Spinal cavernous disease is a slowly progressive degenerative lesion of the spinal cord that causes the central canal to enlarge or form a tubular cavity under the influence of pathogenic causes. In cases of hydrocephalus and increased intracranial pressure, lateral ventricular-ventricular shunt is performed first; 2. For patients without obvious atlanto-occipital deformity and subxiphoid herniation, intradural exploration and cavity-subarachnoid shunt can be performed in the corresponding part of the lesion. Before surgery, early stage patients have limited and mild symptoms, while late stage patients mostly have limb dysfunction, so they should be given life care, massage local skin and move their limbs. In the postoperative period, the patient should be turned in a straight line. Closely observe the movement of the limbs, pay attention to the sensory plane, and be alert to the occurrence of spinal cord hematoma. For high cervical spinal cord cavity, the patient should be given a cervical brace. And postoperative complications and prevention should be paid attention to, dehydration and glucocorticoid treatment if necessary. If necessary, dehydration and glucocorticoid treatment should be given. Since the interval between the stages of the disease can be several years, it is important to diagnose and perform surgery early.
