Placental changes in idiopathic intrauterine growth restriction
Abstract Introduction Placenta is the maternal–foetal contact zone. The placentas of ‘idiopathic’ intrauterine growth retardation babies may hold the key to the aetiology of growth restriction. It was noted by most workers that in cases of intrauterine growth retardation placentas, there were some abnormal positions of insertion of umbilical cords, placental weight and volume was significantly ...
متن کاملProgression of Doppler abnormalities in intrauterine growth restriction.
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)...
متن کاملFetoplacental biometry and umbilical artery Doppler velocimetry in the overnourished adolescent model of fetal growth restriction.
OBJECTIVE The purpose of this study was to evaluate ultrasonographically fetal growth trajectories, placental biometry, and umbilical artery (UA) Doppler indices in growth-restricted pregnancies of overnourished adolescent ewes and normally developing pregnancies of control-fed ewes. STUDY DESIGN Singleton pregnancies were established using embryo transfer in 42 adolescent ewes that were over...
متن کاملDoppler deterioration in intrauterine growth restriction: Unterscheider et al.
The article below summarizes a roundtable discussion of a study published in this issue of the Journal in light of its methodology, relevance to practice, and implications for future research. Article discussed: Unterscheider J, Daly S, Geary MP, et al. Predictable progressive Doppler deterioration in IUGR-does it really exist? Am J Obstet Gynecol 2013;209:539.e1-7.
متن کاملHow useful is uterine artery Doppler ultrasonography in predicting pre-eclampsia and intrauterine growth restriction?
All editorial matter in CMAJ represents the opinions of the authors and not necessarily those of the Canadian Medical Association. Pre-eclampsia and intrauterine growth restriction remain important causes of maternal and neonatal complications and death. These 2 conditions are felt to be the result of abnormal placenta formation involving abnormal trophoblast invasion of spiral arteries and a r...
