EVLT Laser Overview
Endovenous Laser Treatment (EVLT) is a minimally invasive procedure used to treat varicose veins using laser energy.
Why Varicose Veins Occur
Weak vein walls
Poor blood circulation
Prolonged standing or sitting
Blood pooling in lower limbs
1940nm Laser Advantage
Highest absorption in water
More efficient than 1470nm and 980nm
Requires lower power (4–6W)
Safer and more precise
Procedure Steps
- Ultrasound marking
- Local anesthesia
- Fiber insertion into vein
- Laser energy delivery
- Vein closure
- Compression applied
- Immediate recovery
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.
Key Clinical Advantages
Virtually Bruise-Free
Since the primary chromophore is water rather than hemoglobin, vessel rupture and erythrocyte extravasation are minimized, resulting in little to no post-treatment bruising.
Lower Risk of Hyperpigmentation
Energy remains confined within the vessel wall, reducing thermal diffusion into adjacent tissues and significantly lowering the incidence of post-inflammatory hyperpigmentation.
Concurrent Skin Tightening
Localized thermal stimulation promotes collagen denaturation and remodeling in the dermis, providing a secondary benefit of skin tightening in the treated area.
Enhanced Patient Comfort
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.
2. What conditions does EVLT treat?
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
