This study aimed to evaluate the safety and clinical feasibility of tributary varicose vein ablation (VVA). The primary endpoint was the safety of VVA based on postoperative complications. Secondary endpoints included the target vessel occlusion rate and the reduction of subcutaneous induration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This multicenter prospective study included 311 limbs (240 patients) with saphenous-type varicose veins treated with VVA across four institutions. A 1470\u00a0nm diode laser and radial fiber were used with a standardized energy density of 25\u00a0J\/cm. Early complications were assessed at 1 week (n = 311). For the longitudinal analysis of induration and skin hyperpigmentation, 283 limbs that completed the 6-month follow-up were evaluated. Changes in categorical paired data were analyzed using McNemar\u2019s test. Factors associated with persistent pigmentation were analyzed using the unpaired t-test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The target vessel occlusion rate was 99.6% at 6 months. At 1 week, no instances of skin burns or infections were recorded. One case (0.3%) of pulmonary embolism occurred but resolved with anticoagulation. Subcutaneous induration was observed in 81.6% of limbs at 1 month (mean diameter: 4.92 \u00b1 2.34\u00a0mm) but significantly regressed by 6 months (26.1%, 2.50 \u00b1 1.66\u00a0mm;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; .001). Persistent minor nerve injury was rare (0.7% at 6 months).
