Rescue stenting after failed mechanical thrombectomy: The RES-CAT study.

Introduction: The efficacy of intracranial rescue stenting (RS) following failed mechanical thrombectomy (MT) in large-vessel occlusion (LVO) stroke remains uncertain. We aimed to evaluate clinical outcomes of RS in patients with anterior circulation LVO stroke following unsuccessful MT.

Patients And Methods: We conducted a retrospective analysis using the Stroke Code Registry of Catalonia (January 2016-March 2022), a prospective, population-based registry including patients treated at 10 comprehensive stroke centers.

Randomized Study Comparing First-Line Dual Versus Single-Stent Retriever Technique: TWIN2WIN.

Background: The double-stent retriever (SR) technique has been described as an effective rescue technique when single-SR fails to induce recanalization. We aimed to assess the safety and efficacy of first-line double-SR in patients with stroke undergoing thrombectomy.

Methods: This was a multicenter, randomized, controlled, blinded adjudicated primary outcome study.

Long and Large Stentrievers Improve Reperfusion Outcomes in Acute Intracranial Terminal Internal Carotid Artery Occlusion: Interim Results of the Rossetti Registry.

Introduction: Although stentrievers (SRs) are widely used for mechanical thrombectomy (MT), the impact of device dimensions on optimizing reperfusion outcomes in high clot burden cases is unclear. Our study aimed to investigate the effect of SR size on angiographic and clinical outcomes in patients with acute terminal internal cerebral artery (TICA) occlusion.

Methods: We analyzed ROSSETTI registry data to compare technical and clinical outcomes of TICA occlusion patients treated with MT without rescue therapy, according to SR diameter and length: 6 × 41-50 mm, 6 × 20-40 mm, and <6 × 20-50 mm.

Iatrogenic cerebral amyloid angiopathy: Two case reports to explore clinical heterogeneity and pathological patterns.

Introduction: These case reports illustrate Iatrogenic Cerebral Amyloid Angiopathy (iCAA) due to neurosurgical procedures. Recent studies propose prion transmission during neurosurgery as a potential mechanism for β-amyloid seed implantation, linking neurosurgical history to the development of iCAA. The majority of reported cases in the literature have an unfavorable prognosis, with recurrence of intracerebral hemorrahge (ICH) and subsequent death during the first months of follow-up.

Hematoma expansion prediction in intracerebral hemorrhage patients by using synthesized CT images in an end-to-end deep learning framework.

Spontaneous intracerebral hemorrhage (ICH) is a type of stroke less prevalent than ischemic stroke but associated with high mortality rates. Hematoma expansion (HE) is an increase in the bleeding that affects 30%-38% of hemorrhagic stroke patients. It is observed within 24 h of onset and associated with patient worsening.
