Loss of life was classified as because of pulmonary embolism, bleeding, or additional set up causes. Pulmonary embolism was regarded the cause of death if there was objective documentation or if loss of life could not be attributed to a documented cause and pulmonary embolism cannot be confidently ruled out. For the Acute DVT Study, the principal security outcome was clinically relevant bleeding, thought as the composite of major or relevant nonmajor bleeding clinically. For the Continued Treatment Research, the principal safety outcome was major bleeding. Criteria for bleeding were defined previously12 .Significant crusting and swelling were just reported with the 532nm wavelength. Visual improvement with the 940nm wavelength was greater than that accomplished with the 532nm wavelength. On photographic evaluation, the 940nm laser was more efficacious for larger caliber vessels than 532nm significantly. Both wavelengths were similarly effective for smaller caliber vessels. The 940nm diode laser beam was found to have greater efficacy for deeper blood vessels based upon its excellent penetration of the dermis with an extended wavelength. Furthermore, the 940nm wavelength corresponds with a lesser absorption peak of oxyhemoglobin than that for 532 nm, resulting in slower and more uniform heating system of the vessel, said lead author Emily Tierney, MD, an associate professor of dermatology at BUSM.
