title: The value of plain radiographs in the prediction of outcome in pelvic fractures treated with embolisation therapy.
abstract: 40 haemodynamically unstable patients with pelvic injuries were studied to assess the ability of plain radiographs to detect haemorrhagic sites. Pelvic radiographs and bilateral angiograms were reviewed separately for detection of haemorrhagic sites in both anterior and posterior segments. Sensitivity and specificity of pelvic radiographs for the detection of haemorrhagic sites were obtained by analysis of angiographic findings. Angiography demonstrated arterial injury in 106 divisions: 26 right anterior, 22 right posterior, 33 left anterior and 25 left posterior. Sensitivities of the radiographs for predicting haemorrhagic sites were higher in the anterior segment (right, 96%; left, 100%) than in the posterior segment (right, 73%; left, 83%). However, specificities were lower in the anterior segment (right, 79%; left, 78%) than in the posterior segment (right, 100%; left, 100%). In 15 (58%) of 26 patients with in-dwelling Foley catheters, including those with catheter deviation, the severity of anterior injury indicated on plain radiographs was correlated with angiographic findings. Plain radiographs of the pelvis proved useful for predicting haemorrhagic sites in haemodynamically unstable patients with pelvic fractures, especially in those with anterior fractures.
