Combined Endovenous Laser and Mechanochemical Ablation to Reduce Sclerosant for Three or Four Veins with Chronic Venous Insufficiency

Background: A large amount of sclerosant is needed for the treatment of saphenous vein insufficiency with mechanochemical ablation (MOCA) for three or four veins with chronic venous insufficiency. In addition, what constitutes a safe amount is not clearly defined. In this study, we evaluate the feasibility of the combined endovenous laser and mechanochemical ablation to reduce the amount of sclerosant as compared with mechanochemical ablation monotherapy. Methods: A total of 327 patients diagnosed with superficial vein insufficiency between June 2018 and May 2020 and treated in a single center by one surgeon were evaluated retrospectively. There were 130 patients included who were treated with mechanochemical ablation (MOCA, Group I) and 197 patients who were treated with combined endovenous laser ablation and mechanochemical ablation (EVLA and MOCA, Group II). Results: The amount of sodium tetradecyl sulfate (STD) used per number of limbs was 5.5 ± 2.05 mL in Group I and 4.51 ± 1.2 mL in Group II (p < 0.001). The amount of STD used per number of veins was 4.77 ± 1.91 mL versus 3.12 ± 1.02 mL in Groups I and II, respectively, (p < 0.001). Recanalization rates within 52 weeks were 0% (0/130) in Group I and 5.58% (11/197) in Group II, while after 52 weeks they were 2.31% (3/130) in Group I and 6.60% (13/197) Group II and were not statistically significant. Complications within 4 weeks were 3.84% and 7.11% in Groups I and II, respectively. Conclusions: The results of this study show that combined EVLA and MOCA reduces the amount of sclerosant per the number of veins and legs treated as compared with MOCA monotherapy for three or four veins with chronic venous insufficiency. The combined EVLA and MOCA treatment in patients with three or four varicose veins has few side effects, reduces the amount of sclerotic agent, and can be considered to be an effective treatment method for inducing venous occlusion.

Choosing Wisely in France, for the Treatment of Saphenous Vein Insufficiency and Recurrences

AbstractChoosing wisely is an idea originally created in North America. It was designed to help maintaining a dialogue with patients to allow taking best decisions in the care and treatment of patients. As a consequence, despite guidelines outlining evidence of different treatments, choosing wisely takes the patient’s point of view into the focus and helps priorising therapeutic strategies in the context of specialisation, country, reimbursement and culture.In France this dialogue was performed under the auspices of the National Professional Council of Vascular Medicine (CNPMV- Conseil National Professionnel de Médecine Vasculaire), which brings together all the societies of vascular medicine in France (representing, more than 2,000 vascular doctors).They have elaborated 10 recommendations to choose wisely regarding the treatment of saphenous veins insufficiency and recurrences. The history, discussion and results are presented in this article.

Comparison of Non-Tumescent n-Butyl Cyanoacrylate and Endovenous Laser Therapy in Saphenous Vein Ablation

Objective: Ablation of N-butyl cyanoacrylate (NBCA) and endovenous laser ablation (EVLA) are two important techniques used in the treatment of venous insufficiency. The aim of this study is to compare the results of EVLA and NBCA methods in the treatment of saphenous vein insufficiency. Method: 739 patients with saphenous vein insufficiency who were followed up between 2013 and 2018 and treated with NBCA (350 patients) and EVLA (389 patients) applications were included in the study. Pre-procedure, during, post-procedure and follow-up data of the patients were collected and compared retrospectively. Results: In the group using NBCA technique; mean age was 46.09±6.12 years, mean age was 48.08±6.11 years in the EVLA technique group. The mean ablated vein length was 32.97-65.83 cm in the NBCA group and 30.65-67.25 cm in the EVLA group. The mean procedure time was 7 minutes in the NBCA group and 18 minutes in the EVLA group. The 12-month total occlusion rates in the NBCA and EVLA groups were 98.8% and 97.6%, respectively. In both the NBCA and EVLA groups, the post-procedure Venous Clinical Severity Score (VCSS) was significantly reduced with no difference between the groups. When NBCA treatment was compared with EVLA treatment, it was seen that there may be fewer side effects after NBCA treatment. Conclusion: When the treatment success rates, application times, complication rates and venous clinical severity scoring results in the data obtained in our study were evaluated, it was thought that the NBCA method was as successful and reliable as the EVLA method. In conclusion; It has been suggested that the vascular closure system with NBCA is a fast and effective treatment method in the treatment of saphenous vein insufficiency, as it does not require tumescent anesthesia, does not require compression stockings, and does not have the risk of paresthesia, burn scars or pigmentation.

VariClose® vein sealing system is inferior to endovenous laser ablation for the treatment of varicose veins

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. Retrospective non-randomized single center study with prospectively collected data comparing endovenous laser treatment and VariClose® procedures between April 2018 and November 2019. 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). VariClose® vein sealing system is inferior to endovenous laser treatment as a treatment option for varicose veins as it has a higher recanalization rate.

