5 Fig 4 Box plot showing SMA PSVs pre- and post-stenting. Thick horizontal lines, boxes, and error bars denote median, interquartile range, and range, respectively, P = Dashed line represents >70% SMA stenosis for PSV >275 cm/second.

6 Fig 5 A, Pre-stent lateral aortograms demonstrating high grade SMA stenosis. B, Follow-up lateral aortograms immediately post-placement of SMA stent. The measured PSV 1 day post-stent was 360cm/second. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2009 Society for Vascular Surgery Terms and Conditions
