Chronic mesenteric arterial insufficiency: results of revascularization in 33 cases.

The symptoms of mesenteric arterial insufficiency and the advantages of surgical revascularization have become widely recognized in recent years. Follow-up data are accumulating on patients who have had surgery for revascularization. In this study we report on 33 patients who had mesenteric revascularization for intestinal angina. Twenty-nine patients presented with postprandial pain; most had weight loss. Abdominal bruits were heard preoperatively in 26 patients. Aortogram demonstrated involvement of one mesenteric vessel in 13 (39%) patients and two or more vessels in 20 (61%). Revascularization was accomplished with the use of a Dacron graft or an autogenous vein bypass graft to 48 vessels. Endarterectomy and patch angioplasty were done once. One patient died in the early postoperative period. Of the other 32 patients, 30 (94%) had relief of symptoms. Eight patients died from 8 to 135 months after operation, but only one died from mesenteric vascular occlusion and bowel infarction. Five years after operation, 83% of the patients were alive; in ten years, 62%.

Vascular grafts in the elderly.

The incidence of symptomatic atherosclerotic occlusive disease is increasing as the life expectancy of our population rises. Most prosthetic vascular grafts are made of Dacron, which can be knitted or woven, depending on degree of porosity desired. Atherosclerotic occlusive disease can be classified by location: Group I, disease in the coronary arteries, usually treated by arterial bypass surgery; Group II, disease in the brachiocephalic vessels, usually treated by carotid endarterectomy; Group III, disease in the branches of the abdominal aorta, usually treated by a bypass from the aorta to the affected artery; and Group IV, disease in the terminal abdominal aorta and its branches, usually requiring aortofemoral bypass graft. Another type, aneurysm, usually requires resection and graft replacement. Despite advancing age, patients with atherosclerosis, when properly selected, can benefit from reconstructive vascular surgery without excessive risk.
