What may occur as a consequence of a succenturiate lobe of the placenta?

A succenturiate lobe of the placenta refers to an accessory lobe that is separate from the main placental mass. This condition can lead to complications, particularly during delivery. One significant concern with a succenturiate lobe is the potential for retained placental tissue after birth. If this lobe is not delivered along with the main placenta, it can remain within the uterus, leading to incomplete placental expulsion.

The retention of placental tissue can result in several issues, notably postpartum hemorrhage due to the uterus failing to contract effectively, as it still recognizes a part of the placenta as being present. This retained tissue can also lead to infection if not addressed promptly. Thus, managing the delivery and ensuring that all components of the placenta are accounted for is vital to prevent these complications.

Other options, such as fetal heart rate irregularities or increased maternal blood pressure, may be related to various other factors during pregnancy or labor but are not direct consequences of having a succenturiate lobe. Similarly, decreased amniotic fluid is not directly associated with this placental anomaly. The primary concern revolves around the risks of retained placenta and subsequent hemorrhage, making this the correct choice.
