Chronic superior mesentery ischemia often presents a clinically asymptomatic diffuse atherosclerotic process. There are no compelling recommendations on the benefits of early revascularization strategy besides antithrombotic prophylaxis and statin treatment. Conversely, long-term prevalence of symptomatic cases in surgical patient cohorts is rarely reported in the literature. Acutization of chronic ischemia has a severe clinical course, so timely recognition may be considered lifesaving. We present a case of an 86-year-old woman hospitalized for acutized atherosclerotic narrowing of superior mesenteric artery. The patient was urgently operated on by aorto-mesenteric ring prosthesis revascularization. Postoperative course was uneventful and the patient regained 10 kilograms in the next few months.
