Endovenous Laser Treatment (EVLT) is a minimally invasive procedure used to treat varicose veins. Varicose veins occur when venous valves weaken, leading to blood pooling in the lower limbs. This results in visible, enlarged, and twisted veins, often accompanied by symptoms such as swelling, fatigue, skin discoloration, and, in advanced cases, venous ulcers.
The 1940nm wavelength demonstrates the highest absorption in water compared to earlier laser wavelengths (808nm, 980nm, and 1470nm). Since venous walls contain a high proportion of water, this allows for more efficient and targeted energy delivery.
Clinical studies show that:
1940nm has significantly higher absorption than 1470nm
It is several times more efficient than 980nm
Requires lower operating power (4–6W), improving safety and precision
EVLT is typically performed in an outpatient setting:
Ultrasound is used to identify and mark the treatment area
Local anesthesia is applied
A small incision is made, and a laser fiber is inserted into the vein
Laser energy is delivered while withdrawing the fiber, closing the vein
No sutures are required; compression stockings are applied
Patients can return to normal activities immediately
Mechanism of Action
Precision Energy Absorption
The 1940nm laser is selectively absorbed by water in the vein wall, ensuring accurate targeting.
Direct Vein Closure
Thermal energy causes collagen contraction and endothelial damage, sealing the vein.
Natural Absorption
The treated vein gradually fibroses and is naturally absorbed by the body over time.
Since the primary chromophore is water rather than hemoglobin, vessel rupture and erythrocyte extravasation are minimized, resulting in little to no post-treatment bruising.
Energy remains confined within the vessel wall, reducing thermal diffusion into adjacent tissues and significantly lowering the incidence of post-inflammatory hyperpigmentation.
Localized thermal stimulation promotes collagen denaturation and remodeling in the dermis, providing a secondary benefit of skin tightening in the treated area.
The selective and localized action reduces stimulation of perivascular nerves, improving comfort during the procedure and shortening recovery time.

1. What is EVLT?Endovenous Laser Treatment (EVLT) is a minimally invasive laser procedure in which a thin optical fiber is introduced into the diseased vein under ultrasound guidance. Laser energy is delivered along the vein, causing controlled thermal injury to the vessel wall. This leads to vein closure and subsequent absorption by the body, effectively treating varicose veins and other venous disorders.
EVLT is commonly used to treat:
Lower extremity varicose veins
Telangiectasias (spider veins)
Venous reflux insufficiency
Chronic venous insufficiency (CVI)
Selected hemangiomas and abnormally dilated vascular lesions
