Endoluminal laser delivery mode and wavelength effects on varicose veins in an Ex vivo model

Endovenous laser ablation (EVLA) has been shown to be effective for the elimination of saphenous veins and associated reflux. Mechanism is known to be heat related, but precise way in which heat causes vein ablation is not completely known. This study aimed to determine the effects of various endovenous laser wavelengths and delivery modes on ex vivo human vein both macroscopically and microscopically. We also evaluated whether protected‐tip fibers, consisting of prototype silica fibers with a metal tube over the distal end, reduced vein wall perforations compared with non‐protected‐tip fibers.
