| Research Abstract |
Advances in obstetric technology and neonatal intensive care such as fetal heart rate monitoring or phototherapy have certainly contributed to the recent reduction in the incidence of cerebral palsy. This significant decrease was mainly related to the syndrome of a spastic hemiplegia and tension athetosis, both of which concern perinatally acquired forms of cerebral palsy.Etiology and pathogenesis of cerebral palsy are of course very hetrogeneous conditions. However, their pathogenosis is not clearly resolved. In pathogenosis of remained brain damage followed by prematurity, intraventricular hemorrhage which is a frequent cause of morbidity arises mostly from subependymal hemorrhage, rarely from hemorrhages in periventricular white matter or choroid plexus. These periventricular-intraventricular hemorrhages are actually vascular accidents based on vascular immaturity. In addition to predisposing pathogenetic factors of anatomical and hemodynamic immaturity there are important causing factors which induce cerebral hypoperfusion and hyperperfusion accompanied with venous pressure increase. The continuous monitoring of periventricular CBF and venous pressure may elucidate the mechanism of early or late onset of subependymal hemorrhage / intraventricular hemorrhage or their progression.
