Abstract
Insufficiency of the small saphenous vein causes 15% of varicose veins in the lower extremities. Endovenous ablation for the treatment of small saphenous vein varices has become a trend, and an increasing number of studies have reported the effects of different types of endovenous ablation in patients with small saphenous varicose veins. The purpose of this systematic review is to summarize the results of existing studies on endovenous ablation for the treatment of small saphenous varicose veins, compare its role and efficacy, and provide insights into the future development of endovenous ablation for treating small saphenous varicose veins. A systematic review of literature published from January 1, 2002 to January 1, 2022 was conducted from PubMed, Embase, and China Academic Journals full-text databases. The pre-determined inclusion criteria were clinical literature of endovenous ablation for treating small saphenous varicose veins. Keywords included "ablation", "small saphenous vein", "lesser saphenous vein", "short saphenous vein", "xiaoyinjingmai" and "xiaorong". Of the 506 articles screened, 33 articles were included in this review: 19 articles were related to endovenous laser ablation, five were related to mechanochemical ablation, seven were related to radiofrequency ablation, and two were related to both endovenous laser ablation and radiofrequency ablation. The anatomical success rate of endovenous laser ablation, radiofrequency ablation, and mechanochemical ablation were 94.3%, 96.0%, and 88.1%, respectively, and the heterogeneities were all moderate. Most of the current studies are of a low-quality level of research. Hence, long-term follow-up studies and large-scale randomized controlled trials are required to obtain high-quality evidence. Although the gold standard for the treatment of small saphenous vein insufficiency remains unclear, endovenous ablation is still the recommended method.

Abstract
Objectives Aim was to report a prospective two-centre Singaporean experience using Endovenous Microwave Ablation (EMA) to treat symptomatic primary great saphenous vein reflux. We evaluated 1-year safety, efficacy and patient satisfaction. Methods 50 patients (63 limbs; 29 females; mean age 58.0 ± 12.1 years) were included. Patients were reviewed at 2-weeks, 3-, 6- and 12-months and underwent Duplex ultrasound assessment. Three quality of life (QoL) questionnaires were completed. Results The truncal closure rates at 2-weeks, 3-, 6- and 12-months were 63/63 (100%), 59/59 (100%), 58/58 (100%) and 59/60 (98.3%), respectively. There was 100% technical success and no serious adverse events. There were sustained improvement of QoL questionnaire scores from 2 weeks to 12 months. Conclusion EMA is a safe and efficacious venous ablative technology at 12 months and is associated with a high rate of target vein occlusion and sustained QoL improvement.

A multicenter, randomized, dose-finding study of mechanochemical ablation using ClariVein and liquid polidocanol for great saphenous vein incompetence. J Vasc Surg Venous Lymphat Disord 2021; 10:856-864.e2. [PMID: 34781008 DOI: 10.1016/j.jvsv.2021.10.016] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 10/31/2021] [Indexed: 01/11/2023]
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
OBJECTIVE We present 12 months efficacy data from A Singapore VenaSeal™ real-world post-market evaluation Study (ASVS), a prospective single-arm Asian population registry aimed to evaluate cyanoacrylate glue (CAG) closure of refluxing truncal veins. METHODS Duplex ultrasound was used to assess truncal vein closure. The revised Venous Clinical Severity Score (rVCSS) and three quality of life (QoL) questionnaires were completed to assess improvement in venous disease symptoms. RESULTS 90/100 (90%) patients (136 legs; 140 truncal veins) completed evaluation at 6- and 12 months. The truncal closure rates at 6 and 12 months were 139/140 (99.3%) and 137/140 (97.9%), respectively. rVCSS and QoL questionnaires scores were sustained from the 3 to 12 months visits, although there were no futher significant improvement. No serious adverse events were reported between 3 and 12 months. CONCLUSIONS CAG remains a safe and efficacious venous ablative technology at 12 months and is associated with a high rate of target vein occlusion and sustained QoL improvement.

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
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
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.
