Laser Ablation Therapy for Varicose Veins
Laser ablation is a minimally invasive procedure used to treat varicose veins, which are enlarged, twisted veins commonly found in the legs. This technique involves the use of laser energy delivered through a thin fiber inserted into the affected vein. The laser heats and seals the vein wall, causing it to collapse and eventually be absorbed by the body. Blood is naturally rerouted to healthier veins, improving circulation and reducing symptoms such as pain, swelling, and skin discoloration.

How does the treatment work?
Laser ablation is a minimally invasive treatment for varicose veins, which are enlarged veins caused by poor circulation. After numbing the skin with lidocaine, a small wire and catheter are inserted into the affected vein. The catheter delivers laser energy to the vein wall, causing it to heat, collapse, and seal shut. The treated vein is gradually absorbed by the body, while healthy veins take over blood flow.
What should I expect on the day of treatment?
On the day of your laser ablation treatment, you’ll arrive at the clinic or outpatient center, usually wearing loose, comfortable clothing. The procedure is typically performed under local anesthesia, so you’ll remain awake but relaxed. After cleaning the area, the doctor will numb the skin with lidocaine. A small incision will be made to insert a thin catheter into the targeted vein, often guided by ultrasound.
What should I do after treatment?
You should walk 30 minutes twice daily after treatment. This will alleviate discomfort and avoid the pooling of blood in the legs. It is normal to have aching in the treated veins. This response is well to walking, ice packs, and anti-inflammatory medications such as ibuprofen (Advil®, Motrin®) and naproxen (Aleve®).
Procedure:
Your physician will perform the ClosureFast procedure. Using ultrasound, your physician will position a catheter in the diseased vein through a small opening in the skin. The small catheter delivers heat to the vein wall, causing it to shrink and seal the vein. Once the diseased vein is closed, blood will reroute itself to other healthy veins. Following the procedure, your physician will apply a simple bandage over the insertion site, and may give you compression stockings to aid the healing process. Your physician may encourage you to walk, and to refrain from extended standing and strenuous activities for a period of time. The average patient typically resumes normal activities in a few days.
ClosureFast Radiofrequency Ablation Catheter
Provides thermal energy to the desired treatment site and relays temperature and other feedback to the RF generator. The ClosureFast™ catheter is a specialized medical device used during radiofrequency ablation (RFA) to treat varicose veins and chronic venous insufficiency. It’s one of the most widely used and trusted tools for vein treatment.
ClosureRFS Radiofrequency Ablation Stylet
Delivers bipolar RF energy to desired treatment site and relays temperature and other feedback to the RF generator.
ClosureRFG Radiofrequency Generator
Supplies and controls the RF energy delivered to the catheter.
ClosureFast™ Endovenous Radiofrequency (RFA) Ablation Catheter
Indications for Use: The ClosureFast™ endovenous radiofrequency ablation (RFA) catheter is intended for endovascular coagulation of blood vessels in patients with superficial vein reflux.
Contraindications: The ClosureFast catheter is contraindicated for use in patients with thrombus in the target vein segment.
Potential Adverse Effects of the Device on Health: The potential complications include, but are not limited to, the following: adjacent nerve injury, hematoma, pulmonary embolism, thrombosis, infection, phlebitis, skin burn or discoloration, and vessel perforation.
Important: Please reference the Instructions For Use (IFU) for a complete listing of indications, contraindications, warnings and precautions, adverse effects, and suggested procedure.
Frequently Asked Questions
What is Laser Ablation for Varicose Veins?
Endovenous Laser Ablation (EVLA or EVLT) is a minimally invasive procedure that uses laser energy to treat varicose veins and chronic venous insufficiency (CVI). It works by heating the inside of the diseased vein, causing it to close and be absorbed by the body.
How does EVLA work?
A laser fiber is inserted into the affected vein under ultrasound guidance. Once in place, the laser delivers targeted heat, damaging the vein wall and sealing it shut. Blood is naturally rerouted through healthier veins.
Is the procedure painful?
The procedure is done with local anesthesia, so you’ll feel little to no pain. You might feel slight pressure or a warming sensation during treatment.
What conditions does Laser Ablation treat?
- Varicose veins
- Chronic venous insufficiency (vein reflux)
- Symptoms like leg pain, swelling, heaviness, and skin changes
Is RFA painful?
The procedure is done under local anesthesia, and most patients experience minimal discomfort. You may feel slight pressure or warmth during the treatment.
Will the treated vein come back?
No, the treated vein is permanently closed, but new varicose veins can form over time. Lifestyle changes and periodic checkups can help prevent recurrence.
