00:01 So we've talked about a lot of bleeding today. 00:04 So let's review and make sure that we've got it all down. 00:08 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. 00:22 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. 00:32 An ectopic pregnancy is an abnormal implantation of a fertilized ovum outside the uterine cavity. 00:41 In a normal pregnancy, the HCG should double about every 48 hours up to 10 weeks. 00:47 When there's an abnormal increase in HCG, that may indicate an ectopic pregnancy. 00:53 Gestational trophoblastic disease is the production and breakdown of trophoblastic tissue in the placenta. 01:00 The fetus if it's there doesn't develop beyond the primordial state. 01:05 Placenta previa occurs when the placenta attaches near or over the cervix rather than in the fundus. 01:14 An abruptio placenta occurs when there's separation of the placenta from the uterine wall before delivery of the fetus. 01:22 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. 01:35 And there are three types of vasa previa. 01:38 velamentous insertion, succenturiate lobe and battledore. 01:44 You did it, we're all done.
