Ultrasound Guided Sclerotherapy

Sclerotherapy is the most common treatment for improving the appearance of varicose and spider veins on the legs and is one of the latest methods for the non-surgical treatment for varicose veins that we offer at Fraser Clinic.

For a long time the only treatment for large varicose veins was to have them surgically stripped. This requires a general anaesthetic (with its associated risks) and often a prolonged and sometimes painful recovery. Furthermore, the recurrence rates following surgery are significant, (at least 30% recurrence within 5 years in some reported studies), requiring further surgery.

Smaller veins are not always suitable for surgical stripping (they are too small) and often require sclerotherapy treatment to get a more complete result.

Sclerotherapy is an internationally recognised treatment that involves the injection of special solutions to irritate the inside of the vein wall and turn the soft hollow vein into a solid fibrous cord. Blood no longer passes through the treated vein, but this doesn’t matter as blood can return to the heart via the deeper veins.

How the treatment is done

The same ultrasound machine that is used to map the veins is used to guide the insertion of a fine needle into the affected varicose vein, so a small dose is used to treat a large section of vein with great accuracy and safety.

Once injected, the treated vessel will be gradually absorbed by the body and will disappear with time. A number of injections will be required along the length of the vein to achieve complete closure. Another significant benefit of this procedure is that it allows the Surgeon to monitor the effect of each injection, while ensuring the safety of all adjacent structures, such as arteries and nerves in the leg.

What is used for the treatment

Since 2001, in line with international trends, we have used a special foam in order to treat varicose veins. Foam is much more easily tracked on ultrasound, allows smaller doses to be used and is much more efficient at closing varicose veins.

How long the treatment takes

The treatment takes up to half an hour to complete, and we usually see our patients at one week and then at eight weeks for routine follow ups.
