Clinical results of endovenous LASER ablation (EVLA) using low linear endovenous energy density (LEED) combined with high ligation for great saphenous varicose veins

Abstract

EVLA with a 1470-nm diode laser using low LEED combined with high ligation for the GSV has lower complication rates and higher occlusion rates of GSV.

Satisfactory result of great saphenous vein endovenous laser ablation until below the knee on active venous leg ulcer: a case series

“…27 Although a systematic review and meta-analysis by Malskat et al 28 showed that the commonly used EVLA parameters (wavelength, delivered energy, and outcome) did not affect the high success rate of the therapy (92%), the laser energy used in this study has a cut off of 50 J/cm. Mendes-Pinto et al 29 showed that closure rates at one-year follow-up were lower in a group of 1920-nm EVLA with LEED 17.8AE0.6 J/cm (87.5%) compared to the 1470-nm group with LEED 24.7AE0.8 J/cm (94.7%) whereas Park et al 25 performed EVLA using a 1470-nm laser with laser energy 6W LEED 30 J/cm on 267 limbs and obtained 84.5% completely obliterated GSV results in one month and 100% after six months. Utoh and Tsukamoto proposed EVLA with two-step ablation protocol in their trial that involved 90 limbs, using a 1470nm laser with energy 7W in ATK GSV (LEED 50 -70 J/cm) and 5W in BTK GSV (LEED 20-25 J/cm) with mean ablated GSV length of 50.4 cm.…”

“…12 The newer generation of EVLA with 1470-nm wavelength has more advantages with chromophore targeting only water in the endothelium compared to earlier laser generations with 940-nm and 980-nm wavelengths that targeted hemoglobin molecules. 25,26 EVLA with higher wavelength is related to lower energy levels and minimal side effects. 26 A study by Arslan et al 26 showed recanalization numbers were significantly lower (P=0.017) after 48 months of follow-up in a group of EVLA with 1470-nm radial-tip laser catheters using laser power LEED 45-120 J/cm (8.3%) compared to the group with 980-nm bare-tip laser catheter using laser power LEED 60-120 J/cm (15.9%).…”
