The clinical relevance of low-grade intraventricular hemorrhage (IVH) in very preterm infants remains debated. We investigated how cMRI and cranial ultrasound (cUS) influence IVH detection and grading and how differences between the Papile and Volpe classifications affect interpretation and outcome stratification. This retrospective, single-center cohort study included 507 consecutively born infants at < 32 weeks’ gestation with serial cUS and cMRI at term-equivalent age (2009-2018). IVH was graded according to the Papile and Volpe classifications. Clinical parameters and neurodevelopmental outcomes at 24 months of corrected age were assessed (Bayley Scales of Infant Development). Univariable and multivariable regression analyses were performed. Among 507 preterm infants, IVH was identified in 85 (16.8
Chronic subdural hematoma (cSDH) has traditionally been treated surgically, with a 20
Acute basilar artery occlusion (BAO) carries high rates of death and disability despite endovascular therapy, and the optimal technique remains unclear. We compared contact aspiration (CA) alone with combined CA plus stent retriever (CA + SR) and identified factors associated with first-pass reperfusion and 3‑month outcome. In the prospective multicenter SARA-3 registry, the primary outcomes compared between CA and CA + SR were first-pass recanalization (modified Treatment in Cerebral Infarction [mTICI] 2b–3) and 3‑month functional independence. Secondary outcomes were final recanalization, procedural time, safety, 24‑h NIHSS, and mortality. Factors associated with unfavorable outcome (modified Rankin Scale [mRS] 3–6) were assessed by Firth penalized logistic regression, with first-line technique forced in as a sensitivity analysis. Among 68 patients (median admission National Institutes of Health Stroke Scale [NIHSS] 11), 50 (73.5
Middle meningeal artery embolization (MMAE) is increasingly used for chronic subdural hematoma (CSDH), but the relationship between injected liquid-embolic volume and outcomes is unclear. We evaluated dose–outcome associations and searched for a minimum effective dose. This retrospective multicenter cohort included 313 patients treated with liquid embolic agents at 12 MESH Registry centers from 2016 to 2024. MMAE was performed alone in 172 patients (55.0
