EVLT Endovenous Laser Therapy Vascular Vein Surgery 1470nm Two
EVLT Surgery Vascular Vein Surgery 1470nm Laser
EVLA is a new method of treating varicose veins without surgery.
Instead of tying and removing the abnormal veins,they are heated by
a laser. The heat kills the walls of the veins and the body then
naturally absorbs the dead tissue and the abnormal veins are
destroyed. It can be carried out in a simple treatment room rather
than an operating theatre.
Advantages for 1470nm diode laser for vascular veins:
1. The advanced laser technology for red blood
veins/vascular/spider veins removal in contrast with high frequency
in the market
2. 1-15W adjustable energy to satisfy different requirements
3.Three modes: CW Pulse ,Pulse ,and Single for optional
4.Short time operation, no injury, no bleeding, no burning, redness
5.The obvious effectiveness: Only one or two treatments are
What does Endovenous Laser Ablation procedure involve?
An ultrasound scan is performed and the veins to be treated are
marked with a pen. You lie on a couch and your leg is cleaned and
covered with drapes. Depending on which veins are to be treated,
you may be on your back or your front. All these steps are guided
by ultrasound scanning.
Endovenous means inside the vein, so the next thing the doctor has
to do is to get inside your vein. A small amount of local
anaesthetic is injected into the skin over the vein and a needle
inserted into it. A wire is passed through the needle and up the
vein. The needle is removed and a catheter (thin plastic tubing) is
passed over the wire, up the vein and the wire removed.
A laser fibre is passed up the catheter so its tip lies at the
highest point to be heated (usually your groin crease). A large
quantity of local anaesthetic solution is then injected around the
vein through multiple tiny needle pricks. All staff and the patient
put on laser safety specs as a precaution. The laser is then fired
up and pulled down the vein over about 5 minutes. You will hear a
warning buzzer ringing and may smell or taste burning but won’t
feel any pain. If you're having both legs treated the process is
repeated on the other leg. The laser and catheter are removed and
the needle puncture covered with a small dressing.
The treatment takes about 20-30 minutes per leg. You may also have
some foam sclerotherapy or some avulsions undertaken and a
compression stocking is then put on.
The 1470nm laser wavelength of CHERYLAS is effectively used in the
treatment of the varicose veins, 1470nm wavelength is
preferentially absorbed by water 40 times more than a 980-nm
wavelength, the 1470nm laser will minimize any post-operative pain
and bruising and the patients will recovery quickly and back to
daily work in short time.
