Colonic ischemia is the most common form of intestinal ischemia. It results from reduction in blood flow to the gastrointestinal tract, which, when prolonged, brings a spectrum of gross and microscopic changes in the affected intestinal wall. Clinical presentations range from asymptomatic to acute and fulminant, and outcomes from reversible to chronic and progressive or fulminant, with high morbidity and low mortality. This article presents an overview of colonic ischemia and discusses potential changes in imaging and treatment.
