磁共振导向的立体定向开放直视手术切除脑内小病灶24例分析

目的:探讨脑立体定向开放手术切除脑内小病灶的经验体会及手术效果。方法:对24例病变直径在0.4cm～3.5cm的患者采用磁共振导向脑立体定向显微镜下切除病灶。结果:24例患者的颅内病变全部行显微手术切除,无手术并发症及死亡。13例继发性癫(?)中10例术后停止发作,另3例发作显著减少。结论:对于MRI检查显示的界限清楚的最大直径<3.5cm脑深部MRI导向的立体定向开放手术是一种简便、定位准确、微侵袭、安全且疗效满意的手术方法。

Analysis of 24 cases of minor lesions in brain by stereotaxic open surgery using MRI-directed stereotactic technich

Objective Through the treatment to the intracranial lesions by MRI-guiding stereotaxic open surgery, discuss the experience and operation result in clinics. Method Applying Leksell-G type stereotaxic apparatus to localize the intracranial lesions in 3-D, stereotactically craniatomy to remove the lesions of 24 cases under microscope. Results No operative morality among the 24 cases, the symptoms of epilepsy in 13 cases totally disappear among the 10 cases, attack frequency diminish dramatically in 3 cases after operation. Conclusion MRI-guiding stereotactic technich characters include little injury to cerebral tissue, highly operative safety, little post-operative complication, quick recovery, which determine this technich is the optimal method in treating the intracranial minor lesions.
