Abstract
A case of a 47-year-old man with weakness secondary to ossification of the posterior longitudinal ligament is presented. During removal of the ossified ligament, the patient's dominant right vertebral artery was injured. Although the bleeding from this artery was controlled intraoperatively, the patient developed an expanding cervical hematoma on the 3rd postoperative day. An angiogram demonstrated a large pseudoaneurysm of the right vertebral artery. The patient was taken back to the operating room where the cervical hematoma was removed, and direct repair of the pseudoaneurysm of the vertebral artery was performed. The previously reported cases of pseudoaneurysms of the extracranial vertebral artery are reviewed. We advocate the use of direct vascular repair as the treatment of choice in these lesions.
