IVH is particularly associated with prematurity.
It occurs in up to 50 percent of babies of <1,500 gm. birthweight and is rare in mature babies.
Other risk factors are respiratory distress syndrome and the need for ventilatory support, hypercapnia and metabolic acidosis.
Coagulation defects also contribute.
Most affected babies have minimal clinical signs.
At the other extreme, the
