Couldwell, William T. | Comment on Kitano, M., et al.: Subdural patch graft technique for watertight closure of large dural defects in extended transsphenoidal surgery | Ahn and Kim demonstrate a suturing technique to close dural defects after transsphenoidal and extended transsphenoidal approaches. The technique entails a specifically designed forceps to cinch the knot down in the depths of the field. The Author's used the technique in 21 consecutive patients (16 e... | Transsphenoidal surgery; CSF leaks | 2009 |

Kestle, John R. W. | Comparison between magnetic resonance imaging and computed tomography for stereotactic coordinate determination | The spatial accuracy of magnetic resonance imaging (MRI) has not been established for stereotactic surgery. Magnetic susceptibility artifacts may lead to anatomical distortion and inaccurate stereotactic MRI coordinates, especially when targets are in regions of the brain out of the center of the ma... | Computed tomography; Stereotactic coordinates; Stereotactic surgery | 1992 |

Kestle, John R. W.; Walker, Marion L. | Noncommunicating spinal extradural arachnoid cyst causing spinal cord compression in a child | Extradural arachnoid cysts in the spine are relatively uncommon causes of spinal cord compression in the pediatric population that are thought to arise from congenital defects in the dura mater. Most reports describe such cysts communicating with the intrathecal subarachnoid space through a small de... | | 2006 |

Dailey, Andrew T. | Diagnosis and treatment of craniocervical dislocation in a series of 17 consecutive survivors during an 8-year period | Object. Craniocervical dissociation (CCD) is a highly unstable and usually fatal injury resulting from osseoligamentous disruption between the occiput and C-2. The purpose of this study was to elucidate systematic factors associated with delays in diagnosing and treating this life-threatening condit... | Spinal cord injury; Craniocervical dislocation; Atlantooccipital joint; Atlantoaxial joint; Tetraplegia; CCJ; CCD | 2006 |

Couldwell, William T. | Protein kinase C inhibitors suppress cell growth in established and low-passage glioma cell lines. a comparison between staurosporine and tamoxifen | WE HAVE PREVIOUSLY demonstrated that the proliferation of established human glioma cell lines correlated with protein kinase C (PKC) activity and that a relatively selective PKC inhibitor, staurosporine, inhibits glioma cell proliferation. The purpose of this study was to determine whether low-passa... | Staurosporin; Tamoxifen; Protein kinase C; Glioma; Brain neoplasm; Glioma cell lines | 1993 |
