Placenta praevia
Placenta praevia is a condition in pregnancy where the placenta attaches itself in the lower part of the uterus near to or covering the cervix. It is a leading cause of Antepartum haemorrhage (bleeding in late pregnancy).
Causes[edit | edit source]
The exact cause of placenta praevia is unknown, but it is more common in women who have had a previous Caesarean section, a higher number of pregnancies, are older, and in those who smoke or have had a surgical procedure on their uterus such as a Dilation and curettage.
Symptoms[edit | edit source]
The main symptom of placenta praevia is painless bleeding from the vagina during the second half of pregnancy. Other symptoms may include premature birth and baby in breech position.
Diagnosis[edit | edit source]
Placenta praevia is usually diagnosed during a routine Ultrasound scan in the second trimester of pregnancy. If placenta praevia is suspected, a follow-up scan is usually performed at 32 weeks.
Treatment[edit | edit source]
The treatment for placenta praevia depends on the extent of the placenta covering the cervix and the gestational age of the fetus. If the placenta is completely covering the cervix, a Caesarean section is usually performed. If the placenta is not completely covering the cervix, a vaginal delivery may be possible.
Complications[edit | edit source]
Complications of placenta praevia can include premature birth, baby in breech position, Antepartum haemorrhage, and postpartum haemorrhage.
