Why Choose Dual Wavelength Laser (980nm + 1470nm) for Varicose Veins (EVLT)?

Why Choose Dual Wavelength Laser (980nm + 1470nm) for Varicose Veins (EVLT)?

The TR-B laser system offers two distinct laser wavelengths: 980nm and 1470nm, each with unique advantages that make them highly effective for endovenous laser treatment (EVLT).

*980nm Laser: This wavelength exhibits balanced absorption in both water and blood, making it a powerful and versatile surgical tool. With an output power of up to 30 watts, it delivers robust energy ideal for efficient endovascular ablation.
*1470nm Laser: This wavelength has significantly higher absorption in water, resulting in more precise energy delivery and reduced thermal spread. This minimizes collateral thermal damage to surrounding tissues and adjacent venous structures, enhancing safety and patient comfort.

Given these complementary characteristics, combining both 980nm and 1470nm wavelengths is strongly recommended for optimal EVLT outcomes. The dual-wavelength approach leverages the high power and efficiency of the 980nm laser with the precision and safety of the 1470nm laser, offering a comprehensive solution for effective vein closure.

EVLT Procedure Overview

Endovenous Laser Treatment (EVLT) involves inserting a laser fiber directly into the affected varicose vein. The procedure is minimally invasive and typically performed on an outpatient basis. Here is a step-by-step outline:

*Administer local anesthesia to the treatment area and insert a needle into the target vein.
*Guide a guidewire through the needle and advance it along the length of the vein.
*Remove the needle, leaving the guidewire in place, and insert a catheter (thin plastic tube) over the wire into the saphenous vein.
*Advance a radial-emitting laser fiber through the catheter until the tip reaches the target treatment site—typically the junction at the groin crease.
*Perform tumescent anesthesia by injecting a local anesthetic solution around the vein using multiple needle punctures. This provides pain control and compresses the vein around the fiber, improving energy transfer and protecting surrounding tissues.
*Activate the laser and slowly retract the fiber in a controlled manner—typically 1 cm per second—over 20 to 30 minutes.
*As the fiber is withdrawn, laser energy heats the vein wall, causing uniform thermal damage that collapses and seals the vein shut. Blood is then naturally rerouted to healthy veins, eliminating reflux and reducing symptoms such as swelling and discomfort.
*Once the treatment is complete, remove the laser fiber and catheter. Apply a small dressing to the entry site.
*The entire procedure takes approximately 20 to 30 minutes per leg. For optimal results, smaller tributary varicose veins may require additional treatment with sclerotherapy.

EVLT is a safe, effective, and well-tolerated procedure that offers rapid recovery and excellent cosmetic outcomes.
