Acute mesenteric ischemia (AMI) continues to be associated with a high mortality rate over the last decades. The purpose of the present report is to assess a cohort of 14 patients with AMI undergoing emergent surgery due to either superior mesenteric artery (SMA) embolism or thrombosis. This study is an observational and retrospective analysis during a 5-year period (2007-12). The main objective was to analyze clinical and demographic characteristics, diagnostic and therapeutic approaches and factors that affected the AMI mortality rate. 14 patients, 8 were women (57%) and 6 were men (43%) with a mean age of 75 years. SMA embolism was the cause o AMI in 70% of cases. Cardiac arrhythmias and hypertension were the most common co-morbidities. Most cases were diagnosed after 24 hours of clinical evolution and abdominal pain was the predominant symptom. Leukocytosis, elevated blood level of lactate dehydrogenase and positive d-dimers were also the most common biochemical markers. Ten patients were submitted to embolectomy and four to SMA bypass. 50% underwent intestinal resection and a second look was carried out in 14%. 30-day mortality was 57% (60% in embolism and 50% in thrombosis). Advanced age, multiple co-morbidities and prolonged ischemia were contributing factors to this high mortality.
