The term "LASER" stands for Light Amplification by Stimulated Emission of Radiation.
In this technique heat energy is used to close the varicose veins. The heat energy
is generated by a special machine, and delivered into the blood vessels by special
“diode laser” fibers.
This Endovenous Laser method of treatment of varicose veins avoids surgical cuts
and scars, and is performed under local anesthesia. Most types of varicose veins
can be treated using this technique.
The Laser fiber into the veins
The Bioletic Laser Machine
When the laser energy is delivered into the vein, the heat energy is selectively
absorbed by the water content of the blood in the vein, and causes damage to the
inner lining (intima) of the vein, causing the vein to collapse and close. Later
on the vein permanently closes due to a process of fibrosis, and the residual tissue
is removed by the body mechanisms, so that after a period of time, no vein is seen
The Laser Technique of treatment of Varicose Veins:
1. The case of Varicose veins to be treated is first evaluated by a sonography test,
called a Doppler ultrasound test.
2. The course of the vein is then marked onto the skin.
3. Local anesthesia is infiltrated at the site of needle entry into the vein. The
vein is entered with a needle, under ultrasound guidance, similar to the procedure
of drawing blood from a vein during a blood test.
4. Through the needle a guide wire is threaded into the vein, and over it a small
plastic tube called a catheter. Through this hollow catheter, the thin laser fibre
is advanced into the vein; this entire procedure is performed under guidance of
5. The position of the Laser fiber in the vein is confirmed by the red light at
the tip of the laser fiber which shines through the skin.
6. Now, generous amounts of dilute anesthetic solution called Tumescent Anasthesia
is injected all along the course of the vein. This is done via very thin needles,
and under ultrasound guidance. This anesthetic solution is injected all around the
vein, so that the vein collapses over the laser fiber within. Also, the layer of
anesthetic solution around the vein prevents heat energy from travelling outside
the vein to surrounding structures.
7. The laser fiber is now connected to the laser machine, and laser energy is delivered
into the vein. This causes an immediate closure of the vein, which can be seen on
the ultrasound image. The laser fiber is gradually withdrawn so as to close the
complete length of the vein.
8. The end result can be seen almost immediately, in the form of collapsed veins.
9. At the end of the procedure the catheter is removed from the vein, leaving only
a small puncture mark. This heals within a few days.
10. At the end of the procedure, a compression bandage or stocking is applied over
the treated leg, and the patient is made to walk for about 15 to 20 minutes. Most
patients can resume their normal activities and driving the next day.
