Comparison of Doppler flow in selected maternal and fetal vessels in pregnancies with fetal intrauterine growth restriction

Abstract

Abstract Objectives: The aim of the study was to compare Doppler flows in materno-fetal circulation in pregnancies with IUGR and small for gestational age (SGA) neonatal weight or normal weight, as well as in uncomplicated pregnancies. Material and methods: The study population comprised 216 pregnant women from Lodz and Kalisz between 2003-2006. In the group I we included 68 women with IUGR observed in prenatal ultrasound examination and SGA neonates, in the group II – 29 women with IUGR observed in US but normal neonatal weight and in the group III – 110 women with normal fetal and neonatal weight. Results: Mean fetal weight in the group II was (2035g400g) and in the group I (1947g414g) and it was lower than in the group III (2765g543g) (p<0.0005). Notch in UT.A was found more often in the group I (39.7%), than in the groups III (8,4%) and II (10,3%), (p< 0,0005). The mean PI in the right UT.A in the group I (0.9570.440) was higher than in the groups II (0,718  0,259) and III (0.7300.215), (p<0.001). Abnormal Doppler flows in MCA in the groups I (39,7%) and II (34,5%) were observed more often than in the group III (6.4%), (p<0.0005). Similarly, abnormal Doppler examination in DV in the groups I (45.5%) and II (46.4%) were observed more often than in the group III (17,8%), (p< 0,0005). PI in UA in the groups I (1.0610.325) and II (0.9650.184) was higher than in the group III (0.8480,166), (p<0.0005).
