Progress in chronic mesenteric arterial ischemia.

Analysis of surgical treatment for chronic mesenteric arterial occlusive lesions in 45 patients between 1964 and 1986 has shown an evolution in diagnostic criteria, indications for operation, and surgical technique. Prior to 1976, a variety of surgical procedures (diaphragmatic crus release, arterial dilation, patch angioplasty, reimplantation, endarterectomy) were employed in treatment of patients with a wide range of symptoms and variation in number of mesenteric vessels involved. Since 1976, we have selected patients with "typical" symptoms (postprandial epigastric pain, fear of eating, weight loss) and 2 or 3 vessel disease, and have avoided surgery for celiac crus lesions. Typical symptoms were seldom present in isolated celiac artery crus compression, 4 of 15 pts (23%), but were often present with 2 or 3 vessel disease, 17 of 28 pts (61%, p = 0.03). Satisfactory resolution of pain was achieved in 18 of 24 pts with 2 or 3 vessel disease. We conclude that presence of "typical" symptoms and angiographic findings of 2 or 3 vessel disease are prerequisites for effective surgical treatment. Bypass graft is our surgical technique of choice, but the extent of arterial reconstruction required to relieve symptoms remains undefined.
