Question
What is foam sclerotherapy?
What exactly is foam sclerotherapy, and is it more effective than traditional sclerotherapy?

Answer
Foam sclerotherapy means combining the sclerotherapy medication with air to generate a foamed solution. This is then injected into the veins to promote absorption and resolution.
The stronger foamed agents are not necessary for the treatment of spider veins. Foam is reserved to the treatment of larger varicose veins that your doctor feels would be under-treated with the sclerosing agent alone.
Micro-phlebectomy is another procedure that is highly effective in treating varicose veins for which foam might be recommended.
