Abstract
A combined sclerotherapy and light treatment method is described for the treatment of unwanted veins such as varicose and telangiectatic leg veins. Substantially increased success, in the range of 90-100%, has been achieved by implementing a dwell time of between 12 hours and 6 months between the light-based therapy and the sclerotherapy. Near infra-red wavelength light is preferably used in the light therapy due to its better depths of penetration through the skin to deeper lying, larger vessels such as varicose veins.

A method for treating unwanted blood vessels, comprising:
- irradiating the vessels with light to denature the vessels or vessel walls;
- performing sclerotherapy on the vessels;
- and
- waiting for a dwell time of from 12 hours to 6 months between the irradiation of the vessels and the sclerotherapy.
A method for treating unwanted blood vessels, comprising:
- observing the unwanted vessels for size;
- selecting a pulse duration for the irradiation based upon the observed size;
- irradiating the vessels with light of approximately 755 nm for the selected pulse duration to initiate destruction of the vessels;
- waiting for a dwell time of between 12 hours and 6 months after the irradiation of the vessels to allow the effects of the irradiation to mature;
- and
- performing sclerotherapy on the vessels after the expiration of the dwell time.
