Few studies have attempted to make a direct comparison of the risk of visual impairment following extradural anterior clinoidectomy (EAC) with and without the use of a power drill. To evaluate postoperative visual outcomes between groups of patients with paraclinoid carotid artery aneurysms (PCAAs) who underwent surgical clipping with and without the use of a power drill during EAC. Between January 2010 and November 2019, 90 patients, 7 with ruptured and 83 with unruptured PCAAs, underwent clipping surgery at our hospital. The authors retrospectively analyzed postoperative visual complications from the medical records of these patients. Among the 85 patients (excluding 3 patients with disturbance of consciousness caused by subarachnoid hemorrhage and 2 patients with preoperative visual disturbance) evaluated, EAC was conducted using a power drill in 64 patients and using a microrongeur in 21 patients. Permanent postoperative visual impairment developed in 14 (21.9%) patients in the drill group: 9 patients had ipsilateral lower nasal quadrant hemianopsia (ILNQH) and 5 patients had ipsilateral visual acuity reduction. Transient ILNQH developed in only 1 patient in the no-drill group. The incidence of permanent postoperative visual impairments was significantly lower in the no-drill group than in the drill group (P = .020). Seventeen (26.6%) patients developed transient oculomotor nerve palsy in the drill group, while no patients developed oculomotor nerve palsy in the no-drill group. EAC using a microrongeur versus a power drill significantly improved visual outcomes after clipping surgery for PCAAs.

To the Editor: We read with great interest the article published by Louis et al1 entitled “Impact of Neurosurgical Consultation With 360-Degree Virtual Reality Technology on Patient Engagement and Satisfaction,” where the authors propose the use of the technological tool of 360◦ virtual reality, which offers a didactic vision of the brain’s anatomic structures, as well as a reconstruction of the procedures to be performed, promoting the communication and perception of neurosurgical pathology, as well as patient satisfaction by improving their understanding of the dynamics of their disease. The offered model from the use of imaging studies (magnetic resonance imaging and computed tomography imaging), where high-resolution images are obtained, also allows patients and relatives to be educated about other associated entities with a high burden of disease, such as hypertension, type 2 diabetes mellitus, dyslipidemia, and heart disease, which negatively impact on cerebrovascular integrity. Thus, better adherence to the treatment can be obtained because the magnitude of such pathological conditions is recognized. We are very grateful to the authors1 for providing this valuable evidence, which should be taken and replicated in all regions of the world, not only focusing on the neurosurgical disease but other specialties. However, the most surprising fact about this model is that it can simulate real-time treatments, showing the interactions between the surgical instruments and the anatomic structures involved.1 Besides, it is a noninvasive intervention with immediate results, which could be included in the future, as screening for the early detection of pathologies according to risk factors. This instrument has also been used to reduce the anxiety produced by certain interventions, finding positive results, when patients argue that understanding their disease allows to assimilate the diagnosis, prognosis, and decreased fear of side and/or adverse effects.2 It has been found that patients with dementia of varying degrees improve their cognitive function by participating in virtual reality activities,3 so it can also be considered as a preventive measure to prolong neurological integrity, promote the level of education in those with no basic or higher education, and encourage the development of new life skills, to maintain or increase the functional capacity of older adults. On the other hand, virtual reality is a very effective technique to optimize education and surgical planning.4 It is a fundamental tool that helps to distinguish difficult management cases, to evaluate possible intraoperative alternatives. Besides, it can be used during the training of medical students, who are looking for a surgical specialty. Despite the evidence supporting such relevance in the academic and clinical fields, its use in the aforementioned scenarios has not yet been implemented globally.

Social network analysis of bibliometric data evaluates the relationships between the articles, authors, and themes of a research niche. The network can be visualized as maps composed of nodes and links. This study aimed to identify and evaluate the relationships between articles, authors, and keywords in global neurosurgery. The authors searched global neurosurgery articles on the Web of Science database from inception to June 18, 2020. The 50 most cited articles were selected and their metadata (document coupling, co-authorship, and co-occurrence) was exported. The metadata were analyzed and visualized with VOSViewer (Centre for Science and Technology Studies, Leiden University, The Netherlands). The articles were published between 1995 and 2020 and they had a median of 4.0 (interquartile range [IQR] = 5.0) citations. There were 5 clusters in the document coupling and 10 clusters in the co-authorship analysis. A total of 229 authors contributed to the articles and Kee B. Park contributed the most to articles (14 publications). Backward citation analysis was organized into 4 clusters and co-occurrence analysis into 7 clusters. The most common themes were pediatric neurosurgery, neurotrauma, and health system strengthening. The authors identified trends, contributors, and themes of highly cited global neurosurgery research. These findings can help establish collaborations and set the agenda in global neurosurgery research.

There is limited data regarding financial trends for procedural reimbursement in stroke care. A comprehensive understanding of such trends is important as continued progress is made to advance agreeable reimbursement models in the care of stroke patients. To evaluate monetary trends in Medicare reimbursement rates for commonly utilized procedures in stroke care from 2000 to 2019. The Centers for Medicare & Medicaid Services was queried for the included Current Procedural Terminology (CPT) codes and reimbursement data were extracted. The CPT codes compiled were the most commonly performed procedures for stroke-related International Classification of Diseases (ICD)-10 codes at our institution (I60-I63). Additionally, data were collected for alteplase and telestroke codes. The rate of change between procedures was compared utilizing an unpaired Student's t-test. All monetary data were adjusted for inflation to 2019 US dollars utilizing the US Consumer Price Index. After adjusting for inflation, the average reimbursement for stroke (ICD I60-I63) procedures decreased by 11.2% from 2000 to 2019 (average of −0.43% per year). The adjusted reimbursement rate for included telestroke codes decreased by 12.1% from 2010 to 2019 (average of −1.4% per year). From 2005 to 2019, the reimbursement for alteplase rose by 163.98% (average of +7.3% per year). When adjusted for inflation, Medicare reimbursement for common stroke procedures has decreased from 2000 to 2019. In contrast, reimbursement for alteplase has increased markedly. It is important to be aware of these trends in order to contextualize healthcare economic analyses and inform discussions.

Posterior inferior cerebellar artery (PICA) aneurysms are uncommon, and PICA pseudoaneurysms are even rarer. Endovascular treatment options exist for such lesions but usually require arterial sacrifice. This case report describes the successful treatment of a PICA pseudoaneurysm by trapping and end-to-end PICA reanastomosis. A 70-yr-old woman with a history of multiple microvascular decompressions for hemifacial spasm presented with new-onset facial droop caused by an enlarging, unruptured left PICA pseudoaneurysm. It was treated with trapping and end-to-end PICA reanastomosis, which is the first reported case of this technique for a PICA pseudoaneurysm. The bypass was patent, the pseudoaneurysm occluded, and the patient recovered well from her surgery. Pseudoaneurysm formation and growth after microvascular decompression is unusual. Albeit a deep and challenging bypass, trapping and an end-to-end PICA reanastomosis excluded the pseudoaneurysm, prevented further growth and/or rupture, and alleviated the patient's compressive symptoms.
