Endoscopic endonasal transoculomotor triangle approach for adenomas invading the parapeduncular space: surgical anatomy, technical nuances, and case series.
Pituitary adenomas may extend into the parapeduncular space by invading through the roof of the cavernous sinus. Currently, a transcranial approach is the preferred choice, with or without the combination of an endonasal approach. In this paper the authors present a novel surgical approach that takes advantage of the natural corridor provided by the tumor to further open the oculomotor triangle and resect tumor extension into the parapeduncular space. ⋯ The endoscopic endonasal transoculomotor approach is an original alternative for removal of tumor extension into the parapeduncular space in a single procedure. The surgical corridor is increased by opening the dura of the oculomotor triangle and by working below and lateral to the cisternal segment of the oculomotor nerve.

A useful diagnostic method to reduce the in-hospital time delay for mechanical thrombectomy: volume perfusion computed tomography with added vessel reconstruction.
Volume perfusion CT (VPCT) with added CT angiography (CTA)-like reconstruction from VPCT source data (VPCTA) can reveal multiple intracranial parameters. The authors examined the usefulness of VPCTA in terms of reducing the in-hospital time delay for mechanical thrombectomy. ⋯ Compared with CTA, VPCTA significantly reduced the in-hospital time delay during the prethrombectomy period.

Barriers to participation in global surgery academic collaborations, and possible solutions: a qualitative study.
There is a global lack of access to surgical care, and this issue disproportionately affects those in low- and middle-income countries. Global surgery academic collaborations (GSACs) between surgeons in high-income countries and those in low- and middle-income countries are one possible sustainable way to address the global surgical need. The objective of this study was to examine the barriers to participation in GSACs and to suggest ways to increase involvement. ⋯ Steps can be taken to address some of these barriers and to increase the involvement of surgeons from high-income countries in GSACs. This could lead to a necessary scale-up of global surgery efforts that may help increase worldwide access to surgical care.

ReviewAn estimation of global volume of surgically treatable epilepsy based on a systematic review and meta-analysis of epilepsy.
Epilepsy is one of the most common neurological disorders, yet its global surgical burden has yet to be characterized. The authors sought to compile the most current epidemiological data to quantify global prevalence and incidence, and estimate global surgically treatable epilepsy. Understanding regional and global epilepsy trends and potential surgical volume is crucial for future policy efforts and resource allocation. ⋯ Understanding of the global epilepsy burden has evolved as more regions have been studied. This up-to-date worldwide analysis provides the first estimate of surgical epilepsy volume and an updated comprehensive overview of current epidemiological trends. The disproportionate burden of epilepsy on low- and middle-income countries will require targeted diagnostic and treatment efforts to reduce the global disparities in care and cost. Quantifying global epilepsy provides the first step toward restructuring the allocation of healthcare resources as part of global healthcare system strengthening.
