Observations on the use of three laser sources in sequence (co2-argon-nd: yag) in neurosurgery

In neurosurgical practice the laser can be considered an additional instrument to improve conventional techniques, or even a new method of treatment of some cerebral lesions. A complete laser surgery requires the association of three laser sources in combination. The CO2 laser is useful for cutting small lesions in important brain areas. Nd: YAG is particularly suitable for tumor surgery‐allowing a deeper destruction with predictable effects associated with a more complete hemostasis. The combination Nd: YAG‐Argon has clear indications for irradiation of the vessels.
