Some have suggested that trabeculae within the transverse sinuses (chordae Willisii) might restrict flow and potentially contribute to thrombus organization. In addition, these structures might be encountered with endovascular procedures within the transverse sinus and are now readily seen on imaging. Therefore as anatomic studies of these structures are scant, the current study aimed to better elucidate these structures within the transverse sinus via a morphologic study in cadavers. ⋯ To date, a comprehensive anatomic evaluation of the intraluminal chordae of the transverse sinuses has been lacking. Knowledge of these bands is also essential to those performing endovascular procedures of the dural venous sinuses and for those interpreting imaging of these structures.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has consistently changed medical practice throughout specialties, regardless of their contribution in facing the disease itself. We surveyed neurosurgeons worldwide to investigate the situation they are experiencing. ⋯ Most neurosurgeons worldwide reported work reorganization and practices that respond to current international guidelines. Differences in practice might be related to the perception of the pandemic and significant differences in the health systems. Sharing data and experiences will be of paramount importance to address the present moment and challenges in the near future.

We sought to review the types of incidental durotomies (IDs) that occurred during the endoscopic stenosis lumbar decompression through interlaminar approach (ESLD) and discuss the management strategies according to our classification. ⋯ ID is a more common surgical complication in ESLD compared with the transforaminal approach. The endoscopic patch blocking dura repair technique should be considered in type 1 to type 3A of dura tear with good prognosis and clinical outcome. Consideration is made for conversion to open repair in types 3B, 3C and 4 dura tears with fair to poor outcome.

Although spinal decompression surgery is an effective treatment for myelopathy-induced upper limb pain, some postoperative patients suffer from residual pain in spite of adequate decompression. However, the neural mechanism underlying the poor outcome of pain relief is still unclear. The goal of this study was to explore the brain mechanisms involved in the poor recovery of upper limb pain after the spinal decompression surgery by using functional connectivity (FC) analysis. ⋯ Our study showed that FC between the postCG and DLPFC may be a predictor of pain relief. This result suggested that assessing FC can lead to more informed surgical interventions for cervical spondylotic myelopathy.

The factors that attract and concern medical students about a career in neurosurgery have never been clearly characterized or delineated in a large nationwide cohort of medical students intending to pursue a career in neurosurgery. The objective of the present study was to characterize the factors that influence medical student interest in neurosurgery and assess the effects of a formal neurosurgery training course on participants' perceptions of a career in neurosurgery. ⋯ A training camp for students pursuing a neurosurgery subinternship was effective in providing transparency and positively influencing the factors that attract and concern students about a career in neurosurgery. Characterization of medical student perceptions of neurosurgery from a large, nationwide cohort of students pursuing a subinternship has provided novel data and could help identify factors protecting against burnout later in life.
