Abstract
Acute mesenteric ischemia (AMI) is a rare medical-surgical emergency that must be treated early due to its high morbidity and mortality. It corresponds to a sudden interruption of the blood supply to a segment of the intestine, producing ischemia, cell damage, intestinal necrosis and eventually death if it is not trea-ted. The main etiology of this condition is embolic-type arterial occlusion, followed by thrombotic, non-occlusive, and venous thrombotic. It is an infrequent pathology with a low incidence of 12 per 100,000 inhabitants in international series. During the information collection, no data was found on the Chilean population since before 1983. Its main symptom is colicky abdominal pain with a sudden onset, vomiting and diarrhea that begins after the pain. On physical examination, signs of shock and abdominal distention may be noted. Hemodynamically unstable patients should be urgently taken to exploratory laparotomy as soon as the condition is suspected, and in stable patients, an angio-CT should be requested to confirm the diagnosis and plan treatment. There are two methods to treat this pathology, open surgery and endovas-cular or minimally invasive surgery. The form of therapy depends on the preoperative or intraoperative findings and the type of etiology. Finally, with the advancement of these new methods, the mortality rate has decreased in the last decade.
