Minimally invasive | Little to no pain | Effective
Sclerotherapy is a simple, non-surgical treatment for varicose veins and spider veins. A small amount of a specially formulated solution (sclerosant) is injected directly into the affected vein using a very fine needle. The solution irritates the inner lining of the vein, causing it to seal shut. Over the following weeks, the treated vein gradually fades and is absorbed by the body.
The procedure is performed in the clinic, with no hospital stay, no general anaesthetic, and no incisions are needed.
The Procedure
Before Treatment
- Your surgeon will review your health history and examine your legs.
- An ultrasound scan will be used to map the veins and identify which ones need treatment.
- All options will be explained, and any questions answered, before anything proceeds.
On Treatment Day
- The veins to be treated are identified, often with ultrasound guidance.
- A very fine needle is used to inject the sclerosant solution directly into the vein. Most patients feel only a mild stinging sensation.
- The vein closes in response to the solution — this is the intended effect and is not painful.
- Compression dressings and stockings are applied before you leave.
After Treatment
- Some bruising, mild swelling, and temporary skin discolouration are normal.
- Wear your compression stockings as directed and avoid strenuous exercise, hot baths, saunas, and prolonged sun exposure to the treated area for 2-4 weeks.
- Spider veins typically fade within 3–6 weeks. Larger varicose veins may take 3–4 months to fully resolve.
- Sometimes more than one session is needed to achieve the best result.
