  • Title: Marked increase in flow velocities during deep expiration: A duplex Doppler sign of celiac artery compression syndrome.
    Author: Erden A, Yurdakul M, Cumhur T.
    Journal: Cardiovasc Intervent Radiol; 1999; 22(4):331-2. PubMed ID: 10415466.
    Abstract:
    Symptoms of chronic mesenteric ischemia develop when the celiac artery is constricted by the median arcuate ligament of the diaphragm. Lateral aortography is the primary modality for diagnosing ligamentous compression of the celiac artery. However, duplex Doppler sonography performed during deep expiration can cause a marked increase in flow velocities at the compressed region of the celiac artery and suggest the diagnosis of celiac arterial constriction due to the diaphragmatic ligament.
