To review the clinical experience and early outcomes of endothermal perforator ablation.
Method
Retrospective review of an endovenous practice from 2007-2019. Clinically significant incompetent perforators were treated by Endovenous Laser Ablation (EVLA), or segmental radiofrequency ablation (RFA).
Result
Complete data were available for 110 of the 116 symptomatic incompetent perforating veins treated. Radiofrequency ablation of 20 perforators produced a 55% perforator closure rate, while 90 EVLA perforator ablations resulted in a closure rate of 80%. Closure rates with EVLA varied by location and perforator length. Closure rates for truncal ablation were 95.5% for RFA and 97.2% for EVLA.
Conclusion
Early closure rates following endothermal ablation of incompetent lower limb perforating veins are lower than those obtained for truncal ablation. EVLA perforator closure appears to be more effective than segmental RFA in most situations but short treatment lengths and location at the ankle are associated with the poorest outcomes.
