The authors describe the technique used to precisely locate, before surgical ablation, small superficial or deep seated intracerebral lesions. When they are superficial, a burrhole is placed above the lesional site, that is reconstructed by superimposing the CT image onto a plain film radiogram taken during stereotaxy. Deep seated lesions are localized by inserting a guide under stereotaxy, prior to open surgery, which will lead the neurosurgeon without error from the cortex to the lesion. 37 observations are reported where this technique lead to a greatly simplified intervention with minimal cortical damage.
作者描述了在手术切除前精确定位浅表或深部脑内小病灶的技术。对于浅表病灶，在病灶部位上方钻一个骨孔，通过将CT图像与立体定向期间拍摄的平片X线照片叠加来重建。对于深部病灶，在开放手术前通过立体定向插入一根导针进行定位，这将引导神经外科医生无误地从皮质到达病灶。报告了37例观察病例，该技术使干预大大简化，皮质损伤最小。
