ABSTRACT
Inadequate perfusion of the colon results in varying degrees of ischemic injury and
systemic manifestations. Ischemic colitis is the most prevalent form of gastrointestinal
ischemia. The overwhelming majority of cases are idiopathic in origin, respond to
conservative medical management, and proceed with a benign course. Although long-term
sequelae are uncommon, persistent colitis and ischemic strictures are identified complications.
The minority of cases that progress to full-thickness necrosis demand urgent surgical
resection and are associated with a mortality rate reaching 60%. Following aortic
surgery, ischemic colitis can be a particularly challenging complication. Early recognition
and rapid initiation of appropriate supportive treatment are critical to avoiding
further bowel compromise.
