Angioembolization is an effective adjunct to the management of retroperitoneal hemorrhage in pelvic fractures. Most patients with stable-type pelvic fracture are treated conservatively. However, in some stable pelvic fracture cases, patients should receive angioembolization for hemostasis upon incidental finding of contrast extravasation on computed tomography (CT). In this study, we attempted to define the characteristics of patients with stable pelvic fracture requiring angioembolization.We retrospectively reviewed the charts of patients with pelvic fractures between January 2005 and November 2009. We focused on stable pelvic fracture patients with contrast extravasation on CT who then received angioembolization. The demographics, Injury Severity Score (ISS), Abbreviated Injury Scale score, and the blood glucose levels on admission were analyzed.In total, 334 patients were enrolled. Patients with higher blood glucose level on admission with stable pelvic fracture had a higher rate of angioembolization. Furthermore, these patients presented with a higher Abbreviated Injury Scale score and ISS.In patients with stable pelvic fracture, higher blood glucose level on admission was associated with a higher likelihood of needing angioembolization. Blood glucose level should be checked during the initial survey of a pelvic fracture, and greater attention should be given to patients with higher blood glucose level or with an ISS of 25 or greater, even when the imaging study only reveals a stable pelvic fracture.
