The term "margination of the placenta" refers to the condition where the placenta develops abnormally, resulting in it being attached near the edge of the uterine wall instead of the center. This abnormality can potentially cause complications during pregnancy. While "margination of the placenta" is the commonly used term for this condition, there are a few other synonyms that can be used. These include "placental marginalization", "placental margin abnormality", or even simply "marginal placenta". However, regardless of the choice of terminology, it is crucial to consult a medical professional if any signs or symptoms of this condition arise, to ensure proper management and care.
