Differences Between Sclerotherapy & Embolization

Define the Problem

• Varicose veins are large, raised, twisted blood vessels that appear blue or purple; spider veins are smaller and smooth. Varicose veins are common in the legs or face, but can also include hemorrhoids and varicocele, a type of vein abnormality in men that can cause infertility.
  
  

What Is Sclerotherapy?

• Sclerotherapy is a tried-and-true treatment for spider veins that has been performed in dermatologists' and plastic surgeons' offices since the 1930s. It involves the injection of a salt solution through a very fine needle into the dilated veins to stop blood flow to those capillaries.
  
  

What Is Embolization?

• Using x-ray imaging and a contrast material to see the blood vessel, a radiologist inserts a catheter through the skin into a blood vessel and inserts a substance called an embolic agent through the catheter and into the blood vessel or malformation, where it will stay to close the dilated blood vessel.
  
  

Recovery

• Compression bandages are applied and support hose may be recommended; to increase circulation, doctors recommend moderate exercise. Swelling, bruising and itching, as well as temporary dark spots, are common side effects.
  
  

Things to Watch for...

• Rarely, patients will suffer complications from sclerotherapy: ulceration, allergic reaction or pulmonary embolus.Call your doctor if you develop sores, and go to the nearest emergency room if you have swelling in the face and throat or have difficulty breathing.
