“…The authors of some reports [20][21][22][23] have focused on the effect of respiration phase, especially expiration, as an essential factor affecting the fl ow velocity in the celiac artery, whereas the authors of a few other reports 24,25 in the literature put into consideration other factors affecting Doppler signal in the CA such as patient body position during the scanning. The present study was performed to study the effect not only the phase of respiration but the effect of body position in the Doppler signal in the CA during ultrasound Doppler scanning.…”

“…18 Although the diagnosis of CACS has historically been established by the use of lateral aortography, abdominal ultrasound can be a useful noninvasive tool for diagnosis of this disorder. 19 Multiple factors might affect the peak systolic velocity in the CA causing CACS, such as the phase of respiration [20][21][22] and body position during ultrasound scanning. [23][24][25] Phase of respiration is a well-established factor that affects the CA during ultrasound scanning.…”

Introduction.-Multiple factors might affect the velocity recording in the celiac artery (CA), causing a compression syndrome. Reports that focused on the phase of respiration found that the CA is highly compressed during the phase of expiration. Few reports in the literature have focused on body position during Doppler scanning of the CA. The aim of this study was to evaluate the effect of patient position as well as the phase of respiration on velocity recording in the CA.Methods.-Thirty male subjects were entered prospectively into the study. Peak systolic velocity and vessel diameter at the origin of the CA at different body position and different phases of respiration were recorded by the use of duplex ultrasound while the subject was fasting.Results.-There were 30 healthy men; their average age was 25.5 ± 5.30 (±SD, years), and their average body mass index was 24.8 ± 3.1 (±SD, kg/m 2 ). The average diameter of CA in supine position and expiration was 0.70 ± 0.10 (±SD, cm), and the average peak systolic velocity was 111.2 ± 29.7 (±SD, cm/s). Moreover, the average diameter of CA in standing position in expiration was 0.75 ± 0.10 (±SD, cm), and the average peak systolic velocity was 96.8 ± 25.2 (±SD, cm/s). Paired Student t test for the effect of body position and phase of respiration in the peak systolic velocities and the diameter of the CA was performed and demonstrated statistical signifi cance (p < 0.05).Conclusion.-The CA peak systolic velocity varies between 2 positions in healthy young men, which may have implications for disease detection and needs further study.

“…It reveals variation of peak systolic velocity (PSV) during respiration with a marked increase during expiration to more than 200cm/s. A greater than 3:1 ratio of PSV in celiac axis in expiration compared with PSV in abdominal aorta immediately below diaphragm can be used as other criterion (18,19,20) . Reversal of flow in hepatic artery may also be seen (6) .…”

“…1 With median arcuate ligament syndrome, the abnormal Doppler findings as described are seen with expiration, but findings are normal with inspiration. 2 Our experience suggests that the celiac artery should be interrogated not only with full inspiration and expiration but also with the patient in the erect position. In our 2 cases, improved flow was shown in the artery only with the patient in the erect position, whereas no improvement was noted with inspiration.…”

Objective. To describe the importance of obtaining erect views when evaluating the celiac artery with sonography. Methods. Two patients had duplex and color flow Doppler sonographic evaluations of the celiac artery, including inspiration, expiration, and erect views. Results. Both patients had elevated celiac artery velocities with inspiration and expiration. These results alone would suggest celiac artery stenosis. With erect views, the celiac artery velocities returned to normal. The addition of erect views allowed the correct diagnosis of median arcuate ligament syndrome to be made. Conclusions. When evaluating the celiac artery, it is important to include erect views to prevent misdiagnosis of celiac artery stenosis. uplex and color flow Doppler sonography have been used to identify patients who have celiac artery stenosis as well as patients with median arcuate ligament syndrome. In celiac artery stenosis, peak systolic velocities are elevated with both inspiration and expiration. In contrast to this is median arcuate ligament syndrome, in which the peak systolic velocities are elevated with expiration and return to normal with inspiration. To our knowledge, there have been no previous reports of celiac artery peak systolic velocities that remained elevated with inspiration and expiration yet returned to normal levels when the patient is placed in the erect position. We present 2 cases in which the celiac artery peak systolic velocities were elevated with both inspiration and expiration but returned to normal with the patients in the erect position. Case DescriptionsCase 1 A 28-year-old woman was referred for abdominal sonography, including mesenteric Doppler imaging, for evaluation of abdominal pain. Real-time color Doppler evaluation of the aorta and its major branches was performed by an anterior approach in both the supine and
