Phlebological Laser for Varicose Veins – EVLT

Endovenous Laser Ablation Treatment, also known as endovenous laser therapy, is a safe, proven medical procedure that not only treats the symptoms of varicose veins but also treats the underlying condition that causes them.

Endovenous means inside the vein, a small amount of local anesthetic is injected into the skin over the vein and a needle is inserted into it. A wire is passed through the needle and up the vein. The needle is removed and a catheter is passed over the wire, up the vein and the wire is removed. A laser fiber is passed up the catheter so its tip lies at the highest point to be heated (usually your groin crease). A large quantity of local anesthetic solution is then injected around the vein through multiple tiny needle pricks. The laser is then fired up and pulled down the vein to heat the lining within the vein, damaging it and causing it to collapse, shrink, and eventually disappear.

Absorption Coefficient of 980nm 1470nm 1940nm EVLT laser

Multiple Wavelengths Can Be Chosen for EVLT Treatment

The Dimed 1470nm lasers are highly effective in treating varicose veins due to their wavelength preference for water absorption, which is 40 times greater than the 980nm wavelength. Utilizing a radial fiber, it offers an optimal solution for the endovenous removal of saphenous veins, establishing itself as the gold standard in this surgical approach. its application minimizes post-operative pain and bruising, leading to accelerated patient recovery.

The Dimed 1940nm varicose laser achieves efficacy comparable to 1470nm lasers but with significantly fewer risks and side effects, including reduced chances of paresthesia, increased bruising, and patient discomfort. The use of a 1940nm wavelength allows for effective surgery with smaller power requirements, enhancing safety and predictability for doctors while facilitating faster and more comfortable patient recovery.

Clinical Applications of EVLT Laser Treatment

During the EVLT procedure, the surgeon uses ultrasound to find the vein to be treated. The veins that can be treated are the main venous trunks of the legs:

  • Great Saphenous Vein (GSV)
  • Small Saphenous Vein (SSV)
  • Their major tributaries such as the Anterior Accessory Saphenous Veins (AASV)
    difference between 1470nm and 1940nm endovenous laser

Advantages of Endovenous Laser for Varicose Veins Treatment:

  • Minimally invasive, less bleeding.
  • Curative effect: operation under direct vision, the main branch can close tortuous vein clumps
  • Surgical operation is simple, treatment time is greatly shortened, and reduce patient’s pain
  • Patients with mild disease can be treated in the outpatient service.
  • Postoperative secondary infection, less pain, quick recovery.
  • Beautiful appearance, almost no scar after surgery.
