A variety of factors may affect surgical outcome in patients with cervical spondylotic myelopathy. The aim of this study is to determine these factors on the basis of preoperative radiological and clinical data. ⋯ It can be concluded that age and abnormal cervical curvature predict less postoperative neurological improvement. The presence of preoperative high signal intensity within the spinal cord may also reflect less neurological improvement.

Stereotactic radiosurgery is increasingly being used to treat hemangioblastomas, particularly those that are in surgically inaccessible locations or that are multiple, as is common in von Hippel-Lindau disease. The purpose of this study was to retrospectively evaluate the effectiveness of radiosurgery in the treatment of hemangioblastomas. ⋯ Although follow-up monitoring is limited, stereotactic radiosurgery provides a high likelihood of local control of hemangioblastomas and is an attractive alternative to multiple surgical procedures for patients with von Hippel-Lindau disease.

Before 1937, members of the Department of Surgery and Gynecology practiced emergency neurosurgery at the University of Virginia in the same fashion as in other hospitals in the United States. In 1937, Claude C. Coleman, Chairman of the Department of Neurosurgery at the Medical College of Virginia in Richmond, organized a Division of Neurosurgery as part of the Department of Surgery and Gynecology at the University of Virginia. ⋯ Laws, Jr., in 1992, Dheerendra Prasad in 1995, Gregory Helm in 1996, and Mark Shaffrey in 1997. Resident training has been a priority of the Department of Neurosurgery; many academic neurosurgeons were trained and practiced their specialty in the Department early in their careers. Sixty years after its foundation, the Department of Neurosurgery continues its commitment to patient care, research, and the "... instruction of those who come after us."

One of the largest contemporary neurosurgical experiences with hypothermic circulatory arrest was analyzed for trends in patient selection and clinical variables affecting outcome. ⋯ Current indications for hypothermic circulatory arrest include only giant and complex posterior circulation aneurysms that cannot be treated using conventional techniques or that recur after endovascular coiling. Surgical morbidity and mortality rates reflect the increasing complexity of the aneurysms treated but are still more favorable than the natural history of these lesions. This experience demonstrates that management in specialized neurovascular centers can minimize the morbidity associated with circulatory arrest so that it remains a viable treatment option for complex posterior circulation aneurysms.

To demonstrate that microvascular decompression of the left medulla oblongata is a safe and effective modality for treating elevated blood pressure in patients with severe medically refractory "essential" hypertension (HTN). ⋯ Microvascular decompression of the left rostral ventrolateral medulla oblongata may be an effective treatment modality for patients suffering from severe HTN and/or autonomic dysreflexia refractory to medical management.
