Use of the initial @entity130 CT scan to aid in diagnosis of XXXX .

Open pelvic disruptions represent high-energy injuries. The prompt identification and management of these injuries decreases their associated morbidity and mortality. Computed tomography (CT) scans are routinely obtained in the initial evaluation of @entity1 with @entity130 . The purpose of this study is to identify the incidence and source of air densities noted on computed tomography (CT) scans of the abdominal and pelvic region in @entity1 with @entity174 and evaluate the use of initial CT imaging as an adjunctive diagnostic tool to identify open injuries. A retrospective review of a prospectively collected database was performed at a single institution. Seven hundred and twenty-two consecutive @entity1 with a pelvic disruption over a two-year period were included. Review of @entity130 scans was performed using bone and lung viewing algorithms to identify the presence of extra-luminal air. The primary outcome was the presence, location and source of air identified on pre-operative CT scans. Secondary measurements were identification of air by plain radiograph and correlation between identified air densities on CT and clinically diagnosed @entity4422 . Ninety-eight @entity1 were identified as having extra-luminal air densities on CT scans. Eighty-one @entity1 were included in the final analysis following application of inclusion and exclusion criteria. Air was noted by the radiologist in forty-five (55.6%) instances. Six @entity1 (7.4%) were clinically diagnosed with an open pelvic ring disruption; in two @entity1 (2.4%) this diagnosis was delayed. In all @entity1 , the CT was able to track air from its origin. In @entity1 with pelvic disruptions, the @entity130 should also be evaluated for the presence and source of extra-luminal air. In some @entity1 , this finding may represent an open pelvic ring disruption. A complete physical exam and CT evaluation should be used to decrease the missed or delayed diagnosis of an open @entity130 .
