MEASUREMENT OF NORMAL INDICES OF CELIAC ARTERY DOPPLER ULTRASOUND IN PERSONS OVER 20 YEARS OLD

Doppler ultrasound is one of the non-invasive methods for blood flow assessment in cardio-vascular system and celiac trunk as the first branch of abdominal aorta is an important splanchnic artery. According to the relative differences in the reports of normal indices from doppler ultrasound of the celiac artery in the different medical centers of the world, it was decided to evaluate this issue in the department of sonography of Hazrat-e-Rasool-e-Akram Hospital in Tehran. 84 normal persons (42 men and 42 women over 20 years old) were selected by quata convenience non probability sampling method with no exclusive criteria and with the use of doppler ultrasound scanner (HITACHI: EUB-525). Different variables such as PSV(Peak Systolic Velocity), EDV(End Diastolic Velocity), MV(Mean Velocity), d(celiac trunk diameter), RI(Resistance Index), PI(Pulsatility Index), VF(Volume Flow) and doppler spectral wave forms were studied. This study was performed in the fasting and resting(supine) state. Exclusive criteria have been indicated in subject of methodology. This research had the following general 1- Mean and standard deviation(SD) of PSV of celiac artery were 96 cm/s and 20.354 cm/s respectively. 2- Mean and SD of EDV of celiac artery were 31 cm/s and 2.967 cm/s respectively. 3- Mean and SD of MV of celiac artery were 65 cm/s and 11.566 cm/s respectively. 4- Mean and SD of diameter of celiac artery were 0.54 cm/s and 0.0767 cm/s respectively. 5- Mean and SD of RI of celiac artery were 0.66 cm/s and 0.0508 cm/s respectively. 6- Mean and SD of PI of celiac artery were 0.98 cm/s and 0.1189 cm/s respectively. 7- Mean and SD of VF of celiac artery were 877 ml/min and 145.745 ml/min respectively. 8- Doppler spectral wave forms had low-pulsatility pattern with forward continuous flow in diastole. 9- Between different age groups, there was a significant difference in PSV, EDV, MV, d, RI, PI and VF (P< 0.05), so PSV, EDV, MV, RI and PI increased with aging, while d and VF decreaed with aging. 10- Finally, there was not any significant difference between men and women in indicated variables.
