Background:

the acute mesenteric ischemia is a highly lethal disease, mainly due to the rapid evolution from its premature stage to the late one, the symptomatology in its start-up period and for the complexity of its management.

Objective:

to determine the clinical, laboratory, imagenological and evolutionary differences between the stages of the disease.

Methods:

an analytical transversal study was carried out. The universe was composed by 32 patients with acute mesenteric ischemia positive diagnosis in the period from December 2015 to March 2018, in Vladimir Ilich Lenin General Hospital.

Results:

peritoneal reaction is linked to the advanced stage in a highly significant way. There were no air-fluid levels in most of the ischemic patients, unlike the nechrosis stage, where levels were present in most of the patients. The difference between the pH and lactate average values in both of disease phases were statistically highly significant. All the cases with atrial fibrillation were dianosed in the late stage. All the patients with intestinal necrosis and more than 2/3 of the affected with intestinal ischemia perished.

Conclusions:

the delay in diagnosis was associated with high mortality. The early clinical suspicion of an acute abdomen, the assessment of hemodynamic parameters and the identification of risk factors such as atrial fibrillation, favor timely treatment in the ischemic stage and the possibility of survival.
