等体积胶质瘤摘除术

目的：利用立体定向技术和ＭＲＩ的三维成像技术结合，对颅内胶质瘤实行等体积切除。方法：使用Ｌｅｋｓｅｌ－Ｇ或ＡＳＡ－６０２型定向仪，１．０Ｔ的ＭＲＩ对颅内病灶进行三维成像，立体定位颅内病灶，选择适当头皮切口及环钻开颅，术中配合超声刀进行等体积切除胶质瘤。结果：所有２５例胶质瘤均做到了全切除，术后一过性面瘫８例，癫痫发作２例，语言障碍１例，均能恢复。无伤口感染，无脑脊液漏，无手术死亡率。结论：立体定向技术与ＭＲＩ三维成像技术相结合，能对颅内病灶如胶质瘤做到等体积切除，手术侵袭性小、安全、快捷，易被病人接受

Volumetric resection of intracranial glioma

Objective:With the help of gtereotaxy and MRI three-dimensional imaging techonlogy,volumetric resection of brain glioma can be done.Methods:After fixing the frame on the patient's head,3-D images of the glioma can be got by MRI Scanning All of these information can help a neurosurgeon to design the scalp incision and select apropriate tryph and resect the gliomas completely with CUSA.During the resection,neurosurgeon can consider the optical trajectory to minimize risk to eloquent areas and vascular structures.Results:The planned volume was resected in 25 patients who had got brain gliomas.8 patients got transient palsy and recovered soon.Local seizure occured in 2 cares. One patient got aphasia who recovered later.No mortality due to the operation, no infection of the incision.Coclusion:The conbination of stereotaxy and MRI 3-D imaging technology provides a good control of brain gliomas resection to optimize amount of tumor removal with minimal trauma to surrounding brain tissues in a safe and cost-effective manner.
