Prospects of Endovenous Laser Ablation (EVLA) Standardization—Mid-Term Results of a Four-Zone Dosimetry Guiding Tool for 1940 nm Laser
This study presents mid-term results of endovenous laser ablation (EVLA) using a 1940 nm laser and radial fiber, supported by a four-zone dosimetry tool for standardization. The tool defines four anatomical zones for great saphenous veins (GSV) and two for small saphenous veins (SSV) with specific power levels. In 152 patients (185 procedures) with an 11.9-month mean follow-up, GSV occlusion rates were 98.9% at 1 month and 93.7% at 12 months. Complications were minimal, including laser-induced paraesthesia (2.2%) and endovenous heat-induced thrombosis (1.6%) at 1 month. The proposed tool standardizes EVLA dosimetry and shows promising results.
