Neurosurgery, spine surgery, stereotactic surgery,

Dilan A Patel, Jian L Campian
Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established...

Pontificia Universidad Católica de Chile's medical school was founded in 1929. An interest in neurosurgical development arose in the minds of the Dean, Dr. Cristobal Espíldora, and the Chief of Surgery, Dr. Rodolfo Rencoret, in 1946. They encouraged and supported Dr. J. Ricardo Olivares to specialize in Neurosurgery with Professor H. Olivecrona in Stockholm, Sweden. The first neurosurgical procedure in the Hospital Clínico de la Universidad Católica was performed in 1950. Since then, intensive efforts have been made to develop neurosurgery and its science...

Gerard Guiot (1912-1998) was one of the most renowned and innovative neurosurgeons of the 20th century. His pivotal and revolutionary role in advancing transsphenoidal surgery has been recorded in many historical vignettes, yet his outstanding contributions to the advancement of neurosurgery outside the confines of the sella have not been described in a detailed fashion. In this article, the authors discuss the life and achievements of Professor Guiot and present a comprehensive description of his contributions to the field of neurosurgery, including cerebrovascular, spine, craniofacial, stereotactic functional, and endoscopic surgery...

BACKGROUND AND PURPOSE: The authors describe their own experience in use of intraoperative computed tomography (CT) with the Siemens SOMATOM Sensation in 125 cases. MATERIAL AND METHODS: Intraoperative CT of the head was most often used in functional neurosurgery for stereotactic planning in 32 cases and for control of deep brain stimulation electrode placement in 18 cases. In spine surgery, CT was used most often in spine stabilization to control the placement of implants...

BACKGROUND: Neurosurgical residency training paradigms have changed in response to Accreditation Council for Graduate Medical Education mandates and demands for quality patient care. Little has been done to assess resident education from the perspective of readiness to practice. OBJECTIVE: To assess the efficacy of resident training in preparing young neurosurgeons for practice. METHODS: In response to Resolution V-2007F of the Council of State Neurosurgical Societies, a survey was developed for neurosurgeons who applied for oral examination, Part II of the American Board of Neurological Surgery boards, in 2002 through 2007 (N = 800)...

Computer-assisted neurosurgery has become so successful that it is rapidly becoming indistinguishable from, quite simply, neurosurgery. This trend promises to accelerate over the next several decades, bringing considerable benefit to the patients we care for. From a pragmatic point of view, can we identify specific instances in which clinical practice has been altered by computer assistance? During craniotomies for the resection of brain tumors, this technology has led to a greater standardization within and among practitioners for the expected degree of resection and the risk of morbidity and mortality...

Radiosurgery is a minimally invasive technique designed to elicit a specific radiobiologic response at the target tissue using focused ionizing radiation delivered in single procedure. Radiosurgery was originally devised to treat intracranial lesions by delivering a high dose of radiation precisely at the intracranial target using stereotactic guidance. The term was coined and the field defined by Lars Leksell, a visionary leader of neurosurgery at the Karolinska Institute in Stockholm. Refinements in stereotactic methodologies, major improvements in dose planning software, and advances in neurodiagnostic imaging, all facilitated the increasingly broad application of brain radiosurgical methodologies...

Frameless stereotactic image guided surgery (IGS)--a fairly new modality originally used in cranial neurosurgical procedures--has been found to have several advantages over traditional framed methods of three-dimensional navigation. Frameless stereotactic IGS is proving useful in neurosurgical procedures by allowing screws to be placed in the spine more quickly and accurately than with traditional methods. As IGS becomes standard clinical practice for certain spinal procedures--overlapping both neurosurgery and orthopedic specialties--new ideas for surgical application of the technology are developing...

We prospectively studied the adverse operative events encountered during the first 4.5 years of a single neurosurgeon's career (JP). We investigated the incidence of these events and their distribution over time, and recorded risk factors in causation. Twenty-three adverse events were identified in 728 cases studied. These all occurred in one of four categories of operation: craniotomy, shunt placement, spinal surgery and stereotactic biopsy. The incidence of adverse operative events varied between 5.8% for spinal operations to 9...

An infrared based frameless stereotactic navigation device (Easy Guide Neuro) was investigated for its clinical applicability, registration/application accuracy and limitations in a standard operating room set-up. In a five-month period 40 frameless stereotactic procedures (23 female, 17 male, mean age 46.4, yrs range 10-83) including 36 craniotomies and 4 spinal surgery procedures were performed. Image registration, data transfer and operation planning using skin fixed fiducials (between 5-10, mean 6.6) and CCT in 12 patients/MRI in 28 patients, generally was done the day before surgery...

BACKGROUND: The philosophy and practice of minimally invasive surgery have fundamentally altered the practice of general and gynaecological surgery, and are currently transforming the practice of neurosurgery. The goal of minimally invasive surgery is to reduce tissue disruption and thus morbidity. This is a review of the development, applications, and benefits of minimally invasive neurosurgery, and its wider surgical implications. METHODS: A synthesis of the literature is presented...

Because of the limited application of frame-based stereotaxy to general neurosurgical procedures, we have carried out a preliminary evaluation of the ISG Viewing Wand, a frameless image-directed surgical system that is based on the rapid reformat and accurate three-dimensional reconstruction capability of parallel processor-based computer technology. We have compared the first 36 cases carried out with the system in the Frenchay Neurosurgery Department with a retrospective analysis of the previous 36 cases carried out using the Leksell G frame...
