Assess the complications, clinical outcomes, and angiographic results of endovascular treatment (EVT) for ruptured intracranial posterior circulation aneurysms in small arteries, and identify their risk factors. ⋯ Reconstructive EVT for ruptured intracranial posterior circulation small artery aneurysms was generally safe and effective. However, the risk of complications and unfavorable clinical outcomes persisted. External ventricular drainage was a significant risk factor for in-hospital complications, whereas older age and higher World Federation of Neurosurgical Societies grades were predictors of unfavorable clinical outcomes.

Machine Learning Algorithms for Neurosurgical Preoperative Planning: A Comprehensive Scoping Review.
Preoperative neurosurgical planning is an important step in avoiding surgical complications, reducing morbidity, and improving patient safety. The incursion of machine learning (ML) in this domain has recently gained attention, given the notable advantages in processing large datasets and potentially generating efficient and accurate algorithms in patient care. We explored the evolving applications of ML algorithms in the preoperative planning of brain and spine surgery. ⋯ ML algorithms for preoperative neurosurgical planning are being developed for efficient, automated, and safe treatment decision-making. However, future studies are necessary to validate their objective performance across diverse clinical scenarios. Enhancing the robustness, transparency, and understanding of ML applications will be crucial for their successful integration into neurosurgical practice.

This study endeavored to investigate the influencing factors of pedicle screw torque measured during surgery and the correlation between manual palpation scores and screw torque. ⋯ The BMD of the lumbar is an independent factor that influences the measured torque applied to pedicle screws during surgery. A significant and robust positive correlation exists between the intraoperative screw placement tactile sensation and the torque experienced. It is advisable to reinforce the screw channel with bone cement when the tactile score is ≤2.5 and the torque is ≤ 1.3 Nm.

The purpose of this study was to investigate whether the preservation of the anterior edge of the vertebral body affects the cage subsidence and clinical outcomes after anterior cervical discectomy and fusion (ACDF) using zero-profile cages. ⋯ For patients who undergo ACDF with zero-profile cages, especially those with a higher surgical segment, bone protection at the anterior edge of the vertebral body can effectively reduce the risk of zero-profile cage subsidence, but there is no difference in the final clinical effect.
