The clinical indications for arteriography in trauma to the extremity. A review of 114 cases.

Analysis of radiographic and physical findings in 114 patients with trauma to an extremity demonstrated that when other physical findings are normal, arteriography is unnecessary. If any physical sign of peripheral vascular injury exists, such as weak or absent pulse, neurologic deficit, bruit, or expanding hematoma, arteriography is essential to define the anatomy and determine the need for surgery.
