This treatment is only used after the main superficial veins
prove to function normally with no reflux as confirmed by
ultrasound, or if they have been treated already. The
concentration used will vary according to the size of the vein
treated. This type of treatment is used for
spider veins and
surface varicose veins.

Spontaneous clearing within

The cause is unknown. It is possibly associated with
obesity, longer duration of spider veins and exposure to excess
estrogens. Although matting may be permanent, it
usually resolves spontaneously over several months. Areas of
matting may be treated with sclerotherapy or laser
