The effect of angioembolization for life-threatening retroperitoneal hemorrhage in patients with pelvic fracture

Background: Conventionally, pelvic fracture-related acute retroperitoneal hemorrhage (ARH) is life threatening and difficult to control. However, the use of angioembolization to treat fracture-associated ARH improves the hemodynamic stability of patients with pelvic fractures. The role of angioembolization in the management of patients with pelvic fracture-related ARH was examined. Materials and methods: We retrospectively reviewed a large case series of patients with pelvic fractures between January 2010 and December 2014. Comparisons were made between patients with and without ARH. In addition, the characteristics of mortality were delineated, whereas the causes of death in patients with pelvic fracture were discussed and analyzed. Results: A total of 1070 patient records were reviewed during the 60-month study period, and the overall mortality rate of pelvic fracture was 7.7% (82/1070). However, there were only seven patients who died due to uncontrolled ARH (0.7%). The patients with ARH had more injuries to other organs than did the patients without ARH (head: 79.7% vs. 31.7%, p < 0.001; chest: 50.3% vs. 10.9%, p < 0.001; abdomen: 72.0% vs. 22.7%, p < 0.001; spine: 12.6% vs. 4.4%, p < 0.001; extremities: 69.2% vs. 44.3%, p < 0.001). Conclusion: The treatment for pelvic fracture patients declared dead upon arrival remains limited. However, pelvic fracture-related ARH could be controlled effectively with angioembolization. In addition to ARH, injuries to other organs may play a key role in the mortality of patients with pelvic fractures. (C) 2018 Elsevier Inc. All rights reserved.
