Imaging can help to diagnose CNS vasculitis. Yet so far, no imaging studies of CNS vasculitis at 7T are available. We share our experience of vessel wall imaging (VWI) at 7T in patients with suspected vasculitis.

Article Synopsis
  • The study investigated the clinical and radiological factors affecting the outcomes of acute ischemic stroke patients with isolated posterior cerebral artery (PCA) occlusion treated only with medical management.
  • A total of 585 patients were analyzed, revealing that 56% experienced poor functional outcomes, which were linked to older age, higher NIHSS scores, larger infarct volumes, and not receiving intravenous thrombolysis (IVT).
  • The research highlighted that factors like age, NIHSS score, infarct volume, and IVT status significantly influenced outcomes, while finding that complete recanalization after 24 hours improved recovery chances.

Background And Aims: Previous observational data indicate that young adults treated with intravenous thrombolysis (IVT) for acute ischemic stroke have more favorable outcomes and less complications when compared to older adults. Given the limited data on this topic, we aimed to provide more evidence on clinical outcomes and safety in such patients, using a large international thrombolysis registry.

Methods: In this prospective multicenter study, we used data from the Thrombolysis in Ischemic Stroke Patients (TRISP) registry from 1998 to 2020.

Background: The rising prevalence of acute ischemic stroke (AIS) in young adults, particularly with undetermined pathogenesis, is a growing concern. This study assessed risk factors, treatments, and outcomes between young AIS patients with undetermined and determined pathogeneses.

Methods And Results: This was a retrospective cohort study including AIS patients aged 18 to 55 years in Switzerland, treated between 2014 and 2022.

Background: Acute intracranial occlusion of the internal carotid artery (ICA) can be distinguished into (a) occlusion of the terminal ICA, involving the proximal segments of the middle or anterior cerebral artery (ICA-L/-T) and (b) non-terminal intracranial occlusions of the ICA with patent circle of Willis (ICA-I). While patients with ICA-L/-T occlusion were included in all randomized controlled trials on endovascular therapy (EVT) in anterior large vessel occlusion, data on EVT in ICA-I occlusion is scarce. We thus aimed to evaluate effectiveness and safety of EVT in ICA-I occlusions in comparison to ICA-L/-T occlusions.
