How does endovenous laser therapy work?
Previously, treatment of painful, swollen varicose veins required a surgical procedure called vein stripping, where the vein was completely removed from the leg. More recently, endovenous laser therapy has been developed to treat chronic venous insufficiency by delivering laser energy through a small puncture in the leg to close the diseased vein.
With endovenous laser therapy, no surgery is required, and the entire procedure can be performed in less than one hour in your physician's office.
During the procedure, you are awake and your leg is anesthetized. A thin laser fiber is inserted into the great saphenous vein in your thigh. Your physician then will deliver laser energy through the fiber and into the vein, causing the vein to close.
Why is the laser fiber placed in the thigh, when the varicose veins are located below the knee?
Bulging varicose veins in the lower leg usually are caused by a faulty valve located higher in the leg that can't be seen at the surface. The endovenous laser therapy treats the source of the problem, which then causes the varicose vein in the lower leg to shrink and disappear.
Is the loss of the vein a problem?
No. Because there are many veins in the leg, the blood that would have flowed through the closed vein simply flows through other healthy veins after the laser therapy.
Is endovenous laser therapy painful?
Although individual responses vary, most people report little to no pain associated with endovenous laser therapy. Often the only sensation is felt during the delivery of anesthetic to the leg. After the procedure you may feel some tenderness, tingling, itching or tightness in the treated leg, which should disappear within a month.
How successful is endovenous laser therapy?
Clinical results have been published which document the success of endovenous laser treatment. Like any medical treatment, however, endovenous laser therapy has certain risks which your physician will explain to you as they apply to your individual case.
What should I do after the procedure?
After endovenous laser therapy, a gauze pad and tape will be placed over the puncture site and a compression stocking or compression bandage will be placed on your leg. You are encouraged to immediately walk following the procedure and resume normal activities. However, during the two weeks following your procedure you should avoid swimming, vigorous gym workouts, hot baths or excessive sun.
Your physician will provide customized instructions for you to observe following your endovenous laser therapy, including how long to wear a compression stocking. If you have any questions, ask your physician.
