Laser Surgery for Varicose Veins

How Does Laser Surgery Work?


Updated June 11, 2014

Laser surgery works by sending very strong bursts of light onto the vein that makes the vein slowly fade and disappear. Lasers are very direct and accurate, and only damage the area being treated. All skin types and colors can be safely treated with lasers. The American Academy of Dermatology believes that the new laser technology is more effective with fewer side effects. Laser surgery is more comfortable for patients because there are no needles or incisions. When the laser hits the skin, the patient only feels a small pinch, and the skin is soothed by cooling both before and after the laser is applied. There may be some redness or swelling of the skin right after the treatment, but this disappears within a few days. The skin also may be discolored, but this will disappear within one to two weeks. Treatments last 15 to 20 minutes, and depending on the severity of the veins, two to five treatments are generally needed to remove varicose veins in the legs. Patients can return to normal activity right after treatment.

There are several types of lasers that can be used to treat varicose veins and spider veins on the legs and face. Although your doctor will decide which type is best to treat your condition, some of the lasers used to treat veins include yellow light lasers, green light lasers, and other intense pulsed light systems. Again, health insurance coverage varies. If the treatment is done for cosmetic reasons only, it may not be covered.

Closure Technique

The U.S. Food and Drug Administration (FDA) in March 1999 approved this new procedure for use in the United States. Although it is not as widely used as sclerotherapy, some doctors feel it may become the standard for treating varicose veins. It is not very invasive and can be done in a doctor's office. This method involves placing a special catheter or a very small tube into the vein. Once inside, the catheter sends radiofrequency energy to cause the vein wall to shrink and seal shut. Healthier veins surrounding the closed vein can then restore the normal flow of blood. As this happens, symptoms from the varicose vein decrease. The only side effect is slight bruising.

Surgery is used mostly to treat very large varicose veins.

Available surgical options include:

Surgical Ligation and Stripping

With this treatment, the veins are tied shut and completely removed from the leg. Removing the veins will not affect the circulation of blood in the leg because veins deeper in the leg take care of the larger volumes of blood. The varicose veins mostly removed through surgery are superficial or surface veins, and collect blood only from the skin. This surgery requires either local or general anesthesia and must be done in an operating room on an outpatient basis.

Serious side effects or complications with this surgery are uncommon. However, with general anesthesia, there always is a risk of cardiac and respiratory complications. Similar to the risks of sclerotherapy, bleeding and congestion of blood can be a problem, but the collected blood usually settles on its own and does not require any further treating. Wound infection, inflammation, swelling and redness also can occur. This surgery also can leave permanent scars. A very common complication is the damage of nerve tissue around the treated vein. Small sensory nerve branches are difficult to avoid when veins are removed. This damage can cause numbness in small areas of skin, burning, or a change in sensation around the surgical scar. The most serious, but rare, complication of surgery is the creation of a deep vein blood clot that may travel to the lungs and heart. To be safe, many surgeons give injections of heparin, a drug that reduces blood coagulation, for one to two days before the surgery. However, heparin also can increase the normal amount of bleeding and bruising after the operation.

Ambulatory Phlebectomy

With this surgery, a special light source marks the location of the vein. Tiny incisions are made in the vein, and then with surgical hooks, the vein is pulled out of the leg. This surgery requires local or regional anesthesia. The vein usually is removed in one treatment. Side effects and complications are similar to those of ligation and stripping. The most common side effect is slight bruising. Compared to traditional surgery, ambulatory phlebectomy allows the removal of very large varicose veins while leaving only very small scars. Patients can return to normal activity the day after treatment.
