What causes Placenta Abruption?
One of the commonest reason for placental separation
is uncontrolled raised blood pressure or hypertension.
Other reasons include a severe blow to the abdomen (a
fall, during a car crash or abuse) smoking, drinking,
sudden rupture of membranes and when the mother has
auto-immune diseases. However in more than half of abruption
cases, there are no obvious medical reasons.
Complete abruption is understandably life-threatening
for the fetus and sometimes the mother. In partial abruption
the threat is less serious in the mother unless she
has a hemorrhage or shock to deal with but it is a critical
time for the fetus. Again, the distress or injury to
the fetus is dependent on how much of the placenta has
detached from the uterus wall.
