Slide 181: Amniotic membranes and umbilical
cord with acute amnionitis
 |
The coiled up thing to
the far left is a section of amniotic membrane. Look at the margin
of the membrane and the decidua for the acute inflammatory infiltrate.
In the case of the umbilical cord, the acute inflammatory cells will be
found in the walls of the vessels.
See this slide with the
virtual microscope. |

Here we see the great
number of PMNs in the decidualized endometrium and amniotic membranes.
Under normal circumstances, there should be none. The inflammation is due
to an infection resulting from the prolonged period the amniotic membranes
were ruptured. If delivery of the baby is very prolonged, it could
lead to endometritis for the mother and a systemic infection for the newborn. |
