Abstract
We performed a retrospective review of trauma patients who had undergone both pelvic angiography and preangiographic i.v. contrast-enhanced CT to determine whether CT can accurately demonstrate the presence or absence of pelvic bleeding in patients with multisystem trauma and major pelvic fractures.We reviewed the medical records and imaging studies of all patients, identified through a trauma radiology database, who had undergone pelvic angiography and preangiographic contrast-enhanced CT during a 48-month period. Results of CT scans were recorded by consensus interpretation of three radiologists without knowledge of angiographic findings. Sites of contrast material extravasation seen on CT scans were noted and compared with sites of bleeding or vascular injury identified by selective pelvic angiography.Thirty patients with blunt trauma and pelvic fractures underwent both pelvic angiography and preangiographic CT studies. Findings on pelvic angiograms were positive at 26 sites in 19 patients and included...
