Pelvic ring fractures with concomitant large hematomas: diagnostic investigation with arteriography and eventual embolization in 157 trauma patients, with or without contrast extravasation at emergency CT.

In this study, patients with pelvic ring fractures and concomitant hematomas > 3 cm, with or without contrast extravasation at CT, have been examined in depth with DSA focusing on both direct and indirect angiographic signs of bleeding, finding polytrauma and Tile fracture patterns B3/C1 predictive factors for arterial hemorrhage detection at DSA despite negative CT findings.
