Endovenous Laser Treatment - EVLT

EVLT Q&A | Ask a Doctor about EVLT

General Information

EVLT stands for Endovenous Laser Treatment. EVLT. A revolutionary new treatment used for significant varicose veins that previously were only effectively treated by ligation and removal.

EVLT is an outpatient procedure that involves ultrasound waves to identify the source of major varicose veins. The vein is collapsed using laser energy delivered from a thin laser fiber placed within the specific vein. The length of the vein is frozen with a local anesthetic to eliminate discomfort and protect surrounding tissues from excess laser heat. The procedure can take between 45 to 90 minutes to perform and patients have been known to return to work the same day.

There is a known success rate of 93 % with a recurrence rate of only 7 % after 2 years. An adverse effect profile shows to include minor bruising and minimal discomfort requiring minimal pain medication or none at all.

EVLT works by laser energy damaging he vein walls, shrinking and thus closing the damaged vein so blood may no longer flow through it.
The loss of a vein is generally not an issue- legs have many veins and after the treatment, blood in the faulty veins will be diverted to normal veins in order to make its way back to the heart. Removal of these affected areas of circulation may actually improve blood circulation blood in the treated area. Improvement in limb circulation will in effect cause improvement of the symptoms of fatigue and heaviness in the area.

With the inherent complications associated with any medical procedure, only minimal complications have been experienced with the EVLT procedure where there has been a small number of cases of numbness.

Traditionally, the faulty saphenous vein are treated by surgical ligation and stripping. This can involve at least two surgical incisions in order to tie off and pull out the faulty vein- this is usually performed under general anesthesia. EVLT has been shown to have a lower risk of complication; shorter recovery period, lower costs and no scarring associated with the procedure in comparison with surgery.

The common alternative therapies associated with this condition are ultrasound-guided sclerotherapy (also known as injection therapy) and radio frequency electrosurgery. Injection therapy or sclerotherapy for the saphenous vein appears to have a high recurrence rate frequently requiring additional re-treatment. Injection therapy is excellent for cosmetic treatment of any visible veins remaining after EVLT treatment. Radiofrequency electrosurgery has been known to be limiting in the range of patients it has been able to treat and the treatment time is noticeably longer than EVLT.

  • Is severe pain on inner ankle area normal after EVLT?
    (1 answer)
    Two (2) weeks after EVLT the only area that is problematic is my inner ankle area with a small opening taking a long time to heal. Comment made at time of surgery was that the vein was on the bone. Could this be the cause of the severe pain and swelling?
