Vascular blowouts are devastating complications of head and neck oncologic surgery that are easily diagnosed with oropharyngeal or external bleeding. We present herein a case of a pseudoaneurysm of the subclavian artery that mimicked recurrent head and neck carcinoma. Vascular lesions arising in the base of the neck may present with few signs of vascular injury. Head and neck surgeons should be aware of this unusual complication to avoid a potentially life-threatening event. We report difficulties in diagnosing subclavian pseudoaneurysm, a review of the vascular injuries related to this condition, as well as approaches to bleeding at the base of the neck.
