Objectives This study assessed the effectiveness and patient experience of the ClariVein® endovenous occlusion catheter for varicose veins from a large single-centre series in the UK. Methods A total of 300 patients (371 legs) underwent ClariVein® treatment for their varicose veins; 184 for great saphenous vein (GSV) incompetence, 62 bilateral GSV, 23 short saphenous vein (SSV), 6 bilateral SSV and 25 combined unilateral great saphenous vein and SSV. Patients were reviewed at an interval of two months post procedure and underwent Duplex ultrasound assessment. Postoperative complications were recorded along with patient satisfaction. Results All 393 procedures were completed successfully under local anaesthetic. Complete occlusion of the treated vein was initially achieved in all the patients, but at eight weeks’ follow-up, there was only partial obliteration in 13/393 (3.3%) veins. These were all successfully treated with ultrasound-guided foam sclerotherapy. Procedures were well tolerated with a mean pain score of 0.8 (0–10). No significant complications were reported. Conclusions ClariVein® can be used to ablate long and short saphenous varicose veins on a walk-in–walk-out basis. Bilateral procedures can be successfully performed, and these are well tolerated as can multiple veins in the same leg. Early results are promising but further evaluation and longer term follow-up are required.

Objective This report aims to present the early results of a retrospective study of the use of N-butyl cyanoacrylate (VariClose®)-based non-tumescent endovenous ablation for the treatment of patients with varicose veins. Method One hundred and eighty patients with varicose veins due to incompetent saphenous veins were treated with the VariClose® endovenous ablation method between May 2014 and November 2014. The patient sample consisted of 86 men and 94 women, with a mean age of 47.7 ± 11.7 years. The patients had a great saphenous vein diameter greater than 5.5 mm and a small saphenous vein diameter greater than 4 mm in conjunction with reflux for more than 0.5 s. Patients with varicose veins were evaluated with venous duplex examination, Clinical, Etiological, Anatomical and Pathophysiological classification (CEAP), and their Venous Clinical Severity Scores were recorded. Results The median CEAP score of patients was three, and the saphenous vein diameters were between 5.5 and 14 mm (mean of 7.7 ± 2.1 mm). A percutaneous entry was made under local anesthesia to the great saphenous vein in 169 patients and to the small saphenous vein in 11 patients. Duplex examination immediately after the procedure showed closure of the treated vein in 100% of the treated segment. No complications were observed. The mean follow-up time was 5.5 months (ranging from three to seven months). Recanalization was not observed in any of the patients during follow-up. The average Venous Clinical Severity Scores was 10.2 before the procedure and decreased to 3.9 after three months (p < 0.001). Conclusion The application of N-butyl cyanoacrylate (VariClose®) is an effective method for treating varicose veins; it yielded a high endovenous closure rate, with no need for tumescent anesthesia. However, long-term results are currently unknown.

Objectives The purpose of this study was to determine the long-term efficacy, safety and rate of recurrence for varicose veins associated with great saphenous vein (GSV) reflux treated with ultrasound-guided foam sclerotherapy (UGFS). Methods A five-year prospective study was performed, recording the effect on the GSV and saphenofemoral junction (SFJ) diameters, and reflux in the superficial venous system over time. UGFS was the sole treatment modality used in all cases, and repeat UGFS was performed where indicated following serial annual ultrasound. Results No serious adverse outcomes were observed – specifically no thromboembolism, arterial injection, anaphylaxis or nerve damage. There was a 4% clinical recurrence rate after five years, with 100% patient acceptance of success. Serial annual duplex ultrasound demonstrated a significant reduction in GSV and SFJ diameters, maintained over time. There was ultrasound recurrence in 27% at 12 months, and in 64% at five years, including any incompetent trunkal or tributary reflux even 1 mm in diameter being recorded. Thirty percent had pure ultrasound recurrence, 17% new vessel reflux and 17% combined new and recurrent vessels on ultrasound. Of all, 16.5% required repeat UGFS treatment between 12 and 24 months, but less than 10% in subsequent years. The safety and clinical efficacy of UGFS for all clinical, aetiological, anatomical and pathological elements classes of GSV reflux was excellent. Conclusion The popularity of this outpatient technique with patients reflects ease of treatment, lower cost, lack of downtime and elimination of venous signs and symptoms. Patients accept that UGFS can be repeated readily if required for recurrence in this common chronic condition. The subclinical ultrasound evidence of recanalization or new vein incompetence needs to be considered in this light.

