Abstract

Abstract : The aim of the present study was to perform a meta‐analysis of published data to determine the significance of clinical factors and exposures to the risk of perinatal arterial ischaemic stroke (PAIS) and provide guidance for clinical diagnosis and treatment. A comprehensive literature search of the PubMed, Embase, MEDLINE and Cochrane Library databases for relevant observational studies (cohort/case−control) from March 1984 to March 2016 was undertaken. Two review authors independently examined the full text records to determine which studies met the inclusion criteria and evaluated risk factors for PAIS. Risk ratios, odds ratios and 95% confidence intervals were estimated. A total of 11 studies were included in the analyses. Intrapartum fever >38°C, pre‐eclampsia, oligohydramnios, primiparity, forceps delivery, vacuum delivery, fetal heart rate abnormalities, abnormal cardiotocography tracing, cord abnormalities, birth asphyxia, emergency caesarean section, tight nuchal cord, meconium‐stained amniotic fluid, umbilical arterial pH <7.10, Apgar score at 5 min <7, resuscitation at birth, hypoglycaemia, male gender and small for gestational age were identified as risk factors for PAIS. This systemic review and meta‐analysis provides a preliminary evidence‐based assessment of the risk factors for PAIS. Patients with any of the risk factors identified in this analysis should be given careful consideration to ensure the prevention of PAIS. Future studies focusing on the combined effects of multiple prenatal, perinatal and neonatal risk factors for PAIS are warranted.
