Background And Objectives: The benefit of mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS) with basilar artery occlusion (BAO) and a baseline National Institute of Health Stroke Scale (NIHSS) score <10 is unclear because this subpopulation has been substantially excluded from large clinical trials. The aim of our study was to determine whether MT ± IV thrombolysis (IVT) improves functional outcomes compared with IVT alone in patients with BAO and a NIHSS score <10.

Methods: We emulated a hypothetical trial including adult patients with BAO, a baseline NIHSS score <10, and prestroke modified Rankin scale (mRS) scores 0-2, comparing MT (±IVT) with IVT alone.

Introduction: Stroke in young people shares traditional modifiable risk factors with older groups, and greatly affects quality of life. However, evidence on the effectiveness of educational interventions in young populations, aiming at spreading stroke knowledge and enhancing prevention, is still scarce. We evaluated baseline knowledge of stroke and possible improvements after an educational intervention among Italian high school students, also considering differences related to sex and type of school.

Efficacy and safety of mechanical thrombectomy (MT) for stroke with posterior circulation large vessel occlusion (LVO) is still under debate. We aimed to compare the outcomes of stroke patients with posterior circulation LVO treated with intravenous thrombolysis (IVT) (< 4.5 h after symptom onset) plus MT < 6 h after symptom onset with those treated with IVT alone (< 4.

Article Synopsis
  • The study investigates predictors of hemorrhagic transformation (HT) and cerebral edema (CED) in stroke patients undergoing endovascular treatment after experiencing large vessel occlusion (LVO).
  • It analyzes data from 1,400 patients to find clinical and procedural factors associated with these complications, identifying variables like diabetes, NIHSS scores, and ASPECTS ratings as significant predictors.
  • Results show that HT occurred in 18% of patients and CED in 19.2%, with general anesthesia linked to a lower risk of HT, while factors like longer onset-to-groin times and invasive procedures raised the risk for both complications.

Background: Carotid artery disease is highly prevalent and a main cause of ischemic stroke and vascular dementia. There is a paucity of information on predictors of serious vascular events. Besides percentage diameter stenosis, international guidelines also recommend the evaluation of qualitative characteristics of carotid artery disease as a guide to treatment, but with no agreement on which qualitative features to assess.

Monogenic cerebral small vessel diseases are a topic of growing interest, as several genes responsible have been recently described, and new sequencing techniques such as Next-generation sequencing are available. Brain imaging is significant for the detection of these diseases. Since it is often performed at an initial stage, an MRI is a key to selecting patients for genetic testing and for interpreting nextgeneration sequencing reports.

Objectives: The Montreal Cognitive Assessment (MoCA) is a cognitive screening test largely employed in vascular cognitive impairment, but there are no data about MoCA longitudinal changes in patients with cerebral small vessel disease (SVD). We aimed to describe changes in MoCA performance in patients with mild cognitive impairment (MCI) and SVD during a 2-year follow-up, and to evaluate their association with transition to major neurocognitive disorder (NCD).

Materials And Methods: Within the prospective observational VMCI-Tuscany Study, patients with MCI and SVD underwent a comprehensive clinical, neuropsychological, and functional evaluation at baseline, and after 1 and 2 years.

Background: Intravenous thrombolysis (IVT)-ineligible patients undergoing direct thrombectomy tended to have poorer functional outcome as compared with IVT-eligible patients undergoing bridging therapy. We aimed to assess radiological and functional outcomes in large vessel occlusion-related stroke patients receiving direct thrombectomy in the presence of absolute exclusion criteria for IVT vs relative exclusion criteria for IVT and vs non-exclusion criteria for IVT.

Methods: A cohort study on prospectively collected data from 2282 patients enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke cohort for treatment with direct thrombectomy (n = 486, absolute exclusion criteria for IVT alone; n = 384, absolute in combination with relative exclusion criteria for IVT; n = 777, relative exclusion criteria for IVT alone; n = 635, non-exclusion criteria for IVT).

Introduction: Although pathogenesis of small vessel disease is poorly understood, increasing evidence suggests that endothelial dysfunction may have a relevant role in development and progression of small vessel disease. In this cross-sectional study, we investigated the associations between imaging signs of small vessel disease and blood biomarkers of endothelial dysfunction at two different time points in a population of ischaemic stroke patients.

Patients And Methods: In stroke patients treated with intravenous thrombolysis, we analysed blood levels of von Willebrand factor, intercellular adhesion molecule-1, vascular cell adhesion molecule-1 and vascular endothelial growth factor.

Article Synopsis
  • The study examined the link between types of atrial fibrillation (paroxysmal vs. sustained) and the occurrence of early ischaemic recurrences after an acute stroke in patients.
  • Out of 2150 patients, those with sustained atrial fibrillation experienced a higher percentage of early ischaemic recurrences (6.2%) compared to those with paroxysmal atrial fibrillation (3.3%).
  • However, after considering other health risks, sustained atrial fibrillation did not show a significantly increased risk for early recurrence, suggesting that other factors may be more influential.
