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. La isquemia mesentérica aguda (IMA) es una emergencia médico-quirúrgica poco frecuente con alta morbimortalidad. Corresponde a una interrupción brusca del aporte sanguíneo a un segmento del intestino, produciendo isquemia, daño celular, necrosis intestinal y eventualmente la muerte. La principal etiología de este cuadro es la oclusión arterial de tipo embólica, seguida por la trombótica, no oclusiva y trombótica venosa. Es una patología infrecuente con una incidencia baja, de 12 por 100.000 habitantes en series internacionales. Su principal síntoma es el dolor abdominal tipo cólico de comienzo brusco, vómitos y diarrea, esta última sucediendo posteriormente. En el examen físico se pueden constatar signos de shock y distensión abdominal. Ante la sospecha, los pacientes hemo-dinámicamente inestables deben ser llevados urgentemente a laparotomía exploradora, y en aquellos estables, se debe solicitar un Angio-TC para confirmar el diagnóstico y planificar el tratamiento. Exis-ten dos métodos para tratar esta patología: la cirugía abierta y la cirugía endovascular o mínimamente invasiva. Finalmente, con el avance de estos nuevos métodos, la tasa de mortalidad ha disminuido, significativamente, en la última década.
