Abstract
Objective To evaluate the clinical efficacy of posterior laminectomy for patients with intraspinal schwanno‐ma.Methods 50 patients with intraspinal schwannoma in our hospital were selected ,who were treated with posterior laminec‐tomy. All the patients were followed up for at least 12 months. The clinical efficacy was observed.Results All 50 patients’ tumors were successfully removed ,and confirmed as schwannoma by pathological examination. Operation time was 2‐4.5 h , (3.0 ± 0.8) h on average ;blood loss was 200‐600 mL ,(380 ± 60) mL on average. 7 patients with varying degrees of cerebro‐spinal fluid leakage ,but stopped after given to pillow supine ,local pressure ,a sufficient amount of fluid and cerebrospinal fluid leakage. 2 patients of cervical cancer with sensory disturbances on the move ,and with upper limbs motor dysfunction ,the MRI examination to consider a diagnosis of spinal cord ischemia‐reperfusion injury. With high dose methylprednisolone dehydration and nutrition nerve treatment ,symptoms improved and gradually disappear within 2 weeks. 41 patients were available for final follow‐up ,and the follow‐up period was 12‐38 months ,(24.6 ± 4.0) months on average. During follow‐up period ,no tumor recurrence was observed ,and no spondylolisthesis and instability was appeared. Postoperative neurological recovery Frankel’s grade:D ,10 cases and E ,31 cases.Conclusion Posterior laminectomy treatment of spinal nerve sheath tumors may be fully exposed to the tumor ,and complete removal of the tumor ,which has better clinical efficacy. The prevention and treatment of cerebrospinal fluid leakage and nerve root supplying tumor was the key for a successful surgery.关键词
