[Delivery of twin pregnancy and materno-fetal prognosis in a level 3 Tunisian University Center: a retrospective study about 399 cases].

Despite obstetric and pediatric progress, twin pregnancy still represents nowadays a high-risk situation for both pregnancy and childbirth. It still remains a distressing situation for the obstetric team. The aim of this study was to describe the practice of twin pregnancy deliveries in the obstetrics and gynecology department of Sousse, the maternal and fetal prognosis and to analyze the factors that may influence it. A descriptive, retrospective study of twin pregnancies births was conducted over a period of two years. We included twin pregnancies that have reached at least 28 weeks of amenorrhea (SA) and women having a twin pregnancy complicated by fetal death in utero. Women with a twin pregnancy who gave birth before 28 weeks were excluded. Bi-chorionic bi-amniotic pregnancies represented 67% of cases, compared with only 11.5% of mono-chorial bi-amniotic pregnancies and 3% of mono-chorial mono-amniotic pregnancies. A total of 52 patients have scheduled caesareans. Spontaneous labor was noticed in 304 cases, and was initiated in 43 cases. A total of 178 women gave birth by vaginal delivery (44.6%) and 215 by cesarean (53.9%). The cesarean rate for the second twin was 1.5%. When the delivery was vaginal, 19 cases of complications were observed (10.7%). We analyzed the Apgar score of both the first and the second twin according to the mode of delivery. There was no statistically significant difference in the Apgar score between the two delivery routes. Perinatal morbidity and mortality is higher for the second twin than for the first twin. Maternal morbidity was higher in vaginal delivery than cesarean delivery. There are no significant differences in the Apgar score according to whether the infants were born by vaginal delivery or by caesarean.
