Hypoperfusion Complex
Etiology: trauma causing shock, is reperfusion injury to gut following hypotension and intestinal ischemia
Imaging: diffuse intestinal dilation with fluid filled loops, intense enhancement of bowel walls / mesentery / adrenals / kidneys / pancreas, decreased caliber of inferior vena cava and aorta, free fluid
Clinical: marker of hypovolemic shock, very poor prognosis – 85% die within 72 hours
Cases of Hypoperfusion Complex
Axial CT with contrast of the abdomen shows diffusely dilated intensely enhancing loops of small bowel. The aorta and inferior vena cava are very narrow in caliber. There is a hematoma in the right-sided subcutaneous tissuesAxial CT with contrast of the abdomen shows periportal edema in the liver, diffusely dilated and hyperenhancing loops of small bowel and a narrow caliber inferior vena cava.
