Performing resection of complex neck tumors with cervical spine reconstruction

The patient, female, 50 years old, had numbness and weakness of the limbs in the past two years, and had consulted the Department of Spine Surgery of several tertiary hospitals in the province. MRI examination of the cervical spine showed a huge tumor in the neck, which had destroyed the cervical vertebral body and protruded into the cervical spinal canal to oppress the spinal cord, and had a close relationship with the cervical nerves and blood vessels. After admission to our department, further relevant examinations were performed and a detailed diagnosis and treatment plan was formulated: cervical MRI (Figure 1) and CT 3D reconstruction (Figure 2) were performed to understand the destruction of the cervical vertebral body, and DSA cerebral angiography was performed to understand the blood supply of the tumor and its relationship with the cervical blood vessels. The results of the examination showed that the tumor was located in the left side of the neck, with a large volume and deep location, eroding the vertebral body from the left side of the cervical 7 vertebrae and protruding into the vertebral canal, and the spinal cord was obviously compressed. The left common carotid artery and the left vertebral artery were closely related to the tumor, and both were displaced by the tumor. Jiang Zheng, Department of Neurosurgery, Qilu Hospital, Shandong University, combined with the advantages of multidisciplinary cooperation and complementarity of our hospital, asked Li Jie, Director of Ultrasound Department, to consult with the patient, and gave him ultrasound-guided puncture biopsy of the cervical mass to understand the nature of the tumor as a benign nerve sheath tumor, which further strengthened the patient’s and his family’s determination of requesting surgical treatment. Dr. Lei Dapeng, Deputy Chief Physician of Department of Otorhinolaryngology, was invited to consult with the patient and drew up a joint surgical plan. After completing all preoperative examinations and preparations, the patient underwent surgery on December 12 under general anesthesia. Dr. Qian Ye of ENT was asked to assist in isolating and revealing the free internal carotid artery, internal jugular vein and nerve tissues during the operation. Dr. Jiang Yuquan, Director of Neurosurgery, Dr. Jiang Zheng, Dr. Wang Lei, Deputy Director of Neurosurgery, and Dr. Han Lizhang performed the surgery for the patient. During the operation, the tumor was found to be extremely tough and widely involved, which made resection difficult. The tumor had eroded most of the cervical 7 vertebrae and protruded into the cervical spinal canal. The cervical medulla was obviously compressed, and the internal jugular vein was displaced externally, reaching the upper edge of the pleura below and the level of the cervical 6 vertebrae above. Ultrasonic suction was applied to resect the tumor in pieces, and after sufficient intra-tumoral decompression, the adhesions between the tumor envelope and the surrounding tissues were carefully separated, and the anterior cervical and eroded cervical 7 vertebral body and the tumor protruding into the spinal canal were resected. Afterwards, the bone was taken from the patient’s left iliac bone and placed in a titanium cage, and an appropriately sized implanted titanium cage was placed in the cervical 6-thoracic 1 vertebral space to rebuild the vertebral body, and a connecting titanium plate was taken for fixation. The surgery lasted nearly 9 hours, and the tumor was basically completely resected. After the operation, the patient’s numbness of the limbs was significantly reduced and the muscle strength of the limbs was improved compared with the preoperative period. Postoperative review of cervical spine plain film and CT showed satisfactory results (Figures 3 and 4). In recent years, under the leadership of Jiang Yuquan, the Neurosurgery Spinal Cord Specialty Group of our hospital has gradually carried out the spinal canal tumor resection with internal fixation and bone grafting and fusion, and the cervical, thoracic, and lumbar intervertebral disc herniation resection with internal fixation and bone grafting and fusion. The mature microscopic and minimally invasive operation techniques of neurosurgery combined with the increasingly skillful spinal internal fixation and fusion and reconstruction techniques have relieved the pain of more and more patients with spinal cord lesions.
