What are Potential Problems with Placental Abnormalities?
Discussion
“The placenta is a unique organ that sits at the interface of, and facilitates nearly all interactions between, maternal and fetal physiology. It is the sole source of oxygen and nutrition for the fetus, and provides a protective barrier against external insults. The placenta is also a highly adaptable organ that is capable of showing a wide range of pathological changes in response to various maternal and fetal factors and stressors.” The placenta has 3 layers: the amnion (fetal side), the chorion, and decidua (maternal side). In addition to making observations about the maternal and fetal sides, cord variations (i.e. size, length, twists, number of vessels, insertion location) can be observed. Even with these these possible variations, most placentas are normal.
Learning Point
There are some important placental abnormalities which are clinically, and potentially critically important for maternal and fetal outcomes.
Location problems
Placenta previa is a placenta that overlies the cervical os to some extent. Those that are near but do not overlie are termed low-lying placentas.
Incidence 1:200
Diagnosis: found on routine ultrasound or painless vaginal bleeding usually in 3rd trimester
Treatment: cesarean section prior to labor, often before term
Maternal problems: hemorrhage which has its own risks such as blood transfusions, septicemia, thrombophlebitis, admission to intensive care unit, hysterectomy, maternal death
Neonatal problems: prematurity &...
