The most effective well proven procedure, Sclerotherapy employs a tiny needle for the injection of a solution directly into the affected vein. This relatively painless injection causes the vein to close and disappear from view. The number of spider veins injected depends on the size and location of the cluster of spider veins and the patient's overall medical condition. Several treatments may be needed for optimal results.
Less effective, heat generated by Laser is used to destroy spider veins.
