Computed tomography detection of active mesenteric hemorrhage following blunt abdominal trauma.

Following blunt abdominal trauma, patients still may be actively bleed ing, despite seeming hemodynamically stable. By detecting extravasation of contrast-enhanced blood in the absence of any other evidence to support solid visceral injury as the source, computed tomography (CT) scanning was able to indicate ongoing hemorrhage in two patients, thought most likely of mesenteric origin. This information influenced the decision for intervention, which in these two cases was laparotomy, where bleeding torn mesenteric vessels were confirmed.
