Prof. Mirosław Wielgoś, MD, Rector at the Medical University of Warsaw, talks about why women of all ages should undergo prenatal testing and where they can turn for help.

Maternal-fetal medicine is a dynamically developing field, which enables not only to diagnose and treat maternal diseases but also condtions of an unoborn child developing in a womb. Fetal therapy is a highly specialized branch of maternal-fetal medicine which offers surgeries before birth. Prenatal intervensions aim to correct or diminish unfavorable effects of a fetal congenital defect. However, the starting point for a succesful intrauterine therapy is always a thorough prenatal diagnosis and an extensive knowledge regarding fetal pathophysiology in each case. Fetal surgery is now an established but still rapidly evolving specialty, born from the rationale that destructive embryologic processes, recognized early in gestation, can be curtailed by prenatal correction. Prenatal surgical techniques have evolved from highly invasive interventions involving hysterotomy to minimally- invasive fetoscopic interventions. However, there is still space for research aiming to find solutions including pharmacological treatment. In this review we aimed to present various conditions in which fetal surgery has been attempted and the present the current status of this specialty.
