ObjectiveTo determine the most effective modality of intervention to treat saphenous vein insufficiency.Summary Of Background DataEndovenous therapies have instigated a paradigm shift in the management of superficial venous incompetence. When compared with open surgery, endovenous interventions (foam sclerotherapy, radiofrequency ablation, endovenous laser ablation (EVLA), mechanochemical ablation, and CAE closure) potentially offer reduced morbidity with similar procedural efficacy.MethodsA systematic review and series of network meta-analyses of randomized controlled trials were performed assessing risks of procedural failure (within 6-weeks) and recurrence (6-weeks to 5-years), defined by ultrasound, between the different modalities of intervention for superficial venous incompetence. Treatment comparisons addressing risks of common adverse events, venous clinical severity score, and pain were also performed.ResultsA systematic search identified 51 articles, describing 36 randomized controlled trials, incorporating 7576 limbs. Outcome data on 10 modalities of intervention were analyzed up to 5-year follow-up. CAE resulted in the lowest risk of procedural failure within 6-weeks. Foam sclerotherapy had the highest risk of recurrence while high ligation with stripping (HLS) and Conservatrice Hemodynamique de l'Insuffisance Veineuse en Ambulatoire were ranked best to reduce long-term recurrence. No intervention increased risks of venous thromboembolism and there was minimal difference in morbidity between treatments. All interventions improved venous clinical severity score (range -1.02 to -4.95), however, radiofrequency ablation demonstrated the greatest improvement, followed by EVLA and HLS between 2 to 5-years. EVLA was associated with the highest risk of pain, while mechanochemical ablation offered the least.ConclusionsAlthough CAE offered the lowest risk of initial procedural failure, HLS resulted in lower rates of long-term recurrence without considerably increasing morbidity when compared with other endovenous options.Copyright © 2021 Wolters Kluwer Health, Inc.
