Kestle, John R. W.; Brockmeyer, Douglas Lee | Complications of intracranial pressure monitoring in children with head trauma | Object. Intracranial pressure (ICP) monitoring has become routine in the management of patients with traumatic brain injury (TBI). Many surgeons prefer to use external ventricular drains (EVDs) over fiberoptic monitors to measure ICP because of the added benefit of cerebrospinal fluid drainage.

W.; MacDonald, Joel D.; Couldwell, William T. | Efficacy of multiple intraarterial papaverine infusions for improvement in cerebral circulation time in patients with recurrent cerebral vasospasm | Object. Cerebral vasospasm that is caused by aneurysmal subarachnoid hemorrhage and that is refractory to maximal medical management can be treated with selective intraarterial papaverine infusions. The effects of single papaverine treatments on cerebral circulation time are well known. The purpose ... | Cerebral vasospasm; Intraarterial papaverine infusions | 2004 |

Kestle, John R. W.; Townsend, Jeannette J.; Brockmeyer, Douglas Lee | Juvenile pilocytic astrocytoma of the brainstem in children | Object. In reports involving the operative treatment of brainstem tumors, multiple histological types are often grouped together. To determine prognosis after resection, histology-specific data may be helpful. Methods. Twenty-eight patients with juvenile pilocytic astrocytoma (JPA) of the brainste... | Juvenile pilocytic astrocytoma; JPA; Brainstem tumors; Resection | 2004 |

Kestle, John R. W.; MacDonald, Joel D.; Schmidt, Richard H. | Marked reduction of cerebral vasospasm with lumbar drainage of cerebrospinal fluid after subarachnoid hemorrhage | Object. Cerebral vasospasm after subarachnoid hemorrhage (SAH) continues to be a major source of morbidity in patients despite significant clinical and basic science research. Efforts to prevent vasospasm by removing spasmogens from the subarachnoid space have produced mixed results. The authors hyp... | Cerebral vasospasm; Lumbar drainage | 2004 |

Couldwell, William T. | Medical and surgical management of microprolactinoma | A recent report by Colao et al. [1] indicates that a significant proportion of patients harboring prolactinomas treated with cabergoline will have persistence of remission of hyperprolactinemia following withdrawal of the drug. The prolactin and tumor control rates in the study suggest that medical ... | Microprolactinoma; Prolactinoma; Cabergolene | 2004 |

Couldwell, William T. | Neurosurgical implications of allergic fungal sinusitis | Object. Allergic fungal sinusitis (AFS) is a form of paranasal mycosis that often involves bone destruction and extension into the orbit and anterior skull base. Treatment consists of surgical extirpation and a course of corticosteroids. Despite frequent intracranial involvement, AFS is rarely repor... | 2004 | |

Couldwell, William T.; Orlandi, Richard R.; Apfelbaum, Ronald I. | Novel closure technique for the endonasal transsphenoidal approach: Technical note | Transsphenoidal microsurgery has been the standard approach to sellar lesions since the repopularization of the technique with modifications by Dott, Guiot, and Hardy. The endonasal transseptal transsphenoidal approach, as introduced by Hirsch, is still commonly used by pituitary surgeons to remove ... | 2004 | |

Couldwell, William T. | Porous polyethylene implant for cranioplasty and skull base reconstruction | Object. Cranial reconstruction after skull base surgery is important for restoration of function and cosmesis. The authors describe their experience with the Medpor porous polyethylene implant for cosmetic cranioplasty and reconstruction after skull base surgery. Methods. Medpor, a biocompatible i... | 2004 | |

Schmidt, Meic H. | Role of thoracoscopic spinal surgery in the management of pyogenic vertebral osteomyelitis | Study Design. Case report, operative technique. Objectives. Vertebral osteomyelitis is frequently associated with elderly and debilitated patients who have significant medical comorbidities. If surgical debridement is contemplated, an open anterior approach like a thoracotomy can be associated with... | Thoracoscopic spinal surgery; Pyogenic vertebral osteomyelitis | 2004 |

Dailey, Andrew T. | Sciatic nerve sarcoidosis: utility of magnetic resonance peripheral nerve imaging and treatment with radiation therapy | Sarcoidosis may involve both the central and peripheral nervous system, although peripheral nerve manifestations are usually seen late in the disease. In this report, the authors describe a case of sarcoidosis in a 22-year-old woman who presented with a foot drop. Although results of conventional lu... | Peripheral nerve imaging; Radiation therapy | 2004 |