Introduction: Endovascular ablation of varicose vein either by radiofrequency ablationor laser delivers sufficient thermal energy to incompetent vein segments to produce irreversible occlusion, fibrosis and ultimately disappearance of the vein.Materials and Methods: Three hundred patients with varicosities due to primary or recurrent sapheno-femoral or sapheno-popliteal junction and great or small saphenous veinreflux underwent out-patient and in-patient endovenous thermal ablation between January 2015 to December 2017.The great saphenous vein was ablated from 2-2.5 cm below sapheno-femoral junction to knee and the small saphenous vein was ablated from mid-calf to the sapheno-popliteal junction.Results: Patient returning time to normal activity was 0–1 days returning to normal daily activity were immediately after 4 hours. Duplex ultrasound follow-up (median 3-months) confirmed abolition of sapheno-femoral junction/great saphenous vein and sapheno-popliteal junction/small saphenous vein reflux in all limbs. There were no instances of skin burns or deep vein thrombosis, but, 7 patients developed transient cutaneous numbness involving sural nerve and 1 developed endovenous heat induced thrombosis 3.Conclusions: This is likely to be more effective than conventional surgery, although long-term follow up is required.  Despite being expensive in comparison to open surgery, endovenous thermal ablation is superior in terms of: minimizing pain, avoiding incision, early mobilisation and discharge. Changing the treatment distance from 2 cm to 2.5 cm peripheral to the Deep veins junction may result in a diminished incidence of endovenous heat induced thrombosis 3.

Objectives: Foam sclerotherapy of the great saphenous vein is a relatively new and promising treatment option for patients with axial reflux. Its usefulness may be limited by low primary occlusion rates. We present a standard technique for catheter-directed foam sclerotherapy, which facilitates foam delivery precisely to its intended site of action and potentially improves occlusion rates. Methods: A consecutive series of 53 patients were treated with foam sclerotherapy using a standard technique for foam delivery at Malmö University Hospital between September 2006 and April 2007. Patients were treated with 3% polidocanol foam through an introducer sheath, which was inserted percutaneously over a guidewire in the great saphenous vein (GSV). All successfully treated patients were examined by colour duplex one week after the procedure. Results: Primary technical success with delivery of foam along the length of the GSV was achieved in 50 of 53 limbs (94%). All treated GSVs were occluded at one week duplex. Conclusion: The use of an endovascular sheath inserted percutaneously over a guidewire under duplex ultrasound control is feasible in most patients and has resulted in high primary occlusion rates.

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.

Purpose Endovascular ablation of the great saphenous vein has been proposed as a less invasive alternative to conventional ligation and stripping of varicose veins. Outcomes of patients treated with the radiofrequency ablation ClosureFast™ system over an eight-year period from a single-center were evaluated. Methods Three-year follow-up data included duplex ultrasound scan, complication rate, and questionnaires to assess patients’ QOL, level of pain, and days off work. Results A total of 1080 consecutive patients (49.5 ± 18.6 years, 72% female, mean body mass index: 25.44 ± 4.1 kg m−2) underwent radiofrequency ablation for incompetent saphenous veins in a single institution. Occlusion of the great saphenous vein was obtained in 98.6% and 93.8% cases at the end of the procedures and within 36 months, respectively. Only three deep venous thromboses and minor complications occurred in this series throughout the first week from the procedure. A decrease of the external vein diameter, equal to 72.7% and 31.1% of the pretreatment diameter, was observed at 1 week and 36 months, respectively. The average Aberdeen Varicose Vein Questionnaire score improved from 18.06 ± 9.47 before treatment to 11.56 ± 10.23 at 12 months, with no significant differences in the subsequent follow-up. SF-36 QOL scores significantly improved after the procedure in all domains, while there were no changes over time. Patients reported a prompt return to normal daily activities (1.5 ± 0.7 days) and work (3.1 ± 1.9 days). Body mass index influenced QOL scores, while it did not affect great saphenous vein diameter reduction during the follow-up. On the contrary, Clinical Etiologic Anatomic Pathophysiologic class significantly influenced both great saphenous vein diameter reduction after the treatment and QOL scores within 36 months. Conclusion Results of this retrospective monocentric, large patients study suggest that radiofrequency ablation of the great saphenous vein may be a safe and efficient alternative to conventional surgery.

