立体定向显微手术切除脑内病灶

目的探讨立体定向显微手术切除脑内病灶的可行性。方法应用F.L.FischerZD定向仪，CT定位，对24例脑重要功能区及脑深部病灶进行立体定向开颅显微手术。病变性质胶质瘤14例，脑囊虫2例，转移瘤2例，脑脓肿1例，脑膜瘤1例，动静脉畸形(AVM)1例，海绵状血管瘤1例，异物1例，炎性肉芽肿1例。病灶直径为1.5～3.0cm，＞3.5cm

Resection of cerebral lesions by stereot actic microsurgical operation

Objectiv e：To study the fensibility of resecting cerebral lesions by stere otactic microsurgical operation.Methods：Fischer CT stereotactic apparatus was used.Of the 24 ca se of cerebral lesions,14 were located in the s ubcortex of movement or feeling area,3 cases in the subcortex of language center, 6 cases i n the deep brain and 1 case in occipital lobe. Epilepsy, hemisphere, dysphasia h eadache and vomiting were the most common clinical manifestations. There were 1 4 cases of glioma, 2 cases of cerebral cysticercosis,2 cases of metastastic tumo rs, 1 cases of brain absess, meningioma, AVM, cavernous angioma, foregin objects and inflammatory granuloma respectively. The diameter of the lesions was 1.5～3 .0 centimeters,with 2 cases more than 3.5 centimeters. Total resection was perfo rmed by steretastic microsurgical operation.Results：After the operations,the symptoms of all the patients g radually alleviated. Except that the 2 cases with metastastic tumor died of di ffu se metastasis,the others recovered, whithout operative complication or death.Conclusion：The lesions located in the deep brain or important f unction area, if the lesion's diameter is less than 3 centimeters and the margin is clear, stereotastic microsurgical operation is more appropriate.
