Computer-Assisted Neurosurgery by Eiju Watanabe (auth.), Norihiko Tamaki M.D., Kazumasa Ehara

By Eiju Watanabe (auth.), Norihiko Tamaki M.D., Kazumasa Ehara M.D. (eds.)

Computer expertise has constructed remarkably within the box of neurosurgery prior to now 10 to twenty years. nice achievements were made lately in neuroimaging innovations and machine expertise for neuronavigation, from frameless, armless platforms to robot microscopes. inside the current quantity are all of the papers offered on the overseas Symposium on Computer-Assisted Neurosurgery and chosen papers provided on the sixth Annual assembly of the japanese Society of pcs in Neurosurgery, that have been held in Kobe, Japan, on January 24-26, 1997. This quantity is a accomplished description and evaluation of present technical advert­ vancements in computer-assisted neurosurgery, with a unique specialize in complicated intraoperative neuroimaging, numerous neuronavigation process, robot microscopes, and techniques for preoperative and intraoperative surgical making plans utilizing high-power workstations with 3-dimensional software program. We convey our because of the individuals for his or her participation and cooperation, and to Springer-Verlag for private and technical information in publishing this paintings. We basically wish that this quantity will give a contribution to bettering neurosurgical know-how and outcomes.

Brain Tumors in Adults, An Issue of Neurologic Clinics

In 2007, among forty. 000 and 50,000 humans within the usa should be clinically determined with basic mind tumors, the vast majority of whom might be adults. 3 times this quantity will improve metastatic mind tumors from melanoma originating in other places within the physique. This factor of Neurologic Clinics comprises the next articles: Epidemiology of mind Tumors (Wrensch, Claus); Molecular Pathogenesis of mind Tumors and the position of Stem Cells (Ligon, Kesari); Advances in Neuroimaging of mind Tumors (Henson); clinical administration of mind Tumor sufferers (Schiff, Wen); Advances in Neurosurgery for mind Tumors (Shaffrey); Advances in Radiation treatment for mind Tumors (Mehta); Novel treatments for mind Tumors (Wen, Schiff); Anaplastic Astrocytomas and Glioblastomas (Reardon); Anaplastic Oligodendrogliomas and Anaplastic Oligoastrocytomas (Van Den Bent); Low-Grade Gliomas (Lang, Gilbert); mind Metastases (Deangelis); Benign mind Tumors (Link); fundamental CNS Lymphoma (Abrey); and Genetic factors of mind Tumors (Plotkin).

Transendoscopic Ultrasound for Neurosurgery

Endoscopic neurosurgery has now not but reached the security and applicability of microsurgery. Endo-neuro-sonography is a brand new strategy aimed toward making endoscopy more secure by way of real-time imaging and navigation ability (brain-radar). The endo-neurosonographic snapshot is a sonographic experiment on the tip of the endoscope (mini-CT) providing additional info to the endoscopic view.

Handbook of Complex Percutaneous Carotid Intervention

This guide vitamins hands-on education in interventional cardiology with a selected concentrate on percutaneous intervention in sufferers with extracranial carotid artery stenosis. It includes reports of landmark reviews aiding carotid endarectomy and stenting and is a accomplished advisor to this interesting and burgeoning box.

Peripheral Nerve Surgery: Practical Applications in the Upper Extremity

This useful and complete e-book provide you with contemporary top wisdom at the therapy of nerve accidents from the brachial plexus to the fingertip. Pioneers in peripheral nerve surgical procedure from throughout North the United States and Europe provide you with guidance, pearls, and technical issues gleaned from their a long time of expertise.

Example text

Imaging data acquisition, software, and a digitizer device are the minimal requirements. We present our experience using a system in which a microscope was coupled to a robotic holder. Limitations encountered were related to the need to maintain the patient's head in a fixed position and to easy loss of registration in deep areas. These limitations were overcome by integrating an infrared system that allowed movement of the patient's head during surgery while tracking the accuracy of intraoperative registration.

The pathology was consistent with a metastatic tumor. After a total resection of the right parafalcine lesion (b), she underwent external beam radiation therapy and radiosurgery for the left thalamic lesion a b 52 1. Zamorano et al. masses, a right parietal parafalcine and a left thalamic (Fig. 3). Further workup revealed a lung mass, which proved to be a metastatic lesion from a melanoma. Her intracranial lesions were approached in a stepwise fashion consisting of a craniotomy and resection of the right metastasis followed by radiosurgery for the left thalamic lesion.

In addition to the clinical advantages, the economical impact of shorter hospitalization time (as reported by several publications) on health care costs should not be ignored.
