Laser treatment of leg veins: Physical mechanisms and theoretical considerations

PubMed Reference: Ross EV, Domankevitz Y. Lasers Surg Med. 2005 Feb.


  • 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.
