Brain arteriovenous malformations (bAVMs) are high-flow vascular anomalies associated with a significant risk of intracranial haemorrhage, particularly in young individuals. Standard treatments-including microsurgery, stereotactic radiosurgery (SRS), and endovascular embolization-are not feasible for all patients, especially those with high-grade or surgically inaccessible lesions. Bevacizumab, a monoclonal antibody targeting vascular endothelial growth factor (VEGF), has emerged as a potential medical therapy aimed at modulating angiogenesis and managing post-treatment complications.

Transcranial Magnetic Stimulation-Electroencephalography (TMS-EEG) is a non-operative technique that allows for magnetic cortical stimulation (TMS) and analysis of the electrical currents generated in the brain (EEG). Despite the regular utilization of both techniques independently, little is known about the potential impact of their combination in neurosurgical practice. This scoping review, conducted following PRISMA guidelines, focused on TMS-EEG in epilepsy, neuro-oncology, and general neurosurgery.

Introduction: The integration of novel electronic informed consent platforms in healthcare has undergone significant growth over the last decade. Adoption of uniform, accessible, and robust electronic online consenting applications is likely to enhance the informed consent process and improve the patient experience and has the potential to reduce medico-legal ramifications of inadequate consent. A systematic review and meta-analysis was conducted to evaluate the utility of novel electronic means of informed consent in surgical patients and discuss its application to neurosurgical cohorts.

Introduction: Germinal matrix / intraventricular haemorrhage (GMIVH) remains a significant complication of prematurity. The more severe grades are associated with parenchymal haemorrhagic infarction (PHI) and hydrocephalus. A temporising procedure is usually the first line in management of neonatal post-haemorrhagic hydrocephalus (nPHH) as the risk of failure of a permanent cerebrospinal fluid (CSF) diversion is higher in the early stage.
