Different types of genetic inheritance might cause placental abruption. Placental abruption can be inherited through maternal susceptibility genes for placental abruption. Alternatively, maternal alleles can be passed through the fetus or the placenta.
In this way, can you see a placental abruption on an ultrasound?
If you have any signs of a placental abruption, you'll need to go to the hospital for a complete evaluation, including fetal heart rate monitoring and an ultrasound. (An ultrasound can't necessarily detect a small abruption, but it can rule out placenta previa, the other likely cause of uterine bleeding.)
How is placental abruption diagnosed?
Diagnosis. If your health care provider suspects placental abruption, he or she will do a physical exam to check for uterine tenderness or rigidity. During an ultrasound, high-frequency sound waves create an image of your uterus on a monitor.
