    Abstract:
    BACKGROUND: The radiologic study of choice for evaluation of traumatic arterial injuries is conventional arteriography, but it poses the risks of an invasive procedure. Computed tomographic arteriography (CTA) is emerging as a new way to study arterial anatomy, with the additional advantages of being noninvasive and a technique that allows evaluation of different body areas simultaneously. Our experience using CTA for evaluation of traumatic arterial injuries is provided in this study. METHODS: A retrospective review over a 22-month period of all adult patients undergoing CTA for evaluation of traumatic injuries to the extremities was performed. RESULTS: A total of 97 CTA studies were performed in the 95 patients. CTA adequately demonstrated the nature and location of all the arterial injuries when compared with conventional arteriography or surgical exploration. Abnormal CTA results included 21 arterial occlusions, 2 intimal flap defects, and 2 pseudoaneurysms. Nine of these 25 injuries were confirmed by surgery only, 10 by surgery and arteriography, and 6 by arteriography only. Normal CTA results were confirmed with arteriography in 10 cases. No missed injuries were encountered in patients with normal CTA results. CONCLUSION: CTA is a reliable technique for the detection and characterization of traumatic extremity arterial injuries. These results suggest CTA may be an alternative to conventional arteriography for the diagnosis of traumatic arterial injuries.
