Ultrasound-guided periventricular stereotaxis
Neurosurgery, 1984Intraoperative ultrasound can aid the biopsy of deep intracranial lesions. It is, perhaps, less clear whether ultrasound could be useful in functional neurosurgery, where the target is not abnormal in echogenicity. As an example, we chose to investigate in a dog model the periventricular gray target, which is frequently the choice for the placement of ...

The British Journal of Radiology, 1960
We have been using Leksell's Stereotactic Instrument, at the National Hospital and at Atkinson Morley's Hospital, in the treatment of Parkinsonism and other conditions characterised by involuntary movements and disturbances of tone, and also for the implantation of radioactive gold grains into tumours which are fairly well localised and deeply situated.

Frameless Stereotaxy in Children
Pediatric Neurosurgery, 1994Frameless stereotaxy provides stereotactic localization without a standard stereotactic frame. Other reference points on the patient are linked to radiographic images by means of a three-dimensional (3D) digitizer. We report the use of a frameless stereotactic system to assist in 53 procedures in 52 children using the ISG Viewing Wand system (ISG ...

Stereotaxy and behavioural disorders
Acta Neurochirurgica, 1993A series of 35 selected non senile patients was investigated with stereotactic brain biopsies in frontal and temporal lobes including the rhinencephalon. Results of neuropathological studies are confronted with clinical proposals. Alzheimer's disease is diagnosed in about 10% of the cases under 50 years of age, but more than 50% after 50.

Stereotaxis and Abnormal Movements
1987A series is presented of 106 patients with extrapyramidal syndromes treated by stereotaxy. The importance of preoperative screening to assure favorable results is stressed. Surgical contraindications are elderly patients with dementia and akinesia. Axial dystonia and spasmodic torticollis respond poorly to stereotaxy; and bilateral interventions should

Radiology, 1969
Implantation of an electrode or probe into the brain by stereotaxis requires accurate biplane radiography to define the target. The x-ray image of the target may be seen directly (e.g., an ancurysm filled with contrast medium) or, as is usually the case, indirectly by measurements from coordinate points outlined by contrast medium (e.g., in ...

New possibilities for stereotaxis. Information-guided stereotaxis.
Stereotactic and functional neurosurgery, 2002Information-guided stereotaxis, assisted by visualization of medical information, will become the next generation of neurosurgical systems. We performed 76 open MRI surgeries at Tokyo Women's Medical University between March 3, 2000 and April 12, 2001. Of them, comparisons of pre- and post-operative MR images for malignant gliomas in 21 cases revealed ...

History of spinal cord stereotaxy
Journal of Neurosurgery, 1996✓ Stereotactic and functional neurosurgery has experienced a remarkable degree of development during the last 50 years, from the plaster of Paris frame of Spiegel and Wycis to the technology of frameless stereotaxis. Although predominantly used for intracranial procedures, stereotaxy has its roots in experimental studies of the spinal cord.

Stereotaxy: Procedural Aspects
2021Human stereotaxy celebrates a twenty-fifth anniversary in 1972. It has been a quarter of a century since the pioneer probe of Wycis and Spiegel penetrated the deep arcane structure of the brain?s central core. ? Riding the crest of a post World War II tidal wave of technological expansion, stereotaxy borrowed shamelessly from the creative explosion to ...

Spinal Cord Stereotaxy: An Overview
Journal of Neurological Surgery Part A: Central European Neurosurgery, 2015The origin of spinal cord stereotaxy can be traced back to the 19th-century work of Woroshiloff, the pioneer of brain stereotaxy. The development of clinical brain stereotaxy began in the mid-20th century, but spinal cord stereotaxy lagged behind. The first stereotactic spinal cord surgery was successfully performed by Hitchcock for pain treatment in ...
