Orientation to fetal position and visceral/abdominal situs

In these views, you will appreciate the initial assessment of the fetal orientation regarding right/left - anterior/posterior. It is important to establish the position of the cardiac segments and their relationships. This includes: visceral/abdominal situs (stomach, liver position), position of the portal vein, descending aorta, and inferior vena cava relative to the axial plane of the the abdomen and the position of the cardiac apex position and axis in the chest.

Scan through the body of the fetus, placenta seen on top

Same scan but slowed-down. The cardiac axis is seen within the fetal chest towards the left of the fetal thorax.

Cross-section through the fetal abdomen indicating the descending aorta to the left of the SVC. The liver is on top. The stomach is to the left and on top of the spleen.
