开放性立体定向显微手术在颅内小病灶切除中的临床应用

Treatment of brain lesion by opening stereotactic microneurosurgic operation

目的 探讨开放性立体定向微创切除颅内小病灶的方法。方法 局麻安装CRW头架后 ,行CT或MRI三维扫描 ,定位后局麻下用自制系列环钻开颅 ,显微镜下切除颅内病灶。伴有癫痫的病人 ,常规行术中皮层电图监测 ,必要时行致痫灶切除或软膜下横纤维切断术。结果 本组 34例病灶中 32例全切除 ,2例大部切除。术后 2例肢体瘫痪一过性加重 ,1例术后早期出现暂时性运动性失语 ,其余病人神经功能保留良好。 13例癫痫起病者 ,12例消失 ,1例发作次数减少。结论 在开放性立体定向技术定位下 。

Objective To explore the method of small brain lesion resection.Methods Using CRW brain stereotactic apparatus, with the help of CT and MRI images, cranial trepanation in local anesthesia, cut the brain lesions by microscope.Results Total lesion resection was achieved in 32 of the 34 cases, subtotal in 2. The 13 epileptic patients,12 cases symptom disappear.Conclusion With the help of stereotactic technology, microneurosurgic operation is an effective method to resect small brain lesion.
