To describe a technique to approach the anterior inferior basal ganglia. ⋯ The approach described here is a novel alternative to transsylvian or supracarotid approaches to the anterior inferior basal ganglia and in this patient provided a well-tolerated surgical corridor that allowed complete resection of his cavernoma. We discuss several advantages and disadvantages of the various approaches to the anterior inferior basal ganglia.

Sphenoid wing region dural arteriovenous fistulas (DAVFs) are rare lesions that are typically fed by middle meningeal artery feeders and that drain via the sphenoparietal sinus or middle cerebral vein. We describe a unique case of a medial sphenoid wing fistula draining exclusively via the basal vein of Rosenthal. ⋯ Sphenoid wing DAVFs may drain via the deep venous system and have a complex arterial feeding network. Key features of the fistula, including deep venous drainage, presence of venous varices, and retrograde leptomeningeal venous drainage, make this an aggressive lesion with a high risk of rupture based on the available natural history data.

Contributing to medical practice in developing countries has become increasingly prevalent. Primary care and preventative health initiatives have been most visible, although attention has recently shifted to surgical disease, which represents a large burden in resource-poor settings. Typically dominated by individual efforts, there is now a more concerted approach, with surgical care being included in the comprehensive primary health care plan set by the World Health Organization. Although ethical dilemmas in international surgery have been discussed sporadically in the context of specific missions from the visiting surgeon/team perspective, we are missing a comprehensive evaluation of these issues in the literature. Here we have chosen to systematically categorize ethical issues confronted while teaching and operating in a developing country into 2 broad categories: venue (i.e., host) and visitor related. ⋯ This article provides a discussion written from visiting and host surgeon perspectives on diverse ethical challenges for which there is limited literature, including location selection, unmet needs at home, role of sponsors, and personal gain. In addition to candid discussion and a solutions-focused approach, the reader is provided with an "ethical checklist" for international surgical education, akin to the World Health Organization surgical safety checklist, to serve as a framework for the design of surgical missions that avoid ethical pitfalls.

The purpose of this study was to evaluate the efficacy and safety of gamma knife radiosurgery (GKRS) for the treatment of symptomatic brainstem intra-axial cavernous malformations (CMs) associated with high surgical morbidity. ⋯ GKRS seems to be relatively effective and safe for reducing the rebleeding rate of brainstem intra-axial CMs that have high surgical risk. Careful selection of a low marginal dose and an optimal radiosurgical technique are helpful to achieve good outcomes.

An increasing number of neurological surgeons have sought fellowship training in recent years, and previous analyses have suggested these practitioners are more likely to pursue an academic career. Scholarly productivity is a key component in academic advancement. ⋯ No significant difference existed between the mean h-index scores of neurological surgeons who completed fellowships and those who did not. However, when stratified by academic rank, a trend was observed showing greater mean h-index scores for those who completed fellowships. This trend persists across nearly all subspecialties. Overall, being a senior faculty member corresponds with a greater h-index score, regardless of whether a fellowship was completed.
