Abstract

Background and Objective: Histological effects of 2.1-mu m Ho:YAG and1.06-mu m Nd:YAG laser pulses were compared in the rat brain, with special regard to areas remote from the irradiated site. Study Design/Material and Methods: Laser pulses were delivered through a 0.6-mm glassfiber, the tip of which was either introduced into the caudate nucleus (application mode I), or held at a 2-mm distance above the exposed intact dura. In the latter case, the space between the dura and the fiber tip was filled either with physiological saline (application mode II) or with air (application mode III). Results: In application modes Iand II, but not in application mode III, Ho:YAG; laser pulses of 1.5 J and 200 mu s, but not Nd:YAG laser pulses with the same parameters, immediately caused morphological damage to a considerable number of neurons and axons randomly distributed among apparently normal ones in certain areas remote from the irradiated site. A decrease in the energyand an increase in the length of the pulses lowered the incidence of the remote morphological damage. Conclusion: This novel finding may impose limits on the application of Ho:YAG; lasers in human endoscopic neurosurgery. (C) 1997 Wiley-Liss, Inc.
