Here we present a case of non-occlusive mesentery ischemia induced by digitalis, which was verified angiographically. Nonocclusive mesentery ischemia, a subgroup of "acute mesentery ischemia", is known as a period of intestinal ischemic hypoperfusion without a demonstrable vascular occlusion in the mesentery bed. It can be caused by factors leading to(More)
