Abstract
The purpose of this study is to describe CT findings of shock bowel (diffuse abnormality of the small bowel observed in hypotensive or hypoperfused patients after blunt abdominal trauma) and to determine the clinical significance of CT-diagnosed shock bowel.A data base search of a radiology data registry indicated 13 patients had CT scans obtained at admission that showed diffuse abnormalities of the small bowel and a corresponding medical history of profound clinical shock preceding CT study. All patients sustained blunt abdominal trauma: nine were involved in motor vehicle collisions, three were struck by motor vehicles, and one had a crushing injury. Vehicular impacts were typically high speed, inducing multisystem injury. Admission and follow-up CT studies were reviewed to characterize and assess the evolution of the abdominal CT findings that occur with shock bowel. Medical records were reviewed to determine blood pressure at the accident scene or on admission, surgical findings, and patient outcome....
