[Focus on unfollowed pregnancies: history, maternal-fetal outcome and become]

In France, pregnant women's medical follow-up is a full part of the pregnancy care path, and is sometimes so dominant that it becomes, in itself, the main worrying subject for patients and physicians. When an unfollowed patient gets to the maternity hospital - an otherwise well known situation - she is often surrounded by worried expectations. However, there is no universality whether in time or space, in the pregnancy care path we strongly recommend to our patients. Until the century's beginning, our former obstetricians mostly applied hygienic and behavioral measures, and sometimes harmful cares. We can easily notice that our Europeans neighbors' or Americans' official recommendations are far from being the same as ours, with same morbidity results. Insufficient pregnancy following-up may thus recover several definitions. Medical literature about the lack of medical follow-up during pregnancy is quite limited, though national perinatal enquiries exist, like in France.
