To demonstrate the 2-year outcomes after low energy endovenous laser ablation (EVLA) of incompetent saphenous veins with a 1470-nm diode laser

Between January 2011 and July 2013, 236 patients (335 limbs) were treated by EVLA using a 1470-nm laser with LEED of ≤80 J/cm for incompetent saphenous vein under ultrasound- and fluoroscopy-guidance. Patients were evaluated clinically and with duplex ultrasound at 1 week and 1, 3, 6 months, 1 year and 2 years after EVLA for the technical and clinical success and complication rate.

In the 335 limbs, the technical success rate was 100%. The GSV remained occluded in all of 229 limbs (100%) after 1 week, 202 of 203 limbs (99.5%) after 1 month, 157 of 158 limbs after 3 months (99.3%), all of 99 limbs after 6 months (100%), all of 41 limbs after 1 year, and all of 5 limbs after 2 years. The SSV remained occluded in all of 103 limbs (100%) after 1 week, all of 94 limbs (100%) after 1 month, 68 of 69 limbs (98.5%) after 3 months, 40 of 41 limbs(97.5%) after 6 months, and all of 14 limbs after 1 year (100%). Two GSVs and two SSVs were recanalized and they underwent repeated EVLA. No major complication occurred although bruising (21%), pain (15%) and paresthesia (4%) were observed.

In the 355 limbs, the technical success rate was 100%. The GSV remained occluded in all of 229 limbs (100%) after 1 week, 202 of 203 limbs (99.5%) after 1 month, 157 of 158 limbs after 3 months (99.3%), all of 99 limbs after 6 months (100%), all of 41 limbs after 1 year, and all of 5 limbs after 2 years. The SSV remained occluded in all of 103 limbs (100%) after 1 week, all of 94 limbs (100%) after 1 month, 68 of 69 limbs (98.5%) after 3 months, 40 of 41 limbs(97.5%) after 6 months, and all of 14 limbs after 1 year (100%). Two GSVs and two SSVs were recanalized and they underwent repeated EVLA. No major complication occurred although bruising (21%), pain (15%) and paresthesia (4%) were observed.

Low energy EVLA using 1470-nm laser with LEED of ≤80 J/cm is an effective, safe, and technically successful option for treating incompetent saphenous veins. Especially, complications like bruising, postprocedural pain, and paresthesia may occur less commonly.
