Chronic mesenteric ischemia is a rare disorder in the United States. Frequently, its symptoms correlate poorly with the angiographically apparent degree of mesenteric artery stenosis. Measuring the pressure gradient with a small-caliber catheter is an established means of determining whether a particular stenosis is flow-limiting, thus guiding the interventional decision when stenoses are of indeterminate angiographic significance. Using a 0.014-in guidewire, however, is potentially more accurate because it eliminates any measurement error attributable to the use of a larger, potentially obstructive catheter. We present a case of chronic mesenteric ischemia in a 70-year-old woman who had abdominal pain with multiple possible causes. We used a 0.014-in pressure wire to calculate pressure gradients and guide our decision to stent tandem lesions in the superior mesenteric artery. After revascularization, the patient's symptoms improved dramatically. To the best of our knowledge, this is the first published case in which a pressure wire was used to measure a pressure gradient in chronic mesenteric ischemia.
