title: Surgical revascularization in chronic mesenteric ischemia.
abstract: Chronic mesenteric ischemia (CMI) is a disease causing death either by starvation or enteromesenteric infarction. Diagnosis is often delayed before the patient is referred to a vascular surgery unit. Atherosclerosis is the main cause of CMI. Arteriography is essential in diagnosing CMI and delineating the atherosclerotic lesions. The revascularization procedure consists in an aortomesenteric bypass reconstructing 1-3 visceral arteries. This paper presents two consecutive CMI cases treated at the Vascular Surgery Unit of the Iaşi "Sf Spiridon" Hospital during 2010. Both patients had symptoms suggestive of mesenteric and aortoiliac diseases. CT angiography revealed specific lesions both for aortoiliac disease and stenotic or occlusive lesions in the celiac trunk and mesenteric arteries. Both cases benefited from aortobifemural bypass surgery using a synthetic graft associated with aortic-superior mesenteric artery bypass with reversed vein graft (in the first case both mesenteric arteries were revascularized). Immediate and remote results were favorable, with remission of intestinal symptoms and weight gain. Bypass patency was followed-up by CT angiography and Doppler ultrasound. CMI is a diagnostic and therapeutic challenge. Open surgery provides symptom remission in 90% of cases. Permeability at 5 years is 80-90% for open surgery, higher than by endovascular therapy. Average permeability of the two types of intervention is 70% at 5 years, similar to the infraaortic bypasses.
