ABSTRACT
PURPOSE: This article aims at evaluating the results of treatment which excise the intradural extramedullary tumor using surgical microscope, mainly concerned by the field of orthopaedic surgery. MATERIALS AND METHODS: A retrospective review was carried out on 11 cases who were operated on for the excision of intradural extramedulary tumor in two hospitals from June 2001 to May 2007. Of the 11 cases, there were 3 males, and 8 females with an average age of 62.4 (33-78) years. Average follow-up period is 18.8 (1-78) months. Patients were diagnosed by MRI and pathological diagnosis was analyzed. The clinical evaluation was made by the index of VAS (visual analogue scale) and Cooper- Epstein grade. RESULTS: 7 cases were Schwannoma and 4 cases were meningioma. The VAS take a favorable turn from average 9.4 before practice to final follow-up 2.4, and the Cooper-Epstein grade take a favorable turn from average 2.4 to final follow-up 0.7 CONCLUSION: A fine result of excision of the intradural extramedullary tumor with using surgical microscope could be acquired even in the field of orthopedic surgery.

The surgical treatment of spinal arteriovenous malformations has been improved markedly during the last several years by use of the operating microscope and microsurgical instrumentations. The possibility of total removal has been viewed pessimistically. However, total extirpation of spinal intramedullary arteriovenous malformation(AVM) can be possible by use of intraoperative monitoring of the somatosensory evoked potentials(SEPs). Authors report a case of spinal intramedullary glomus AVM which was successfully removed with intraoperative monitoring of the SEPs and discuss surgical management. Intraoperative monitoring of the SEPs to determine the safety of removing of the spinal intramedullary AVM is stressed.
