This study sought to scrutinize the clinical outcomes associated with first-pass mechanical thrombectomy strategies in the management of intracranial atherosclerosis (ICAS)-related large vessel occlusion (LVO). ⋯ Both aspiration thrombectomy and stent-retriever thrombectomy can be considered as primary therapeutic options for patients presenting with ICAS-LVO in the anterior circulation.

Idiopathic intracranial hypertension (IIH) is usually caused by sinus stenosis, which manifests in magnetic resonance venography (MRV) as occlusion or intraluminal webbing. We present the case of a 27-year-old patient with IIH, and time-of-flight (TOF) MRV only exhibited a rare "wrinkle sign," which was eventually proved to indicate sinus obstruction. The patient received venting and recovered. The TOF MRV provides a nonradioactive approach to identify IIH patients who potentially need intervention.

The influence of the placement of a lumbar interbody cage on subsidence risk: a biomechanical study.
Lumbar spinal fusion is a common surgical procedure that can be done with a variety of different instrumentation and techniques. Despite numerous research studies investigating subsidence risk factors, the impact of cage placement on subsidence is not fully elucidated. This study aims to determine whether placement of an expandable transforaminal lumbar interbody fusion cage at the center end plate or at the anterior apophyseal ring affects cage subsidence. ⋯ The subsidence stiffness increased with anterior apophyseal cage placement. Periphery end plate cortical bone architecture may play a role in resisting the impact of cage subsidence. To fully understand the effect of cage placement on cage subsidence, future studies should investigate its implications on native and diseased spine.

For surgical interventions, a precise understanding of the anatomical variations of the brain and defined anatomical landmarks to demarcate the regions of the temporal lobe is essential. Many anatomical studies have facilitated important surgical approaches to the temporobasal region. Because there is considerable sulcal variability, morphological analysis of the brain is imperative. The aim of this study was to define the boundaries of the temporal and occipital lobes and to define the variations in sulci and gyri in the inferior aspect. ⋯ Since the literature defines no clear separation between the temporal and occipital lobes, certain landmarks such as the preoccipital notch and a basal temporo-occipital line were suggested as ways of making the distinction. The parahippocampal ramus is a constant structure that can be used as a reliable landmark for the posterior end of the hippocampus.

The main treatment of low-grade glioma (LGG) is still surgical resection followed by radiotherapy and/or chemotherapy, which has certain limitations, including side effects and drug resistance. Immunotherapy is a promising treatment for LGG, but it is generally hindered by the tumor microenvironment with the limited expression of tumor antigens. ⋯ We obtained 3 reliable immune subtypes, and patients with the IS2 subtype are suitable for immunotherapy, in which NAMPT, SLC11A1, TNC, VIM, and SPP1 are predictive panel markers for ICB in the LGG group. Our findings provide a rationale for immunotherapy selection and prediction of patient prognosis in LGG patients.
