Abstract
Hypovolemic shock is often seen in patients with severe blunt trauma who have suffered from blood circulation inadequate to maintain oxygen delivery to multiple organs The early recognition and prompt management of hypovolemic shock in patients with multiple injuries are mandatory to improving prognosis and patient conditions The diagnostic accuracy of computed tomography CT as a primary diagnostic tool is well established The abdominal organs show several common and classic appearances on contrastenhanced CT in patients with trauma The hypovolemic shock complex is reported in the previous literature as decreased enhancement of the viscera increased mucosal enhancement and luminal dilation of the small bowel mural thickening and fluidfilled loops of the small bowel the halo sign and flattening of the inferior vena cava reduced aortic diameter and peripancreatic edema However there have been controversial CT reports with contradictory appearances Physicians understanding these findings could prompt alternative approaches to the early assessment and management of hypovolemic shock The aim of this article is to illustrate common and wellknown abdominal CT features in patients with traumatic hypovolemic shock to discuss controversial CT signs in the pancreas and adrenal gland and to describe CT findings’ clinical implications when managing hypovolemic shock
