Subependymal hemorrhage (SEH) occurs with a hypoxic-ischemic injury especially in preterm infants. We assessed the visualization of the branches of the deep veins in infants with SEH according to SEH grade. We found more frequently impaired branches of the medullary veins in infants with SEH-Grade IV. On the contrary, SEH with lower grade showed less frequent relation to the impairment of the medullary veins. SEH with parenchymal hemorrhage may be accompanied with more frequent impairment of the branches of the medullary veins.
