[Analysis of perinatal death at the Institute of the Health Center of the Polish mother in 1995, 1996 and 1997. The reason for making changes in the accountability for perinatal death].

: Perinatal death's causes of fetuses and newborns from single and twin pregnancies delivered at the PMMHI from 1995-1997 were discussed. Data from the Pathology Department were analysed and compared to information regarding prenatal US + ECHO diagnoses coming from the Department for Diagnoses of Congenital Malformations at the PMMHI. The most frequent cause of death of fetuses and newborns from single pregnancies were congenital malformations (42%). In twins there prevailed such typical for multiple pregnancies' death causes as TTTS (27%), intrauterine demise of one of the twins (17%). Premature labor occupies the second most frequent cause of death both in single and multiple pregnancies. Most of perinatal deaths may be predicted prenatally by means of ultrasound and fetal echocardiography.
