Comparative StudyTransradial versus transfemoral access routes for diagnostic cerebral angiography: a large single-center comparative cost-analysis study.
Recently, the transradial (TR) approach has become a common alternative because of its safety profile and increased patient satisfaction compared with the transfemoral (TF) route. Both routes are associated with their respective associated costs, and differences typically emerge on the basis of patient anatomy, operator expertise, and occurrence of complications. The authors' objective was to compare the overall costs of diagnostic cerebral angiography via both routes and to shed light on the individual equipment costs of each route. ⋯ Overall, the authors' study showed that the TR approach can be a less expensive option for patients undergoing diagnostic cerebral angiography, especially if complications occur. Future studies may corroborate these findings and potentially lead to the adoption of TR as a low-cost, efficient, gold-standard technique for cerebral angiography.

A taxonomy for deep cerebral cavernous malformations: subtypes of basal ganglia lesions.
Anatomical taxonomy is a practical tool that has successfully guided clinical decision-making for patients with brain arteriovenous malformations and brainstem cavernous malformations (CMs). Deep CMs are similarly complex lesions that are difficult to access and highly variable in size, shape, and position. The authors propose a novel taxonomy for deep CMs in the basal ganglia based on clinical presentation (syndromes) and anatomical location. ⋯ The study confirms the authors' hypothesis that this taxonomy for basal ganglia CMs meaningfully guides the selection of surgical approach and resection strategy. Furthermore, the proposed taxonomy can increase the diagnostic acumen at the patient bedside, help identify optimal surgical approaches, enhance the consistency of clinical communications and publications, and improve patient outcomes.

Comparative StudyMicroelectrode recording and hemorrhage in functional neurosurgery: a comparative analysis in a consecutive series of 645 procedures.
Functional stereotactic neurosurgery including deep brain stimulation (DBS) and radiofrequency lesioning is well established and widely used for treatment of movement disorders and various other neurological and psychiatric diseases. Although functional stereotactic neurosurgery procedures are considered relatively safe, intracranial hemorrhage resulting in permanent neurological deficits may occur in 1%-3% of patients. Microelectrode recording (MER) has been recognized as a valuable tool for refining the final target in functional stereotactic neurosurgery. Moreover, MER provides insight into the underlying neurophysiological pathomechanisms of movement disorders and other diseases. Nevertheless, there is an ongoing controversy on whether MER increases the risk for hemorrhage. The authors aimed to compare the risk of hemorrhage in functional stereotactic neurosurgical procedures with regard to the use of MER. ⋯ Intraoperative MER did not increase the overall risk of hemorrhage in the authors' experience using primarily a single MER trajectory and a guiding cannula.

Long-term clinical outcomes of hypofractionated stereotactic radiotherapy using the CyberKnife robotic radiosurgery system for jugular foramen schwannomas.
Jugular foramen schwannomas (JFSs) are rarely seen, benign tumors with slow growth. Today, management options for JFSs include observation, surgery, and radiation. However, the optimal treatment strategy remains controversial. Stereotactic radiosurgery serves as a minimally invasive alternative or adjuvant therapeutic regimen of microsurgery. Gamma Knife radiosurgery is suitable for patients with JFS who have small- and medium-sized tumors and normal cranial nerve (CN) function. Hypofractionated stereotactic radiotherapy (HSRT) offers a potential radiobiological advantage and may result in better preservation of normal structures compared to single-fraction stereotactic radiosurgery. The aim of the article was to review the clinical and radiographic outcomes of patients with JFS who were treated using HSRT. ⋯ HSRT proved to be a safe and effective primary or adjuvant treatment strategy for JFSs, although 14 patients (18.9%) experienced some degree of delayed symptomatic deterioration posttreatment. This therapeutic option was demonstrated to provide both excellent tumor control and improvement in CN function.

Publication patterns of posters and oral presentations at the Annual Meeting of the Joint AANS/CNS Cerebrovascular Section.
The American Association of Neurological Surgeons (AANS) and Congress of Neurological Surgeons (CNS) Joint Cerebrovascular (CV) Section serves as a centralized entity for the dissemination of information related to CV neurosurgery. The quality of scientific conferences, such as the CV Section's Society of NeuroInterventional Surgery Annual Meeting, can be gauged by the number of poster and oral presentations that are published in peer-reviewed journals. However, publication rates from the CV Section's meetings are unknown. The objective of this study was to assess the rate at which abstracts presented at the AANS/CNS CV Section Annual Meeting from 2014 to 2018 were subsequently published in peer-reviewed journals. ⋯ Nearly half of all poster and oral presentations at the annual meetings of the AANS/CNS Joint CV Section from 2014 to 2018 have been published in PubMed-indexed, peer-reviewed journals. The average number of citations per publication (10.89 ± 16.37) reflects the high quality of abstracts accepted for presentation. It is important to continuously assess the quality of research presented at national conferences to ensure that standards are being maintained for the advancement of clinical practice in a given area of medicine. Conference abstract publication rates in peer-reviewed journals represent a way in which research quality can be gauged, and the authors encourage others to conduct similar investigations in their subspecialty area of interest and/or practice.
