Umbilical artery catheter location: where is a UAC normally placed?

Explanation:
An umbilical artery catheter is placed by threading a catheter through one of the arteries in the umbilical cord into the fetal circulation, with the tip typically in the descending thoracic or upper abdominal aorta. This position allows reliable arterial pressure monitoring and arterial blood sampling directly from the central circulation in neonates. It’s distinct from peripheral sites such as the radial artery, femoral vein, or temporal artery, which are not used for a UAC.
