76 Couldwell, William T.History and evolution of transsphenoidal surgeryInitial attempts at transcranial approaches to the pituitary gland in the late 1800s and early 1900s resulted in a mortality rate that was generally considered prohibitive. Schloffer suggested the use of a transsphenoidal route as a safer, alternative approach to the sella turcica. He reported the f...Neurosurgical history; Transsphenoidal surgery; Pituitary tumor2001
77 Couldwell, William T.False-negative magnetic resonance angiography with extracranial internal carotid artery stenosis: a report of two cases and review of the literatureMagnetic resonance angiography (MRA) is increasingly used as a noninvasive means to assess internal carotid artery (ICA) stenosis. When used alone, however, MRA may not be sufficiently accurate in certain settings to determine whether ICA disease meets surgical criteria. Although MRA has been recogn...Internal carotid artery stenosis; Magnetic resonance angiography2005
78 Couldwell, William T.Strategies for the management of nonsecreting pituitary adenomasThe two objectives of treating pituitary tumors are: (1) relief of signs and symptoms attributable to mass effect, and (2) correction of hypo - or hypersecretion of adenohypophyseal hormones.7 When nonsecreting tumors are specifically considered, correction of endocrine abnormalities may be of les...Pituitary adenomas; Transsphenoidal surgery1991
79 Kestle, John R. W.Cost-effectiveness analysis of endoscopic third ventriculostomyOBJECTIVE: Endoscopic third ventriculostomy (ETV) is currently the principal alternative to cerebrospinal fluid shunt placement in the management of pediatric hydrocephalus.

87 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
88 Couldwell, William T.Surgical implications of magnetic resonance-enhanced duraTHE PURPOSE OF this study was to assess tissue changes responsible for dural enhancement on magnetic resonance imaging (MRI) and its clinical implications.
