Duplex ultrasound criteria for diagnosis of splanchnic artery stenosis or occlusion Gregory L. Moneta, MD, Richard A. Yeager, MD, Ronald Dalman, MD, Ruza Antonovic, MD, Lee D. Hall, MD, John M. Porter, MD Journal of Vascular Surgery Volume 14, Issue 4, Pages 511-520 (October 1991) DOI: 10.1016/0741-5214(91)90245-P Copyright © 1991 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

Fig. 1 Peak systolic velocities (PSV) from superior mesenteric (•) and celiac ( ̂) arteries in patients with atherosclerosis and angiographically normal splanchnic vessels (Group A) and healthy controls presumably free of significant atherosclerosis (Group B).

Fig. 2 Superior mesenteric artery (SMA) peak systolic velocities (PSV) as a function of angiographic stenosis in patients with visualization of their SMA by both angiography and duplex scanning, (r = 0.68, p = 0.0001 for angiographically patent SMAs). Note the angiographic occlusions successfully identified by duplex scanning are positioned at the extreme upper right of the figure. The horizontal line indicates the proposed PSV (275 cm/sec) for detecting a ≥70% angiographic stenosis (vertical line).

Fig. 3 Celiac artery (CA) peak systolic velocities (PSV) as a function of angiographic stenosis, (r = 0.59, p = 0.006 for angiographically patent CAs). Note the angiographic occlusion successfully identified by duplex scanning is positioned in the extreme upper right of the figure. The horizontal line indicates the proposed PSV (200 cm/sec) for detecting a ≥70% angiographic stenosis (vertical line).

Fig. 4 Straight (A) and torturous (B) paths of widely patent SMAs. Duplex determined peak systolic velocity in (A) is 88 cm/sec, whereas that in (B) is 286 cm/sec. Vessel torurosity may contribute to the recording of high peak systolic velocities in some otherwise normal superior mesenteric arteries.
