RESUMO
OBJECTIVE: To report the incidence of fetal and maternal complications after selective fetoscopic laser surgery for twin-to-twin transfusion syndrome (TTTS). METHODS: A total of 150 cases of TTTS were treated from January 2004 to June 2009 (period 1, 2004-2006, 62 cases; period 2, 2007 to June 2009, 88 cases). Fetal complications (double and single intrauterine fetal death, recurrence of TTTS, twin anemia-polycythemia sequence (TAPS), reversal of TTTS, cerebral lesions in one twin) and maternal complications were recorded, and retrospectively analyzed. RESULTS: Nineteen (12.6%), 58 (38.7%), 61 (40.7%) and 12 cases (8.0%) were classified preoperatively as Quintero stage I, II, III and IV, respectively. The anterior placenta was described in 73 cases (48.6%). Double and single fetal death occurred overall in 7.3 and 36.0% of cases, respectively. The rate of recurrence was 11.3%, of TAPS 3.3%, and of reversal of TTTS 1.3%. Cerebral lesions were diagnosed in 3 donors (2.0%). Eighteen cases (12.0%) of fetal complications had a second procedure (6 repeat laser, 4 serial amnioreduction, 8 bipolar cord coagulation). Pregnancies undergoing a second procedure delivered at a median gestational age of 30.2 weeks compared to 32.1 weeks for those not repeating (p = 0.04). Perinatal survival of at least one twin improved from 66.1 to 79.5% (p = 0.06) in the two consecutive periods. For every 10 laser surgeries performed, there was an average improvement of 1.5% in the predicted percentage of survival of at least one twin (OR 1.09, 95% CI 1.00-1.19). Major maternal complications occurred in 9 cases (6.0%), 3 of which required admission to intensive care unit. CONCLUSIONS: Fetal complications are common after fetoscopic laser surgery. In this experience, an increasing number of procedures improved the performance of a new fetoscopic laser center.

OBJECTIVE: To review the experience of performing selective feticide with bipolar cord coagulation (BCC) in complicated monochorionic (MC) twin pregnancies at a single center. METHODS: This was a retrospective analysis of BCC performed using 3-mm bipolar forceps under ultrasound control in cases complicated by twin-to-twin transfusion syndrome, selective growth restriction, discordant anomaly or twin reversed arterial perfusion sequence. RESULTS: The series comprised 118 cases with a median gestational age at the time of the procedure of 22 (range, 16-30) weeks. There were 14 (12%) intrauterine deaths of the cotwin, eight (7%) miscarriages and one (1%) termination of pregnancy. When BCC was performed before 19 weeks of gestation, the rate of miscarriage was 45%, whereas it was 3% (P < 0.001) when BCC was performed after 19 weeks. Preterm prelabor rupture of membranes (PPROM) occurred in 45 (38%) cases. The median interval between BCC and PPROM was 4 (interquartile range, 2-9) weeks. In 15 (13%) cases, PPROM occurred within 2 weeks after the procedure. Median gestational age at delivery was 34 (range, 24-41) weeks. The median birth weight was 2103 (range, 480-3875) g. Neonatal death occurred in 11 (9%) cases, and two (2%) children had severe neurologic morbidity. The overall survival rate was 71% (84/118). CONCLUSION: BCC is an effective procedure in complicated MC twin pregnancies for selective feticide or when one fetus is severely jeopardized and delivery is not yet an option. Better outcomes can be achieved when this procedure is performed after 19 weeks.

OBJECTIVES: The aim of this study was to evaluate the efficacy of the test for the decidual phosphorylated isoform of insulin-like growth factor binding protein-1 (phIGFBP-1) in endocervical secretions in predicting preterm delivery in women with uterine contractions. METHODS: The study included 210 women with a singleton pregnancy with documented uterine contractions and intact membranes at between 24 and 34 weeks' gestation who underwent the cervicovaginal phIGFBP-1 test and transvaginal sonographic measurement of cervical length. A receiver-operating characteristics (ROC) curve was used to determine the most useful cut-off point for cervical length. A multivariate logistic regression model was used in order to analyze the combination of significant predictive variables for preterm delivery following univariate analysis. RESULTS: ROC curves indicated that 26 mm was the optimal cut-off value for cervical length in predicting preterm delivery. A cervical length of < 26 mm and the presence of phIGFBP-1 were statistically significant in univariate logistic regression analyses (P < 0.0001) with odds ratios of 16.18 and 9.29 for preterm delivery, respectively. Multivariate analysis of cervical length and phIGFBP-1 showed that they were independent and therefore useful in combination for predicting preterm delivery. CONCLUSIONS: Cervical length and the phIGFBP-1 test are independent variables that can be used together to predict preterm delivery in women with uterine contractions. A sonographically measured cervical length of > 26 mm with a negative phIGFBP-1 test in a patient with regular uterine contractions before 37 weeks' gestation seems to indicate a low risk of preterm delivery and may therefore allow avoidance of unnecessary therapies.

The purpose of the present research was to investigate the role of the fourth dimensional (4D) ultrasound scanning on the antenatal attachment development, in pregnant women (19-23 weeks of gestation) and their partners. A total of 44 couples were asked to complete questionnaires about maternal and paternal antenatal attachment, before the two-dimensional (2D; control group) and 4D (experimental group) ultrasound scanning and 2 weeks later. In the groups of women, our findings underline the progressive increase in antenatal attachment throughout gestation: the mean level of antenatal attachment was significantly different between the first and the second assessment. No significant differences are shown between 2D and 4D ultrasound scanning groups. We do not eliminate the possibility that ultrasound scanning practice would be a helpful and crucial means of investigation for a complete explanation of prenatal attachment (Ainsworth, Blehar, Waters, & Wall, 1978; Fivaz-Depeursinge & Corboz-Warney, 2000) and parental mental representations (Stern, 1987, 1997).
