What is foam sclerotherapy?
In sclerotherapy a sclerosing agent that irritates the inner vein wall is injected into the vein through a fine needle. In foam sclerotherapy the agent is mixed with air to form a foam that contacts a larger surface inside the vein, so it may be preferred for larger veins.
How is it done?
The vein is accessed with a millimetre-thin needle, under ultrasound if needed, and the foam is injected. The treated vein sticks together, closes and is absorbed within a few weeks. A compression stocking is applied afterwards.
Aftercare
Temporary bruising, mild pain, redness or dark marks may occur. Some patients need more than one session.
- Wear compression stockings for the recommended period
- Walk lightly and avoid heavy exercise
- Avoid hot baths and saunas for a while
- Attend follow-up appointments
