Emergency Body CT > Trauma > Liver


Liver

After the spleen, the liver is the second most commonly injured organ in blunt abdominal trauma, occurring in approximately 3-10% of all patients with blunt trauma. Injury to the right hemiliver is far more common than the left lobe. Injury of the posterior segment of the right hemiliver is more common than anterior segment. Injuries to the caudate lobe are rare and usually occur in conjunction with either right or left lobe injury. The mortality rates for blunt hepatic trauma range between 8 and 25 %, most often associated with uncontrolled hemorrhage. Unstable patients are often directed straight to surgery. However, in those patients that are hemodynamically stable, CT is used to determine the extent of hepatic trauma and even those with significant injury can be managed without surgery if active bleeding is identified by CT and treated by embolization. In general, hepatic parenchymal injuries are generally lower in attenuation than normal liver.
