The surgical role of C1 nerve root identification for the disconnection of the spinal dural arteriovenous fistula at the craniocervical junction: a single center restrospective experience.

This study aims to discuss the identification of the C1 nerve root as an effective surgical approach to successfully locate the shunting point of craniocervical junction spinal dural arteriovenous fistula (CCJ-SDAVF) intraoperatively. This study included all patients with CCJ-SDAVF who underwent surgical treatment using the far-lateral transcondylar approach at a single institution from January 2017 to June 2023. Data on patient demographics, clinical and angiographic characteristics of CCJ-SDAVF, surgical details, and treatment outcomes were collected. Follow-up assessments were conducted for all patients until December 31, 2023. The study included a total of 7 patients, comprising 5 men(71.4%) and 2 women (28.6%), with an average age of 57.6 years. Among them, 4 patients (57.1%) developed diffuse subarachnoid hemorrhage(SAH), while 2 patients (28.6%) experienced progressive cervical myelopathy. The shunting points of all CCJ-SDAVFs, which exhibited engorged veins, were identified next to the C1 root. Complete obliteration of CCJ-SDAVFs was successfully achieved in all patients, as confirmed by postoperative angiography one month later. No recurrent CCJ-SDAVFs were observed two years after the operation. Among the patients, 5 (71.4%) experienced good functional recovery, as indicated by an mRS score ranging from 0 to 1, while the remaining 2 patients (28.6%) showed incomplete functional recovery. The surgical interruption of CCJ-SDAVFs is the preferred treatment option, given its high obliteration rate and favorable functional recovery outcomes. We advocate the identification of C1 spinal nerve root as a crucial surgical step to identify the shunting points of CCJ- SDAVFs.

An Overview of Global Neurosurgery.

Until recently, surgery had been passed over in the domain of global health, historically being described as "the neglected stepchild of global health." Knowledge of the existing global disparities in neurosurgical care has led to neurosurgery capacity-building efforts especially in low-income and middle-income countries. While many global collaborative projects are currently undertaken with philanthropic support, sustainability and scalability are not likely without governmental adoption of neurosurgery-inclusive national surgical plans. Momentum grows for the global neurosurgery community to develop a global neurosurgery action plan outlining goals, a guiding framework, an execution plan, and indicators for monitoring and evaluation.

Education and Training in Global Neurosurgery: Current State and Path Toward a Uniform Curriculum.

Education is a sustainable long-term measure to address the global burden of neurosurgical disease. Neurosurgery residencies in high-income countries are accredited by a regional governing body and incorporate various educational activities. Few opportunities for training may be present in low-income and middle-income countries due to a lack of neurosurgery residency programs, tuition, and health care workforce reductions. Core components of a neurosurgical training curriculum include operative room experience, clinical rounds, managing inpatients, and educational conferences. A gold standard for neurosurgical education is essential for creating comprehensive training experience, though training must be contextually appropriate.

Establishing Microsurgery Skills Laboratories in Low- and Middle-income Countries with Integrated Remote Teaching: A Novel Approach.

Microneurosurgical techniques remain crucial for managing neurosurgical diseases, especially in low- and middle-income countries (LMICs) where other advanced treatment modalities are not available. The global distribution of these techniques is uneven due to disparities in infrastructure, equipment, and training. Medical professionals from LMICs face barriers in reaching training centers in high-income countries, as well as in accessing microsurgical techniques. To address these disparities in microsurgery training, we offer free and accessible microsurgery training model by combining the donations of microsurgery kits with a comprehensive support system that includes live-streamed, offline, and in-person assistance within LMICs.

Global Partnerships in Neurosurgery: Mapping the Need.

The field of global neurosurgery seeks to improve access to neurosurgery and reduce health disparities worldwide. This process depends on intensive collaboration between partners in high-income and low-to-middle income country (LMIC) settings. Several such collaborations have propelled global neurosurgery forward, and long-standing partnerships in particular have brought subspecialty care and training to new locations. Recently, there have been more reports of collaborations between LMICs themselves. In this narrative study, we summarize the state of collaboration in global neurosurgery and discuss how the field is likely to change moving forward.

Continuing Education for Global Neurosurgery Graduates: Visiting Surgeons, Skills Teaching, Bootcamps, and Twinning Programs.

Neurosurgeons require post-graduate training to deliver safe, effective, and evidence-based care; to continually improve and adapt their methods through assessing the effect of their care and patient outcomes; and to train the future neurosurgeons of tomorrow to surpass current standards of care. We describe methods used by global collaborations to address these training needs on a worldwide scale, their risks, and their perceived benefits.

Nongovernmental Organizations in Global Neurosurgery: Foundation for International Education in Neurological Surgery and Solidarity Bridge.

Health care disparities between high-income countries (HICs) and low- and middle-income countries (LMICs) are well established. The focus of the surgical aspect of health was identified in the early twenty-first century, and efforts to provide safe surgical intervention require the shift of resources from HICs to LMICs with specialized surgeons, anesthesiologists, and equipment. This intervention may make a difference on the short run; however, to achieve a long-term self-sustaining surgical service in the region of need, education and training of local physicians is key.

Practical pearls for management of cranial injury in the developing world.

Traumatic brain injury (TBI) remains a leading cause of morbidity and mortality, with approximately 69 million individuals affected globally each year, particularly in low- and middle-income countries (LMICs) where neurosurgical resources are limited. The neurocognitive consequences of TBI range from life-threatening conditions to more subtle impairments such as cognitive deficits, impulsivity, and behavioral changes, significantly impacting patients' reintegration into society. LMICs bear about 70% of the global trauma burden, with causes of TBI differing from high-income countries (HICs). The lack of equitable neurosurgical care in LMICs exacerbates these challenges. Improving TBI care in LMICs requires targeted resource allocation, neurotrauma registries, increased education, and multidisciplinary approaches within trauma centers. Reports from successful neurotrauma initiatives in low-resource settings provide valuable insights into safe, adaptable strategies for managing TBI when "gold standard" protocols are unfeasible. This review discusses common TBI scenarios in LMICs, highlighting key epidemiological factors, diagnostic challenges, and surgical techniques applicable to resource-limited settings. Specific cases, including epidural hematoma, subdural hematoma, subarachnoid hemorrhage, and cerebrospinal fluid leaks, are explored to provide actionable insights for improving neurosurgical outcomes in LMICs.
