[Intraventricular hemorrhage and periventricular leukomalacia in low birth-weight neonates in three hospitals in Lima, Peru]

To describe the frequency and severity of intraventricular hemorrhage and periventricular leukomalacia in low birth-weight neonates in three hospitals in Lima, Peru, 385 newborn babies weighing under 2,000 g at birth were evaluated between May 2012 and July 2014. Brain ultrasounds were obtained at 40 weeks' gestation, 3-5 days of life, and 3-4 weeks of life. Intraventricular hemorrhage occurred in 19.2% of neonates weighing under 1,500 g and was severe (grade III or with periventricular hemorrhagic infarction) in 9.6% of neonates under 1,500 g. Mortality in infants with intraventricular hemorrhage was 47.1%, while periventricular leukomalacia was found in 5.4% of neonates 1,500 g and under; both diagnoses were more frequent in lower-weight babies. The frequency of intraventricular hemorrhage is similar to that reported in other countries; however, severity and mortality are greater.
