Neurosonographic and biochemical correlates of periventricular leukomalacia in low-birth-weight infants.
The incidence of periventricular leukomalacia (PVL) was investigated by ultrasound in a group of 119 consecutively scanned low-birth-weight infants during a period of 3 years. The overall incidence of PVL was 6.7% while the incidence of peri-intraventricular hemorrhage was 44.5%. Ultrasound evidence of posthemorrhagic lesions was seen early and related strongly to follow-up findings. Evidence of cystic degeneration appeared later. The presence of PVL was confirmed by computed tomography at 5 months of age and anticipated by serial measurements of creatine kinase brain isoenzyme performed in the first 60 h of life. A significant correlation was observed between neurosonographic findings of PVL and high cord blood values of enzymatic pattern (p less than 0.02). Both were correlated with poor neurodevelopmental outcome at 12 months corrected age.
