Abstract
Objective: To evaluate outcomes of 1470-nm endovenous laser ablation (EVLA) and associations with energy density (LEED) and anatomy. Methods: We followed 91 patients at baseline, 24 hours, 1 month, and 6 months, using patients as the unit of analysis. Results: Mean LEED was 61.3 ± 9.8 J/cm. Complete occlusion was 100% at 1 month and 97.8% at 6 months; VCSS and clinical CEAP class improved (p < 0.001). LEED correlated inversely with proximal occlusion stump-to-deep venous junction distance (r -0.51 to -0.53; p < 0.001). Each 10-J/cm LEED increase was associated with 2.75-fold higher odds of paresthesia at 1 month. Higher LEED and shorter vein-to-skin distance were associated with skin discoloration. Conclusion: EVLA achieved high occlusion rates, while LEED and anatomy were associated with local postprocedural findings.
