N2 - Objective: Few data regarding causes and outcomes of haemorrhagic stroke (HS) in term neonates are available. We characterised risk factors, mechanism and short-term outcomes in term and late preterm neonates with acute HS. Design: Prospective cohort. Setting: Single-centre tertiary care stroke registry. Subjects: Term and late preterm neonates (≥34 weeks gestation), born 2004-2010, with acute HS ≤28 days of life were identified, and clinical information was abstracted. Short-term outcomes were assessed via standardised neurological exam and rated using the Paediatric Stroke Outcome Measure (PSOM). Results: Among 42 neonates, median gestational age was 39.7 weeks (IQR 38-40.7 weeks). Diagnosis occurred at a median of 1 day (IQR 0-7 days) after delivery. Twenty-seven (64%) had intraparenchymal and intraventricular haemorrhage. Mechanism was haemorrhagic transformation of venous or arterial infarction in 22 (53%). Major risk factors included congenital heart disease (CHD), fetal distress and haemostatic abnormalities. Common presentations included seizure, apnoea, and poor feeding or vomiting. Acute hydrocephalus was common. Mortality was 12%. Follow-up occurred in 36/37 survivors at a median of 1 year (IQR 0.5-2.0 years). Among 17/36 survivors evaluated in stroke clinic, 47% demonstrated neurologic deficits. Deficits were mild (PSOM 0.5-1.5) in 9/36 (25%), and moderate-to-severe (PSOM ≥2.0) in 8/36 (22%). Conclusions: In our cohort with acute HS, most presented with seizures, apnoea and/or poor feeding. Fetal distress and CHD were common. Nearly two-thirds had intraparenchymal with intraventricular haemorrhage. Over half were due to haemorrhagic transformation of infarction. Short-term neurologic deficits were present in 47% of survivors.
