Sclerotherapy is a treatment that uses an injectable chemical called sclerosant into a varicose vein to damage and scar the inside lining of the vein. Sclerosant is an irritant, which works by targeting the main surface vein feeding the varicose veins and then eliminates all visible varices (dilated vessels).

Prior to the sclerotherapy treatment, the veins are mapped using an ultrasound machine and are marked with a pen. The patient is given an injection in the form of a local anaesthetic. A needle with catheter is then placed in the affected veins using ultrasound guidance. The patient’s leg is then raised to empty the veins. The sclerosant is injected through catheter tubes into the veins. There is no pain while the solution is being injected, but you may experience a minor stinging or burning sensation right after the injection.

Using ultrasound imaging, the attending practitioner makes sure that all the veins have been filled with the solution. Immediately following the procedure, the leg is bandaged and fitted with a compression stocking.

What to Expect

Step 1. Optional Free Consultation

We offer a free no-obligation 30-60 minute consultation with one of our specialist patient advisors to help you decide whether surgery is the right choice for you. The consultation will take the form of a discussion with an expert with over 15 years industry experience in which we begin to understand your objectives and the results you want to achieve.

If you decide to go ahead with treatment, our advisers can give you all the information you require to choose the right procedure and the right surgeon for you. This is also an excellent opportunity to see our facilities and get a feel for the Cadogan experience.

Step 2. Surgical Consultation

The next step is to come in and meet your chosen surgeon at the Clinic. We have assembled some of the best surgeons in the world who will use this time to make a comprehensive medical assessment of you and your condition before proceeding with treatment.

In practice this involves a 30-60 minute consultation in which a detailed assessment of the outcomes you can achieve is made and any questions you may have about the procedure are answered.

Step 3. The Procedure

On the day of your procedure you will be welcomed at the Clinic by your patient advisor and dedicated nursing staff. Following a brief medical check, you will meet with both your surgeon and anesthetist to run through the details of your procedure one final time and answer any last questions you may have.

After the procedure you will recover in the capable hands of your nursing after care team. As we are a day case facility you can expect your recovery to be complete within 2 to 3 hours and able to be discharged from the Clinic the very same day. In some cases patients may wish to stay locally in our exclusive partner hotel the day before or after your procedure.

Step 4. After Care & Support

Our care and support continues in the days and weeks after your procedure with our complimentary aftercare programme. A series of free appointments will be made with your surgeon and nursing team in order to monitor your progress and recovery, as well as introduce you to several scar minimization techniques and bespoke creams to aid your progress.

Access to our aftercare nursing team is free of charge for a full 12 months after your surgery.
