The enormous progress that has been made in prenatal medicine in recent years has resulted in the emergence of a number of new diagnostic and therapeutic methods that allow increasingly early detection and treatment of many fetal malformations - treatment in utero, i.e. before birth.
Fetal surgery carries a very high risk of a number of postoperative complications for both mother and foetus. The most common complications of such specific operations are premature births, premature rupture of the fetal bladder and all the consequences thereof, i.e. intrauterine infection, thrombocephaly, fetal pulmonary oedema, intrauterine fetal necrosis and others. A pregnancy during which intrauterine correction of a foetal defect has been performed is terminated by caesarean section. This places an additional burden on the mother, as two operations are required in a short period of time.
