Inflammatory polyposis two years after ischemic colon injury.
Inflammatory polyps occur in association with ulcerative colitis, Crohn's disease, and other inflammatory diseases of the colon. The occurrence of inflammatory polyps following ischemic colitis has not been well documented. A 49-year-old man suffered complications of hypoperfusion, including renal insufficiency, hepatic failure, shock lung, and ischemic colitis following emergent repair of an acute aortic dissection. Although the renal, hepatic, and pulmonary complications resolved, the patient continued to experience intermittent bloody diarrhea more than two years after his initial presentation. Barium enema and colonoscopy revealed numerous pedunculated polyps in the descending and sigmoid colon. Histopathology of the polyps removed by snare electrocautery showed them to be inflammatory polyps. We believe these are the sequelae of chronic ischemic colitis.
