摘要

The 2 primary objectives of this study were to investigate whether the 1470-nm wavelength can close a saphenous vein painlessly and determine safety, efficacy, and side effects of the 1470-nm laser. In all, 26 limbs were treated in the Dominican Republic, with a radially-emitting fiber at low energy ranging from 20 J/cm to 30 J/cm. Perivenous anesthesia was used selectively. Then 41 veins were treated with the 1470-nm laser at 30 J/cm at 5 watts, using standard perivenous tumescent anesthesia in Miami and compared to a historical control (980 nm, 80 J/cm, and 12 watts). We demonstrated that the 1470-nm wavelength endovenous laser system could not close saphenous veins without use of anesthesia. Closure with a dramatic reduction in energy when compared to a 980-nm wavelength control demonstrated a marked reduction in postoperative pain and ecchymosis; this implies that vein-wall perforations are minimized with this system.
