OBJECTIVES: Fetal macrosomia is defined as a fetus that is of large size for gestational age, i.e. equal to or greater than the 90th percentile of weight. There is some evidence of increased perinatal mortality and morbidity rates in cases of macrosomia.

DESIGN: This is a retrospective study of patients with term pregnancy. We analyzed the deliveries of 508 infants born with birth weight ≥ 4 200 grams and considered them as a study group. The deliveries of newborns with birth weight less than 4 000 g constituted the control group (330 cases). Maternal and neonatal medical records were retrospectively reviewed for clinical data.

SETTING: The study was conducted in Second Department of Obstetrics and Gynecology Warsaw Medical University from January 2004 to December 2007.

RESULTS: Maternal age, parity, BMI and pregnancy weight gain were positively related to fetal macrosomia. Prolonged first stage of labor, cesarean section rate and increased blood loss were observed more frequent in macrososmia. There were no differences between both groups according to Apgar score and neonatal birth trauma. Macrosomia was observed more frequent in male fetuses. Our data showed that careful qualification to way of delivery let us achieve the same good outcome in macrosomia.

CONCLUSIONS: Older obese multiparas are at increased risk of having macrosomic baby. The increased incidence of cesarean section in these women is due to cephalo-pelvic disproportion or obstructed labor. Macrosomia is more often in male fetuses....

Comparative Study 2010; 31(3): 384-389 PubMed PMID: 20588249 Citation  Keywords:  Adult, Apgar Score, Cesarean Section:statistics & numerical data, Female, Fertilization, Fertilization in Vitro, Humans, Infant, Newborn, Male, Pregnancy, Pregnancy Complications:epidemiology, Pregnancy Trimester, Second, Pregnancy Trimester, Third, Pregn.   

BACKGROUND: Most authors agree that the twin pregnancies have a higher risk of complications compared to singleton pregnancies. However, there is no unanimity as to whether the risk of complications in twin pregnancies resulting from in vitro fertilization is higher than in twin pregnancies resulting from spontaneous conception.

OBJECTIVE: The aim of this study was to estimate the frequency rates of complications in the second and third trimester of dichorionic-diamniotic twin pregnancies resulting from IVF (group I) compared to dichorionic-diamniotic and monochorionic-diamniotic twin pregnancies resulting from spontaneous conception (group II and III).

RESULTS: The rate of cesarean section and cervical cerclage was significantly higher in the group I. Polyhydramnios occurred less frequently in group I than in group III. The discordant growth of fetuses occurred significantly more frequently in the group I. The frequency of other complications did not differ in the studied groups. The Apgar score was similar in the group I and II but significantly lower in the group III compared to the group I.

CONCLUSIONS: 1) The frequency of complications in twin pregnancies after IVF is similar to those in the twin pregnancies conceived spontaneously. 2) In the twin pregnancies after IVF it is necessary to expect only a higher frequency of caesarean sections, cervical incompetence and a discordant growth of the twins when comparing with twin pregnancies conceived spontaneously. 3) In the twin pregnancies after IVF the intrauterine fetal demise and polyhydramnios occurred less frequently than in monochorionic-diamniotic pregnancies after spontaneous conception....
