Length
15 to 45 minutes

Side Effects
Sclerotherapy: Temporary cramping. Bruising and reddish areas at the injection site. Brownish pigmentation may take up to a year to fade. Laser therapy: minor bruising.

Recovery
Sclerotherapy and laser therapy: No downtime; patients can immediately return to work and resume all normal activities. Refrain from vigorous activities for first 24 hours.

Risks
Sclerotherapy: Formation of blood clots in the veins, severe inflammation, adverse allergic reactions, and skin injury. Cosmetic complications include pigmentation irregularity and telangiectatic matting; the development of new tiny blood vessels around the treated vessel, requiring further injections. Laser therapy: Semi-permanent or permanent skin lightening in treated areas. Burns or injuries caused from heat.

Results
Sclerotherapy and laser therapy: The appearance of spider veins is significantly diminished, with skin returning to a more natural state. Both treatments may require multiple "touch ups," and do not prevent the emergence of new spider veins.

Technology
During Sclerotherapy, one injection is administered for every inch of spider vein, causing the lining of the vein walls to swell, stick together, and eventually seal shut. (Electrodesiccation is similar to Sclerotherapy except the veins are closed off with an electrical current instead of injected solution). Laser surgery directly sends strong bursts of light onto the vein, making it slowly fade and disappear. All skin types and shades can be treated with laser surgery.
