Fetal Superior Vena Cava Blood Flow and Its Fraction of Cardiac Output: A Longitudinal Ultrasound Study in the Second Half of Pregnancy
Stefopoulou, Maria; Johnson, Jonas; Herling, Lotta; Lindgren, Peter; Kiserud, Torvid; Acharya, Ganesh (Journal article; Peer reviewed, 2021)Introduction: In the fetus, a large proportion of the superior vena cava blood flow (QSVC) comes from the brain. To provide the possibility of using this blood flow as a representation of fetal brain circulation, we aimed ... -
Reference ranges of fetal superior vena cava blood flow velocities and pulsatility index in the second half of pregnancy: a longitudinal study
Stefopoulou, Maria; Herling, Lotta; Johnson, Jonas; Lindgren, Peter; Kiserud, Torvid; Acharya, Ganesh (Journal article; Peer reviewed, 2021)Background Fetal superior vena cava (SVC) is essentially the single vessel returning blood from the upper body to the heart. With approximately 80-85% of SVC blood flow representing cerebral venous return, its interrogation ... -
Volume blood flow-based indices of fetal brain sparing in the second half of pregnancy: A longitudinal study
Stefopoulou, Maria; Johnson, Jonas; Wilsgaard, Tom; Lindgren, Peter; Herling, Lotta; Kiserud, Torvid; Acharya, Ganesh (Journal article; Peer reviewed, 2020)Introduction Cerebroplacental ratio (CPR) and umbilicocerebral ratio (UCR) are clinically used as a measure of fetal brain sparing. These are calculated as the ratios between the pulsatility indices (PIs) of middle cerebral ...
