Fotona’s EndoVenous Laser Ablation (EVLA) treatment works by targeting Nd:YAG laser energy to the interior of a vein, causing the vein wall to shrink and seal shut. The healthy veins that surround the closed vein can then restore the normal flow of blood to the treated area.
EVLA is principally effective on large truncal veins in the legs. Laser energy is delivered to the desired location inside the vein through an optical fiber and catheter. Laser treatments are less invasive than traditional surgical methods of varicose vein removal, have a lower complication rate, and are well tolerated by patients. Recovery time is short and the treatment produces good cosmetic results.
Fotona’s QCW Nd:YAG laser has a particular affinity for absorption in hemoglobin, making it an ideal choice for endovenous laser treatments. Its high performance, selectivity and precision (limiting thermal effects to the target tissue), allow for minimal discomfort, exceptional success rates and shortened recovery times.
Endovenous Laser Ablation treatments can be best performed with the following Fotona laser systems:
All Fotona Nd:YAG lasers are equipped with VSP (Variable Square Pulse) technology to provide the widest range of selectable pulses and greater procedural safety. Compared to conventional Nd:YAG technologies, Fotona’s proprietary VSP pulses create virtually instantaneous temperature increases that are limited to the targeted structures only. Square pulses of laser light reach peak powers faster, remain constant and return to zero immediately. This contributes to higher long-term success rates and shorter recovery times.
