Abstract
The prevalence of liver injury in patients who have sustained blunt multiple trauma was reported to range from 1 to 8%. Because previous mortality rates were as high as 50–80% for severe hepatic injury, the choice of treatment was under intensive investigation. Whereas nonsurgical management was the standard treatment for the hemodynamically stable patient, there is no consensus on how to treat hemodynamically unstable patients. This report details the case of a patient who sustained blunt multiple trauma, resulting in a grade IV liver injury, graded according to the American Association for the Surgery of Trauma (AAST) Liver Injury Scale. With massive fluid and blood resuscitation, the patient was stable enough to be managed nonsurgically. With transcatheter arterial embolization (TAE), the left and right hepatic arteries were embolized with coils, which allowed for a good recovery. We hypothesize that TAE can be used in the hemodynamically unstable patient who responds to rapid fluid resuscitation and blood transfusion. We caution that there is insufficient evidence until now and would therefore not make any recommendations; however, we would question the need for surgery in unstable patients with this kind of injury in the future.
