Abstract (EN): Introduction: Presence of varices after operative treatment (PREVAIT) is a common finding after varicose vein surgery, and has been shown to significantly reduce the quality of life of those it affects. As such, long-term results after varicose vein interventions have to be taken into account when choosing a technique. This study aims to systematically review current evidence on the recurrence of varicose veins after three different techniques: conventional surgery (HLS), endovenous laser ablation (EVLA) and radiofrequency ablation (RFA).Evidence acquisition: A literature search was performed on the PubMed and Web of Science databases, which returned 546 studies. Fourteen studies were included. Data were extracted using predefined forms.Evidence synthesis: A total of 2795 patients were included, for a total of 3056 legs treated. 503 legs (16.5%) were treated by HLS, 1791 (58.6%) by EVLA and 762 (25.0%) by RFA. PREVAIT was reported in 34.4% for patients treated by HLS, for a mean follow-up comprised between 18 months and 5 years; 16.6% by EVLA, for a mean follow-up between 112 days and 5 years and 6.7% of those treated by RFA, for a mean follow-up between 106 days and 5 years. Regarding patterns of recurrence, the development of new varicose veins was the most commonly reported mechanism of recurrence after HLS (range: 29.8-91%) and EVLA (range: 40-81.6%), but not RFA, where recanalization of the occluded saphenous trunk accounted for up to 67.0% of the cases. Only one study reported quality of life related recurrence, and included patients treated by HLS and EVLA, but not RFA. Aberdeen Varicose Vein Questionnaire (AVVQ) score, physical functioning domains of the SF-36 score and patient satisfaction were significantly worse in patients with clinical recurrence. Re-intervention rates after recurrence were reported in 5 studies, ranging between 7.7% and 37.7% for HLS and 0-57.0% for EVLA. Only one study reported data on re-intervention for RFA patients, which was 6.67%.Conclusions: Recurrence is a reliable indicator of long-term efficacy of a varicose vein treatment and appears to occur more frequently after HLS. Although there are several mechanisms of recurrence, the development of new varicose veins was the most commonly observed. There is clear heterogeneity among definitions of recurrence and follow-up periods in literature.