Effect of saphenous vein diameter and reflux time on stump length after cyanoacrylate closure.

Cyanoacrylate closure (CAC) has recently been introduced for the treatment of incompetent saphenous veins. The purpose of the present study is to investigate the correlation of the saphenous vein diameter and reflux time (RT) with the stump length after CAC. A retrospective review was performed using prospectively collected data of CAC patients. The pre-operative saphenous vein diameter and RT were measured. The stump length was measured immediately after the procedure and at 1 week. Pearson's correlation analysis was applied to determine the correlation between the saphenous vein diameter or RT and stump length. A total of 32 saphenous veins were closed in 21 patients, 15 of whom were female. The mean age was 56.9±12.6 years (range, 31-73 years). Complete closure was achieved in all patients. The pre-operative mean diameter was 7.0±2.2 mm. The mean stump lengths were 26.1±10.2 and 28.1±13.6 mm on post-operative days 0 and 7, respectively (P=0.002). The Pearson coefficients for the correlation between the saphenous vein diameter and stump length on post-operative days 0 and 7 were 0.528 (P=0.005) and 0.177 (P=0.430), respectively. Furthermore, the Pearson coefficients for the correlation between the RT and stump length on post-operative days 0 and 7 were -0.215 (P=0.282) and 0.019 (P=0.938), respectively. In conclusion, CAC is effective modality for the treatment of saphenous vein insufficiency. The stump length increased with the diameter of the saphenous veins, while the RT had no marked effect on the stump length. Therefore, the glue injection should be initiated from the instructed position to avoid glue extension into deep veins and to prevent elongating the stump length.

Two-year follow-up of a n-butyl-2-cyanoacrylate glue ablation for the treatment of saphenous vein insufficiency with a novel application catheter with guiding light.

Objectives This study aims to present the early results of a prospective study of the use of novel n-butyl-2 cyanoacrylate (VenaBlock)-based nontumescent endovenous ablation with a guiding light for the treatment of patients with varicose veins. Methods Five hundred and seventy-three patients with lower-limb venous insufficiency were treated within in the previous four years. The study enrolled adults aged 21–70 years with symptomatic moderate to severe varicosities (C2–C6 patients clinical, etiological, anatomical, and pathophysiological classification) and great saphenous vein reflux lasting longer than 0.5 s with great saphenous vein diameter ≥ 5.5 mm assessed in the standing position. Duplex ultrasound imaging and clinical follow-up were performed on the third day, first month, and sixth month. Clinical, etiological, anatomical, pathophysiological classification; venous clinical severity score; and completed Aberdeen varicose vein questionnaire were recorded. Results Five hundred and seventy-three patients aged 21–70 years with lower-extremity venous insufficiency treated with n-butyl-2. The mean treatment length was 30.6 ± 5.3 cm and the average n-butyl-2 delivered was 1.2 ± 0.3 ml. The mean procedure time was 10.8 ± 4.7 min. There was no deep venous thrombosis, pulmonary embolism, or paresthesia. We observed ecchymosis in eight patients (1.4%) at the entry site at the third day follow-up. Phlebitis was encountered with 10 (1.8%) patients. No skin pigmentation, hematoma, paresthesia, deep-vein thrombosis, or pulmonary embolism was observed. Procedural success was 100%, and complete occlusion was observed after treatment, at the third day follow-up and at first month. Kaplan–Meier analysis yielded with overall clinical recurrence-free rate after a mean follow-up of 23.96 months was 99.38%. All patients had significant improvement in venous clinical severity score and quality-of-life scores postoperatively ( p < 0.0001). Venous clinical severity score scores at preintervention and 24th month were 5.8 ± 1.0 (range 4–8) and 0.6 ± 0.6 (range 0–4), respectively ( p < 0.0001). Aberdeen varicose vein questionnaire scores at preintervention and 24th month were 19.7 ± 6.4 (range 9–30) and 4.4 ± 1.1 (range 1–9), respectively ( p < 0.0001). Conclusions The procedure appears to be feasible, safe, and efficient in treating the great majority of incompetent great saphenous veins with this technique.

Utility of Adjunctive Digital Subtraction Venography for the Treatment of Saphenous Vein Insufficiency

