Management of blunt hepatic injury in children: usefulness of emergency transcatheter arterial embolization

We reviewed our experience to determine the usefulness of emergency transcatheter arterial embolization (TAE) for severe blunt hepatic injury (BHI) in children. Between 1978 and 2000, 21 children with BHI (14 boys and 7 girls, ranging in age from 2 to 14 years) were managed according to our protocol. The patients who were hemodynamically stable, and had no other associated injury requiring laparotomy, regardless of the hepatic injury grade, were managed nonsurgically. Emergency angiography and TAE performed after a CT scan revealed extravasation of the contrast medium. Of the 21 patients, 3 underwent emergency laparotomy; 2 due to hemodynamic instability despite fluid resuscitation (I died), and the 3rd patient because of associated injury. The other 18 patients (86%) were initially managed nonsurgically; however, 2 underwent delayed laparotomy because of complications (1 each of suspected delayed hepatic hemorrhage and liver abscess). Nonsurgical management was completed in the remaining 16 (89%) with no morbidity and mortality. Two of the 16 returned to a hemodynamically stable condition with fluid resuscitation, but were compromised with persistent hepatic hemorrhage, and were successfully treated with emergency TAE. We propose that emergency TAE should be considered as an initial treatment for severe BHI in children.
