Sclerotherapy treatment

What is Sclerotherapy Treatment?

Sclerotherapy treatment is used to treat varicose veins, thread veins and venous malformations. A liquid solution is injected very superficially into the blood vessels using an ultra-fine needle. Compression is then applied to cause the veins to shrink and eventually fade away altogether. Larger varicose veins can also be treated using a foam solution which is performed under ultrasound guidance.

What are the benefits of sclerotherapy treatment?

Sclerotherapy is a very safe and well-established treatment for reducing the appearance of unwanted thread and spider veins. Although there are many alternative procedures available, sclerotherapy treatment remains the most reliably successful available. The injections are virtually painless, and normal activity can be resumed as soon as fifteen minutes post-treatment. Foam sclerotherapy can be an alternative to surgery for larger varicose veins.

How safe is treatment?

Though safe, liquid sclerotherapy is not entirely without risk. The two most common side effects are haemosiderin deposition and telangiectatic matting. Haemosiderin deposition occurs when blood is trapped inside the vein and clots, causing iron pigments to stain the skin over the vessels brown. These marks are not usually permanent, but may take between 6-18 months to fade. Matting occurs if the fragile vessel is injured during the injection, leaving a mat of tiny veins that look like a blush or red bruise. Matting usually disappears completely after 6-12 months¹. Foam sclerotherapy treatment can carry a risk of permanent skin staining, visual disturbance and headaches as well some more serious although rare side-effects. If this treatment is suitable for you your doctor will provide further information about this.

How many sessions are required?

The number of sessions you require may vary, depending on the size or number of areas that need sclerotherapy treatment.
