Sclerotherapy

Sclerotherapy effectively treats thread and spider veins. It's often considered the treatment of choice for small unsightly veins. During sclerotherapy, the physician injects a solution directly into the affected vein. The solution irritates the lining of the vessel, causing it to swell and stick together. Over time, the vessel turns into scar tissue that fades from view. Sclerotherapy is a well-proven procedure and has been used since the 1930s.

Sclerotherapy works well for most patients. It is estimated that between 50 and 80% of injected veins may be eliminated with each session. In general, spider veins respond to treatment in 3 to 6 weeks, and larger veins respond in 3 to 4 months. If the veins respond to the treatment, usually they will not reappear. However, new veins may appear over time. If needed, you may return for injections.
