It is a treatment that utilizes a chemical solution that is injected into the vein, causing the vein to collapse and disappear from view. This is often utilized when the vein may be too large to effectively be treated with laser alone, or to decrease the number of laser treatments needed.
Treatment usually takes 30 minutes and the number of injections varies, depending on the extent of damage. Multiple treatments may be necessary for complete clearance. Laser therapy is often used in conjunction with Sclerotherapy for optimal results.
