Abstract
The authors describe a "hypoperfusion complex", seen on abdominal computed tomography, which consists of marked, diffuse dilatation of the intestine with fluid; abnormally intense contrast enhancement of the bowel wall, mesentery, kidneys, and/or pancreas; decreased caliber of the abdominal aorta and inferior vena cava; and moderate to large peritoneal fluid collections. The complex was present in three patients less than 2 years of age and was associated with severe injury and a poor outcome. Recognition of this constellation of findings may help direct attention to the patient''s serious hemodynamic abnormality as much as to individual organ defects.
