[Pelvic and perineal trauma. Diagnosis and interventional radiotherapy].

The integration of multislice CT (MSCT) in the imaging of emergency trauma has led to a paradigm shift in trauma management. In case of hemodynamically instable patients, initial imaging is limited to a small set of standardized radiographs. Computed tomography is the imaging modality of choice for further diagnostic work-up. Consequently it should be used at an early stage and in a less restricted manner for complete assessment of the pelvic injury and to determine therapeutic management. The MSCT allows full assessment of bone, parenchymal, and vascular injuries in a single examination in the shortest time possible. High-resolution 3D imaging provides additional options. There is increasing support for primary use of MSCT in critically ill patients due to the comprehensive imaging it allows while maintaining a fast scan time. The potential and limitations of diagnostic imaging in pelvic ring fracture and associated injuries are explained. Indications for vascular interventions in arterial bleeding are discussed.
