PVL is overdiagnosed by neuroimaging studies and the other white matter lesions of the brain are underestimated. Periventricular leukomalacia, or PVL, is a type of brain damage that involves the periventricular white matter of the brain. leukomalacia: ( l-k-m-l'sha ), Disorder involving softening of brain white matter. However, the correction of these deficits occurs "in a predictable pattern" in healthy premature infants, and infants have vision comparable to full-term infants by 36 to 40 weeks after conception. As previously described, the highest frequency of PVL is seen in premature, very low birth weight infants. Researchers have begun to examine the potential of synthetic neuroprotection to minimize the amount of lesioning in patients exposed to ischemic conditions.[15]. Periventricular leukomalacia (PVL) is a form of white-matter brain injury, characterized by the necrosis . [11] These cytokines are toxic to the developing brain, and their activity in an effort to respond to specific areas of damaged tissue is believed to cause "bystander damage" to nearby areas that were not affected by the original insult. PVL is injury to the white matter around the fluid-filled ventricles of the brain. Leuko means white. These are the spaces in the brain that contain the cerebrospinal fluid (CSF). The classic neuropathology of PVL has given rise to several hypotheses about the pathogenesis, largely relating to hypoxia-ischemia and . Accessibility Carbon monoxide intoxication was excluded.
