Abstract: Objective To explore the value of color doppler flow imaging（ CDFI） in diagnosis of celiac artery（ CA） stenosis. Methods The patients with abdominal pain were examined by CDFI to evalutate the initial segment of CA on observations of plaques， thrombus etc. And the peak systolic velocity（ PSV） of stenotic location was measured. 30 out- patients for healthcare were the control group， the twodementional sonograms were revealed and the PSV of CA initial segment were measured. Results 24 cases with CA stenosis were detected by sonography， including atherosclerotic plaque in 16， embolism by thrombus from rheumatic heart disease or acute myocardium infarction in 7， isolated dissection complicated with thrombus in 1. The maximum and minimum PSV at stenosis location was 420 cm/s and 228 cm/s respectively with an average of（ 304. 52 ± 53. 75） cm/s. In patients without CA stenosis， the maximum and minimum PSV at initial segment was 178 cm/s and 81 cm/s with an average of（ 113. 33±19. 70）cm/s， which were lower than those in stenotic group with statistical significance( t =16. 242， P ＜0. 000 1). Conclusion CDFI is of great value in diagnosis of CA stenosis， which can accurately display the location and degree of stenosis and the hemodynamic changes， which plays an important role in etiological screening for patients with abdominal pain.
