The Department of Neurosurgery for High Cervical Spinal Cord Tumor has successfully completed several cases of difficult high cervical spinal cord occupancy surgery, which relieved the pain of spinal cord tumor patients. The patient was operated under general anesthesia with tracheal intubation. The tumor was located ventral to the spinal cord and originated from a nerve with intact envelope and tough, fish-like texture. After determining the location of the tumor, the microsurgical technique was used to gently operate and carefully separate the tumor tissue, which was eventually removed completely without damage to the spinal cord. The spinal cord is the primary center of muscle, glandular and visceral reflexes, and is the intermediate unit that closely links the activities of various parts of the body with those of the brain. Once a lesion occurs in the spinal cord, it can cause disorders of motor, sensory, sphincter function and vegetative nerve function, mainly manifesting as nerve root damage in the plane where the tumor is located and symptoms and signs of involvement of the pyramidal tract below that level, which can easily lead to limb paralysis. The higher the spinal cord lesion, the higher the risk. Tumors in the high cervical segment are prone to combined respiratory muscle involvement, secondary respiratory weakness and pulmonary inflammation, and spinal cord injury in the high cervical segment is more likely to lead to tetraplegia. When the spinal cord is completely dysfunctional for more than six months, even if the compression lesion can be completely removed, the functional recovery is not satisfactory. Therefore, he also reminded that patients suffering from spinal cord tumor should choose surgery as early as possible, taking into account the pathological nature, location and size of the tumor, as well as the patient’s age, symptoms, general condition and family wishes.
