Abstract

The hemorrhages found in mature infants differ from those of prematures in distribution and pathogenesis. Hemorrhages in prematures (cf. Chap. 4) are mainly subependymal, intraventricular, leptomeningeal, or in the cerebellar parenchyma. They are related to asphyxia and they become less frequent with maturity. Hemorrhages in the mature newborn often relate to mechanical trauma, such as lacerations of the tentorium, falx or large venous channels, subdural hematomas, or injuries of the spinal cord. Hemorrhagic disease of the newborn is another factor. The present chapter also includes the pathology of herniations from increased intracranial pressure in the newborn.
