Isquemia mesentérica não oclusiva causa 20% a 30% dos episódios de isquemia mesentérica aguda. A isquemia mesentérica sem obstrução anatômica arterial ou venosa é devida a vasoespasmo mesentérico, que pode ocorrer durante períodos de fluxo mesentérico relativamente baixo, especialmente se houver doença aterosclerótica arterial subjacente. Esse estado de baixo fluxo pode resultar de insuficiência cardíaca, hipotensão ou hipovolemia.

Non-occlusive mesenteric ischaemia causes 20% to 30% of acute mesenteric ischaemia episodes. Mesenteric ischaemia without anatomic arterial or venous obstruction is due to mesenteric vasospasm, which can occur during periods of relatively low mesenteric flow, especially if there is underlying arterial atherosclerotic disease. Such low-flow state can result from heart failure, hypotension, or hypovolemia.

Non-occlusive mesenteric ischaemia causes 20% to 30% of acute mesenteric ischaemia episodes. Mesenteric ischaemia without anatomic arterial or venous obstruction is due to mesenteric vasospasm, which can occur during periods of relatively low mesenteric flow, especially if there is underlying arterial atherosclerotic disease. Such low-flow state can result from heart failure, hypotension, or hypovolemia.

    Non-occlusive mesenteric ischaemia
    Non-occlusive mesenteric ischaemia causes 20% to 30% of acute mesenteric ischaemia episodes. Mesenteric ischaemia without anatomic arterial or venous obstruction is due to mesenteric vasospasm, which can occur during periods of relatively low mesenteric flow, especially if there is underlying arterial atherosclerotic disease. Such low-flow state can result from heart failure, hypotension, or hypovolemia.
