fashion by percutaneous cannulation of the superficial inferior epigastric vein, passing the catheter into the great saphenous vein just distal to the saphenofemoral junction and then down the vein to the required distal position. Ablation can then be performed, stopping the ablation in the great saphenous vein just distal to the junction of superficial inferior epigastric vein and great saphenous vein. We present a patient to illustrate our technique.

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 We aimed to compare mechanochemical ablation (MOCA) and thermal ablation (radiofrequency ablation and endovenous laser therapy) for venous ulcer healing in patients with clinical class 6 chronic venous insufficiency. METHODS Electronic medical records were reviewed of patients with venous ulcers who underwent truncal or perforator ablation between February 2012 and November 2015. These records contained history of venous disease and ulcer history, procedures, complications, follow-up, method of wound care, and current status of the ulcer. The patients were grouped according to the method of ablation for comparison. RESULTS In 66 patients, 82 venous segments were treated, 29 with thermal methods and 53 with MOCA; 16% of patients had prior venous intervention. Before ablation, three patients in the thermal group had a history of deep venous thrombosis compared with seven in the MOCA group. On average, patients treated with MOCA were older (thermal ablation, 57.2 years; MOCA, 67.9 years; P = .0003). Ulcer duration before intervention ranged from 9.2 months for thermal ablation to 11.2 months for MOCA (P = NS). In total, 74% of patients treated with MOCA healed their ulcers compared with 35% of those treated with thermal ablation (P = .01). A healed ulcer was defined as elimination of ulcer depth and superficial skin coverage. The mean time to heal was 4.4 months in the thermal ablation group compared with 2.3 months with MOCA (P = .01). The mean length of follow-up was 12.8 months after thermal ablation and 7.9 months after MOCA (P = .02). Both age (P = .03) and treatment modality (P = .03) independently had an impact on ulcer healing on multiple logistic regression analysis. All but two patients were treated with an Unna boot after venous ablation. Complications included readmission of two patients with nonaccess-related infections, one nonocclusive deep venous thrombosis, and one late death unrelated to the procedure second to pneumonia in the setting of advanced colon cancer. There were three recurrent ulcers at 1 week, 2 months, and 7 months after MOCA that rehealed with Unna boot therapy and continued compression. CONCLUSIONS MOCA is safe and effective in treating chronic venous ulcers and appears to provide comparable results to methods that rely on thermal ablation. Younger age and use of MOCA favored wound healing. MOCA was an independent predictor of ulcer healing. Randomized studies are necessary to further support our findings.

J Vasc Surg Venous Lymphat Disord 2020; 8:1041-1048. [PMID: 32205130 DOI: 10.1016/j.jvsv.2020.01.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Accepted: 01/17/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVE Patients with venous leg ulcers (VLUs) represent the worse spectrum of chronic venous insufficiency (CVI). The Early Venous Reflux Ablation (EVRA) landmark trial published in 2018 demonstrated that early endovenous intervention results in faster healing of VLUs. We describe our post-EVRA experience using endovenous cyanoacrylate glue ablation (ECGA) to treat superficial venous reflux on an early basis and assess its efficacy and safety in the setting of VLUs. METHODS There were 37 patients (39 legs, 43 truncal veins) with 43 discrete venous ulcers who underwent ECGA for CVI symptoms and VLUs. They received compression therapy and regular dressings for the VLUs postoperatively and were reviewed at 1 week, 3 months, 6 months, and 12 months after the procedure. Postoperative healing time for VLUs and complications were recorded along with the patient's satisfaction and postprocedure pain scores. RESULTS The venous ulcers were all <30 cm2 before ECGA. The mean time for VLU healing from operation was 73.6 ± 21.9 days, and the primary occlusion rate of the CVI at both 1 week and 3 months was 100%. No major adverse events were observed except for one case of deep venous thrombosis. There was significant improvement in the revised Venous Clinical Severity Score postoperatively from 11 ± 1.63 (baseline) to 5.6 ± 1.37 (P < .001) at 3-month follow-up (on a scale of 0 to 27, with the severity of symptoms at a maximal 27). The visual analog scale scores for pain were low postoperatively, decreasing from a preoperative score of 6.84 ± 1.42 to 2.72 ± 1.59 (P < .001) at the 3-month follow-up (on a scale of 1-10, with 10 being the most severe pain). The median time to return to normal activities was 7 days (interquartile range, 5-7 days). CONCLUSIONS ECGA together with compression therapy for VLUs is both safe and effective in this population of Asian patients. ECGA for patients with VLUs has excellent patient acceptability, minimal morbidity, and low recanalization rates at 12 months. Larger extensive studies and longer follow-up periods are required to validate the preliminary outcomes of this paper, and if it is proven to significantly improve ulcer healing rates, this will change the way we approach chronic venous ulceration.

Retrograde technique for great saphenous vein ablation using the VenaSeal™ closure system – Ideal approach for deep seated or small below the knee refluxing truncal veins.

