Recurrent Recanalization After Endovenous Thermal Ablation for Recanalized Varicose Veins

Endovenous thermal ablation (ETA) in the form of radiofrequency (RFA) or endovenous laser (EVLA) are being used more frequently treatment venous insufficiency. Studies capturing rates thrombotic complications and recanalization can be found literature. However, data lacking regarding risk after ETA, further options available. We hereby present our subsequent repair recanalized insufficient lower limb veins. Re-canalized patient from 2012 to 2022 treated practice were collected for retrospective analysis. Recanalized patients undergoing ETA operations analyzed reintervention. Data was follow-up visit within 1 week procedure, every 3 months first year, 6 thereafter. Flow >500 ms greater saphenous vein, short accessory vein considered as recanalization. >350 perforator re-canalization. Correlations made age, gender, laterality, presenting symptoms targeted vein. captured 13,335 procedures, those 203 240 redo procedures; 145 female, 117 performed on left extremity 123 right extremity. The median body mass index 32.2 kg/m2 (interquartile range [IQR], 9.7 kg/m2). age 61.5 years (IQR, 19.25 years). Clinical, Etiology, Anatomy, Pathophysiology (CEAP) class C2, C3, C4, C5, C6 2, 76, 111, 6, 45 patients, respectively. Of 73 using EVLA 167 RFA. initial technical success 97.6% (13,020/13,335), rate 95.4% (229/240). veins operated on, 138 52 34 16 No correlation between successful obliteration with repeat procedures CEAP class, vs closure higher than recurrent rate. Lower insufficiency acceptable by ETA. Further need validate finding. Patients should informed decreased intervention.
