The principle of EVLT
EVLT, or Endovenous Laser Treatment, is a minimally invasive procedure that utilizes laser energy to treat varicose veins by delivering targeted heat directly into the vein, causing it to collapse and eventually be reabsorbed by the body, thereby eliminating the affected vein and improving blood flow.

Clinical Applications of EVLT Laser Treatment
In the EVLT procedure, the surgeon utilizes ultrasound imaging to locate the target vein. The veins suitable for treatment include the primary venous trunks in the legs, such as the Great Saphenous Vein (GSV), the Small Saphenous Vein (SSV), and their significant tributaries, like the Anterior Accessory Saphenous Veins (AASV).






The laser treatment for Endovenous Laser Therapy (EVLT) works by inserting a laser fiber into the targeted vein under ultrasound guidance. The laser emits energy that heats and closes the vein, causing it to collapse and be reabsorbed by the body. This process effectively eliminates the faulty vein, rerouting blood flow to healthier veins.
Advantages of Laser in EVLT
-
Precision:
The laser allows for precise targeting of the vein, minimizing damage to surrounding tissues.
-
Minimally Invasive:
The procedure requires only a small incision, reducing the risk of infection and promoting quicker healing.
-
Effectiveness:
Laser treatment provides high success rates in vein closure and symptom relief.
-
Reduced Pain:
The laser's precision and the minimally invasive nature of the procedure result in less postoperative pain compared to traditional vein stripping.
Benefits for Patients
-
Short Recovery Time:
Patients typically experience a quicker recovery and can return to normal activities sooner. -
Low Complication Rate:
The minimally invasive approach reduces the risk of complications such as infection and scarring. -
Outpatient Procedure:
EVLT can usually be performed on an outpatient basis, eliminating the need for hospitalization. -
Improved Aesthetics:
The treatment results in less bruising and scarring, leading to better cosmetic outcomes for patients.
The most popular wavelength option ----- 1470nm
The 1470nm laser wavelength is highly absorbed by water, making it particularly effective for endovenous procedures. This wavelength provides excellent precision in targeting the vein walls, ensuring efficient vein closure with minimal thermal damage to surrounding tissues.

Top choice for EVLT in future clinical utilization ---- 1940nm
On the basis of 1470nm, the 1940nm wavelength represents a higher advancement in laser technology, offering improved efficacy and safety for EVLT procedures.
-
Enhanced Water Absorption:
Requires lower power, ensuring precise vein closure with reduced tissue damage.
-
Reduced Energy Density :
Less than 50 J/cm(LEED), minimizing thermal damage to surrounding tissues.
-
Less Postoperative Pain:
Promotes quicker recovery and improved patient comfort.
-
Minimal Risk of Burns and Scarring:
Enhances cosmetic outcomes by avoiding visible incisions.
-
High Success Rate with Low Complications:
Balances efficacy with safety for optimal treatment outcomes in varicose vein management.
