Foam sclerotherapy is a new form of delivering the sclerosing agent that allows us to treat larger varicose veins that might be unsuccessfully treated with conventional sclerotherapy. The foam solution has the consistency of ‘shaving cream’, which improves treatment in two distinct ways.

First, the foam displaces blood within the vein, permitting the full strength of the sclerosing agent to be in direct contact with the vein wall for an extended period of time without any dilution effects.

Second, the foam is visible via ultrasound imaging and can be easily tracked and guided to the source of the venous problem. For large veins, foam is used with conjunction of the ultrasound machine.
