title: Assessment of recurrent mesenteric ischemia after stenting with a pressure wire.
abstract: Chronic mesenteric artery ischemia can be difficult to evaluate after stent placement. This case describes the use of a pressure wire to demonstrate the hemodynamic significance of in-stent restenosis. Papaverine was used to vasodilate the mesenteric bed, mimicking the post-prandial state. The study (arteriography with pressure wire) and retreatment (covered balloon-expandable stent) was driven by recurrent symptoms avoiding unnecessary ancillary testing.
