Comparison of Intraoperative and Transcranial Doppler
The first intraoperative Doppler investigations of intracranial arteries were described in 1979 by Nornes et al. They used a 6 and 10 MHz pulsed system in combination with small probes to record Doppler shifts from intracranial vessels. In 1983, Gilsbach reported on the use of a 20 MHz high resolution system which permitted the investigation of vessels as small as 0.1 mm in diameter, using sterilizable microprobes. Since the introduction of transcranial Doppler sonography by Aashd in 1982, comparisons between the pre- and postoperative transcranial findings and the direct intraoperative recordings of the same vessel in an individual patient have become possible.
