What causes placental abruptions?

What causes placental abruptions?

High BP, trauma, ROM: Abruptio placentae (formal term) occurs when there is separation of placenta from the wall of the uterus. The diagnosis depends on there being a normally placed placenta (eg, not one covering the cervix). There may or may not be bleeding early. Common causes include high blood pressures, trauma to the abdomen, rapid loss of amniotic fluid (eg, in cases of multiple pregnancy or excess fluid). ...Read more

What's the difference between partial placenta previa and placenta previa?

What's the difference between partial placenta previa and placenta previa?

Distance form cervix: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US. ...Read more

What causes a placental abruption?

What causes a placental abruption?

Many causes: trauma, high blood pressure, drugs (cocaine), preterm labor, polyhydramnios. Can be very large or very small, so even US can miss a diagnosis.

What are the symptoms of placental abruption?

What are the symptoms of placental abruption?

Patients may or may not have vaginal bleeding. It can be dangerous as the baby may not get the same amount of oxygen and nutrients if the abruption is large. Abruption has been linked to maternal high blood pressure, Cocaine use, abdominal trauma and smoking. ...Read more

The symptoms of fetal hemorrhage?

The symptoms of fetal hemorrhage?

Fetal demise.: Fetal hemorrhage is rare but potentially lethal. The mother may not have any symptoms (except painless vaginal bleeding in case of ruptured vasa previa) but the fetus can rapidly exsanguinate and die if this dire complication occurs. Rare intracranial hemorrhage is seen in the fetal life; this can be lethal or neurologically devastating, although mild cases can even go unnoticed. ...Read more

What are the chances of prolapsed cord or placental abruption?

Incidence of : Umbilical Cord Prolapse is 1.4 -6.2/ 1000 pregnancies. Frequency of placental abruption is 1% & abruption with fetal death, 0.12%. Risk of a 2nd abruption is 4-12%; of a 3rd, 25%. There's a 40% ^ in risk of abruption for each year a woman has smoked tobacco prior to pregnancy + a higher risk of fetal demise if abruption occurs in smokers. Cocaine use ^es risk up to 35%. ...Read more

Anterior placenta previa with placental lake seen at 28w ultrasound, 2 D&Cs & no c-section hx. Any risk of placenta accreta? Best time to deliver?

Anterior placenta previa with placental lake seen at 28w ultrasound, 2 D&Cs & no c-section hx. Any risk of placenta accreta? Best time to deliver?

Placenta Previa: Placenta previa occurs when the placenta is covering the opening of the cervix. Vaginal delivery is possible in mild cases of previa. Placenta accreta is a different condition where the placenta gets "stuck" to the uterus. While the risk of accreta increases when you have previa, that risk is low if you have never had a c-section before. Follow-up with your obstetrician regarding delivery dates. ...Read more

What kind of incision for delivery of singleton in transverse lie with anterior placenta previa? Will low transverse cut risk hemorrhage/uterine tear?

What kind of incision for delivery of singleton in transverse lie with anterior placenta previa? Will low transverse cut risk hemorrhage/uterine tear?

Hyst'omy MANDATED: hello Annie-_777 I am not an OB GYN but I have had a lot of experience which tells me that a lower abdominal incision (Pfannen-Stiel) is a better incision in almost all situations. This situation of a transverse lie and an anterior placenta praevia is a very hazardous situation because you need the baby out and the cord clamped within seconds of opening the uterus so choose a very skilled surgeon. ...Read more

It is a serious pregnancy complication! seek mfm care. ...Read more
