Abstract:
We researched intrauterine fetal death (IUFD) after 22 weeks of gestation from 2009 to 2014 in our departments. During this period, there were 6236 childbirths and 35 cases (0.56%) resulted in IUFD. We researched the background and causes of IUFD in these 35 cases. The median age was 34 years and advanced maternal age accounted for 48.6% of cases, while elderly primipara accounted for 20%. There were 5 cases (14.3%) of pregnancy after fertility treatment. The median gestational age when IUFD was recognized was 30 weeks, but the gestational age in 4 cases was unclear because of lack of antenatal check-ups. The main risk factors for IUFD were maternal age over 35 (0.95% to 0.40%) and lack of antenatal check-ups (3.7% to 0.5%). The major causes of IUFD were umbilical cord abnormalities (n=10) and placental abruption (n=8), but IUFD of unknown etiology accounted for about 30% of cases. We should better inform mothers about the importance of antenatal check-ups and manage pregnancies carefully for those who have risk factors for IUFD. Furthermore, we should increase research into the causes of stillbirths.
