Pathophysiology
Chorioamnionitis is an inflammatory condition of fetal membranes which is usually caused by infectious etiology. The pathogenesis can be further divided into 4 categories based on the anatomical route of the introduction of the microorganism:[1]
- Ascending infection might originate from the maternal genital tract (the most common route).
- Vaginal and enteric flora are usually transmitted via the ascending route to the fetal membranes.
- Iatrogenic infection might be caused by invasive procedures (e.g., amniocentesis).
- Maternal infections such as listeria monocytogenes, might infect fetal membranes through the placenta by the hematogenous route.
- In mothers with hepatic or renal diseases, the infection of fetal membranes might be originated by peritoneal infections via the route of fallopian tubes.
Gross Pathology
On gross pathology, an opaque appearance of fetal membranes is a characteristic finding of chorioamnionitis.
- Besides, the presence of opaque fetal membranes might indicate an increased risk of complications of chorioamnionitis in newborns.
