Duplex examination of the mesenteric vasculature is not a widely performed examination, but the published literature documents the ability of this test to accurately identify chronic @entity731 . The test is a recent addition to the armamentarium of noninvasive duplex technology, with studies of adequate size for statistical analysis appearing only since 1991. Two primary sets of diagnostic threshold values for significant stenoses of the superior mesenteric artery (SMA) and the celiac artery have been published and subsequently tested for accuracy. One of these recommends use of peak systolic velocity (PSV), whereas end diastolic velocity (EDV) was found to be most accurate in the other. Both sets of criteria identify overall accuracy of greater than 90% for identification of @entity6029 , and greater than 80% for diagnosis of @entity850 . Identification of @entity1593 may be aided by analysis of blood flow direction in the common hepatic artery. The finding of retrograde hepatic flow is virtually diagnostic of @entity850 or complete occlusion. Duplex also has been shown capable of identifying anatomic anomalies of the mesenteric vessel origins, a situation that occurs in approximately 20% of the population. Finally, mesenteric duplex has utility in a variety of less common @entity74 , but statistical analysis of accuracy and adequate identification of quantitative velocity thresholds have not been performed. Skilled technologists who have access to appropriate training and equipment can master this test. There is little doubt that it can replace angiography as a screening tool in the setting of suspected chronic @entity5327 .

Can duplex ultrasound replace arteriography in screening for XXXX ?