Purpose: To report the use of adjunctive venography for the treatment of superficial venous reflux. Methods: Two hundred consecutive patients (mean age 60.9 years, range 33–86; 128 women) with chronic venous disease underwent saphenous or perforator vein ablation in 268 limbs (305 venous trunks) guided by adjunctive venography and fluoroscopy in addition to ultrasound between October 2010 and May 2016. Intraprocedural venograms were independently evaluated by 2 vascular specialists to identify the presence of venous anomalies and the need for fluoroscopy-guided maneuvers to successfully complete venous ablation. Intraprocedural venography results were compared with preoperative venous duplex scan reports to ascertain if the duplex study could be of value in identifying preoperatively any anatomical variants that may pose a technical challenge to the operator. Results: In this cohort, 542 venograms (2.0/limb) were performed with a mean duration of 4.9±9.1 minutes (range 1–48). Two thirds of patients (132, 66%) had anomalies or abnormalities within the target vein; more than a third (88, 44%) required an endovascular maneuver to successfully complete the ablation and 17% (34) of cases were impossible to complete without adjunctive fluoroscopic guidance. Per-patient comparison of intraprocedural venography with preoperative venous duplex reports identified 21 (11%) patients with abnormalities detected on ultrasound (23 anomalies) compared with 123 (64%) on venography (193 anomalies). This gave ultrasound a 17.1% sensitivity, 100% specificity and positive predictive value, and 40.7% negative predictive value. Conclusion: Venography is a valuable addition to ultrasound to facilitate complete ablation of insufficient saphenous veins in selected patients with complex anatomy.

CHIVA treatment of saphenous vein insufficiency with aneurysm of the great saphenous vein in von Willebrand’s disease

SummaryIn patients with an increased tendency to bleeding and severe varicose veins, even the minimally invasive venous procedure CHIVA requires careful planning and risk assessment. CHIVA treatment is reported in a 67-year-old female patient with aneurysm of the great saphenous vein at the saphenofemoral junction, reflux above and below the knee (Hach III), skin changes (C4a) and von Willebrand’s disease. Radiofrequency was used over a 13 cm segment in the proximal great saphenous vein. The result shows a reduction in the diameter of the great saphenous vein at the thigh from 8.2 to 5.4 mm and an absence of reflux and absence of clinic. Even in patients with severe findings, a minor procedure can achieve a good clinical result with low risk.

Early-Term Outcomes for Treatment of Saphenous Vein Insufficiency with N-Butyl Cyanoacrylate: A Novel, Non-Thermal, and Non-Tumescent Percutaneous Embolization Technique.

The purpose of this study was to present early-term outcomes of VariClose® Vein Sealing System, which is a novel, non-thermal, and non-tumescent percutaneous embolization technique for treatment of saphenous vein insufficiency. Between March 2014 and July 2015, 189 saphenous veins in 141 patients were treated with Variclose Vein Sealing System containing n-butyl cyanoacrylate. Pre-, intra-, post-procedural, and follow-up data of patients were collected and retrospectively reviewed. Mean age of patients was 42.5 ± 14.0 years, of which 53% were female. Technical success rate of intervention was 98.9%. Mean procedure time was 14.3 ± 7.5 minutes. Eighty-nine percent of patients (n = 126/141) were available at mean follow-up time of 6.7 months. Mean Venous Clinical Severity Score was significantly improved from 8.3 ± 2.2 at pre-procedure period to 3.3 ± 1.8 at follow-up. No complete recanalization was observed, but 2 patients were presented with partial recanalization during follow-up. The complete occlusion rate was 98.4%. No serious adverse event related to procedure was observed. Variclose Vein Sealing System appears to be safe and effective in treatment of saphenous vein insufficiency. Further randomized studies with long-term outcomes are required for determining optimal treatment modality in patients with saphenous vein insufficiency.

Investigation on Radiofrequency and Laser (980 nm) Effects after Endoluminal Treatment of Saphenous Vein Insufficiency in an Ex-vivo Model

An ex-vivo model for the experimental evaluation of endoluminal thermal procedures for occlusion of saphenous veins was developed. Radiofrequency obliteration (RFO) and endovenous laser therapy (ELT) were compared using this model. Experimental ex-vivo treatment study. The model consists of the subcutaneous foot veins from freshly slaughtered cows which were reperfused in situ with heparinised bovine blood. The veins were treated with either radiofrequency (RFO n=5) or with endoluminal 980 nm laser light (ELT n=5) using a continuous pull-back for RFO and a stepwise illumination and pull-back protocol for ELT. Immediately after treatment perivenous tissue and veins were examined macroscopically. In a second study the same treatment parameters were used in four further vein segments with RFO (n=2) and ELT (n=2). These vein segments were examined microscopically in HE-stained histological sections. Induration of the vessel wall and contraction of the vessel lumen were observed after RFO. Laser treatment produced carbonised lesions of the vein wall. After 12-24 laser exposures these lesions often became transmural, causing complete perforation of the vessel wall. Histological evaluation after radiofrequency treatment demonstrated homogenous circular thermal tissue alteration with disintegration of intima and media structures. Histological evaluation after endovenous laser treatment showed large variations of thermal tissue effects. Tissue effects ranged from major tissue ablation and vessel wall disruption to minor effects located between laser exposures and on the opposite vessel wall. Our model is suitable for systematic scientific evaluation of endovenous thermal occlusion procedures. Our first results and theoretical considerations indicate that endovenous laser treatment should be modified in order to ensure controlled homogenous circular thermal damage, avoiding vessel wall perforation and damage to perivascular structures.
