Brain changes in newborns, infants and children with congenital heart disease in association with cardiac surgery. Additional observations

Journal of Neurology
K L Terplan


The histopathologic pattern in the Central Nervous System in 12 out of 21 new-borns and young infants, below 2 months of age, operated for various congenital heart defects, is that of recent necroses in the deep and subcortical white matter of the pallium, seen from a few hours to 8 days following completion of surgery. Type and location of these lesions of ischemic coagulative necrosis, resembling findings in the perinatal respiratory distress syndrome, seem to depend on shock-like states, the low output syndrome of the left heart with hypovolemia and hypotension. The cause of death in all these infants was cardio-respiratory failure. The question to what extent glial scars replacing necroses within the mostly non-myelinated fiber systems of the pallium will lead to defective maturation of the brain in later infancy and childhood remains a challenge for neurologic and psychological investigation, even if the heart defect has been successfully repaired by the surgeon. Post-mortem data of the CNS in 24 older infants and children below 9 years of age in association with cardia surgery include thrombembolic infarctions, also, after catheterization alone, diffuse or segmental cortical necroses, and cortical scars, especially in chi...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
