Limited role of arteriography in penetrating neck trauma.

Of the patients with penetrating neck wounds treated between 1979 and 1986, 61 patients with 65 injuries had arteriography during their evaluation. Twenty-seven patients had stab wounds and 34 had gunshot wounds, with a relatively equal distribution between the zones of injury. Fifty-seven arteriograms were normal and six were abnormal. Of the six arteriographic defects, three were thought to be spurious on subsequent review, two were clinically insignificant, and one required surgery. No significant arterial injuries were identified by arteriography in the absence of suggestive physical findings. No major arterial injuries were discovered during neck surgery that were missed preoperatively. Neither abnormal nor normal angiograms significantly altered the course of management, including the approach to neck exploration. These data suggest that arteriography for penetrating neck trauma is usually unnecessary for observation of patients in stable condition without suggestive physical findings. Thorough neck exploration with dissection of the carotid sheath in patients with physical diagnostic criteria for surgery eliminates the need for angiography in most cases and avoids the consequences of a possible false-negative study.
