Endovenous Laser Treatment (EVLT) Applications
Endovenous Laser Treatment (EVLT) is a minimally invasive procedure used to treat varicose veins with high precision and long-term clinical success. Lumin Fiber’s radial laser fibers deliver uniform circumferential energy inside the vein, ensuring safe vein closure while reducing pain, bruising, and recovery time for patients.
What Is EVLT?

EVLT is a catheter-based laser treatment for superficial venous insufficiency, such as great saphenous vein (GSV) and small saphenous vein (SSV) reflux. Under ultrasound guidance, a laser fiber is introduced into the diseased vein. Controlled laser energy heats and collapses the vein wall, leading to permanent closure and redirection of blood flow to healthy veins.
Role of Radial Fibers in EVLT

Radial laser fibers are specifically designed for EVLT procedures. Unlike bare-tip fibers, radial fibers emit laser energy in a 360° ring pattern along the vein wall. This uniform energy distribution minimizes the risk of perforation, reduces carbonization, and provides more predictable vein closure with fewer side effects.
-
360° circumferential energy emission
-
Smooth, controlled pullback under tumescent anesthesia
-
Reduced postoperative bruising and discomfort
-
Compatible with 1470 nm and 1940 nm EVLT laser systems
Clinical Benefits for Varicose Vein Treatment

Using EVLT radial fibers for varicose vein treatment offers clear advantages over traditional surgery and some other thermal techniques. Patients benefit from a minimally invasive procedure with fast recovery and a low complication rate.
-
Outpatient procedure with local or tumescent anesthesia
-
Small puncture access instead of large incisions
-
High vein occlusion rate and durable long-term outcomes
-
Early return to normal activity
-
Improved cosmetic results
Indications for EVLT

EVLT is used to treat symptomatic venous insufficiency in the lower limbs. Typical indications include:
-
Great saphenous vein (GSV) insufficiency
-
Small saphenous vein (SSV) insufficiency
-
Incompetent perforator veins
-
Recurrent varicose veins after previous surgery or treatment
-
Associated varicosities caused by axial reflux

EVLT FAQ

1
Q1: What wavelength is commonly used with EVLT radial fibers?
A1: EVLT procedures are most often performed with 1470 nm or 1940 nm laser systems. These wavelengths are strongly absorbed by water in the tissue, allowing effective vein closure with reduced collateral damage.
2
Q2: Why choose radial fibers instead of bare-tip fibers for EVLT?
A2: Radial fibers distribute laser energy evenly around the vein wall, which supports controlled vein shrinkage and helps reduce the risk of vein perforation, postoperative pain, and bruising.
3
Q3: Can EVLT be performed as an outpatient procedure?
A3: Yes. EVLT is typically carried out under local or tumescent anesthesia in an outpatient or day-surgery setting. Most patients can walk immediately after the procedure and resume normal activities within a short time.
