Van Dijk et al reported a score for evaluating a patient for chronic mesenteric ischemia (CMI) based on clinical and angiographic findings. The authors are from multiple institutions in The Netherlands and are members of the Dutch Mesenteric Ischemia Study Group.
Patient selection: possible chronic mesenteric ischemia (CMI)
Parameters:
(1) weight loss
(2) cardiovascular disease
(3) celiac artery stenosis in percent with or without median arcuate ligament syndrome (MALS)
(4) superior mesenteric artery stenosis in percent
