“…Krishna et al reported on five patients with Charcot-Marie-Tooth disease in whom somatosensory evoked potential monitoring was impossible to perform during spinal surgery 16 . Intraoperative neurologic monitoring has become standard practice in our institution, but we found that it is rarely possible to monitor either somatosensory or motor evoked potentials during surgery in patients with Charcot-Marie-Tooth disease because of the demyelinating polyneuropathy.…”

“…In many cases with large surgical procedures in which the entire cross-sectional area of the spinal cord is threatened, this expectation can be realized. However, as might be expected, there have been examples where focal injuries have failed to be detected by monitoring of posterior column function alone [1,3,5,6,9,10,12]. There are reports in the literature which document no false negatives in SSEP monitoring of spinal surgery [11,18].…”

Somatosensory evoked potentials (SSEPs) have been used to help minimize neurologic morbidity during spinal surgery. While this is a sensory test it has been used as an inference of motor function. The failure to always achieve the latter goal has resulted in some pessimism regarding the value of this test. In this series of 161 operations in 150 patients, it was demonstrated that SSEPs were recordable under anesthesia in 87% of patients. Of these patients, 12% had their spinal surgery interrupted due to significant neurophysiologic changes; of these patients, 18% had new neurologic deficits postoperatively. There were no cases with new neurologic deficits who had no changes in their SSEPs. It was concluded that SSEP monitoring may be helpful in identifying potentially neurologically threatening surgical maneuvers in a significant number of patients.

“…BERENSTEIN et al (1984) described the use of SSEP monitoring in 42 angiographic examinations during 33 therapeutic embolizations in 41 patients. Focal motor deficits have been documented when monitoring posterior column function with normal SSEPs (BEN-DAVID et al 1987;KATSUTA et al 1993;KRISHNA et al 1991;LESSER et al 1986;MUSTAIN and KENDIG 1991;GINSBURG et al 1985). After angi-0graphy withdrawal of the catheter tip engaged in the artery resulted in recovery of the baseline waveform within 2-4 min, except in a patient with a cervical AVM, which required 24 min after discontinuation of the procedure.…”

Cover design: de'blik, Berlin Typesetting: Verlagsservice Teichmann, Mauer SPIN,10111594 21/3135 -5 4 3 210 -Printed on acid-free paper ForewordSpinal Tumors are relatively rare conditions, but they present distinct and specific clinical and radiological features.Modern radiological imaging techniques, especially the new cross-sectional methods such as CT and magnetic resonance imaging, allows us nowadays to depict the exact localization and extent of these lesions more clearly. Moreover, the specific findings of these different morphological diagnostic modalities yield deeper insight into the exact nature of these tumors and their differential diagnosis.During the past few years, important progress in the therapy of spinal tumors has been achieved. Information about these new developments, however, is disseminated throughout the medical literature and scattered across the different medical disciplines. Furthermore, opinions regarding the best diagnostic approach and/or therapy are not always concordant.The editors of this book should be congratulated to bringing together several international authorities with particular expertise in the diagnosis and the treatment of spinal tumors.Together, these authors provide a complete overview of the currently prevailing diagnostic algorithms and therapeutic strategies for spinal tumors.The book will therefore suit excellently the needs of all physicans involved in the management of patients which such tumors: neurologists, neurosurgeons, orthopedic surgeons and radiologists. It will be of particular interest to radiologists, who are nowadays responsible not only for the diagnosis of these tumors but also, in some cases, for their non-surgical treatment.Leuven ALBERT L. BAERT PrefaceMany different opinions exist on the diagnostic workup and, particularly, on the therapy of spinal tumors. For instance, there is no consensus on the optimal treatment of spinal compression caused by vertebral metastases.With the advent of new imaging techniques (MRI) and therapeutic regimens, an up-to-date reference work is needed. This book is the first of its kind in that it offers an overview of the opinions of internationally renowned specialists. The editors hope this publication will help to establish rational imaging and therapy protocols for spinal tumors.Alkmaar Amsterdam Amsterdam
