Analysis Of Effects Of Two Different Tumor Basal Dura Treatment On The Prognosis Of Intraspinal Meningiomas

Objective: To explore the effects of two different tumor basal dural treatments on the prognosis of intraspinal meningiomas.Method: Retrospective analysis of 37 patients who underwent intraspainal meningioma resection during January 2011 to January 2015 in shengjing hospital,China medical university.According to the different treatment of tumor basal dural,these patients are divided into two groups: group 1(meningioma + inner part of the basal dura resection)and group 2(meningioma resection + inner part of the basal dura electrocauterization).There were 18 cases in group 1: 4 males and 14 females aged from 31 to 72 years(averaged 53.33 years),including 5 cervical cases and 13 thoracic cases.There were 19 cases in group 2: 6 males and 13 females aged from 23 to 75 years(averaged 53.33years),including 2 cervical cases and 17 thoracic cases.Postoperative complications: 1)infection of central nervous system: occurred in 3 cases of group 1,and 2 cases in group2.All of these 5 cases were completely cured by lumbar drainage of cerebral-spinal fluid(CSF);2)CSF leakage of the incision: occurred in 1 case of group 1,which was completely cured by lumbar drainage of CSF.There was no CSF leakage of the incision occurred in the cases of the group 2;3)tumor recurrence: occurred in 1 case of group 1,and 4 cases in group 2.All of the tumors of these 38 patients were completely resected.Meningiomas were confirmed by postoperative pathological examination.Statistical method was used to analyze the differences between the two groups in postoperative infection of central nervous system,CSF leakage of the incision,and tumor recurrence.Result: 1)There was no statistical difference between the two groups in postoperative infection of central nervous system and CSF leakage of the incision(P > 0.05);2)Compared with that of the group 1,the postoperative tumor recurrence rate of the group2 was significant higher(P<0.05).Conclusion: Resection of meningioma and inner part of the tumor basal dura is a better neurosurgical method to reduce the recurrence rate of intraspinal meningiomas.
