Abstract
BACKGROUND: Cervical spondylectomy for the treatment of cervical tumors is traumatic, causes bleeding, and is risky. This study reports on the experience with minimally invasive cervical spondylectomy for a cervical metastasis and reviewed the literature on cervical spondylectomy. The purpose was to reduce the risk and trauma of spondylectomy.
CASE SUMMARY: A 60-year-old woman presented with cervical pain and radiating pain in the left upper limb for more than 2 mo. Preoperative diagnosis was C4 metastasis of thyroid cancer. Preoperative visual analogue scale score was 5. American Spinal Cord Injury Association (ASIA) grade was E. Tomita classification was 7. Weinstein-Boriani-Biagini (WBB) classification was A-D, 3-9. Tomita score was 5. Modified Tokuhashi score was 9. Spinal instability neoplastic score (SINS) was 13. The patient underwent minimally invasive cervical spondylectomy on September 28, 2017. The operative time was 200 min; the estimated blood loss was 1200 mL. The operation was successful, without complications. The postoperative visual analogue scale score was 0. The patient remained classified as ASIA grade E at the last follow-up. She accepted regular iodine-131 therapy postoperatively. The serum thyroglobulin (Tg) level of this patient was 299.02 ng/mL at 1 mo after the operation and was 13.57 ng/ mL at the last follow-up. There was no local recurrence at the 25-mo follow-up, according to images, single-photon emission computed tomography, and serum Tg levels. Obvious ossification and solid fusion of C3-C5 were found at the last follow-up.
CONCLUSION: Minimally invasive cervical spondylectomy with tubular retractor could minimize soft tissue trauma, intraoperative traction injury, and paraspinal muscle injury, accelerating postoperative recovery. This technique requires a rich experience in cervical spine surgery with tubular retractors, so that surgeons can visualize the anatomical structure in a small field.
