Spider veins most commonly occur on the legs of women, though they can occur in men as well. They are clusters of small red and blue blood vessels found often on the thighs, calves, and ankles. Many factors contribute to their development, including:
- Hormonal changes or medications
- Sitting or standing in place for long periods of time
Treatment of spider veins is successfully achieved with injections into these unsightly clusters with specialized solutions, including Asclera® (polidocanol), sodium tetradecyl sulfate (STS), and hypertonic saline. These solutions damage the lining of the veins, leading to their eventual disappearance. Successful results may require multiple treatments.
