Zur Uberwachung des fetalen Zustands in utero verwendete Parameter, wie die Kurzzeitvariation (STV) der fetalen Herzfrequenz, werden durch die Gabe von Kortikosteroiden, im Rahmen der Lungenreifeinduktion bei drohender Fruhgeburt, vorubergehend beeinflusst. Diese Tatsache muss, in Bezug auf ihre Aussagekraft zur Beurteilung des fetalen Wohlbefindens im entsprechenden Zeitraum, berucksichtigt werden. Durch die Signalverarbeitungsmethode PRSA (phase-rectified signal averaging) konnte ein neuer Par...

Objectives: To evaluate the incidence of chorioamniotic membrane separation (CMS) after surgical fetoscopy in monochorionic diamniotic twins and its impact on pregnancy outcome. Methods: 338 patients with monochorionic diamniotic pregnancies complicated with twin-to-twin transfusion syndrome or selective intrauterine growth restriction that underwent surgical fetoscopy (selective laser photocoagulation of communicating vessels (SLPCV) or cord occlusion) at a single tertiary level hospital during...

Objective To compare left myocardial performance index (MPI) values and reproducibility using different settings and ultrasound equipment in order to standardize optimal machine settings. Methods Left MPI was prospectively evaluated by one observer performing conventional Doppler in 62 fetuses (28–36 weeks of gestational age) using different settings (changing sweep speed, gain and wall motion filter (WMF)) and two different ultrasound devices (Siemens Antares, Siemens; Voluson 730 Expert, GE Me...

Objectives To compare the value of Doppler surveillance with maternal blood angiogenic factors at diagnosis for the prediction of adverse outcome in late-pregnancy small-for-gestational-age (SGA) fetuses. Methods In a cohort of 198 SGA fetuses we evaluated the association of Doppler indices (mean uterine artery pulsatility index (UtA-PI) and cerebroplacental ratio (CPR)) and angiogenic factors (maternal serum levels of soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF...

The aim of this study is to evaluate the independent and combined value of gestational age, fetal weight, fetoplacental Doppler, and myocardial performance index for the prediction of individual risk of early ( 1.5 MoM (OR = 22, p = 0.015), but this event was present in only 3% of recipients. In donors, reverse end diastolic flow in the umbilical artery (OR = 14.748, p = 0.033), estimated fetal weight discordance (OR = 1.054, p = 0.036), and gestational age (OR = 0.757, p = 0.046) were independe...
