    Journal: Eur J Surg; 2000 Oct; 166(10):771-6. PubMed ID: 11071163.
    Abstract:
    OBJECTIVE: To evaluate the early and late outcome of mesenteric revascularisation in patients who had had elective mesenteric revascularisation for chronic intestinal ischaemia. DESIGN: Retrospective review. SETTING: Academic clinic, United States. SUBJECT: 19 consecutive patients (7 men, 12 women; mean age 70 years, range 53-83). RESULTS: Angiography showed that 2 mesenteric vessels were affected in 7 patients and 3 in 12. Four patients had coexisting symptomatic aortoiliac occlusive disease and 1 patient had bilateral renal artery stenosis. A total of 36 visceral arteries were revascularised. One patient died postoperatively, and 8 developed serious complications. Morbidity and mortality were significantly higher in patients who had simultaneous infrarenal aortic or renal artery reconstructions (p = 0.01). Patients whose body weight before operation was less than 90% of ideal had more complications (8/11) than patients who were within 10% of their ideal body weight (1/8) (p = 0.02). Cumulative survival was 89% at 1 year, 72% at 3 years, and 57% at 5 years. The cumulative graft patency rate was 92% at 3 years and 66% at 5 years. CONCLUSIONS: Mesenteric bypass procedures for chronic mesenteric ischaemia are durable. Long-term survival and graft patency rates are excellent even in older patients. Simultaneous aortic surgery should be avoided because of the associated morbidity. More than 10% below ideal body weight was associated with higher morbidity. For these patients, early total parenteral nutrition postoperatively, or a period of total parenteral nutrition preoperatively may reduce postoperative morbidity and mortality.
