Endo-neuro-sonography: principles and 3-D technique
1997
To evaluate the usefulness of transendoscopic sonography we studied two new sono probes 6 F in diameter in 17 fresh specimens. We saw precise imaging of well-known anatomical structures and also gained an additional dimension in endoscopy, as the sono adds to the endo-view a transverse scan like a mini-CT at the tip of the probe. We also experienced the navigation characteristic of this imaging technique, both in real time and on line. Some 3-D reconstructions of the ventricular system were examined. The equipment has been used in clinical practice and must now be adapted for neurosurgery.
Endo-neuro-sonography: Anatomical aspects of the basal cisterns
1997
SummaryTo evaluate the usefulness of transendoscopic sonography, two sono catheters of 6F diameter were studied in 15 fresh specimens. A precise imaging was seen of well known anatomical structures. An additional dimension in endoscopy was also obtained as the sono added to the endo view a transversal scan like a mini CT at the tip of the probe. The guiding characteristic of this imaging technique, which is in real time and on line, was also experienced. These observations offer such interesting prospects for use in minimally invasive neurosurgery that further development and clinical experience seem to be justified.
Endoscopic Anatomy of the Ventricles
1994
The endoscopic view offers a new anatomical dimension to the neurosurgeon. The fact makes it basically necessary to study the topographic anatomy under endoscopic conditions. In this paper attention was drawn to the ventricles because they are the most common region of clinical application. In 25 specimens neuroendoscopic explorations of the ventricles have been done. The dissections have been carried out through one- and two burr hole approaches (two working endoscopes at the same time). The instrumentation includes rigid 4 mm and 6 mm endoscopes. The procedures have been documented by continuous video recording and parallel photography.
