Microsclerotherapy is considered the gold standard treatment for leg thread veins and spider veins. It is the technique of injecting thread or spider veins with a special substance known as a ‘sclerosant’ that causes swelling in the vein’s wall. 
If the vein is small enough, the swelling will destroy the vein over several weeks, making it much less noticeable or even invisible.

Dr Joney De Souza is a master trainer in this procedure at Wigmore Medical in London where he trains other medical doctors to carry out this treatment. He is an expert in this field.


“I initially came to Dr Joney for treatment for my leg thread veins; we worked together on clearing most of them and now I come on six-monthly maintenance sessions. My legs have never looked so good and my confidence has improved no end too!”

What can microsclerotherapy do for me?

The appearance of tiny red or purple veins in the skin are commonly know as thread veins or spider veins. Many people who have these feel less confident about wearing shorts or summer clothing which expose their legs, and they often ‘cover up’ because of this. The reason why people develop thread veins is not fully understood but the known and most important causes include heredity, pregnancy, hormones and minor injuries. Microsclerotherapy can be used to treat these unsightly veins so that you can return to wearing the clothes you feel confident in.

Who is suitable?

Dr Joney De Souza will take your medical history and assess your suitability for microsclerotherapy treatment at your free consultation.

What is microsclerotherapy treatment like?

There is usually very little discomfort during microsclerotherapy injections due to the size of the needle and the superficial injection technique.

Dr Joney will inject sclerosing agent into the thread veins using a very fine needle. The solution has an irritant effect on the lining of the veins causing the wall of the veins to stick together. Blood stops flowing through the veins, which are then absorbed by the body’s natural defence mechanism over a period of time. The blood is then directed back to the deeper venous system.

Following microsclerotherapy injections, a swab may be taped over the treated area, and often a special bandage and compression stocking is applied which may be worn for several days to help assist shrinkage of the thread veins. 

A single blood vessel may have to be injected more than once, depending on its size.
 Repeat injection sessions can be scheduled one week later, but it is better to wait one month between treatments. 
In practice, most patients require between two and six treatments at four to eight week intervals.

It is common for around 75% or more of your veins to vanish, but you should be aware that 100% disappearance of all veins is rare.

The whole treatment should usually take no longer than half an hour or so – depending on how many veins require treatment.
 You can normally drive immediately and go about your usual daily activities following this treatment.

What happens afterwards?

Some pain or burning at the injection site may occur following injections, and some patients experience restlessness in their legs during the first few nights. This is due to the swelling of the walls of the veins.

For a month or so, the vessels may appear more prominent. The injection sites look like insect bites and may occasionally itch. The veins gradually begin to fade and continue to improve for up to eight weeks.

Complications are very rare following microsclerotherapy, but the solution can sometimes escape from the veins and cause inflammation in the skin surrounding the treated area. There is also a small risk of the development of tiny ulcers, which may leave a small pink or white scar on healing.

Occasionally you may also find new veins developing in the treated areas, or even old veins flaring up again.
