Effect of the wide-spread use of endovenous laser ablation on the treatment of varicose veins in Japan: a large-scale, single institute study

Effect of the wide-spread use of endovenous laser ablation on the treatment of varicose veins in Japan: a large-scale, single institute study

This study evaluates varicose vein treatments at a Japanese hospital, comparing stripping surgery and endovenous laser ablation (EVLA) with 980 nm and 1470 nm diode lasers. From October 2013 to December 2015, 289 patients were assessed. EVLA using the 1470 nm laser showed shorter operative times (22 minutes vs. 31 minutes for the 980 nm laser) and less pain. The EVLA group had a 99.6% occlusion rate after two years. EVLA with the 1470 nm laser is recommended for saphenous vein reflux, though traditional surgery is necessary for veins >20 mm or highly tortuous veins.

Twenty Years’ Experience with Endovenous Laser Ablation forVaricose Veins: A Critical Appraisalof the Original Procedure

Endovenous laser ablation (EVLA) for varicose veins is conducted in an ambulatory setting using tumescent local anesthesia (TLA). Technical advancements have reduced the need for multiple incisions, re-punctures, and minimized complications such as ecchymosis and technical failures. Using a 1470-nm diode laser with a radial fiber has enhanced patient satisfaction and lowered complication rates. The appropriate administration of TLA via infusion pump has decreased nerve injury risk, administration time, and procedural pain. High ligation and stripping are now rarely indicated. Over the past 20 years, EVLA has become an effective, cost-efficient, and safe procedure with high patient satisfaction.

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.
