RESUMEN
RATIONALE: Penetrating neck traumas are dangerous and have a high mortality rate, particularly in patients with common carotid artery injuries. Advances in diagnostic imaging technology have shifted management of penetrating neck injuries from mandatory exploration to selective management. The question is now regarding optimal selection of auxiliary examinations to assess "stability" rapidly and guide clinics in managing such patients. PATIENT CONCERNS: A 56-year-old man suffered neck trauma with the right common carotid artery caused by a percussive drill. The carotid artery could not be clearly displayed in computed tomography (CT) angiography imaging. DIAGNOSES: Penetrating neck trauma due to percussive drill bit with common carotid artery injury. INTERVENTIONS: X-ray and bedside duplex ultrasound with color Doppler flow imaging were used to assess the state of trauma and the foreign body was removed under general anesthesia. OUTCOMES: The patient was discharged at postoperative day 10 with no complication. The patient had no sequelae from this injury at 6-month follow up. LESSONS: X-ray provides a comprehensive assessment of damage, and can efficiently detect foreign bodies in the skull and cervical vertebrae. Duplex ultrasound to be a viable method to exclude macrovascular injury in unstable patients who are not eligible for computed tomography angiography (CTA) or catheter angiography imaging. Widely available duplex ultrasound and x-ray should be considered in emergency situations.
