Restriction of the mother's blood flow through the placenta is the most common cause of placental insufficiency. Any restriction can have a serious effect upon fetal growth and development. Placental damage can cause restriction - damage for example caused by infarction (tissue death) or the separation from the uterine wall (placenta abruption). Spasm or blood clots in the placenta veins also have the same effect.
Certain genes might be missing that are necessary for continued development, or extra copies of certain genes (or chromosomes) might cause the baby or placenta to not grow properly. This could explain why some certain types of chromosomal abnormalities lead to miscarriage while others do not.
