Bilateral internal iliac artery embolization for pelvic trauma: Effectiveness and safety.

Introduction: Bilateral internal iliac artery embolization (BIIAE) with temporary embolic materials epitomizes damage-control principles in the treatment of exsanguinating hemorrhage from pelvic trauma. However, instances of ischemic complications have been reported. The aim of our study was to assess safety and effectiveness of BIIAE.
Methods: All patients who received BIIAE for pelvic trauma at a Level I Trauma Center between 1998 and 2018 were reviewed. Effectiveness was assessed by radiographic bleeding control and clinical bleeding control, i.e. stabilization of vital signs and reduction in blood transfusion. Safety was assessed by any evidence for ischemic damage of pelvic organs or tissues.
Results: Of 61 patients undergoing BIIAE, bleeding control was confirmed radiographically in 60 (98%) and clinically in 55 (90%), including 4 (7%) patients who required repeat embolization. Six (10%) patients died due to insufficient pelvic bleeding control. No BIIAE-related complications were identified.
Conclusion: The overall clinical effectiveness and safety rates of BIIAE for pelvic bleeding control, when combined with other methods of hemostasis, were 90% and 100% respectively.
