ENDO-NEURO-SONOGRAPHY - ANATOMICAL ASPECTS OF THE BASAL CISTERNS

To evaluate the usefulness of transendoscopic sonography, two sono cat heters of 6F diameter were studied in 15 fresh specimens. A precise im aging was seen of well known anatomical structures. An additional dime nsion in endoscopy was also obtained as the sono added to the endo vie w a transversal scan like a mini CT at the tip of the probe. The guidi ng characteristic of this imaging technique, which is in real time and on line, was also experienced. These observations offer such interest ing prospects for use in minimally invasive neurosurgery that further development and clinical experience seem to be justified.
