If you have large varicose veins, surgery may be the best choice. However, it will not prevent new varicose veins from forming. Surgery is most often performed in a hospital or surgery center on an outpatient basis.
Your surgery will be tailored to your needs. Varicose veins may be tied off (ligation), destroyed, or removed. Blood will then flow through the healthy veins. One or more of the following techniques may be used:
In more severe cases, the surgeon may tie off and remove veins by making smaller cuts in the skin. Smaller branching veins may also be tied off or removed.
A special hook is used to gently take out a varicose vein through tiny incisions. Microphlebectomy may be done in your healthcare provider’s office.
Your healthcare provider will inject the varicose vein with a special chemical that will quickly close the vein from the inside. This is particularly useful for smaller veins.
All or part of the vein may be removed with a stripping instrument.
A tiny cut in the skin is made near the varicose vein. A small tube called a catheter is inserted into the vein. Energy or heat released from the catheter tip will make the vein walls collapse and stick together, stopping all blood flow through the vein.
Your healthcare provider will talk with you about the risks of surgery. These include:
Bleeding or swelling
A sense of numbness, burning, or tingling in areas near the procedure
Edema or swelling in the legs
Clots in the deep veins that may travel to the lungs
