So we've talked about a lot of bleeding today.
So let's review and make sure
that we've got it all down.
So in a nutshell, a spontaneous abortion
is a pregnancy that ends prior to 20 weeks
or in the cases when we don't know the gestation
that we have a weight of the products of conception
of greater than 550 grams.
A type of abortion is going to be
determined by the viability of the fetus,
the dilation of the cervix and whether
or not the membranes are ruptured.
An ectopic pregnancy is an abnormal implantation
of a fertilized ovum outside the uterine cavity.
In a normal pregnancy, the HCG should
double about every 48 hours up to 10 weeks.
When there's an abnormal increase in HCG,
that may indicate an ectopic pregnancy.
Gestational trophoblastic disease is the production
and breakdown of trophoblastic tissue in the placenta.
The fetus if it's there doesn't
develop beyond the primordial state.
Placenta previa occurs when the placenta attaches
near or over the cervix rather than in the fundus.
An abruptio placenta occurs when there's
separation of the placenta from the uterine wall
before delivery of the fetus.
A vasa previa is a condition in which the fetal
umbilical vessels implant in the membranes
or on the sides of the placenta,
rather than the center of the placenta.
And there are three types of vasa previa.
succenturiate lobe and battledore.
You did it, we're all done.
