To construct a universally applicable nomogram using computed tomography perfusion (CTP) parameters based on Rapid processing of PerfusIon and Diffusion (RAPID) software for evaluating the prognosis of acute anterior circulation large vessel occlusion (LVO) treated by endovascular therapy. ⋯ Our nomogram can be used as a simple and reasonable tool to predict the prognosis of acute anterior circulation LVO treated by endovascular therapy. The CTP parameter VCBF<30% obtained by RAPID software was an important predictive factor in this model.

The parapharyngeal space (PPS) and infratemporal fossa (ITF) present significant challenges for endoscopic skull base surgery due to their complex anatomy and lack of clear bony landmarks. This study aims to propose a systematic compartmentalization of the PPS and ITF, based on key anatomical structures, to optimize surgical planning and approaches. ⋯ A three-space model of the PPS and ITF, defined by specific muscle planes, provides a structured framework to guide endoscopic skull base approaches. This model allows for targeted selection of surgical routes based on lesion location and its relationship with the internal carotid artery, aiming to minimize procedural risks.

This study aimed to determine the predictive factors for analgesic reduction and amelioration of mobility following percutaneous sacroplasty in patients with insufficiency fractures or metastatic lesions. ⋯ Percutaneous sacroplasty was effective for pain relief, functional outcomes, and short-term satisfaction. The absence of concomitant vertebroplasty was significantly associated with VAS improvements.

In recent years, several studies have shown the presence of a linear correlation between the PI and spondylolisthesis . However, no study has attempted to investigate a potential association between facet sagittal angle and spinopelvic parameters, especially PI in the normal population. ⋯ The PI seems to be correlated to the other spondylolisthesis risk factors: facet tropism and female gender. It carries the heaviest load in the progression towards sagittally oriented facet joints, which might lead to segmental instability and eventual spinal pathologies.

To determine the incidence of subdural hygroma(SDH) on routine early post-operative imaging following foramen magnum decompression(FMD) with dural opening in patients with Chiari 1 malformation (CM1). ⋯ SDH is a common finding in the early post-operative scans of patients undergoing FMD and dural opening for CM1. While nearly two-thirds of these patients are asymptomatic, SDH with ventriculomegaly can be associated with mortality and significant morbidity and may require emergency treatment.
