Fig 1 Studied collaterals between mesenteric arteries. CA, Celiac artery; GDA, gastroduodenal artery; HA, hepatic artery; IMA, inferior mesenteric artery; LGA, left gastric artery; PDA, pancreaticoduodenal artery; RA, renal artery; SA, splenic artery; SMA, superior mesenteric artery.

Fig 2 A, Collateral visible on selective injection only (grade 1) in a patient with stenosis of the celiac artery (CA). B, Collateral visible on nonselective visceral angiography (grade 2) in a patient with stenosis of the CA. GDA, Gastroduodenal artery; HA, hepatic artery; SA, splenic artery; SMA, superior mesenteric artery.

Fig 3 Effect of stenosis in the celiac artery (CA) on duplex velocity parameters of the CA and superior mesenteric artery (SMA) during expiration. Data are shown as mean ± standard error of the mean. PSV, Peak systolic velocity. *P < .005 comparing stenosis vs no stenosis. Journal of Vascular Surgery , e2DOI: ( /j.jvs ) Copyright © 2014 Society for Vascular Surgery Terms and Conditions

Fig 4 Patients with an angiographically normal superior mesenteric artery (SMA): effect of grade of celiac artery (CA) stenosis on SMA peak systolic velocity (PSV) during expiration. Data are shown as mean ± standard error of the mean. P = .009, analysis of variance between groups; *P < .05, post hoc Tukey test compared with normal.

Fig 5 Patients with an angiographically normal superior mesenteric artery (SMA) with and without ≥70% celiac artery (CA) stenosis: effect of existence of pathologic collateral pathways on SMA peak systolic velocity (PSV) during expiration. Data are shown as mean ± standard error of the mean. *P < .05 comparing collateral vs no collateral and stenosis vs no stenosis.

Fig 6 Patients with an angiographically normal superior mesenteric artery (SMA): effect of existence and type of collateral pathways on SMA duplex velocity parameters. Data are shown as mean ± standard error of the mean. PSV, Peak systolic velocity. *P < .05 comparing groups (analysis of variance with post hoc Tukey test) compared with no collateral.

Fig 7 Effect of stenosis in the superior mesenteric artery (SMA) on duplex velocity parameters of the celiac artery (CA) and SMA during expiration. Data are shown as mean ± standard error of the mean. PSV, Peak systolic velocity. *P < .005 comparing stenosis vs no stenosis.
