    Abstract:
    The condition of patients sustaining penetrating neck trauma often appears deceptively stable, even when major structures have been injured. The clinician must identify patients who require treatment and limit invasive procedures in those without significant injuries. Angiography is often used to search for vascular damage following penetration of the neck and face. The charts of 401 hemodynamically stable patients with penetrating cervicofacial wounds who were evaluated by angiography followed, when necessary by either transcatheter arterial embolization and observation or surgery were reviewed. One hundred twelve patients (27.9%) had 131 vascular injuries identified by angiography; 77 (68.8%) of these patients sustained injuries to zone III of the neck or the face. The most commonly injured vessels were the internal carotid artery (ICA), the vertebral artery, and the external carotid artery (ECA) system. Multiple vessel injuries were seen in 17 (15.2%) of 112 patients and were more likely in patients with wounds in zone III or above than in those wounded in zone II or below (20.8% vs. 2.9%, respectively; P < .025). Injuries to the internal maxillary artery (IMA) (60%), ECA (53.3%), and the ICA (30.8%) were also significantly more likely to be accompanied by additional vascular injuries (P < .005). No clinically significant venous injuries were missed. Complications were noted in only 4 patients, and no deaths occurred as a result of angiography. Angiography is a safe, effective modality in the head and neck trauma setting. Particular scrutiny should be given to patients with zone III or facial wounds, particularly those with documented ICA, IMA, and ECA injuries, since these patients have a higher incidence of multiple vascular injuries.
