Chronic mesenteric insufficiency presents clinically in a subtle fashion, yet has a devastating effect on the patient over time and may require surgical intervention. Duplex Doppler can be used to detect chronic mesenteric insufficiency and to follow up on surgical revascularization. Key parameters in diagnosing mesenteric insufficiency are reported to be decreased peak systolic and end-diastolic velocities from preto postprandial. More information about normal and abnormal velocity ranges is still needed. A literature review of the noninvasive diagnostic role for duplex sonography in mesenteric circulation and a description of current preand postprandial scanning techniques are discussed.
