Is placenta previa hereditary?

no. Placenta previa is an obstetric complication in which the placenta is inserted partially or wholly in lower uterine segment.It can sometimes occur in the later part of the first trimester, but usually during the second or third. It is a leading cause of antepartum haemorrhage (vaginal bleeding). It affects approximately 0.4-0.5% of all labours.
Not genetic. 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.

What are the tests for placenta previa?

This can cause problems during the birth process because when the cervix starts dilating it could tear the blood vessels in the placenta, depriving the baby of blood and making mom lose too much blood. To be safe, many ob's recommend a c-section instead of vaginal birth. Read more...
Placenta problem. Placenta previa occurs when the placenta blocks the cervical os, the exit from the uterus. Typically need c-section. Vaginal bleeding can be severe enough to require transfusion. If get previa after previous c-section, risk for accreta -placenta growing into uterine wall- increases for each past c/s. This may need c-section + hysterectomy, which can be very dangerous due to high blood loss. Read more...
