Fetal growth restriction is associated with prioritization of umbilical blood flow to left hepatic lobe, at the expense of the right lobe (2009)

Kessler, Jorg, Rasmussen, Svein, Godfrey, Keith, Hanson, Mark, Kiserud, Torvid

Eighty to 85% of the venous perfusion to the fetal liver is from the umbilical vein, the rest from the portal vein. Umbilical venous flow to the liver is essential for intrauterine growth, and is...

Fetal superior mesenteric artery: longitudinal reference ranges and evidence of regulatory link to portal liver circulation (2009)

Ebbing, Cathrine, Rasmussen, Svein, Godfrey, Keith M., Hanson, Mark A., Kiserud, Torvid

Objective: To establish longitudinal reference ranges for the fetal superior mesenteric artery (SMA) flow velocity and pulsatility index (PISMA). Also to examine the hemodynamic relationship to...

Fetal age assessment based on 2ndtrimester ultrasound in Africa and the effect of ethnicity (2008)

Salpou, Daniel, Kiserud, Torvid, Rasmussen, Svein, Johnsen, Synnøve

Abstract Background The African population is composed of a variety of ethnic groups, which differ considerably from each other. Some studies suggest that ethnic variation may influence dating. The...

Fetal size in the second trimester is associated with the duration of pregnancy, small fetuses having longer pregnancies (2008)

Johnsen, Synnøve L, Wilsgaard, Tom, Rasmussen, Svein, Hanson, Mark A, Godfrey, Keith M, Kiserud, Torvid

Abstract Background Conventionally, the pregnancy duration is accepted to be 280–282 days. Fetuses determined by ultrasound biometry to be small in early pregnancy, have an increased risk of...

Longitudinal study of umbilical and portal venous blood flow to the fetal liver: low pregnancy weight gain is associated with preferential supply to the fetal left liver lobe (2008)

Kessler, Jorg, Rasmussen, Svein, Godfrey, Keith, Hanson, Mark, Kiserud, Torvid

Recent data suggest that umbilical venous perfusion of the fetal liver has an important influence on fetal growth and postnatal liver function, and that maternal factors in late pregnancy modify this...

Fetal liver-sparing cardiovascular adaptations linked to mother's slimness and diet (2005)

Haugen, Guttorm, Hanson, Mark, Kiserud, Torvid, Crozier, Sarah, Inskip, Hazel, Godfrey, Keith M.

Fetal adaptations to impaired maternoplacental nutrient supply include altered regional blood flow. Whether such responses operate within the normal range of maternal body composition or diet is...

Circulatory responses to maternal hyperoxaemia and hypoxaemia assessed non-invasively in fetal sheep at 0.3-0.5 gestation in acute experiments (2001)

Kiserud, Torvid, Jauniaux, Eric, West, Daniel, Ozturk, Ozkan, Hanson, Mark A.

Objectives: to determine fetal haemodynamic responses to hyperoxaemia and hypoxaemia in early pregnancy. Design: repeated measurements in acute experiments. Setting: experimental physiology...
