OBJECTIVE To assess the rate of resolution or progression after first line treatment with amnioreduction and related outcome of pregnancies with twin-to-twin transfusion syndrome (TTTS) diagnosed at stages I-II. METHOD Data on 34 monochorionic diamniotic twin pregnancies presenting with TTTS at stage I-II before 26 weeks of gestation were collected(More)
OBJECTIVE To assess ovarian response and pregnancy outcome related to midfollicular luteinizing hormone (LH) levels in normogonadotropic women down-regulated with gonadotropin-releasing hormone-agonist (GnRH-a) (daily and depot) during an assisted reproduction cycle. STUDY DESIGN In a prospective randomized trial, 50 women were down-regulated with(More)
We are reporting a case of twin reversed arterial perfusion (TRAP) sequence occurring in a dichorionic triamniotic triplet pregnancy with successful percutaneous prenatal treatment and excellent neonatal outcome. TRAP sequence was diagnosed at 11 weeks in a spontaneous dichorionic-triamniotic triplet. Sonographic assessment showed persistent arterial flow(More)
OBJECTIVE The technique used to perform transabdominal chorionic villus sampling (CVS) is not standardized, but aspiration of villi is generally obtained by discontinuous vacuum created in a syringe, manually or by a hand-grip device. We evaluated the feasibility of a new method of performing CVS which employs a 4-mL Vacutainer connected to the needle,(More)
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(More)
OBJECTIVE Residual anastomoses after fetoscopic laser surgery for twin-to-twin transfusion syndrome (TTTS) may lead to severe postoperative complications, including recurrent TTTS and twin anemia-polycythemia sequence (TAPS). A novel technique (Solomon technique) using laser coagulation of the entire vascular equator was recently investigated in a(More)
OBJECTIVE Ventriculomegaly (VM) is the most common brain anomaly in prenatal ultrasound (US) diagnosis. There is a general trend to perform fetal magnetic resonance imaging (MRI) when VM is severe (greater than 15 mm) and/or it is not isolated. The role of MRI is debated when VM is borderline (between 10 and 15 mm) and isolated. Some authors have subdivided(More)
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(More)
INTRODUCTION Vascular anastomoses in monochorionic (MC) twin placenta can be easily identified with color-dye injection. The aim of this study is to analyze the relationship between different type of anastomoses and twin pregnancy complications. METHODS From January 2011 to October 2014, MC placentas were analyzed with color-dye injection and five group(More)
OBJECTIVES To assess the value of middle cerebral artery Doppler indices obtained from different sampling sites in predicting umbilical cord gases at delivery in prolonged pregnancies. METHODS This was a prospective study of consecutive pregnant women referred for prolonged-pregnancy surveillance. The predictive value of distal and proximal middle(More)
