Direct Percutaneous Puncture and Glue Embolization of a Cervical Prevertebral Bleeding Pseudoaneurysm Using Cone-Beam CT Navigation Technology

A 91-year-old man presented emergently with anterior neck pain, severe dysphagia, and neck expansion after a fall 1 day earlier. His oxygen saturation level was 88% on 4 L of oxygen. A triple-phase computed tomographic (CT) angiogram of the neck showed a massive prevertebral hematoma from a bleeding pseudoaneurysm (Fig 1). A right vertebral artery angiogram showed the prevertebral pseudoaneurysm to be supplied by a tiny muscular branch that was too small for selective transarterial catheterization (Fig 2).
