Correlation between the Fetal Liver Length and Crown- Rump Length During the First Trimester Screening
Objective: The aim of the present study was to determine the correlation between fetal liver length (FLL) at the 11+0–13+6 week of pregnancy and crown-rump length (CRL). Methods: Pregnant women (n=63) referring to the Başkent University Konya Hospital Obstetrics and Gynecology Clinic between January and March 2014 for first trimester screening were included in the study. Patients were excluded ...
متن کاملStandardisation of crown-rump length measurement.
Correct estimation of gestational age is essential for any study of ultrasound biometry and for everyday clinical practice. However, inconsistency in pregnancy dating may occur through differences in measurement methods or errors during measurement. In the INTERGROWTH-21(st) Project, pregnancies are dated by the last menstrual period, provided that it is certain and associated with a regular me...
متن کاملFetal heart assessment in the first trimester of pregnancy: influence of crown-rump length and maternal body mass index
OBJECTIVE To evaluate the influence of the crown-rump length and body mass index on sonographic evaluation of the fetal heart using abdominal and vaginal routes in the first trimester of pregnancy. METHODS We conducted a cross-sectional study with 57 pregnant women between 12-14 weeks (CRL< 84 mm). We evaluated the following fetal cardiac plans using the abdominal and vaginal routes: four-cha...
متن کاملIntertwin estimated fetal weight or crown rump length discordance and adverse perinatal outcome.
AIM In the current review study, we present recent data regarding the importance of intertwin estimated fetal weight (EFW) and crown rump length (CRL) discordance for the prediction of adverse perinatal outcome both in monochorionic and in dichorionic diamniotic gestations. RESULTS Twins with significant weight disparity are associated with higher rates of perinatal morbidity and mortality, r...
متن کاملIntrauterine position affects fetal weight and crown-rump length throughout gestation.
To investigate the effect of intrauterine positions on fetal growth throughout gestation, data from a total of 65 gilts (n = 784 fetuses) that were slaughtered at assigned days of gestation (d 43, 58, 73, 91, 101, and 108) on a project to evaluate fetal mineral deposition were used. Placenta units were removed from the uterus, and position, sex, weight, and crown-rump length (CRL) of each fetus...
