This case study aimed to evaluate the effectiveness of surgical intervention in treating NPH associated with spinal cord tumors. A patient suffering with NPH underwent a spinal tap procedure and surgical resectioning of three neurinomas on the cauda equina. The patient exhibited marked improvement in neurological and motor symptoms related to NPH following surgical intervention. These findings suggest that surgical resectioning of neurinomas is an effective intervention for treating NPH associated with spinal cord tumors.展开更多

Based on the experience of about 687 cases in a 20 year time period our mostly used techniques will be presented. This is a minimal invasive individual adapted approach, specified intraoperative strategy and dissection techniques (e.g. water jet dissection, ultrasonic aspirator CUSA), the use of neuronavigational systems and the use of endoscope assisted surgery. With respect to the limited space of place precise citations to further textbooks of the authors handling with this topic will be given. Finally our results using these techniques are presented and further future perspectives in the treatment of these pathology (radiosurgery) will be discussed.展开更多
