METHODS Vertebral artery injury is a low-frequency but high-mortality injury. The surgical approach to a bleeding vertebral artery injury is one of the most difficult procedures in trauma surgery.A 64-year-old woman was transported to our emergency department after being stabbed in the middle side of the right neck with a large kitchen knife. Her initial hospital examination indicated a shock state, and computed tomography images revealed a right vertebral artery injury. We undertook angiography and transcatheter arterial embolization before the surgical operation. RESULTS The patient suffered right upper extremity paralysis due to brachial plexus injury and was transferred to another hospital for rehabilitation on the 24th hospital day. CONCLUSIONS Computed tomography angiography for diagnosis and interventional radiology treatment are useful for the management of penetrating neck trauma. Transcatheter arterial embolization for vertebral artery injury is safe and allows for easy control of bleeding compared to a surgical procedure.
