Direct arteriography is the criterion standard but carries risk for arterial injury from direct catheterization of the artery while also requiring specialist involvement to perform (ie, interventional radiologist or vascular surgeon). CT angiography is another reliable alternative to arteriography without the risk for direct arterial injury. It does require additional contrast beyond that used for the chest, abdomen, pelvis, or body CTs that are often also indicated in these types of trauma cases; thus, it may have added risk for nephropathy or contrast reactions over arteriography, which uses less contrast.
