Intracranial dural arteriovenous fistulas with deep venous drainage: a single-center retrospective cohort study.

Objective: Dural arteriovenous fistulas (DAVFs) with deep venous drainage (DVD) (DAVFs-DVD) are characteristically associated with non-hemorrhagic neurological deficits, most notably cognitive impairment. Large studies have yet to thoroughly characterize these DAVFs. We conducted an analysis of the largest cohort of DAVFs-DVD to provide a comprehensive characterization of this specific subset.

A systematic review and meta-analysis of endovascular treatment of carotid blowout syndrome.

Unlabelled: Carotid Blowout Syndrome (CBS) is a rare and life-threatening condition that necessitates prompt intervention to prevent fatal hemorrhage. This study compares the outcomes of two primary endovascular approaches: reconstructive interventions, which aim to preserve carotid artery function using stents or balloon angioplasty, and deconstructive interventions, which involve vessel occlusion to halt bleeding. A systematic review and meta-analysis were performed by searching multiple databases for relevant studies published from January 2000 to August 2023.

Trends and hotspots of stereoelectroencephalogram from 2002 to 2023: a bibliometric analysis.

Background: Stereoelectroencephalography (SEEG), as a minimally invasive method that can stably collect intracranial electroencephalographic information over long periods, has increasingly been applied in the diagnosis and treatment of intractable epilepsy in recent years. Over the past 20 years, with the advancement of materials science and computer science, the application scenarios of SEEG have greatly expanded. Bibliometrics, as a method of scientifically analyzing published literature, can summarize the evolutionary process in the SEEG field and offer insights into its future development prospects.

Glial scarring limits recovery following decompressive surgery in rats with syringomyelia.

Syringomyelia is a neurological disease that is difficult to cure, and treatments often have limited effectiveness. In this study, a rat model of syringomyelia induced by epidural compression was used to investigate the factors that limit the prognosis of syringomyelia. After we treated syringomyelia rats with surgical decompression alone, MRI revealed that the syringomyelia rats did not show the expected therapeutic effect.

Drug-eluting stents versus bare-metal stents for intracranial atherosclerotic stenosis: a systematic review and meta-analysis.

This systematic review aimed to evaluate the efficacy and safety of DES compared with bare-metal stents (BMS) for intracranial atherosclerotic stenosis (ICAS).

Clinical features and outcomes of basilar invagination.

Basilar invagination has been classified into two types by Goel: Type A is defined mechanical instability of the atlantoaxial joint with upward displacement of the odontoid process while Type B is characterized by stable atlantoaxial joints. This study reviews the association between radiological features and symptomatology and prognosis of two types of basilar invagination for better clinical management. A retrospective analysis was conducted including 141 patients diagnosed with basilar invagination who underwent surgical treatment from January 2016 to December 2020.

PTP1B Modulates Carotid Plaque Vulnerability in Atherosclerosis Through Rab5-PDGFRβ-Mediated Endocytosis Disruption and Apoptosis.

Background: Protein tyrosine phosphatase 1B (PTP1B) is a protein tyrosine phosphatase and modulates platelet-derived growth factor (PDGF)/platelet-derived growth factor receptor (PDGFR) signaling in vascular smooth muscle cells (VSMCs) via endocytosis. However, the related molecular pathways that participated in the interaction of endo-lysosome and the trafficking of PDGFR are largely unknown. This study aims to determine the subcellular regulating mechanism of PTP1B to the endo-lysosome degradation of PDGFR in atherosclerotic carotid plaques, thereby offering a potential therapeutic target for the stabilization of carotid plaques.
