Introduction. Post — hemorrhagic hydrocephalus (PHH) is a severe complication of intraventricular hemorrhage (IVH) in extremely preterm infants, significantly worsening survival rates and neurodevelopmental outcomes. Objective. To analyze current literature (2015–2025) on the pathogenesis, diagnosis, treatment approaches, and outcomes of PHH in preterm infants. Materials and Methods. This review is based on an analysis of peer — reviewed publications, clinical guidelines, and results of randomized trials addressing PHH. Results. The development of PHH involves a complex interplay of mechanisms: mechanical obstruction of cerebrospinal fluid (CSF) pathways by blood clots, neurotoxic effects of hemoglobin breakdown products and iron, as well as neuroinflammation and meningeal fibrosis. The main diagnostic tool is cranial ultrasonography, which allows assessment of IVH severity and progression of ventriculomegaly; MRI is used as a supplementary method. Treatment options include temporary decompression measures (ventricular taps, reservoirs, subgaleal shunts) and permanent CSF shunting (ventriculoperitoneal shunt). Recently, endoscopic techniques (neuroendoscopic lavage, endoscopic third ventriculostomy with choroid plexus coagulation) have been actively investigated. Despite advances in neonatal care, long — term outcomes remain poor: up to 40–50 % of children develop severe disability, mainly due to periventricular leukomalacia. Conclusion. PHH in preterm infants requires a multidisciplinary approach and early intervention. Prevention of severe IVH remains the cornerstone of prophylaxis. Promising future directions include the development of neuroprotective strategies and the refinement of minimally invasive surgical techniques.
