“Intraoperative Ultrasonography” has timely become a title of the “How I do It” sessions to be held at the 9th International Congress of Neurological Surgery, in India, in October 1989. Dr. Koivukangas in Oulu, Finland, and I were appointed as the chairmen. Porf. Sambasivan, chairman of the Scientific Committee, suggested that the whole planning, including the recruitment of experts would be in our hands.
At this point, it may be worthwhile to review the history of intraoperative use of ultrasonography. It was Lyle French in Minnesota who first applied the ultrasound probe to a cadaver brain. Oscar Sugar and Sumio Uematsu in Chicago are known to be the first in using the technique intraoperatively. However, Kenji Tanaka and the Juntendo group in Tokyo apparently wrote on Intraoperative use of ultrasonography as early as 1961. Shin Ueda wrote on intraoperative use of B mode ultrasonography in 1968. However, this technique has never gained general acceptance from neurosurgeons and gradually become almost forgotten with the introduction of CT scanners in the medical world.
I first used the real-time linear-array scanning probe intraoperatively on the brain surface on October 16, 1979, probably the first in the world. In December I changed to the sector-scanning probe, and performed needle aspiration and tumor biopsy under ultrasound monitoring. These experiences were published in 1980 and, in detail, in 1981.
In late 1980, two other similar reports were published. First, by Voorhies and Patterson, and secondly by Jonathan Rubin and co-authors in Chicago. The latter work dealt with an experience of a cerebellar tumor depicted by the dural application of a sector-scanning probe. Later in 1982, their group first published a paper concering the use of ultrasound probe over the spinal cord. In 1983, Joachim Gilsbach in Freiburg published a monograph on the intraoperative use of a mini-Doppler probe. In 1988, the merit of intraopertive color-flow Doppler imaging was introduced by William Chandler and his group in Ann Arbor, Michigan. I believe that the intraoperative use of ultrasound has now become widely accepted in the neurosurgical field.
