51 Schmidt, Meic H.Minimally invasive thoracoscopic approach for anterior decompression and stabilization of metastatic spine diseaseObject. The choices available in the management of metastatic spine disease are complex, and the role of surgical therapy is increasing. Recent studies have indicated that patients treated with direct surgical decompression and stabilization before radiation have better functional outcomes than thos...Metastatic spine disease; Minimally invasive surgery; Spinal cord decompression2008
52 Dailey, Andrew T.Guidelines for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 17: bone growth stimulators and lumbar fusionTreatment Standards.

54 Kestle, John R. W.; Brockmeyer, Douglas LeeOptic pathway gliomas: a reviewOptic pathway gliomas represent approximately 3-5% of childhood intracranial tumors. They usually occur in children during the first decade of life and are seen in 11-30% of patients with neurofibromatosis Type 1 (NF1). Although these tumors are typically low-grade gliomas, the clinical course and n...Optic pathway glioma; Hypothalamus glioma; Neurofibromatosis Type 12007

58 Couldwell, William T.; Osborne, Anne G.Hypertrophic olivary degeneration after surgical removal of cavernous malformations of the brain stem: report of four cases and review of the literatureBackground: Hypertrophic olivary degeneration (HOD) is a pathological phenomenon that occurs after injury to the dentato-olivary pathway. Its hallmarks include hypertrophy of the olive with increased T2 signal intensity on magnetic resonance imaging, and often manifests with palatal tremor and osci...Hypertrophic olivary degeneration; Surgery; Cavernous malformation; Brainstem2008
59 Schmidt, Meic H.; Schmidt, Richard H.Nerve sheath tumors involving the sacrumNerve sheath tumors that involve the sacrum are rare. Delayed presentation is common because of their slow-growing nature, the permissive surrounding anatomical environment, and nonspecific symptoms. Consequently, these tumors are usually of considerable size at the time of diagnosis. The authors di...Nerve sheath tumor; Schwannoma2003
60 Dailey, Andrew T.Guidelines for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 15: electrophysiological monitoring and lumbar fusionStandards.

62 Couldwell, William T.; Gottfried, Oren N.Distal ventriculoperitoneal shunt failure secondary to clostridium difficile colitisDistal ventriculoperitoneal shunt obstruction is typically associated with cerebrospinal fluid (CSF) infection, fluid pseudocysts, bowel obstruction, bowel perforation, or improper shunt placement in the abdomen. We describe a unique etiology for distal shunt obstruction secondary to Clostridium di...2005-01-01
63 Couldwell, William T.; Gillespie, David L.; Jensen, Randy L.Comparison of the cell lines used in meningoma researchBackground: Immortal cell lines and cell lines derived from operative specimens transplanted into animal models are used in meningioma research. We address two criticisms of the mouse xenograft flank tumor model: Why are tumor induction rates derived from operative specimens low and inconsistent? Ar...CH-157 MN; IOMM-Lee; Meningioma; Xenograft Mouse Model; Flank tumors2008
64 Couldwell, William T.Experience with use of extended length peritoneal shunt cathetersThe placement of a ventriculoperitoneal (VP) shunt is the current treatment of choice for diversion of cerebrospinal fluid associated with hydrocephalus. Although there are a host of reported potential abdominal complications related to the procedure, they are notably uncommon. The authors report t...1996
65 Couldwell, William T.Far-lateral transcondylar approach: surgical technique and its application in neurenteric cysts of the cervicomedullary junctionNeurenteric cysts are rare benign lesions of the central nervous system that are lined by endodermal cell-derived epithelium. Although they occur mostly in the spine, they can occur intracranially, most often in the posterior fossa. Neurenteric cysts that are located in the anterior cervicomedullary...2005
66 Couldwell, William T.The frontotemporal (Pterional) approach: an historical perspectiveThe frontotemporal, so-called "pterional" approach has evolved with the contribution of many neurosurgeons over the past century. It has stood the test of time and been the most commonly used transcranial approach in neurosurgery. In its current form, drilling the sphenoid wing as far down as the su...2012-01-01
67 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 3: Assessment of economic outcomeA comprehensive economic analysis generally involves the calculation of indirect and direct health costs from a societal perspective as opposed to simply reporting costs from a hospital or payer perspective. Hospital charges for a surgical procedure must be converted to cost data when performing a c...2014-01-01
68 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 4: Radiographic assessment of fusion statusThe ability to identify a successful arthrodesis is an essential element in the management of patients undergoing lumbar fusion procedures. The hypothetical gold standard of intraoperative exploration to identify, under direct observation, a solid arthrodesis is an impractical alternative. Therefore...2014-01-01
69 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 9: Lumbar fusion for stenosis with spondylolisthesisPatients presenting with stenosis associated with a spondylolisthesis will often describe signs and symptoms consistent with neurogenic claudication, radiculopathy, and/or low-back pain. The primary objective of surgery, when deemed appropriate, is to decompress the neural elements. As a result of t...2014-01-01
70 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 7: Lumbar fusion for intractable low-back pain without stenosis or spondylolisthesisEstablishing an appropriate treatment strategy for patients presenting with low-back pain, in the absence of stenosis or spondylolisthesis, remains a controversial subject. Inherent to this situation is often an inability to adequately identify the source of low-back pain to justify various treatmen...2014-01-01
71 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 2: Assessment of functional outcome following lumbar fusionAssessment of functional patient-reported outcome following lumbar spinal fusion continues to be essential for comparing the effectiveness of different treatments for patients presenting with degenerative disease of the lumbar spine. When assessing functional outcome in patients being treated with l...2014-01-01
72 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 8: Lumbar fusion for disc herniation and radiculopathyPatients suffering from a lumbar herniated disc will typically present with signs and symptoms consistent with radiculopathy. They may also have low-back pain, however, and the source of this pain is less certain, as it may be from the degenerative process that led to the herniation. The surgical al...2014-01-01
73 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 6: Discography for patient selectionIdentifying the etiology of pain for patients suffering from chronic low-back pain remains problematic. Noninvasive imaging modalities, used in isolation, have not consistently provided sufficient evidence to support performance of a lumbar fusion. Provocative testing has been used as an adjunct in ...2014-01-01
74 Couldwell, William T.Expanding neurosurgeryThe history of medicine is replete with innovations in neurosurgery that have spurred further developments across the medical spectrum.

75 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 16: Bone graft extenders and substitutes as an adjunct for lumbar fusionIn an attempt to enhance the potential to achieve a solid arthrodesis and avoid the morbidity of harvesting autologous iliac crest bone (AICB) for a lumbar fusion, numerous alternatives have been investigated. The use of these fusion adjuncts has become routine despite a lack of convincing evidence ...2014-01-01
