Neurofibromatosis-1 (NF1) presents complex challenges due to its multisystemic effects, including kyphoscoliosis, dural ectasia, and arteriovenous fistulas (AVF). We present a case of a 31-year-old male with NF1 exhibiting severe cervical kyphoscoliosis, dural ectasia, a bisected cervical cord, and an arteriovenous fistula, highlighting the intricacies of managing such intricate cases. Rapid weakening in the patient’s right arm and leg prompted imaging revealing severe cervical kyphotic deformity and a dural fold dividing the spinal cord. Surgical intervention addressed a high-flow arteriovenous fistula involving the right vertebral artery and an epidural vein, necessitating sacrifice of the artery. Posterior fusion and laminectomy were performed, resulting in stable neurological status postoperatively and significant improvement in sensory loss and weakness at three months. This case underscores the importance of a tailored posterior-only approach, involving dural fold release, to allow the spinal cord to relocate to a less tense position, thus demonstrating effective decompression in complex NF1 cases with concurrent kyphotic deformity and vertebral artery AVF.
