Comparative Study
Effect of surgeon experience on surgical outcome of 80-year-old or older intracranial meningioma patients.
Previous reports suggest that more experienced surgeons have better postoperative outcomes in neurosurgery. We studied whether this association is found in a fragile cohort of ≥80-year-old intracranial meningioma (IM) patients. ⋯ In a high-volume academic hospital, less experienced neurosurgeons seem to achieve similar results as the more experienced neurosurgeons, even when operating on selected highly fragile meningioma patients.

No large dataset-derived standard has been established for normal or pathologic human cerebral ventricular and cranial vault volumes. Automated volumetric measurements could be used to assist in diagnosis and follow-up of hydrocephalus or craniofacial syndromes. In this work, we use deep learning algorithms to measure ventricular and cranial vault volumes in a large dataset of head computed tomography (CT) scans. ⋯ This is the first study to measure lateral ventricular and cranial vault volumes in a large dataset, made possible with artificial intelligence. We provide a robust method to establish normal values for these volumes and a tool to report these on CT scans when evaluating for hydrocephalus.

The occurrence of coronavirus disease 2019 (COVID-19) has overwhelmed the blood supply chain worldwide and severely influenced clinical procedures with potential massive blood loss, such as clipping surgery for aneurysmal subarachnoid hemorrhage (aSAH). Whether acute normovolemic hemodilution (ANH) is safe and effective in aneurysm clipping remains largely unknown. ⋯ ANH significantly increased postoperative hemoglobin levels, and it may hold the potential to improve patients' outcomes. Routine use of ANH should be considered in aneurysm clipping surgery.

The purpose of this study was to compare clinical results of microendoscopic laminectomy (MEL) with those of unilateral biportal endoscopic laminectomy (UBEL) in patients with single-level lumbar spinal canal stenosis. ⋯ The UBEL method is a more useful technique than the MEL method as it requires a smaller bone resection area and produces fewer complications.

A paucity of literature is available discussing the associated risk factors, treatment options (including the use of minimally invasive surgery), and outcomes related to lumbar disc herniation (LDH) in children. We have discussed the risk factors for disc disease among pediatric patients and evaluated the efficacy of the minimally invasive approach. ⋯ Risk factors similar to those for adult LDH, such as an elevated body mass index, can be seen in the pediatric population. However, some unique risk factors such as post-traumatic LDH were found in the pediatric age group. Minimally invasive techniques are demonstrably safe and useful in this patient population.
