RESUMEN
Objective:To investigate the effect of treatment of spinal meningioma with microsurgical procedures.Methods:From January 2003 to March 2022, there were 120 patients who had spinal meningioma and treated in the Department of Neurosurgery, The First Affiliated Hospital of Sun Yat-sen University. Their clinical data were retrospectively analysed. Of the 120 patients, there were 90 females and 30 males, aged from 14 to 85 (average, 54) years old. According to McCormick Classification, 29 cases were in grade I, 59 cases were in grade II, 25 cases were in grade III, and 7 cases were in grade IV. They were all underwent microsurgery. Patients were followed up by outpatient service within 3 months after surgery, then reviewed by outpatient visits and telephone interviews. McCormick's classification method and MRI examination were used to analyse the neurological and imaging changes of the patients before and after the surgery.Results:A total of 113 patients had complete resection and 7 had the resection of most part of the spinal meningioma. No infection, cerebrospinal fluid leakage, other complications and death occurred. Three months after surgery, 95 patients achieved the improvement or even completely disappearance of symptoms (such as numbness, pain, limited movement, etc.). There were 23 patients who had the symptoms unchanged as what before the surgery. Two patients had the symptoms worsened after the surgery. At 3 months after surgery, 95 cases (79.2%) improved, 23 cases (19.2%) were stable, and 2 cases (1.6%) aggravated. According to McCormick classification method, 92 cases were in grade Ⅰ, 15 cases were in gradeⅡ, 10 cases were in grade Ⅲ, and 3 cases were in grade Ⅳ. MRI scans showed that the dural sac were well refluxed, and no recurrence was found.Conclusion:Microsurgery is safe and effective for removal of spinal meningioma, with significant improvement in symptoms with fewer complications.
RESUMEN
Objective To investigate the microsurgical effect of spinal cord Intramedullary cavernous hemangioma.Methods The clinical data of 23 patients with spinal cord Intramedullary cavernous henangioma from January,2003 to March,2017 were analyzed retrospectively.McCormick clinical neurological function classification method and MRI examination were used to analyze the changes of neurological function and imaging changes beforeand-after operation.MRI and assess nerve function were reviewed 6-12 months after discharge.Results Twentytwo cases were totally resected,and subtotal excised in 1 case.The symptoms improved and even disappeared completely in 17 cases.There was no obvious improvement in 4 cases,2 cases were worse and no death cases.Twentyone cases were followed-up.The follow-up time was 3 months-9 years,and no tumor recurrence was found.Among the 14 cases of clinical neurological function Ⅰ-Ⅱ,10 cases recovered rapidly and most of the symptoms improved or even disappeared.Three cases had no obvious change.The other 1 case aggravated symptoms;Six cases of Ⅲ-Ⅳ patients in 7 cases of postoperative recovery,and 1 case of no change.According to preoperative neurological function grade Ⅰ-Ⅱ and Ⅲ-Ⅳ,the treatment effect of patients was compared,the difference was significant (x2=5.25,P＜0.05).Conclusion Microsurgical resection of spinal cord Intramedullary cavernous hemangioma is safe and effective.The preoperative nerve function,the relationship between the tumor and the spinal cord,and the surgical skill and the degree of resection are the important factors that affect the prognosis.
RESUMEN
Objective To detect the expression of survivin protein in intramedullary gliomas and evaluated the clinical significance of the survivin expression. Method Seventeen cases of intramedullary gliomas were removed by using microsurgical technique.It composed of 8 cases of ependymomas and 9 ones of astrocytomas.The patients were followed up by MRI scanning periodically.The survivin protein expression of the intramedullary gliomas were examined by immunohistochemical stain (SP). Results Total resection of the tumor was obtained in 7 cases of ependymomas and subtotal resection was undertaken in the other one case.For 9 cases of astrocytomas,total resection of the tumor achieved in 3 cases,subtoal resection in 5 cases and partial resection in one case.Survivin expression was detected in 2 samples of ependymomas and 6 ones of astrocytomas.2 astrocytoma cases were moderate positive staining,who suffering from intracranial and vertebral subarachnoid dissemination of the tumor. Conclusion The result of microsurgical treatment for intramedullary ependymomas is satisfactory.The survivin expression in astrocytoma samples is significantly higher than that in ependymoma.Moderate positive staining may correlated with subarachnoid dissemination of the tumor.
