Ultrasound Guided Foam Sclerotherapy (UGFS)

The treatment of venous disease has undergone a revolutionary transformation with addition of duplex ultrasound. Ultrasound Guided Foam Sclerotherapy is a highly specialized procedure for treating deeper varicose veins that are not visible from the surface of the skin. This procedure is quick, safe, and effective.


  • Quick, in-office procedure
  • No anesthetic required
  • Little to no downtime
  • Can resume normal daily activity
  • Faster recovery compared to surgery

How It Works

A sclerosant solution is mixed with air to create a foam consistency, called microfoam. Using a small needle, under ultrasound guidance, the foam is injection into the abnormal vein. The foam pushes the blood out of the way and allows the foam to touch the lining of the vessel. This triggers an inflammatory response causing the vein to close. Over time, the veins dissolve and disappear as the body gradually absorbs them.

What To Expect

This non-surgical treatment option is an in-office procedure that takes approximately 20 minutes. Most patients experience mild discomfort as expected with a small needle. Immediately after, we will apply a class II, 30 – 40 mmHg medical compression stocking to be worn for 1 week. Before leaving we will schedule a follow-up ultrasound appointment for one week post treatment to ensure success.


UGFS shows an 85% success rate. Re-treatment may be required depending on size of vein being treated, anatomical positioning of vein, compression fit and compliance. Once the main source of reflux has been successfully treated, you may require many more sessions of sclerotherapy (without ultrasound). Upon successful vein closure of all affected veins, patients can expect relief of symptoms caused by venous disease.


  • The first day requires periods of walking and elevating the treated leg.
  • Can resume normal daily activity with the avoidance of heavy leg exercise.
  • Mild discomfort that may last for weeks after treatment. Should resolve with anti- inflammatory or mild analgesic.
  • Bruising that can last 2 – 3 weeks.
  • Lumpiness along the path of the treated vein due to hardening of the vessel.


You should not have any air travel planned for at least 3 weeks after your treatment. You are encouraged to improve lifestyle factors to aid in the prevention of the progression of venous disease.

Lifestyle Improvements

  • Wear 20 mmHg – 30 mmHg compression stockings
  • Exercise regularly
  • Drink lots of water
  • Eat well and maintain a healthy weight
  • Leg elevation
