RESUMO
The purpose of this article is to review both the pathophysiology and the computed tomography features of the hypoperfusion complex and shock viscera. The main findings include dilated fluid-filled loops of bowel with hyperenhancing mucosa, intensely enhancing kidneys and mesenteric vasculature, and small caliber, dense aorta and collapsed, slit-like inferior vena cava. Variable features include increased enhancement of the adrenals, decreased enhancement of the spleen, and altered enhancement of the pancreas with both hypo- and hyperenhancement described. This complex of findings indicates a tenuous hemodynamic status and has been associated with a poor prognosis. In addition, it is important to discern this collection of findings from direct injury to the viscera to aid in appropriate triage and management of the patients' injuries.
