The aim of the present study was to retrospectively analyze and investigate the clinical data of 704 cases of ruptured intracranial aneurysms (RIAs) and unruptured intracranial aneurysms (UIAs). The risk factors predicting aneurysm rupture were explored from the perspective of the clinical characteristics of intracranial aneurysm (IA). ⋯ The present findings indicated that hyperlipidemia and atherosclerosis have a protective effect on aneurysm rupture, and different anatomical sites of IA may be risk factors for the occurrence of IA rupture. Among the anatomical sites of IA, the anterior communicating artery and posterior communicating artery have a higher fracture risk.

Brain tumors display significant inter and intratumoral heterogeneity, impacting disease progression and outcomes. Preserving surgically resected tissue is vital for ensuring accurate research results to enhance understanding of tumor pathophysiology. This study evaluates tissue integrity and viability of tissue resected using 2 surgical devices for tumor resection: a mechanical microdebrider (MD) and an ultrasonic aspirator (UA). ⋯ Surgical handheld devices provide valuable, high-quality tissue samples for research. Surgeon preference, tumor pathology, and anatomical location dictate device choice. Both MD and UA devices are reliable for obtaining quality tissue specimens, facilitating translational neuro-oncology research.

The external ventricular drain (EVD) is an important instrument in managing patients in neurointensive care (NICU). A frequent and sometimes severe complication is ventriculostomy-related infection (VRI). This study aimed to evaluate the effects of biweekly VRI screening by CSF sampling on the clinical course and rate of VRI. ⋯ Screening was associated with a higher number of culture-confirmed VRI cases. In addition, screening did not detect VRI at an earlier stage and was not associated with a reduction in the rate of permanent hydrocephalus. No clinical benefit of screening was found. Frequent CSF sampling might contribute to infection. Based on these findings, CSF screening for VRI cannot be recommended.

To assist doctors in making better treatment decisions and improve patient prognosis, it is important to determine which therapy modalities are suitable for various forms of idiopathic hypertrophic cranial pachymeningitis (IHCP). ⋯ The extent and shape of the lesion and susceptibility to corticosteroids are potential factors that could influence recurrence. Futhermore, this paper also proposes the fibroblasts as a new therapeutic target which may improve the quality of prognostic survival of patients.

This study sought to quantify radiographic differences in psoas morphology, great vessel anatomy, and lumbar lordosis between supine and prone intraoperative positioning to optimize surgical planning and minimize the risk of neurovascular injury. ⋯ Relative to the vertebral body, the psoas demonstrated substantial lateral mobility when prone, and posterior retraction specifically at L5. IVC and right iliac vein experienced significant anterior mobility-particularly at more cephalad levels. Prone position enhanced segmental lordosis and may be critical to optimizing sagittal restoration.