Abstract
Objectives The VenaSeal™ closure system (Medtronic, Galway, Ireland) is a novel non-thermal, non-tumescent ablative device that induces endovenous closure by inducing fibrosis of the truncal superficial vein. The conventional IFU antegrade technique is straightforward except when the great saphenous vein is small at the planned access site below the knee, deep, or steeply traverses the fascia making passage of the introducer wire to the groin difficult. We describe our technique for retrograde great saphenous vein puncture, which mitigated these access problems and assessed the effectiveness and outcomes. Methods Fourteen patients (14 legs; 14 great saphenous vein) underwent VenaSeal™ ablation via a retrograde puncture, all for great saphenous vein incompetence; 10/14 (71.4%) had C4–C5 disease. Retrograde puncture introduces the VenaSeal™ catheter in a cranial-caudal manner, with the designated puncture site at the most proximal point of the great saphenous vein reflux. Patients were reviewed at 1 week, 3, 6 and 12-months post-procedure. Post-operative outcomes and complications were recorded, along with patient satisfaction. Results The most common reason for a retrograde puncture approach was the small great saphenous vein calibre below the knee, in 9/14 (64.3%) patients. There was 100% technical success, with no major complications from the procedure; 11/14 (78.6%) patients tolerated the procedure under local anaesthesia without any sedation. There was 100% Duplex-occlusion rate at 1 week, 3, 6 and 12-months post-procedure. Conclusion The retrograde puncture technique for the VenaSeal™ Closure system is safe and effective in ablating the great saphenous vein in patients who are not amendable to the conventional antegrade puncture approach. Patients tolerated this procedure without additional mean operative time and minimal complications. More extensive studies with longer follow-up periods are required to validate the long-term outcomes of this technique.

Abstract
Objectives The aim of this study is to investigate whether there are differences between predominantly Caucasians and Asians from two disparate cohorts around the globe, with regard to their pre-operative venous reflux patterns and truncal vein characteristics, which could potentially help clinicians tailor venous treatment for chronic venous insufficiency on a more individualised basis in different parts of the world. Methods A total of 200 lower limb chronic venous insufficiency duplex studies (127 Singaporean (predominantly Asian) patients) and 200 lower limb chronic venous insufficiency duplex scans (137 Americans predominantly Caucasians) were analysed and compared for differences in venous anatomy and reflux characteristics. Results Asian patients from Singapore presented with higher CEAP scores compared to the predominantly Caucasian cohort from the US (30% CEAP 4a or greater vs. 17.5%; p < 0.01). Singaporeans had more great saphenous vein reflux starting at the sapheno-femoral junction (86% vs. 73%; p < 0.01) and ending at the ankle (93% vs. 46%; p < 0.01). Vein diameters were generally larger in the US cohort of patients (median 5.7 mm vs. 2.9 mm; p < 0.01). Conclusions The predominantly Asian cohort from Singapore had smaller diameter truncal veins, longer segments of truncal vein reflux and present later with more advanced chronic venous insufficiency compared to their American counterparts. This information could help tailor endovenous ablation on a more individualised basis in the future.

Abstract
Objectives The aim of this prospective single-centre study is to assess the effectiveness and patient experience of the VenaSeal™ Closure System, a novel non-thermal, non-tumescent catheter technique, which uses cyanoacrylate glue to occlude the refluxing truncal superficial veins to treat varicose veins and chronic venous insufficiency, in a multi-ethnic Asian population from Singapore. Methods Seventy-seven patients (93 legs; 103 procedures) underwent VenaSeal™ Closure System ablation. Forty-nine (63.6%) for great saphenous vein incompetence, 16 (20.8%) bilateral great saphenous vein, 2 (2.6%) small saphenous vein and 10 (13.0%) combined unilateral great saphenous vein and small saphenous vein/anterior thigh vein reflux. In addition, 65/93 legs (69.9%) had C4–C6 disease. Patients were reviewed at 2 weeks, 3, 6 and 12 months post-procedure. Results There was 100% technical success. 28/77 (36.4%) underwent concomitant phlebectomies. All procedures were well tolerated with a mean post-operative pain score of 3.0 (range: 0–5). After three months, median patient satisfaction was 9.0 (interquartile range: 7.0–10.0). At two-week follow-up, the great saphenous vein was completely occluded in 88/88 (100%) veins and small saphenous vein completely closed in 11/11 (100%) veins. At three-month follow-up, the great saphenous vein was occluded in 51/53 (96.2%) veins and small saphenous vein completely closed in 5/5 (100%) veins. At six-month follow-up, the great saphenous vein was completely occluded in 42/45 (93.3%) veins and small saphenous vein completely closed in 5/7 (71.4%) veins. At one year, great saphenous vein and small saphenous vein occlusion rates were 54/59 (91.5%) and 5/8 (62.5%), respectively. There was one deep vein thrombosis. Transient superficial phlebitis was reported in 10/93 (10.8%) legs, which were all self-limiting. There were 9/103 (8.7%) anatomical recurrences, but no patients required re-intervention as they were asymptomatic. Conclusions Cyanoacrylate glue is a safe and efficacious modality to ablate refluxing saphenous veins in Asian patients in the short term. There is a high satisfaction rate and peri-procedural pain is low. Early results are promising but further evaluation and longer term follow-up are required.

