Abstract:

Purpose. —To compare and contrast the flow patterns in celiac artery (CA) and superior mesenteric artery (SMA) in normal children to those in normal adults with the use of duplex ultrasound techniques.

Methods. —Thirty male subjects were entered prospectively to the study. Peak systolic velocities and diameter at the origin of CA and SMA were recorded while the subject was fasting for at least 4-6 hr. The Human Ethics Committee at the Faculty of Allied Health Sciences-Kuwait University approved the study. Informed consent form was obtained from all subjects.

Results. —There were 15 healthy male adults. Their average age (yr ± SD) was 22.7 ± 4.7 and their average body mass index (kg/m ² ± SD) was 23.5 ± 2.1. There were 15 healthy male children. Their average age (yr ± SD) was 7.2 ± 2.92, and their average body mass index (kg/m ² ± SD) was 18.5 ± 4.8. The average diameters (cm ± SD) of CA and SMA in adults were 0.73 ± 0.8 and 0.76 ± 0.11, and the average peak systolic velocities (cm/s ± SD) were 113 ± 17.5 and 145 ± 25.8, respectively. However, the average diameter (cm ± SD) of CA and SMA in children was 0.52 ± 0.06 and 0.53 ± 0.06, and the average peak systolic velocities (±SD, cm/s) of CA and SMA were 179.5 ± 39.5 and 175 ± 31.7. respectively. Paired student's t-test showed no statistical significance between the two groups. Coefficient of variation for diameter calculation and velocity measurement was <10%.

Conclusion. —The peak systolic velocities in normal children at the superior mesenteric artery and celiac artery are slightly greater than in normal adults but it did not exceed 200 cm/sec in CA and 275 cm/sec in SMA. The Doppler waveforms are still within normal range in both groups despite the caliber of the vessels being smaller in children. Most probably greater velocities in children are caused by the high pressure of the transducer in superficially located vessel inducing flow disturbances.
