In 2012, the American College of Obstetricians and Gynecologists officially endorsed delaying clamping of the umbilical cord for 30 60 seconds with the newborn held below the level of the placenta in all cases of preterm delivery based largely on evidence that it reduces the risk of intraventricular hemorrhage in these children by 50 %.

Environmental events associated with macrocephaly include infection, neonatal intraventricular hemorrhage ( bleeding within the infant brain ), subdural hematoma ( bleeding beneath the outer lining of the brain ), subdural effusion ( collection of fluid beneath the outer lining of the brain ), and arachnoid cysts ( cysts on the brain surface ).

The causes are usually genetic but can also be acquired and usually occur within the first few months of life, which include 1 ) intraventricular matrix hemorrhages in premature infants, 2 ) infections, 3 ) type II Arnold-Chiari malformation, 4 ) aqueduct atresia and stenosis, and 5 ) Dandy-Walker malformation.

This scale has been modified by Claassen and coworkers, reflecting the additive risk from SAH size and accompanying intraventricular hemorrhage ( 0-none; 1-minimal SAH w / o IVH; 2-minimal SAH with IVH; 3-thick SAH w / o IVH; 4-thick SAH with IVH );.
