Gastric ischaemia: cross-sectional imaging findings through a case series.

Gastric ischaemia is an uncommon, serious and potentially fatal disease caused by diffuse or focal gastric vascular insufficiency. It can be caused by states of systemic hypotension or disseminated vasculitis or thrombosis, even though the stomach possesses collateral circulation which, to a certain extent, prevents it from developing. Computed tomography (CT) is the technique of choice for assessing the extent of the disease, as it detects parietal hypoenhancement and gastric and/or portal pneumatosis. The treatment required depends on the aetiology and ranges from surgery to resuscitation measures. This article presents the imaging findings from a series of three cases of gastric ischaemia seen at our hospital.
