Abstract
Laser energy has been shown to vapourise thrombus and atheroma in the experimental setting [1,2], raising hopes that it may have a role in angioplasty. The three laser wavelengths in common medical use are argon, neodymium yttrium aluminium garnet (NdYAG) and carbon dioxide. Both argon, in the visible blue-green part of the spectrum absorbed by haemoglobin, and NdYAG, in the near infrared part, have been used in angioplasty experiments. Carbon dioxide, in the far infrared part of the spectrum, has been used experimentally [3] and intra-operatively in the coronary arteries [4], but its use during percutaneous catheterisation is not presently possible because it cannot be transmitted by flexible non-toxic fibres.
