Pathophysiology
The amniotic sac consists of two membranes:
- The outer membrane, the chorion, contains the amnion and is part of the placenta.
- The inner membrane, the amnion, contains the amniotic fluid and the fetus.
Chorioamnionitis is an inflammation of the chorion and amnion. It is usually caused by a bacterial infection.
Mechanisms that are responsible for chorioamnionitis are:
- Ascending bacteria from the lower genital tract (vagina, cervix) which is the most common cause.
- Prolonged rupture of the membranes which facilitates the bacteria to invade the maternal tissues.
- Invasive fetal procedures (amniocentesis, chorionic villous sampling)
- Haematgenous spread, but it is less common.
