Surgical treatment for kyphotic deformity after anterior cervical fusion with a severely tortuous vertebral artery: a case report.

We performed salvage surgery on a patient with kyphotic deformity after anterior cervical fusion with a tortuous vertebral artery (VA). A 69-year-old woman had undergone anterior cervical corpectomy and fusion 12 years ago. Her cervical alignment gradually became kyphotic because of bone graft collapse. Ten years after surgery, she experienced severe neck pain, recurrence of myelopathic symptoms and difficulty in keeping her head straight. The patient was diagnosed with rigid cervical kyphosis at C4–6 vertebral levels, with the right tortuous VA invaginating into the C4 vertebral body. We selected a three-stage, anterior–posterior–anterior approach to reduce cervical alignment. The key to a successful surgery in this case was to retract the tortuous VA within the C4 vertebral body, followed by total uncinectomy. Careful preoperative VA evaluation was a decisive factor in surgical planning. [ABSTRACT FROM AUTHOR]
