Hemorrhagic periventricular leukomalacia in the neonate: a real-time ultrasound study. Two major factors appear to be involved in the development of PVL: (1) decreased blood or oxygen flow to the periventricular region (the white matter near the cerebral ventricles) and (2) damage to glial cells, the cells that support neurons throughout the nervous system. official website and that any information you provide is encrypted PVL is also the most common cause of cerebral palsy in preterm infants. Premature infants often exhibit visual impairment and motor deficits in eye control immediately after birth. Leuko refers to the white matter of the brain. The site is secure. PVL is injury to the white matter around the fluid-filled ventricles of the brain. These are the spaces in the brain that contain the cerebrospinal fluid (CSF). Periventricular leukomalacia: MedlinePlus Medical Encyclopedia It is proposed that the prolonged hypoxia and ischemia produce a "no reflow" phenomenon causing brain edema (more pronounced in the white matter); this resulted in infarctions of white matter in the periventricular arterial end and border zones. [6][8] Many patients exhibit spastic diplegia,[2] a condition characterized by increased muscle tone and spasticity in the lower body.
