Abstract

Mesenteric ischemia is caused by a reduction in mesenteric blood flow. It can be divided into acute and chronic, based upon the rapidity and the degree to which the blood flow is compromised. The authors retrospectively reviewed 22 cases of mesenteric ischemia, diagnosed by multidetector computed tomography (MDCT) in our service, and confirmed by surgery or clinical follow-up. The frequency of the diagnostic findings of chronic and acute mesenteric ischemia was evaluated. The improvement of three-dimensional (3D) MDCT allows accurate assessment of mesenteric vessels. Therefore, it demonstrates changes in ischemic bowel segments helpful in determining the primary cause of the disease, and can identify the complications in patients with acute and chronic mesenteric ischemia.

Keywords

Acute mesenteric ischemia, chronic mesenteric ischemia, multi-detector computed tomography

Resumo

A isquemia mesentérica é causada pela redução do fluxo sanguíneo mesentérico. Essa patologia pode ser dividida em aguda e crônica, baseada na rapidez e no grau em que o fluxo sanguíneo está sendo comprometido. Os autores retrospectivamente revisaram 22 casos de isquemia mesentérica, diagnosticados por tomografia computadorizada com mutidetectores (TCMD) em nosso serviço, e confirmados por cirurgia ou seguimento clínico. Os achados diagnósticos de isquemia aguda e crônica e sua frequência foram avaliados. Os avanços na TCMD 3D (tridimensional) permitiram o acesso detalhado aos vasos mesentéricos. Além disso, é possível demonstrar alterações nos segmentos intestinais, auxiliando na identificação da causa primária da doença e podendo identificar as complicações associadas a isquemia mesentérica e crônica.

Palavras-chave

Isquemia mesentérica aguda, isquemia mesentérica crônica, tomografia computadorizada com multidetectores
