Endoveneous Laser Ablation (ELA)
Endovenous Laser Ablation, or ELA, is a minimally invasive method for treating varicose veins in the legs. It is an alternative to surgical stripping of the greater saphenous vein (GSV). A diagnostic ultrasound exam is performed to determine if you are a candidate for ELA.
Common Endovenous Laser Ablation Questions
How is the treatment performed?
ELA is done in-office under local anesthesia. A small laser fiber is inserted, usually through a needle stick in the skin, into the damaged vein around the knee level. Under ultrasound guidance, the laser fiber is guided to the upper thigh. Pulses of laser light are delivered as the laser catheter is slowly pulled through the vein, causing the vein to collapse and seal shut.
What can I expect after my treatment?
Following the procedure, bandages are placed on the treated leg. Because the procedure is performed through a tiny skin nick, there will be no post-operative scarring. You may require subsequent injection sclerotherapy to completely eradicate all varicose veins after the laser procedure.
What should I wear?
Please wear loose-fitting pants, such as sweatpants because your legs will be wrapped with elastic bandages after the laser procedure.
What preparation is needed?
A mild anti-anxiety medication will be prescribed to use only if needed.
How long will the treatment take to perform? How many treatments are needed?
Please arrive 15 minutes prior to your exam time to verify registration information and prepare for the procedure. The procedure takes about 30 to 60 minutes per leg. Typically only one laser procedure per leg is necessary.
What are the side effects?
As with any medical procedure, some side effects may occur, such as temporary numbness, Deep Vein Thrombosis (DVT) and recurrence of the varicose vein. You may experience some bruising and possibly, leg cramping. Pain perception varies but is most often considered minimal.
Special Considerations
While there are no risks from the laser, as a precaution, you will be asked to wear a pair of special eyeglasses when the laser is in use.
Does insurance cover ELA?
Many insurances cover ELA for varicose veins causing pain, swelling or other symptoms. Check with your carrier or benefits administrator.
Will it work for me?
Results have been extremely favorable with success rates equal to the more painful and invasive approach of surgical ligation and stripping. ELA will normally treat the cause of most varicose veins but additional therapy, such as sclerotherapy, may be necessary.
What other options do I have?
- You may choose to forego treatment at this time. The varicose veins may progress and new ones may form. You should be reevaluated periodically to monitor your condition.
- If appropriate, your doctor may recommend you wear compression support hose to promote circulation.
- Surgical vein stripping may be an appropriate treatment for patients with larger varicose veins.
