''Can EVLT cause nerve damage?''

I am not sure if i can post this info here D, if not, please delete.
I've also post this in the topic 'Causes of parasthesia'

Info about Endovenous Laser http://en.wikipedia.org/wiki/Endovenous_laser_treatment

Read what DRs reply to a person who had Endovenous Laser procedure.
Can EVLT cause nerve damage?


I was impressed to read they all agreed to yes it can.

I need to mention that i have nothing against this procedure, i am not fully aware of it.
But, the positive reply, made such an impression to me.

Just some parts. He means nerves .
EVLT can cause thermal injury to nervers. Most commonly the injury is to small cutaneous sensory nerves that can cause skin numbness in a small area overlying the area of vein that was ablated. Injury to motor nerves is much less common, but can occur.


EVLT can be the cause of nerve damage, especially of the small sensation nerves. If this occurs, healing can be expected, however patience is required as nerve tissue is the slowest type of human tissue to heal. It can take up to a year for nerve damage to heal.
The sensory nerve is particularly close to the greater as well as the short saphenous veins at the ankle level. Thus, if the vein is treated this far down the leg, the incidence increases.
The fact that your discomfort is worsening may actually not be a negative factor. As sensory nerves regenerate, they can create uncomfortable sensations but may represent healing.

It is fine to post, but we probably need to clarify what EVLT is, since it is not the typical facial cosmetic device that we commonly discuss here. Alhtough this is useful and interesting information to have:

Endovenous laser treatment is a treatment for varicose veins in which an optical fiber is inserted into the vein to be treated, and laser light, normally in the infrared portion of the spectrum,[1] is shone into the interior of the vein. This causes the vein to contract, and the optical fiber is slowly withdrawn. Some minor complications can occur, including thrombophlebitis, pain, hematoma, edema and infection, which can lead to cellulitis.[2]

EVLT (Endovenous Laser Treatment) has the same meaning as ELT but is a trademark name owned by Diomed and used as the name for their 910nm laser treatment unit for ELT. The 810nm laser is the original laser fibre wavelength as pioneered by Dr Robert Min of New York USA. Subsequently, various other fibres with different wavelengths have become available. The varying wavelength each aim to maximise local damage to a component of the varicose vein or the blood contained in it while minimising damage to adjacent tissues.

During the procedure, a catheter bearing a laser fibre is inserted under ultrasound guidance into the great saphenous vein (GSV) or small saphenous vein (SSV) through a small puncture. The catheter is then advanced (also under ultrasound guidance) to the level of the groin or knee crease. Dilute local anesthesia is injected around and along the vein (perivascular infiltration) using ultrasound imaging to place the local anesthetic solution around the vein, mostly in a sub-facial location. This technique derives from the Tumescent Local Anesthesia ( TLA) method long used and proven safe and effective for some methods of Liposuction. The laser is activated whilst the catheter or laser fibre is slowly withdrawn, resulting in obliteration of the saphenous vein along its entire length. The treatment, which is performed without sedation, usually takes between 1 and 2 hours and the patient walks out under his or her own power. The leg is bandaged and/or placed in a stocking that the patient wears for up to 3 weeks afterwards. Foam sclerotherapy or ambulatory phlebectomy is often performed at the time of the procedure or within the first 1–2 weeks to treat branch varicose veins. However, some physicians do not perform these procedures at the time of the ELT because the varicose veins can improve on their own as a result of reduced reflux from the great saphenous vein.
