Abdominopelvic computed tomography (CT) following life-saving damage control surgery (DCS) for trauma is becoming more common in the modern trauma center. Multisystem internal injuries, as well as the postoperative appearance of the peritoneal cavity, organs, bowel, and soft tissues, create a very complex and confusing picture for the interpreting radiologist. Therefore, the knowledge of DCS maneuvers and the process of damage control resuscitation (DCR) in the setting of hypothermia, acidosis, and coagulopathy are important to allow for more accurate and meaningful interpretation. Emerging literature suggests that unexpected injuries are commonly encountered on post-DCS CT; thus rapid diagnosis and communication of these are essential as they may necessitate urgent, unplanned re-intervention. In this chapter, damage control surgery will be described, with special attention to details which are important for the radiologist to know during interpretation. Expected postoperative findings on CT will be reviewed, and special emphasis will be made on frequently encountered unexpected findings on post-DCS CT.
