It accounts for 1 in 1000 hospitalizations but its incidence is underesti- mated because it often has a mild and transient nature. The etiology of ischemic colitis is multifactorial and the clinical presentation variable. The diagnosis is based on a combination of clinical suspicion, radiographic, endo- scopic and histological findings. Therapy and outcome depends on the severity of the disease. Most cases of the non-gangrenous form are transient and resolve spontaneously without complications. On the other hand, high morbidity and mortality and urgent operative intervention are the hallmarks of gangrenous ischemic colitis.展开更多

The diagnosis was established by colonoscopy with biopsy. There were no other obvious risk factors for intestinal ischemia. The condition resolved within 4 days. Because the use of triptans for the treatment of migraine is increasing, health care providers should be aware of their potential for inducing ischemic colitis.展开更多
