Hematoma expansion (H-Ex) in small-/medium-sized acute epidural hematoma (AEDH) cases upon emergency admission is critical. Predicting H-Ex can lead to early surgical interventions, improving outcomes, and eliminating the need to check for expansion via computed tomography (CT). This study aimed to identify the most reliable predictors of AEDH expansion. ⋯ LS can predict H-Ex in patients with pure AEDH for whom emergency surgery is unnecessary at admission. The time from injury and platelet counts must also be considered.

The Pfirrmann scoring system classifies lumbosacral disc degeneration based on magnetic resonance imaging signal intensity. The relationship between pre-existing disc degeneration and patient-reported outcome measures (PROMs) after one-level lumbar fusion is not well documented. The purpose of this study was to investigate the relationship between the severity of preoperative intervertebral disc degeneration and preoperative and postoperative PROMs in patients undergoing one-level lumbar fusion. ⋯ In patients undergoing one-level lumbar fusion, higher Pfirmann scores were associated with increased preoperative leg pain and greater 1-year postoperative improvement in back pain. Further studies into the relationship of preoperative disc degeneration and their impact on postoperative outcomes may help guide clinical decision-making and patient expectations.

This study aims to evaluate the length of stay (LOS) in patients who had adjunct middle meningeal artery embolization (MMAE) for chronic subdural hematoma after conventional surgery and determine the factors influencing the LOS in this population. ⋯ The interval between procedures and the number of medical and neurological complications were strongly associated with prolonged LOS in patients who had adjunct MMAE after open surgery. Reducing the interval between the procedures and potentially performing both under 1 anesthetic may decrease the burden on patients and shorten their hospitalizations.

Observational Study
Clinical, Radiological, and Surgical Features of Brain Metastases in Colorectal Cancer. A strong correlation between surgical patterns and outcome.
Brain metastases (BMs) from colorectal cancer (CRC) are a small percentage of metastatic patients and surgery is considered the best choice to improve survival. While most research has focused on the risk of CRC spreading to the brain, no studies have examined the characteristics of BMs in relation to surgery and outcome. In this study, we evaluate the clinical and radiologic features of BMs from CRC patients who underwent surgery and analyze their outcomes. ⋯ BMs derived from CRC have a significantly different prognosis depending on whether they present as a solid or cystic pattern. Although solid pattern is more common, cystic BMs in this tumor type are less frequent and are associated with a poorer prognosis, regardless of molecular expression, location, size, and adjuvant treatment.

The use of simulation has the potential to accelerate the learning curves and increase the efficiency of surgeons. However, there is currently a scarcity in models dedicated to skull base surgical approaches. Thus, the objective of this study was to develop a cost-effective mixed reality system consisting of an ultrarealistic physical model and augmented reality and evaluate its use in training surgeons on the retrosigmoid approach. ⋯ The ultrarealistic model efficiently allowed retromastoid access to the cerebellopontine angle. A tendency toward greater gains in performance in the group exposed to the model was verified. Scores from the self-satisfaction questionnaires demonstrated that participants considered the model relevant for neurosurgical training and increased confidence among surgeons.
