Abstract
Background The indication for acquiring angiographic embolization in the initial treatment of severe pelvic fractures is controversial. We describe the characteristics and outcome of 31 patients with traumatic pelvic bleeding who underwent percutaneous angiography with embolization according to a standardized protocol.
Patients and methods During an 8.5-year period, 1,260 patients were treated for pelvic trauma. We performed a prospective registration of the 46 patients who underwent angiography, and report the 31 patients who had signs of significant arterial injury on angiography, necessitating embolization.
Results The rate of significant arterial injury after pelvic trauma was 2.5%. All patients had been subjected to high-energy injuries and all were severely injured as measured by the Injury Severity Score: 41 (17–66). Pelvic arterial injury was observed with all types of pelvic trauma, including isolated acetabular (4/31) and sacral fractures (3/31). The internal iliac artery or its branches was injured in 28 of 31 patients. Survival rate after embolization was 84%, and correlated inversely with increasing patient age. None of the patients died of bleeding.
Interpretation Our findings show that significant pelvic arterial injuries occur in a minority of patients after pelvic trauma, and predominantly affect patients with multiple high-energy injuries regardless of fracture type. The effect of angiographic embolization was good.
