Comparative studies of endovenous thermal ablation techniques with laser (EVLA) and radiofrequency (RFA), for the treatment of varicose veins.

The methods of endovenous thermal ablation have now replaced open surgery in the treatment of varicose veins. The advantages of endovenous thermal ablation methods are application in non-hospital settings, short hospitalization, recovery rates and low complication levels. The purpose of the present study was to review comparative studies for two methods of endovenous thermal ablation, laser ablation (EVLA) and thermal radiofrequency ablation (RFA). Twelve (12) studies published in 2008-2018 were analyzed, including a systematic review, an experimental study, four retrospective non-randomized trials and six randomized controlled trials. Regarding the efficiency of thermal ablation, this seems to be similar for both methods, although there is insufficient evidence. Some studies find higher recurrence rates in the EVLA method, especially in varicose veins of larger diameter and clinical class of 5 and 6. The occurrence of mild complications such as ecchymosis, edema and paraesthesia, is more common in the RFA method compared to EVLA. For EVLA, there is greater implementation difficulty, whereas the thermal profile is less smooth compared to RFA. This may be associated with the higher frequency of heat induced thrombosis for EVLA. There is a need for further research into both the differences between EVLA and RFA and their mechanisms of action to justify possible differences in efficacy and complications.
