The value of repeat cerebral arteriography in the evaluation of trauma
EJ McDonald,

In most patients with head or neck trauma, a single angiogram is sufficient to guide therapy. For those who improve slowly or not at all, however, this is not an adequate basis for diagnosis. Angiography should be repeated after an interval of time to exclude development of a surgically correctable lesion, such as pseudoaneurysm or intracerebral or extracerebral fluid collection.
