Chronic mesenteric ischaemia is an uncommon disease that requires treatment to relieve the symptoms of abdominal angina and to prevent intestinal infarction. Over a period of 3 years, 12 patients with visceral artery stenosis or occlusion were referred to the authors' service and 10 underwent mesenteric bypass grafting. Both the coeliac and the superior mesenteric arteries were revascularized in four patients, and the superior mesenteric artery alone in six patients, using a variety of grafts and graft configurations. This was done in conjunction with aortic graft placement in four cases and with renal bypass in three. All patients survived the procedure. At a mean follow-up of 28 months, one patient died of myocardial infarction 42 months after surgery, while all survivors are symptom-free. Chronic mesenteric ischaemia can be treated safely and effectively. The variation in the pattern of mesenteric occlusions and the frequent association with aortic and renovascular disease does not allow for a single 'best' technical solution but requires the surgical procedure to be individually tailored.
