Since the advent of electrosurgery the concepts of surgical procedure at the anxious process have gone through additional advancements (bipolar coagulation, microscope), whether the process was once no longer considerably changed. at the present time, laser represents a brand new "discipline", because it deals a brand new means of acting all simple maneuvers (dissection, demolition, hemostasis, vessel sutures). additionally, laser bargains the opportunity of a different maneuver, particularly relief of the amount of a tumoral mass via vaporization. Its software isn't limited to standard neurosurgery yet extends additionally to stereotactic and vascular neurosurgery. Laser surgical procedure has additionally prompted the anesthesiologic strategies. even as new instrumentation has been brought: CUSA ultrasonic aspiration, echotomography, and Doppler flowmeter. i've got had the opportunity to make use of those new applied sciences all at a time and feature come to the belief that we face the sunrise of a brand new technique which has already proven its validity and shortage of inconveniences, and whose item is to extend the precision of neurological surgical procedure. The technological improvement continues to be occurring, and a few advancements are to be foreseen. Laser scalpel is splitting the preliminary laser surgical procedure into NO­ contact and contact surgical procedure with laser. As new instrumentarium should be built, a variable and tunable beam turns into to be had. for instance, in many years unfastened Electron Laser will extra upload to the growth during this field.

In clinical practice the angle dependency of the Doppler method does not have the significance which can be assumed from the cosinus function. During tke operation, the probe is adjusted acoustically and under direct vision according to the best Doppler signal. The incident angle then lies constantly between 40 and 60 degrees (Eldridge et al. 1979, Gilsbach 1983, Kaneko et al. 1970). The majority of the medical Doppler ultrasound systems are so-called continuous wave systems (CW Doppler). In these devices, one crystal continuously emits and another crystal continuously receives the ultrasound.
