In this population at high risk of adverse outcomes, including intraventricular haemorrhage and white matter injury, as well as longer-term neurodevelopmental impairment, it is challenging to attribute sequelae to the PDA. Moreover, individual patient characteristics including gestational age and timing of PDA intervention factor into risks of brain injury. Haemodynamic assessment of the ductus combined with bedside neuromonitoring techniques improve our understanding of the role of the PDA in neurological injury. Effects of various PDA management strategies on the brain can similarly be investigated. This review incorporates current understanding of how the PDA impacts the developing brain of preterm infants and examines modalities to measure these effects. ER -
