Question

What percentage of third trimester bleeds are due to placental abruption?

a) Less than 10%
b) Around 25%
c) Approximately 50%
d) More than 75%

Answer 1

Placental abruption accounts for around
`25%` of third trimester bleeding in pregnancy, which is answer (b).

Step-by-step explanation:

When discussing the causes of third trimester bleeds in pregnancy, it is essential to understand the role of the placenta and associated complications that can arise. One such complication is placental abruption, which refers to the premature separation of the placenta from the uterus. Another cause of third trimester bleeding is placenta previa, where the placenta covers the cervix.

However, placenta previa accounts for only
`0.5` percent of pregnancies. Specifically addressing placental abruption, it accounts for around
`25%` of third trimester bleeds, making answer choice (b) the most accurate one.
