AbstractIntraventricular hemorrhage and the subsequent development of posthemorrhagic hydrocephalus (PHH) is one of the most serious complication of prematurity, especially in extremely low birth weight infants.1 Neurodevelopmental delay, epilepsy, and severe cognitive impairment represent common sequelae of PHH.2,3 A ventriculoperitoneal shunt insertion in such premature infants is associated with higher rates of skin erosion, infection, and shunt failure.4 One therapeutic option is represented by the use of temporary cerebrospinal fluid diversion procedures (such as external ventricular drainage, subcutaneous reservoir, and ventriculosubgaleal shunt) to gain time avoiding the PHH secondary damages.5,6 An extremely low birth weight (birth weight = 653 g) infant at 24 + 4 gestational age weeks presented with a grade III intraventricular hemorrhage and periventricular hemorrhagic infarction 5 days after birth. Serial transfontanellar ultrasound disclosed a progressive PHH. Progressive symptomatic PHH, pulmonary hemodynamic instability, and suboptimal general prematurity conditions were the main factors that led to plan a percutaneous transfontanellar ultrasound-guided external ventricular drainage at the neonatal intensive care unit. The illustrated procedure represents a bedside minimally invasive, effective, reversible, and sparing-time choice alternative to other temporary cerebrospinal fluid diversion techniques. This edited, 2-dimensional operative video highlights the key surgical steps of the proposed procedure (Video 1). All relevant patient identifiers have been removed from the video.
