Ergebnisse der klinischen Erprobung der Operationszugangsplanung mit NeurOPS
Bildgebende Systeme liefern dem Neurochirurgen eine Ftille von Bildmaterial mit standig steigender Qualitat, deren praktischer Nutzen fur die Operation und deren Planung nur seiten hinterfragt wird [5]. Der klinische Einsatz einer computergestutzten Planung wird vor allem durch den notwendigen Zeitaufwand zur Rekonstruktion, weniger bei der Planung selbst, behindert. Das Programm NeurOPS wurde speziell fur die Planung patientenindividueller Zugangswege fur einen minimalinvasiven Eingriff in enger Zusammenarbeit mit Neuroradiologen und Neurochirurgen entwickelt. 1998 wurde abschliesend eine umfangreiche klinische Erprobung durchgefuhrt.
Real and simulated endoscopy of neurosurgical approaches in an anatomical model
Endoscopy simulation is a new visualisation technique which can be used to visualise patient anatomy as seen through endoscopes. In the following, we describe the application of simulated endoscopy to neurosurgical endoscopic approaches. We assess different aspects of virtual images and their influence on the final result, as judged by clinicians. One of these aspects is the projective geometry which is used to render the 3D images. Rendering using stereographic projection leads to more realistic endoscopic views than perspective projection.
Endoscopic Third Ventriculostomy: Outcome Analysis of 100 Consecutive Procedures
OBJECTIVE: Endoscopic third ventriculostomy (ETV) has been shown to be a sufficient alternative in the surgical treatment of occlusive hydrocephalus. To elucidate the ongoing discussion of timing, indication, and surgical technique, a retrospective analysis of 100 consecutive ETVs was conducted. METHODS: One hundred ETVs were performed in 95 patients (43 female and 52 male patients). Their age ranged from 3 weeks to 77 years (mean age, 36 yr). Hydrocephalus was caused by aqueductal stenosis in 40 patients, space-occupying lesions in 42, and intraventricular or subarachnoid hemorrhage in 8. One patient had postinflammatory hydrocephalus, and four patients had occlusive hydrocephalus of unkno…
Endoscopic Anatomy of the Ventricles
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.