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
RESUMO A termoablação endovascular das veias safenas insuficientes com laser é descrita como uma técnica menos invasiva, com resultados semelhantes à cirurgia convencional, porém, com efeitos adversos menos frequentes. A técnica de escleroterapia com espuma de polidocanol ecoguiada vem sendo empregada com a mesma finalidade. A combinação de técnicas pode representar uma alternativa para pacientes mais graves, como os portadores de úlcera varicosa. Um equipamento de laser (denominado VELAS) foi desenvolvido no Centro de Pesquisas em Ótica e Fotônica da USP-São Carlos em convênio com a FMB-UNESP para termoablação endoluminal da veia safena insuficiente. Neste estudo apresentamos os resultados preliminares do uso do aparelho de laser VELAS (diodo MMO 980nm) na termoablação endovascular de veias safenas insuficientes, em portadores de úlcera venosa crônica, associado à complementação com espuma de polidocanol para o tratamento de varicosidades, após uma semana. Os desfechos analisados foram o tempo de cicatrização da úlcera venosa, oclusão das veias tratadas e eventos adversos relacionados aos tratamentos. Foram incluídos 12 pacientes portadores de insuficiência de veia safena e úlcera venosa crônica que aceitaram participar do projeto. Todos foram tratados em regime ambulatorial, com anestesia local e termoablação da veia safena insuficiente (VELAS). Após uma semana da cirurgia, as varicosidades foram esclerosadas com polidocanol espuma (técnica de Tessari). O equipamento laser VELAS nacional apresentou fácil manuseio, oclusão venosa total em 83,3% dos pacientes (em sete dias) e a associação das técnicas foi responsável por uma taxa de cicatrização de feridas de 83,3%, sem ocorrência de eventos adversos.

Abstract
Background Several studies have shown comparable early efficacy of mechanochemical ablation to endothermal techniques. The goal of this report was to show if early efficacy is maintained at 24 months. Methods This was a two-year analysis on the efficacy of mechanochemical ablation in patients with symptomatic C2 or more advanced chronic venous disease. Patients with reflux in the great saphenous vein involving the sapheno-femoral junction and no previous venous interventions were included. Demographic information, clinical, and procedural data were collected. The occlusion rate of treated veins was assessed with duplex ultrasound. Patient clinical improvement was assessed by Clinical-Etiology-Anatomy-Pathophysiology (CEAP) class and venous clinical severity score. Results Of the initial 126 patients, there were 65 patients with 24 month follow-up. Of these 65 patients, 70% were female, with a mean age of 70 ± 14 years and an average body mass index (BMI) of BMI of 30.5 ± 6. The mean great saphenous vein diameter in the upper thigh was 7.6 mm and the mean treatment length was 39 cm. Adjunctive treatment of the varicosities was performed in 14% of patients during the procedure. Closure rates were 100% at one week, 98% at three months, 95% at 12 months, and 92% at 24 months. There was one patient with complete and four with partial recanalization ranging from 7 to 12 cm (mean length 9 cm). There was significant improvement in CEAP and venous clinical severity score (P < .001) for all time intervals. Conclusion Early high occlusion rate with mechanochemical ablation is associated with significant clinical improvement which is maintained at 24 months, making it a very good option for the treatment of great saphenous vein incompetence.

Abstract
OPINION STATEMENT Minimally invasive endothermal treatments have replaced surgical ligation and stripping in the management of chronic venous insufficiency (CVI) and are now considered the standard of care. Newer techniques have emerged in the last few years in an attempt to further minimize the procedural discomfort associated with endothermal procedures. These new techniques are designed to avoid tumescent anesthesia (TA). These new non-thermal, tumescentless techniques are well tolerated and are shown to result in equivalent outcomes when compared to the thermal ablations. Since there is no data to support the argument that one of these therapies is truly superior to another, selection of a particular thermal or non-thermal technique is dependent on patient and physician preferences. Adoption of a particular non-thermal procedure is also dependent on other factors such as the learning curve, initial setup costs, overall cost-effectiveness and reimbursement. Once the reimbursement issues are resolved and durability is confirmed, these techniques have the potential to become the new standard of care for the management of CVI.

Abstract
In July 2013, the National Institute of Health and Clinical Excellence (NICE) recommended “endothermal” ablation (meaning endovenous thermal ablation) is the first line treatment for truncal venous reflux in varicose veins. The initial endovenous thermoablation devices were radiofrequency ablation and endovenous laser ablation. More recently, Glue (cyanoacrylate), endovenous steam and Clarivein (mechanochemical ablation or MOCA) have entered the market as new endovenous techniques for the treatment of varicose veins. Glue and Clarivein do not require tumescent anaesthesia and do not use heat and therefore termed non-tumescent non-thermal (NTNT). Steam both requires tumescence and is also a thermal technique (TT). This article reviews the current position of these 3 new technologies in the treatment of varicose veins.
