The laser fiber was placed at the junction to the deep vein under duplex monitoring. Simultaneous phlebectomies were performed on all the patients. Regular follow up with clinical and duplex ultrasound examination (DUS) were carried out postoperatively at 1 month (1\u2009M), 6 months (6\u2009M), 12 months (12\u2009M), 24 months (24\u2009M), 36 months, and after that (\u226536\u2009M). The results were compared with three cohorts (total 616 EVLA procedures with 1470\u2009nm laser and radial fiber) from literature (criteria: &gt;100 procedures, follow\u2010up of \u22652 years).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The follow\u2010up rate was 100%, 91%, 73%, 48%, and 23% of the truncal veins at 1, 6, 12, 24, and \u226536\u2009M, respectively. In comparison to the literature using 1470, a lower average linear endovenous energy density (LEED) (53 vs. 77\u201382\u2009J\/cm) resulted in 100% (6\u2009M) and 96.5% (24\u2009M) occlusion rates, reduced local ecchymosis (2.2% vs. 3.2%\u201318.7%) and reduced average postoperative pain levels (1.3 vs. 2.18). Regarding adverse events, induration (1.1% vs. 1.8%), skin burns (0% vs. 0.45%), endovenous heat\u2010induced thrombus propagation (EHIT) in the deep veins (2.3% vs. 1.8%) and laser\u2010induced persistent paresthesia (2.2% vs. 0.5%\u20132.9%) were comparable. Recanalizations observed in this study (GSV 0, SSV 3) were asymptomatic and required no treatment. At \u226536\u2009M reflux in the accessory veins was observed in 5% versus 10.5% of patients. Reintervention was required in none (0% vs. 21%). At &gt;36\u2009M, short average stump lengths of 1\u2009cm (GSV) and 0.3\u2009cm (SSV) were observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>EVLA with 1940\u2009nm laser with radial emitting fiber is as safe and effective as 1470\u2009nm laser for the treatment of truncal vein insufficiency.
