Improving the Screening Criteria for blunt cerebrovascula injury: the appropriate role for computed tomography angiography. Emmett KP, Fabian TC, DiCoco JM, Zarzaur BL, Croce MA. J Trauma 2011: 70: 1058-65. These authors reported a large series of patients who sustained blunt trauma and were treated at the Elvis Presley Trauma Center, and determined that 0.58% of the patients had a blunt cerebrovascular injury. These investigators routinely perform an invasive angiogram, a digital subtraction angiogram, to evaluate the two carotids and two vertebral vessels in patients considered high risk due to mechanism or physical findings. The authors performed 748 digital subtraction angiograms and observed that one half of the injured carotid or vertebral arteries did not have a positive finding on a CT angiogram that was obtained at the same time.
