A very rare
complication is bleeding infiltrating the myometrium
that results in condition called Couvelaire’s uterus [42].
In case of placental abruption, the frequency of maternal
death increases seven fold. The adverse effects for the
fetus include preterm delivery, low birth weight, low
Apgar scores, perinatal asphyxia and death [7, 8]. Recently
decreasing perinatal mortality in placental abruption
nowadays amounts to approximately 12%. Almost
80% of perinatal deaths are intrauterine [9]. Although
obstetricians have wide and detailed knowledge on the
risk factors of placental abruption, still in most of the
cases it is very hard to establish its cause.
