ABSTRACT
Objective:To evaluate the diagnosis, surgical treatment, and neurological function recovery after surgery of patients with intraspinal tumors. Methods:The clinical data of 69 patients who suffered from intraspinal tumors and underwent surgery from Janu-ary 2008 to December 2012 were retrospectively analyzed. Neuroimaging and ASIA scoring were performed to examine the pathologi-cal characteristics of tumors and the neurological function of these patients before and after treatment. The major factors affecting prognosis were also probed, and the average follow-up period was 12.2 months. Results:Of the total cases, 62.3%showed intradural extramedullary intraspinal tumors located in the thoracic vertebra. Neurilemoma (Schwannoma) and meningioma were the most com-mon pathological types (53.5%). Posterior approaches with hemi-and complete-laminectomy were conducted to expose the intraspi-nal tumors, and the separation and removal of the tumors located at the cervical and thoracic levels were aided with surgical microsco-py. The main clinical symptoms, including back pain, radicular neuralgia, sensory disturbance, and motor dysfunction, were significant-ly improved after surgery, and this observation was supported by the follow-up ASIA scores before and after treatment. Of the in-volved cases, 91%were successfully treated, and their tumors were totally resected. Conclusion:Total or subtotal intraspinal tumor re-section enhanced with surgical microscopy could achieve satisfactory clinical results through posterior hemi-or complete-laminectomy.
