    Abstract:
    Pelvic bone fractures in female patients are a result of high-energy trauma and are a significant cause of morbidity and mortality. Their classification is based on the mechanism of the traumatic impact force and the evaluation of stability or instability of pelvic ring fracture. Vascular hemorrhage is frequently associated with pelvic bone disruption and is the main cause of death in polytrauma female patients. At many trauma centers, multidetector computed tomography (MDCT) has been considered the best modality in the trauma setting as it is also useful in characterizing multiple-body traumatic lesions. Specifically, MDCT angiography can lead to fast recognition of pelvic vascular injuries to triage patients with blunt pelvic trauma and to send those with ongoing arterial hemorrhage to appropriate emergent treatment. At contrast medium enhanced MDCT, extravasation of contrast material is an accurate finding of active bleeding and enables the interventional radiologist to selectively investigate the arteries most likely to be involved with prompt angiographic embolization. The potential sites of hemorrhage include the pelvic bone, the pelvic venous plexus, the major iliac veins, the major iliac arteries, and their peripheral branches. MDCT multiphase protocol can accurately differentiate arterial from venous hemorrhage. This article discusses the use of multiphase contrast medium enhanced MDCT in detecting and characterizing vascular pelvic injuries associated with pelvic fractures in trauma female patients.
