SILVEIRA, Rita C. and PROCIANOY, Renato S.. Ischemic brain damage in very low birth weight preterm newborn infants. J. Pediatr. (Rio J.) [online]. 2005, vol.81, n.1, suppl.1, pp. S23-S32. ISSN 1678-4782. http://dx.doi.org/10.1590/S0021-75572005000200004.
OBJECTIVE: To present a critical and up-to-date review of ischemic brain damage in premature, very low birth weight infants. SOURCES OF DATA: Articles were obtained by means of a search of the MEDLINE database, with those considered most representative by the authors being selected. SUMMARY OF THE FINDINGS: The most frequent ischemic injuries among preterm, very low birth weight neonates are hemorrhage progressing to with ischemic brain damage, cystic periventricular leukomalacia and diffuse lesions of the cerebral white matter. All of these conditions have multiple causative factors, which may include vascular, hemodynamic, inflammatory and infectious factors. These are disorders that can cause significant neuropsychomotor sequelae and lead to cerebral palsy and/or cognitive and behavioral deficits. CONCLUSIONS: Early diagnosis and adequate management of the patient can minimize long-term problems caused by cerebral ischemic injuries. Prevention of premature labor and delivery is the most important prophylactic measure.
