Amnionicity refers to the number of amniotic sacs present in a multiple gestation pregnancy, a critical factor in OBGYN ultrasound. This distinction, determined early in gestation, classifies twin pregnancies as monoamniotic (one sac) or diamniotic (two sacs), profoundly impacting management and potential complications. Early and accurate assessment of amnionicity is crucial for guiding prenatal care and monitoring.
Ultrasound plays a vital role in identifying amnionicity by visualizing the dividing membrane. Accurate determination helps healthcare providers anticipate and manage risks such as cord entanglement in monoamniotic pregnancies, optimizing fetal outcomes. This key OBGYN ultrasound parameter is fundamental for comprehensive twin pregnancy assessment and management.
