Microsclerotherapy for Spider Veins

Microsclerotherapy is a non-surgical and effective method to treat unsightly veins.

It is done by injecting a solution called sclerosant into an unsightly vein to make it disappear. The sclerosant damages the cells lining the blood vessel wall, which scars and is reabsorbed by the body. Some immediate blanching of vessels will be seen at the time of treatment.

The full reaction is slow, taking at least six weeks, with improvement continuing beyond this time, but the reaction varies between individuals.

Firstly, we will take a full medical history and you will have the opportunity to discuss any treatment aspects with your Cosmetic Doctor and Nurse team. We will determine exactly if your veins can be treated with microsclerotherapy or if you will require ultrasound mapping of your veins to check whether the valves are working (varicose veins).

If appropriate, injections are given into the vein using a very fine needle. Due to its local anaesthetic quality the treatment is fairly painless with only mild discomfort.

Multiple treatments  are required to have the desired effect (usually 3 to 4 depending on individual factors).

Each treatment tends to improve the appearance by 50%. Appointments are for an hour and are repeated at monthly intervals.

Yes, the side-effects are mainly cosmetic and usually resolve. Severe allergic reactions to sodium tetradecyl sulfate have been reported, but they are very rare. No deaths have been recorded following the use of it.

Rarely, a Deep Vein Thrombosis or DVT which is a clot in the deep veins, has been reported. That is why it’s important to follow our post treatment instructions.

Not varicose veins. They need Ultrasound Guided Sclerotherapy (UGS) or surgery. We do not treat varicose veins at OPA.

Minimum of 30-60 minutes walking per day.
Wearing the compression stockings for 7 days after treatment. 24 hours a day for the first 3 days and then you can take them off whilst sleeping for the next 4 days. Avoid sun exposure to the treated areas until all bruising has resolved to prevent pigmentation.

Discomfort: Usually mild. An short lived itching or mild burning sensation is not uncommon. Bit like a bee sting.

Discolouration: This is caused by pigment leaking from the red blood cells along the course of the treated blood vessels. It happens unpredictably in about 30% of people and has the appearance of an old bruise. Pigmentation disappears over time but may take as long as 12 months to resolve. We know that the use of compression stockings following treatment is essential to minimise the occurrence of pigmentation.

Vein Matting: This refers to the appearance of new, very fine red blood vessels in response to sclerotherapy. This occurs in a minority of patients. Its cause is unknown and it may not be easy to treat.

Skin Ulcers: These can occur at the injection site or further away. These are rare with Polidocanol.

Haematoma: This is a small amount of clotted blood within the injected vessels which may need to be released by puncturing the area and expressing the clot. It occurs more commonly in larger varicose veins. It causes a dark lumpy discoloration along the course of the vein but usually disappears within a month.

Pregnant women.
Previous history of deep vein thrombosis.
Long distance travel within a month of treatment.
