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...

OBJECT: Bibliometrics is defined as the study of statistical and mathematical methods used to quantitatively analyze scientific literature. The application of bibliometrics in neurosurgery is in its infancy. The authors calculate a number of publication productivity measures for almost all academic neurosurgeons and departments within the US. METHODS: The h-index, g-index, m-quotient, and contemporary h-index (hc-index) were calculated for 1225 academic neurosurgeons in 99 (of 101) programs listed by the Accreditation Council for Graduate Medical Education in January 2013...

OBJECTIVE: The practice of neurosurgery requires fundamental knowledge base. Residency training programs and continuing medical education courses are designed to teach relevant neurosurgical principles. Nevertheless, knowledge gaps exist for neurosurgeons and may be different between cohorts of neurosurgeons. The Self-Assessment in Neurological Surgery (SANS) General Examination and Spine Examination are online educational tools for lifelong learning and maintenance of certification. This study examines the gaps in knowledge of spinal neurosurgeons and general neurosurgeons taking SANS...

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)...

Neurosurgeons, radiation oncologists, and, increasingly, other surgical specialists recognize that radiosurgery is an important tool for managing selected disorders throughout the body. The partnership between neurosurgeons and radiation oncologists has resulted in collaborative studies that have established the clinical benefits of radiosurgery. Today, however, a range of political and financial issues is straining this relationship and thereby undermining the practice of radiosurgery. Neurosurgeons and radiation oncologists recently restricted the definition of radiosurgery to include only cranial- and spine-focused radiation treatments...

First developed in the 1960s, interventional neuroradiology has vastly improved the management of patients with vascular diseases of the brain and spine, including vascular malformations and stroke. Gradually replacing open-skull neurosurgical approaches, endovascular occlusion of ruptured intracranial aneurysms has improved the post-bleed prognosis. With the increasing number of fortuitously discovered aneurysms, international randomized studies are being organized to determine whether preventive treatment is better than abstention...

Surgical robotics is one of the most dynamically advancing areas of biomedical engineering. In the past few decades, computer-integrated interventional medicine has gained significance internationally in the field of surgical procedures. More recently, mechatronic devices have been used for nephrectomy, cholecystectomy, as well as in orthopedics and radiosurgery. Estimates show that 70% of the radical prostatectomies were performed with the da Vinci robot in the United States last year. Robot-aided procedures offer remarkable advantages in neurosurgery both for the patient and the surgeon, making microsurgery and Minimally Invasive Surgery a reality, and even complete teleoperation accessible...

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...

Radiosurgery for brain tumors has been well established in the radiation oncology and neurosurgery fields. Radiosurgery of extracranial tumors such as those involving the spine is, however, still in the early stage because of difficulties in patient immobilization and organ motion. The authors describe an image-guided procedure for intensity-modulated spinal radiosurgery that was developed at Henry Ford Hospital.

Although surgeons in Austria, especially in Vienna, were counted among the leading specialists at the end of the 19th century, neurosurgery did not evolve as a distinct discipline before the turn of the century; achievements were episodic until Anton von Eiselsberg became an enthusiastic surgeon of the central nervous system at the beginning of the 20th century. On the threshold of modern microneurosurgery, he was succeeded in Vienna by Leopold Schönbauer and then by Herbert Kraus. Although Schönbauer kept a certain distance from neurosurgery before World War II, a special department of neurosurgery was founded at the University of Graz Medical Faculty in 1950...

The Henry Ford Hospital (HFH) was founded in 1915 as a philanthropic gift from Henry Ford, the automobile magnate and inventor of the Model T. The hospital and its organizational structure represented a nonsectarian facility that would provide care for all members of society. The system was patterned after the newest and most modern medical centers at the time in Europe, Canada, and the United States, including the German Krankenhauser, the Johns Hopkins Hospital, the Mayo Clinic, and the Peter Bent Brigham Hospital in Boston...

A prototype device called an extracranial stereotactic radiosurgery frame was used to deliver stereotactic radiosurgery, with a modified linear accelerator, to metastatic neoplasms in the cervical, thoracic, and lumbar regions in five patients. In all patients, the neoplasms had failed to respond to spinal cord tolerance doses delivered by standard external fractionated radiation therapy to a median dose of 45 Gy (range, 33-65 Gy/11-30 fractions). The tumors were treated with single-fraction stereotactic radiosurgery with the spinal stereotactic frame for immobilization, localization, and treatment...

Advances in the surgical management of central nervous system neoplasms have been reported in several areas including the skull base, the spine and the stereotaxic applications in neurosurgery. A national survey of patterns of care for brain tumor patients contributed data on 11,185 patients, 97% of whom underwent surgery. Stereotaxic-guided craniotomies are providing added accuracy and shortened operative time and length of hospitalization, while the stereotaxic implantation of I125 seeds for recurrent high grade glioma has resulted in prolongation of survival between 54 and 81 weeks...