Objectives To determine great saphenous vein occlusion rate after endovenous laser ablation using the 1470-nm bare-fiber diode laser to supply either 7 W or 15 W and evaluate procedure-related complications. Method Patients with varicose veins of the lower extremities (CEAP class C2–C6) were randomly assigned to undergo either 7-W (18 patients, 30 limbs) or 15-W (18 patients, 30 limbs) endovenous laser ablation. Duplex ultrasound follow-up was at 3–5 days, 1, 6, and 12 months postoperatively. Results Occlusion rate was 100% in both groups at 3–5 days and 1 month and 86.7% in 7-W and 100% in 15-W patients at both 6 and 12 months, with no difference between groups ( p > 0.05). Four (13.3%) 15-W and 3 (10%) 7-W patients had paresthesia at 3–5 days, with no difference between groups ( p > 0.05). Conclusions These preliminary data suggest that both techniques are similarly effective in the treatment of varicose great saphenous veins.

Objective This retrospective study presents the long-term results of catheter-directed foam sclerotherapy of the great saphenous vein. Method From January 2003 to June 2017, 277 patients with varices and great saphenous vein incompetence were treated with echo-guided foam sclerotherapy. Forty-six patients were treated with long-catheters guided by foam sclerotherapy. Foaming was carried out with sodium-tetra-decyl-sulphate. Results Results were examined in the two groups: A (long-catheters) and B (other procedures). The median overall follow-up was 52.1 months. In the A-group, the complete occlusion rate was 34/46 pts (73.9%) and partial occlusion was 10/46 (21.7%). In the B-group, respectively, 130/231 (56.2%) and 90/231 (38.9%). Comparisons between groups were statistically significant (p = 0.023; p = 0.021). Failures involved, respectively, 2/46 (4.3%) and 11/231 (4.7%) with no statistical significance. The complication rates were similar in the two groups. Conclusions In this long-term experience (median follow-up exceeding four years), foam-guided sclerotherapy of the great saphenous vein with a long-catheter turned out to be more effective than the usual foam-guided sclerotherapy.

Objective To describe the mid-term outcome after inferior selective crossectomy in a subset of patients with symptomatic chronic venous disease and both great saphenous vein and suprasaphenic valve incompetence. Methodsː Retrospective analysis of prospectively collected data was conducted. During an eight-year period, 1095 ligations of all saphenofemoral junction inferior tributaries and great saphenous vein stripping were performed in 814 Clinical, Etiology, Anatomy, Pathophysiology C2–C6 patients. Duplex ultrasound follow-up examinations were performed after 30 days, 6 months, and 2 years, and saphenofemoral junction hemodynamic patterns and varicose veins recurrence rates were evaluated. Results Two hundred and twenty patients completed the two-year follow-up period. At the 30-day Duplex ultrasound evaluations, two different hemodynamic patterns were described. Type 1, with physiological drainage of saphenofemoral junction superior tributaries, was observed in 214 patients. Type 2, without flow in saphenofemoral junction superior tributaries, was observed in six patients. Overall varicose vein recurrence rates were 0, 2.3, and 2.7% at the 30-day, 6-month, and 2-year follow-up examinations, respectively. At the two-year follow-up, Type 1 patients showed 0% varicose vein recurrence, while Type 2 patients showed 100%. Conclusionsː Inferior selective crossectomy seems to be a valid and safe option in case of both suprasaphenic valve and great saphenous vein incompetence. Duplex ultrasound evaluation, according to our protocol, allows us to identify two different saphenofemoral junction hemodynamic patterns that could predict varicose vein recurrence at mid-term. An optimal stump washing after inferior selective crossectomy, warranted by patency and large caliber saphenofemoral junction superior tributaries, seems to be the key point in preventing varicose vein recurrence in this context. However, large prospective studies regarding saphenofemoral junction modifications and varicose vein recurrence are needed to confirm these preliminary observations.
