Background:
Indications for angioembolization (AE) following liver injury are not clearly defined. This study evaluated the outcomes and complications of hepatic AE. We hypothesize hepatic angioembolization is a useful adjunct to non-operative management of liver injury but with significant morbidity.
Methods:
Subjects were identified utilizing trauma registries from centers in a regional trauma network from 2010 to 2017 with an Abbreviated Injury Scale (AIS) coded hepatic injury and an ICD9/10 for hepatic angiography (HA).
Results:
1319 patients with liver injuries were identified, with 30 (2.3%) patients undergoing HA: median ISS was 26, and median liver AIS was 4. Twenty-three subjects required AE. 81% had extravasation on CT from a liver injury. 63% underwent HA as initial intervention. 43% of AE subjects had liver-related complications with 35% 30-day readmission but with zero 30-day mortality.
Conclusions:
While there were zero reported deaths, a high rate of morbidity and readmission was found. This may be due to the angioembolization or the liver injury itself.
