Vein Treatments

Ultrasound Guided Sclerotherapy (UGS)

UGS is a world-wide recognized treatment.  UGS involves injection of a chemical solution into the vein in order to irritate the inside of the vein wall.

The vein turns from soft, to solid and fibrous. The body gradually absorbs the fibrous vein over the next few weeks or months.  

A number of injections will usually be required and more than one treatment may be required.

The chemical solution is called a sclerosant and the Vein and Skin Clinic’s Phlebologists use either Sodium Tetradecyl Sulphate (STS) (Sclerovein), or Polidocanol (Aethoxysclerol) (Fibrovein). Both have been used safely and effectively world-wide for more than 50 years. 

UGS has enjoyed greater popularity and a dramatically improved success rate, since the introduction of foam sclerosants. The Vein and Skin Clinic’s Phlebologists are well experienced with the use of foam sclerosants, having performed several thousand successful procedures over the past decade.

Efficient and effective, Ultrasound Guided Sclerotherapy (UGS) provides a modern, non-invasive alternative to traditional surgery in the management of varicose veins. It is often more suitable for post surgical recurrence and for some small varicose veins.

The Vein and Skin Clinic have performed several thousand successful UGS procedures over the past two decades.

UGS Procedure

Modern ultrasound machines allow accurate visualization and mapping of all leg veins (deep and superficial). 

At the Vein and Skin Clinic, an experienced sonographer assists the Phlebologist (vein expert) to insert a fine needle into the varicose vein. The progress and effect of the foam sclerosant can be observed. 

Usually several needle insertions are required. Treatment sessions are 30-60 minutes.  Pain is minimal. Further treatments may be needed. Grade 2 compression stockings are worn for two or more weeks. Work and normal activities are resumed immediately.

UGS is a walk in, walk out procedure with low incidence of risk. The Vein and Skin Clinic provides a comprehensive hand-out that includes a list of possible risks and side effects.
