Extensive intraventricular hemorrhage (IVH) in very preterm newborns (VPNB) is associated with mortality and severe long-term neurological sequelae. Objectives : To know the most frequent neurological pathologies associated with extensive IVH, to determine the functional outcomes of mobility in the motor area and intellectual capacity in the cognitive area, to analyze the association between both areas and to know the schooling achieved. Patients and Method : Descriptive and longitudinal study in VPNB with extensive IVH born between 2001 and 2014. They underwent protocolized neurological follow-up until school age. The functional outcomes in mobility and intellectual capacity were categorized into 4 levels: level 1 corresponds to good functionality and autonomy; level 2, functionality that allows independence, with support in some tasks; level 3 requires constant external support; and level 4 where there is total dependence. The association was analyzed using Chi-square and Cramer's V coefficient. Results: 74 children completed the follow-up; the most frequent associated neurological pathologies were neurodevelopmental disorders, hypertensive hydrocephalus, and epilepsy. Independent mobility (normal or with limitations) reached 74.4% while 24.3% used wheelchairs. 51.3% was categorized as normal to borderline intellectual range, 12.2% as mild intellectual disability (ID), 17.6% as moderate ID, and 19.9% as severe to profound ID. There was a strong statistical association between functional levels of mobility and intellectual capacity (p < 0.000 and V = 0.62). Schooling was proportional to intellectual capacity: 56.8% attended regular schools, 27.0% attended special schools, and 16.2% had no schooling. Conclusions : 2/3 VPNB with extensive IVH showed positive functional outcomes, from normal to mild limitations that allow an almost autonomous life; in 1/3 the outcomes were unfavorable in mobility and cognitive performance, and there was a strong statistical correlation between both areas studied. Schooling was consistent with the intellectual level.
