Monochorionic (MC...

OBJECTIVE To investigate whether the outcome of a pregnancy is related to the time required to achieve that pregnancy (TTP). DESIGN The distribution of the TTP for pregnancies ending in multiple birth, early (before week 12) and late (weeks 12-28) miscarriage, stillbirth, and extrauterine pregnancy was compared to that of pregnancies ending in singleton birth. Furthermore, the distribution of...
Background: The transfer of multiple embryos during ART procedures (IVF/ICSI) in order to maximize the chance of pregnancy, has resulted in increasing rates of multiple pregnancies with a 20- fold increased risk of twins and 400- fold increased risk of higher order pregnancies with significantly high maternal and perinatal morbidity and mortality in comparison with singleton. Since at pres...
OBJECTIVE To investigate the maternal serum concentration of human placental growth hormone (hPGH) in trisomy 21 and trisomy 18 pregnancies at 11 to 13 weeks of gestation and to examine the possible association between fetal nuchal translucency (NT) thickness and maternal serum free beta-human chorionic gonadotrophin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A).

RESULTS: In total, 615 cases were detected. The incidence of venous thromboembolism was 1 per 1000 pregnancies. The anteand postnatal incidences were quite similar. Antenatal risk factors were assisted reproduction, gestational diabetes, age older than 35 years, multiple pregnancies, and primi-parity. Postnatal risk factors were cesarean section, preeclampsia, assisted reproduction, abruptio pl...
