EVLT
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.
