OBJECTIVE To describe perinatal outcomes achieved with cord occlusion (CO) in monochorionic twins with severe selective intrauterine growth restriction (sIUGR) and abnormal umbilical artery Doppler in the IUGR twin (types II and III). METHODS We studied a consecutive series of 90 cases of sIUGR with abnormal Doppler treated with CO of the IUGR fetus. Abnormal Doppler was defined as continuous...

OBJECTIVE To identify the sequence of progression of arterial and venous Doppler abnormalities from the onset of placental insufficiency in intrauterine growth restriction (IUGR). METHODS Prospective observational study of singletons with IUGR (abdominal circumference < 5(th) percentile) who underwent serial standardized umbilical artery (UA), middle cerebral artery (MCA), ductus venosus (DV)...

OBJECTIVE We hypothesized that maternal and fetal circulations may be affected by moderately high altitudes. Therefore, we compared the differences in maternal and fetal Doppler flow parameters in women with term pregnancy living at a moderately high altitude (1890 m in Erzurum) with those of women living at the sea level (31 m in İstanbul). MATERIAL AND METHODS Eighty women (n=40, for each g...

34 35 The present study was conducted to determine the impact of suppressing trophoblast 36 remodeling of the uterine spiral arteries by prematurely elevating estrogen levels in the first 37 trimester of baboon pregnancy on uterine and umbilical blood flow dynamics. Uteroplacental 38 blood flow was assessed by Doppler ultrasonography after acute administration of saline (basal 39 state) and ser...

conclusions in the absence of associated anomalies, the risk of incidence of adverse events does not appear to be increased significantly with isolated sua. therefore, supplementary assessment and invasive tests are not recommended in fetuses with isolated sua, unless fetal abnormalities are detected in routine evaluations. background the umbilical cord normally consists of two arteries and one...

Introduction Preeclampsia is the first cause of maternal morbidity and mortality, intrauterine growth retardation (IUGR), and fetal prematurity (Abdel Razik, 2016). Preeclampsia affects 5-10% of pregnancies and is clinically manifested after 20 weeks of gestation. Fetal hypoxemia caused by preeclampsia can lead to ischemic encephalopathy, growth retardation, and various sequalae of premature bi...
