The aim was to describe the course of physiological changes in coeliac artery (CA) and superior mesenteric artery (SMA) blood flow velocities (BFVs) during the perinatal period in healthy term fetuses and infants as it has not been studied in detail so far.
This prospective Doppler ultrasound study included 50 infants. The examinations were performed in a fetus after the completion of 36.0 gestation weeks before the onset of labor and in infants postnatally at the ages of 2, 24, and 72 h.
The end-diastolic velocity (EDV) in the CA was generally higher than in the SMA (p < 0.001). The EDV in the SMA decreased postnatally (8.4 vs. -7.2, p < 0.001) and showed negative values in 92% of infants. By 24 h of postnatal age, EDV in the SMA had become positive in all of the infants (mean 13.8 cm/s, p < 0.001). The EDV in CA had only positive values. The changes in EDV in both vessels were reflected by changes in the resistance index in inverse manner.
BFV in the CA and SMA changed dramatically in the perinatal period; the most remarkable changes occurred within the first 24 h of life.
本研究旨在描述健康足月儿和婴儿围生期腹腔干（CA）和肠系膜上动脉（SMA）血流速度（BFV）的生理变化过程，因为目前尚未对此进行详细研究。
这项前瞻性多普勒超声研究纳入了50名婴儿。在妊娠36.0周后、临产前对胎儿进行检查，并在出生后2、24和72小时对婴儿进行检查。
CA的舒张末期速度（EDV）通常高于SMA（p < 0.001）。SMA的EDV在出生后下降（8.4对-7.2，p < 0.001），92%的婴儿出现负值。到出生后24小时，所有婴儿SMA的EDV均变为正值（平均13.8 cm/s，p < 0.001）。CA的EDV仅为正值。两条血管中EDV的变化以相反的方式反映在阻力指数的变化中。
CA和SMA的BFV在围生期发生了显著变化；最显著的变化发生在出生后的头24小时内。
