Treatment of Varicose Veins of the Leg


This procedure involves taking out or causing damage to varicose veins just under the skin.

Dirfferent approaches may involve:

  • Sclerotherapy—injects the varicose veins with a chemical to shrink them
  • Radiofrequency ablation—collapses and seals varicose veins using radiofrequency energy
  • Adhesive sealing—seals the affected veins that are close to the skin using an adhesive
  • Vein stripping
  • Phlebectomy

Reasons for Procedure

Veins have one-way valves to keep blood moving toward the heart. Damage to the valves can cause blood to pool in the veins. This makes them larger. It also makes the veins just under the skin easier to see. Clots can form in the pooled blood. This can cause burning, aching, or throbbing.

The skin can also turn dark purple or brown because. In some cases, the discolored skin may break down and cause ulcers.

These procedures can be cosmetic or for health reasons.

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review possible problems such as:

  • Return of varicose veins
  • Bleeding
  • Infection
  • Skin discoloration at the surgical site
  • Deep vein thrombosis

Smoking may raise the chances of having these problems.

What to Expect

Prior to Procedure

You may have a:

  • Physical exam—includes carefully checking the veins
  • Doppler ultrasound

Leading up to the procedure:

  • Talk to your doctor about your medicines. You may be asked to stop taking some medicines up to 1 week in advance.
  • You may need to wear special support stockings.
  • If you have an ulcer, wear Unna boots. This is a type of cast that helps with healing.


The anesthesia depends on the type of procedure that you are having. It may be:

  • General —blocks pain and keeps you asleep
  • Epidural —numbs the area from the chest down to the legs

Description of the Procedure


A chemical will be injected into each of the damaged veins. It will scar the vein so that it can’t move blood.

Adhesive Sealing

A catheter is inserted into the damaged vein. An ultrasound is used to view the placement of the catheter. An adhesive is injected into the catheter to seal the vein.

Radiofrequency or Laser Ablation

This is done on one of the largest superficial vein. The vein will be viewed using an ultrasound. Then, the vein will be punctured near the knee. A catheter will be threaded up to the groin. The space between the vein and the skin will be filled with a special solution. This solution will provide local anesthesia. The catheter will then be attached to a radiofrequency generator or a laser. Heat or light energy will seal the vein closed so that there is no longer any backflow of blood.

Vein Stripping

The veins will be removed by threading a long wire into them. Each vein will be tied to this wire and then stripped out. This will leave the smaller side branches broken off and in place. This procedure is usually not used on the largest vein.


This surgery is used to remove larger veins that cannot be injected. Many small incisions will be made to access each varicose vein. The vein will either be tied off or removed.

After the Procedure

If vein stripping is done, you will have many loose vein ends in your leg. Your leg will be tightly wrapped. This is to prevent blood from leaking out of the veins.

How Long Will It Take?

  • Sclerotherapy—short office visit
  • Adhesive sealing—short office visit
  • Radiofrequency or laser ablation—1 hour
  • Vein stripping—1-1½ hours
  • Phlebectomy—2-4 hours

Will It Hurt?

Anesthesia will prevent pain during surgery. Medicines will help ease pain after.

Post-procedure Care

You may need to have an ultrasound in the future.

Call Your Doctor

Call your doctor if any of these occur:

  • Fever or chills
  • Redness, swelling, pain, excess bleeding, or pus from the wound
  • Pain that you cannot control with the medicines you were given
  • Pain, burning, urgency or frequency of urination, or blood in the urine
  • Coughing, breathing problems, or chest pain
  • Leg swelling

If you think you have an emergency, call for emergency medical services right away.
