Couldwell, William T. | Review by Oren N. Gottfried, M.D. and William T. Couldwell, M.D., Ph.D for Neurosurgery Journal Club. (Yadav JS, Wholey MH, Kuntz RE, et al: Protected carotid-artery stenting versus endarterectomy in high-risk patients.) | This is an important study that helps further define a role for carotid stenting as a therapeutic option for atherosclerotic carotid disease. There is a need for a larger-scale multi-centered trial with increased numbers patients and longer follow-up to identify appropriate patients for either endar... | Carotid Stenosis; Endarterectomy, Carotid; Stents | 2005-01-07 |

Jaeckle, Kurt A.; Digre, Kathleen B.; Jones, Christopher R.; Bailey, Peter L. | Central neurogenic hyperventilation: pharmacologic intervention with morphine sulfate and correlative analysis of respiratory, sleep, and ocular motor dysfunction. | Central neurogenic hyperventilation (CNH), for which there is no effective therapy, can eventually result in respiratory fatigue and death. This report describes a patient with CNH due to a brainstem anaplastic astrocytoma who also exhibited disturbances of sleep and ocular motor function.

Couldwell, William T. | Posterolateral approach for decompression with anterior and posterior fusion: a less invasive surgical technique for stabilization of the thoracic spine | The goals of surgery in unstable thoracic fractures or tumors involving the thoracic spine are neural decompression, correction of deformity, and stabilization. Several different approaches can be used to achieve these goals. The anterior, combined anterior and posterior, and more recently thoraco... | Decompression; Thoracic spine; Posterolateral approach | 1998 |

Couldwell, William T. | Prognostic variables in surgery for skull base meningiomas | The authors have retrospectively analyzed selected surgical and pathological observations made among a group of 20 patients harboring recurrent cranial base meningiomas in an attempt to reveal which factors may be important in predicting tumor recurrence. This cohort was compared with a group of 3... | Skull base; Prognostic factor; Recurrence | 1997 |

Schmidt, Meic H. | Cervical spine deformity associated with resection of spinal cord tumors | Postoperative sagittal-plane cervical spine deformities are a concern when laminectomy is performed for tumor resection in the spinal cord. These deformities appear to occur more commonly after resection of intramedullary spinal cord lesions, compared with laminectomy for stenosis caused by degener... | Kyphosis; Cervical deformity; Intramedullary tumor; Laminectomy; Children | 2006 |

Couldwell, William T. | Surgical approaches to petroclival meningiomas part I: upper and midclival approaches | Strictly considered, petroclival meningiomas represent only a percentage of the 10% of all intracranial meningiomas that reside in the posterior fossa. Although not statistically frequent, with their location in proximity to cranial nerves, the basilar artery and its perforating branches, and t... | Petroclival meningiomas; Petroclivus; Surgical approach; Upper clivus; Midclivus | 1994 |

Kestle, John R. W. | Determining the best cerebrospinal fluid shunt valve design: the pediatric valve design trial | Myriad cerebrospinal fluid shunt valve designs are available (17, IS). None has ever been shown to be superior to another, although claims by neurosurgeons and shunt manufacturers of the merits of particular designs are numerous. Such is the case with two recent shunt valve designs, the Orbis-Sigm... | Pediatric valve design; Shunt valves | 1996 |

Dailey, Andrew T. | Pathophysiology of oral pharyngeal apraxia and mutism following posterior fossa tumor resection in children | Mutism following posterior fossa tumor resection in pediatric patients has been previously recognized, although its pathophysiology remains unclear. A review of the available literature reveals 33 individuals with this condition, with only a few adults documented in the population. All of these pati... | Vermis; Posterior fossa tumor; Pediatric patients | 1995 |

Kestle, John R. W. | Response to editorial: summer shunting | We thank Dr. Scott for his review and comments about our report of shunt surgery complications in the summer. He makes two very good points. Clearly, different databases are suited for different purposes, and the NIS database used in the study by Smith and colleagues is well suited to evaluating t... | | 2006 |

Couldwell, William T.; Apfelbaum, Ronald I. | Variations on the standard transsphenoidal approach to the sellar region, with emphasis on the extended approaches and parasellar approaches: surgical experience in 105 cases | The traditional boundaries of the transsphenoidal approach may be expanded to include the region from the cribriform plate of the anterior cranial base to the inferior clivus in the anteroposterior plane, and laterally to expose the cavernous cranial nerves and the optic canal. We review our combin... | Transsphenoidal surgery; Chordoma; Craniopharyngioma; Intracranial neoplasm; Meningioma; Pituitary adenoma; Sella turcica; Transsphenoidal craniotomy | 2004 |

Kestle, John R. W. | Reduction of hemorrhage risk after stereotactic radiosurgery for cavernous malformations | The benefits of radiosurgery for cavernous malformations are difficult to assess because of the unclear natural history of this vascular lesion, the inability to image malformation vessels, and the lack of an imaging technique that defines "cure." The authors selected for radiosurgery 47 patients w... | Cavernous malformation; Gamma knife; Stereotactic radiosurgery | 1995 |

Couldwell, William T. | Role of CCM1 loss-of-function-induced endothelial-to-mesenchymal transition in the development of cavernous malformations | Cerebral cavernous malformations (CCM) occur in two variants: sporadic and familial. Mutations in three genes-CCM1, CCM2, and CCM3-play a role in both subtypes, with mouse models showing the development of multiple cavernous malformations in animals with loss of function in any of these three genes.... | | 2013-01-01 |

Kestle, John R. W. | Abdominal binders | Sklar and colleagues2 describe their experience managing "over-shunting headaches" with an abdominal binder. Seventy children with over-shunting headaches complied with application of a binder for about 1 month. In 61 patients (87%), the headaches "greatly improved or went away." This headache relie... | | 2012-01-01 |

Schmidt, Meic H. | Spinal extradural arachnoid cysts: clinical, radiological, and surgical features | Extradural arachnoid cysts in the spine are rare and are seldom a cause of spinal cord compression. They are thought to arise from congenital defects in the dura mater, and they almost always communicate with the intrathecal subarachnoid space through a small defect in the dura. The mainstay of trea... | Spinal extradural arachnoid cyst; Spinal meningeal cyst; Neurogenic claudication | 2007 |

Schmidt, Meic H. | Minimally invasive thoracoscopic resection of paraspinal neurogenic tumors: technical case report | OBJECTIVE: The posterior mediastinum is a common location for benign neurogenic tumors. They are frequently asymptomatic but can present with local compressive or neurological symptoms. METHODS: Thoracoscopy is used increasingly over posterolateral thoracotomy for the removal of these lesions. RES... | | 2008-01-01 |

Couldwell, William T.; Schmidt, Richard H. | Ruptured intracranial dermoid cysts: clinical, radiographic, and surgical features | Intracranial dermoid cysts are pathologically characterized by a thick, stratified squamous epithelium cyst wall containing dermal elements. Rupture into the subarachnoid spaces and ventricles is extremely rare.
