Introduction: Flow diversion is an effective first-line treatment for intracranial aneurysms; however, the rate of incomplete occlusion is not insignificant. Data in neuroendovascular literature is limited regarding the implications of persistent incomplete occlusion despite flow diversion.

Methods: We conducted a retrospective analysis of a prospectively maintained database and identified 125 consecutive patients with treatment naïve intracranial aneurysms who underwent flow diversion with the PED from April 2014 - November 2022.

Background: Intracranial aneurysms are the main cause of subarachnoid hemorrhage (SAH), a severe stroke with devastating effects. However, there are no existing medications for intracranial aneurysms (IAs) and novel therapeutic targets are required.

Methods: We performed a summary data-based Mendelian Randomization (MR) analysis to explore the causal association between circulating plasma proteins and the risk of IAs and SAH.

Department of Neurosurgery & Stroke, Institute of Clinical Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan.

Objective: Middle cerebral artery (MCA) aneurysms are difficult to treat with coil embolization (CE) due to their location and shape, but the number of CE-treated MCA has gradually increased as treatment techniques have improved. However, the outcomes of CE for ruptured MCA aneurysms are poorly understood. This study aimed to evaluate the outcomes of CE for ruptured MCA aneurysms.

Modifiable lifestyle factors and risk of intracranial aneurysm: A univariate and multivariate Mendelian randomisation study.

Neuroscience

February 2025

Department of Neurosurgery, the First Affiliated Hospital, Jiangxi Medical College, Nanchang University, No. 17 Yongwaizheng Street, Nanchang, 330006, Jiangxi, China. Electronic address:

The aim of this study was to assess the potential causal relationship between lifestyle factors and intracranial aneurysms (IAs) using a two-sample Mendelian randomization (MR) approach. The study used a pooled dataset from a genome-wide association study that covered information on 24 lifestyle factors, intracranial aneurysm cases, subarachnoid hemorrhage, and unruptured aneurysms. Five MR methods were applied for analysis by selecting single nucleotide polymorphisms as instrumental variables, with the inverse variance weighting method as the main method.

Article Synopsis
  • Statin therapy during coil embolization for intracranial aneurysms (IAs) may lower the rates of aneurysm recurrence and the need for retreatment.
  • A post hoc analysis of data from the Hydrogel Endovascular Aneurysm Treatment Trial showed that patients on statins had a recurrence rate of 3.8%, compared to 10.7% in those not on statins.
  • Statin use was particularly effective in patients with unruptured aneurysms, significantly reducing recurrence compared to nonstatin users, while having no measurable benefit for ruptured aneurysms.

Background: Ruptured intracranial aneurysms lead to significant mortality and morbidity. Recent advancements have suggested staged coiling with subsequent flow diverter stent placement may reduce the risk of hemorrhage with dual antiplatelet therapy (DAPT) or stent thrombosis in the acute inflammatory phase after aneurysm rupture while still appropriately mitigating risk of aneurysmal rehemorrhage.

Materials And Methods: A systematic review and single-arm meta-analysis was conducted.

Objective: The objective of this study is to devise an indicator system to assess the quality of nursing care in the context of interventional therapy for intracranial aneurysms (IA) in China. This will furnish a standardized and quantitative framework for the monitoring and assessment of nursing quality within the IA interventional therapeutic field.

Methods: The indicators and their associated weights within the evaluation system for nursing quality in interventional therapy for IA were determined based on the theoretical framework of the three-dimensional quality model, specifically the "structure-process-outcome" paradigm.

Carotid-cavernous aneurysms (CCAs) have the potential for growth, and their risk of rupture can lead to severe complications. Treatment is typically recommended to prevent these complications, with endovascular therapy being the preferred approach due to the challenging surgical access. This case presents a rare instance of rupture of a CCA that had been previously treated with a flow-diverting stent, which resulted in the development of a carotid-cavernous fistula, requiring venous access endovascular treatment.

Background And Purpose: Flow diversion (FD) has expanded beyond initial indications (proximal carotid artery aneurysms) to include distal circulation aneurysms (on the anterior, middle, or posterior cerebral arteries). Our objective was to examine results obtained from aneurysms in these locations in the Flow Diversion in the Treatment of Intracranial Aneurysms Trial (FIAT) which compared FD with alternative standard management options (ASMO).

Materials And Methods: FIAT was an all-inclusive parallel-group 1:1 randomized study comparing FD with one of 4 ASMOs (coiling +/-stenting, parent vessel occlusion (PVO), clipping, or observation, pre-specified by clinical judgment).

Recent advancements in endovascular treatment (EVT) and different views on optimal management for posterior communicating artery (PComA) aneurysms with oculomotor nerve palsy (ONP) highlight a need to compare recovery timelines between microsurgery and EVT; heterogeneous outcomes and influencing factors may also affect results. A comprehensive systematic review and meta-analysis were conducted by searching PubMed, Embase, Scopus, and Web of Science databases. The extracted data encompassed patient demographics, details on treatment modalities and timing, and characteristics of PComA aneurysms ONP caused by either unruptured or ruptured aneurysms.
