[Birth injuries to the liver in deceased newborns in relation to the means of delivery].

The study includes all 151 deceased newborns with traumatic subcapsular haemorrhage of the liver for the 3-year period between 1992 and 1994 in the University Maternity Hospital "Maĭchin dom"--Sofia. We compared the frequency and the causes for the hepatic rupture and how they depend on the way of delivery. We established a significantly higher frequency in the group of neonates undergone breech delivery /17.2%/ then in the group with head presentations /5.7%/. In the last group 3 of neonates were born by caesarean section. We conclude that the breech presentation increases the risk of hepatic birth injuries. Other predisposing factors are the perinatal asphyxia and the immaturity.
