Abstract: | The paper gives the results of a morphological investigation using ventricular system embedding, organometry, light and electron microscopies, histostereometry and immunohistohemistry of brains from 50 fetuses and neonatal infants of 22-27 weeks gestation. The comprehensive investigations revealed the morphological features of intrauterinally acquired ventriculomegaly, which reflect tissue immaturity of the parenchyma and the vascular component of the brain. |
