Arcuate ligament syndrome mimicking celiac occlusion

In a patient with weight loss and a systolic epigastric murmur, aortography demonstrated positional celiac axis occlusion. Color Doppler imaging of the celiac axis showed occlusion in the supine position, but patency was documented during deep inspiration and with the patient in the upright position. This report documents a rare example of extreme celiac axis compression with position-dependent celiac patency.
