Haemobilia after penetrating and blunt liver injury: treatment with selective hepatic artery embolisation

Abstract

Although traumatic haemobilia is uncommon and occurs in less than 3% of liver injuries, the magnitude of the bleeding may result in life-threatening complications. This study evaluated the efficacy of selective hepatic artery embolisation (HAE) in the control of bleeding in patients with traumatic haemobilia. The demographic, clinical and angiographic data on all patients with traumatic haemobilia were obtained from a prospectively documented database of patients undergoing visceral angiography for liver haemorrhage between 1967 and 2002. During the 36-year period under review, 30 patients were found to have haemobilia on selective hepatic angiography. Ten of these 30 patients had haemobilia due to accidental non-iatrogenic trauma and form the basis of this study. In 8 of the 10 patients haemobilia resulted from penetrating liver injuries and two patients had blunt trauma. The mean delay between the initial injury and the diagnosis of haemobilia was 23.5 (range 1–120) days. The mean blood loss before angiography was 8 (range 3–19) units. Six patients were treated successfully with selective hepatic arterial embolisation, three required surgery and one resolved without any intervention. There were no deaths and no complications resulting in long term sequelae. Traumatic haemobilia is an uncommon but life-threatening complication of liver injury. Selective arterial embolisation is the initial treatment of choice with a substantial rate of success and a low incidence of serious complications.
