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.
