Fig. 1 From:Outcomes of the 2019 hydrocephalus association workshop, "Driving common pathways: extending insights from posthemorrhagic hydrocephalus" Posthemorrhagic hydrocephalus of prematurity is a complex medical condition with intricate, developmentally regulated pathophysiology. Defined by disruption to cerebral spinal fluid dynamics through unique cellular and molecular mechanisms, novel, non-surgical treatment approaches address inflammation, fluid dynamics, choroid plexus, ependyma, cilia, and the glymphatic system in concert.
