	'''Placenta praevia''' is a condition in [[pregnancy]] where the [[placenta]] is abnormally positioned in the [[uterus]], covering the [[cervix]] either partially or completely. This can lead to complications during [[childbirth]], as the placenta may obstruct the passage of the baby through the birth canal.

'''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 ==
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 ==
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 ==
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 ==
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 ==
Complications of placenta praevia can include [[premature birth]], [[baby in breech position]], [[Antepartum haemorrhage]], and [[postpartum haemorrhage]].
