EVLT - Risks,
Complications, Alternatives
The advent
of laser treatments has opened the door to more variation in terms of treating
varicose veins. At one time it was
necessary to have surgery done to rid the legs of the unsightly, gnarled,
bulbous veins. Or, a person wore
compression stockings to make life more bearable. While these methods are still in use, there
are more advanced and less restrictive ways of dealing with varicose veins with
the use of laser power.
EVLT Procedure
Endovenous
laser treatment requires no incisions and is performed with a laser fiber and ultrasound
visualization of the vein. The
administration of a local anesthesia to numb the area where the needle
penetrates is given and the area above the knee where the vein in question is
located is cleaned with an antiseptic ointment or cleanser. A needle is placed in the vein and a small
laser probe is inserted. The probe is
discerned and its position verified on ultrasound. Once its position is confirmed, the probe is
heated slowly with low energy. The vein
walls become damaged and begin to shrink, eventually closing the vein,
prohibiting the flow of blood. Once the
vein is burned the probe is taken out and a dressing applied. A compression bandage is worn for about a
week and the entire process takes about one hour in total.
Recovery
Recovery is
very fast and relief from the discomfort of the veins is almost immediate. Since there is no incision, there are no
scars and there is minimal post operative pain.
A minor soreness and bruising may occur which can be treated with OTC
pain medication. Patients are encouraged
to walk and get back to normal activities right after the procedure and to
follow-up with the practitioner in a week or two.
Complications
There are
potential complications which may arise; however, with EVLT, these are very
rare. The thigh area may become mildly
numb and there might be a pulling sensation for about a week after the
procedure. A very mild case of phlebitis
- redness and tenderness of the skin - tends to be common. This condition is normally gone in three to
seven days. Very rarely there is a case
of deep venous thrombosis. The best way
to avoid this situation is to wear compression stockings or bandages and to
walk immediately after the procedure.
Mild bruising is quite common, but also resolves in a week. On rare occasions the procedure fails. This is usual due to the inability to insert
the probe into the vein or the inability of the laser to destroy the vein. Most frequently, these cases involve
inexperience on the part of the physician with the procedure.
Alternatives
Alternatively,
for large veins there is surgery, which requires the use of anesthesia,
incisions and ultimately scars. Recovery
time is much longer and it's more painful as well. Sclerotherapy is not used to treat large
veins. Ultrasound-guided mini-sclerotherapy
and radio frequency electro surgery are other options which are closer in
nature to EVLT.
