Background:
The aim of the study is to compare the current two endovenous thermal ablation methods by examining the effects on the visual analog scale (VAS) and the short form-36® quality of life index.
Methods:
Ninety-six patients who underwent unilateral endovenous thermal ablation of great saphenous vein were included. ClosureFast™ catheters were used in the RFA group and 1470 nm radial fiber laser catheters were used in the EVLA group.
Results:
The RFA group consisted of 41 patients and the EVLA group consisted of 55 patients. The preoperative baseline characteristics of both groups were similar. On the day of operation, VAS values were 2.8 ± 1.1 in the RFA group and 3.6 ± 1.8 in the EVLA group (p = 0.02). Comparisons of short form-36 parameters in both groups showed them to be similar except the pain detected at postoperative 1st week (48.1 ± 5.4 for RFA, 44.9 ± 7.6 for EVLA, p = 0.04).
Conclusion:
Results in postprocedural quality of life were found to be similar in both of the techniques. However, in terms of postoperative pain, radiofrequency ablation is still superior to the 1470 nm radial fiber laser catheters.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
