Abdominal compartment syndrome in children: CT findings

Abdominal compartment syndrome (ACS) is caused by pathological elevation of intra-abdominal pressure (IAP) leading to multiple organ dysfunction syndrome. Since the condition is highly lethal, early diagnosis is imperative. We evaluated the pre-operative abdominal CT scans of three children with proven ACS to identify signs of elevated IAP. Findings common to these patients included narrowing of the inferior vena cava (IVC), direct renal compression or displacement, bowel wall thickening with enhancement and a rounded appearance of the abdomen. The aim of recognising the CT findings in such cases is to plan emergency surgical decompression. Although these findings are not specific for increased IAP, radiologists should be aware of this life-threatening condition and, in the proper clinical setting, should communicate the presence and significance of these findings to the referring clinician.
