REVIEW PAPER

Based on Monte Carlo model to examine volumetric heat production, fluence rate, and temperature profiles in blood vessels at 1,064 and 532 nm wavelengths, review of literature and clinical observations
The 1,064-nm wavelength penetrates deeper in the skin than 532 nm (Fig.1)
Authors suggest that long pulses and long wavelengths are the best approach for side effect free clearance of leg veins 0.2–2 mm in diameter
Of the two primary clearance mechanisms, vessel contraction is favored over thrombosis.
