The use of stents for revascularization is becoming the standard of care in many vascular territories. One of the concerns with angioplasty and stenting of atherosclerotic lesions are thromboembolic complications. In the last few years a number of protection devices (PDs) have been developed. This report reviews the current status of PDs during carotid artery stenting.

Surgery for acoustic tumors has improved dramatically during the last few decades with the application of microsurgical techniques. Surgical results no longer include mortality as a significant variable, and outcome is measured in terms of preservation of the facial nerve and hearing. Patients with small tumors and intact hearing have the best chances for preservation of both the facial and cochlear nerves, whereas patients with moderately sized tumors still have satisfactory neurological outcomes. For hearing preservation in patients with small and medium tumors, the posterior fossa and middle fossa approaches yield good results. In cases of large tumors with no ser-viceable hearing, the translabyrinthine, the transotic, and the suboccipital retrosig-moid approach yield comparable results. Selection of procedures for removal of acoustic tumors requires consideration of the patient’s neurological function and general condition, the topography of the tumor, and the surgeon’s expertise.

This article provides a brief description of the current knowledge of meningioma tumorigenesis and biology. Meningioma grade, subtyping, histology, and MIB-1 labeling index are discussed in relationship to tumor behavior and recurrence prediction. Chromosomal abnormalities associated with meningioma development are discussed with an emphasis on chromosome 22 and the neurofibromatosis type 2 gene. The current knowledge of prognostic features of 1p deletions is outlined. The role of sex hormones in meningioma growth and development is also discussed and summarized. To date, treatment regimens based on inhibiting hormonally mediated meningioma growth have been disap-pointing. Research concerning growth factors and peptide hormones that have been implicated in meningioma tumorigenesis is discussed. It is hoped that further understanding of the biology of meningioma development, growth, and angiogenesis will lead to new successful treatments for refractory meningiomas.

Meningiomas of the foramen magnum are considered a separate group of tumors because of their clinical presentation, surgical considerations, and clinical outcome. These are rare tumors that account for 1.8 to 3.2% of all meningiomas and 6 to 7% of all posterior fossa meningiomas. Many publications have appeared over the last two decades highlighting the virtues of an increasingly lateral approach to tumors at the anterior aspect of the foramen magnum. Selection of a lateral approach over a more conventional suboccipital approach and management of the occipital condyle and the vertebral artery are issues that are still debated. We present the clinical presentation, radiological findings, an anatomical description, and the principles of the surgical technique we use for these tumors. The results for 18 patients with anterior and anterolateral foramen magnum meningiomas treated surgically by the senior author are presented as well.

A nterior rami of the spinal nerve roots from the C5 to the T1 levels of the spinal cord come together in the posterior triangle of the neck to form the brachial plexus. The subdivisions of the brachial plexus, including the roots, trunks, divisions, cords, and nerves, traverse the lateral extent of the posterior triangle of the neck, the upper thorax, the axilla, and the upper extremity. The brachial plexus surgeon must be familiar with not only the anatomy of the neck, thorax, shoulder, and arm, but also with the surgical approaches that provide optimal exposure to both the pathology and the neural elements.
